A comparison of combined arthroscopic triangular fibrocartilage complex debridement and arthroscopic wafer distal ulna resection versus arthroscopic triangular fibrocartilage complex debridement and ulnar shortening osteotomy for ulnocarpal abutment syndrome.

PURPOSE: Treatment of ulnocarpal abutment (UAS) syndrome involves decompression of the pressure and impingement, or abutment of the ulnocarpal articulation. Debridement of triangular fibrocartilage complex (TFCC) tears alone in the patient with UAS may have a failure rate of as much as 25% to 30%. Ulnar shortening osteotomy (USO) can be an effective treatment of failed TFCC debridement. Good results have been reported with combined arthroscopic TFCC debridement and mechanical arthroscopic distal ulnar resection. Similar results have been reported with both ulnar shortening osteotomy and open wafer distal ulnar resections in the UAS patient. Because all of these treatment choices appear to yield similar relief of symptoms, determination of the optimal treatment protocol remains a point of debate. The purpose of this study was to evaluate 2 different surgical treatments for UAS. TYPE OF STUDY: Retrospective review. METHODS: Eleven combined arthroscopic TFCC debridement and arthroscopic distal ulna resections (arthroscopic wafer procedures; AWP) were compared with 16 arthroscopic TFCC debridement and USOs. All patients had diagnostic wrist arthroscopy and arthroscopic TFCC debridement. All patients presented with ulnar wrist pain or neutral or positive ulnar variance, and all experienced at least 3 months of failed conservative management. RESULTS: At mean follow-up times of 21 and 15 months, respectively, 9 of 11 patients showed good to excellent results after arthroscopic TFCC debridement and AWP compared with 11 of 16 after arthroscopic TFCC debridement and USO. A statistically significant difference (P <.05) in the complication rates was identified, including secondary procedures and tendonitis. One secondary procedure and 2 cases of tendonitis were seen in the arthroscopic wafer group. CONCLUSIONS: Combined arthroscopic TFCC debridement and arthroscopic wafer procedure provides similar pain relief and restoration of function with fewer secondary procedures and tendonitis when compared with arthroscopic TFCC debridement and USO, for the treatment of UAS. LEVEL OF EVIDENCE: Level III.

The arthroscopic treatment of unicompartmental gonarthrosis: a five-year follow-up study of abrasion arthroplasty plus arthroscopic debridement and arthroscopic debridement alone.

A retrospective review with a mean follow-up time of 60 months was performed on 126 patients who had treatment of unicompartmental gonarthrosis with either abrasion arthroplasty plus arthroscopic debridement or arthroscopic debridement alone. Fifty-nine patients had abrasion arthroplasty and arthroscopic debridement, and 67 patients had arthroscopic debridement alone. All patient had stage II Ahlbäck changes roentgenographically, as well as Outerbridge stage IV changes arthroscopically in the involved compartment. All the knees were evaluated postoperatively at a minimum of 60 months, utilizing The Hospital For Special Surgery Knee Scoring System. In the group treated with abrasion arthroplasty, 51% had good to excellent results, 16% had fair results, and 33% had poor results. The conditions of ten of the patients who had poor results actually became worse subsequent to their abrasion arthroplasty. In the group that had arthroscopic debridement, 66% had good to excellent results, 13% had fair results, and 21% had poor results. The conditions of 12 of the patients who had poor results actually became worse subsequent to the arthroscopic debridement.

Pigmented villonodular synovitis of the knee. The results of total arthroscopic synovectomy, partial, arthroscopic synovectomy, and arthroscopic local excision.

Twenty-five patients who had had a diagnosis of pigmented villonodular synovitis of the knee were followed for an average of four and one-half years (range, two to ten years) after arthroscopic treatment. Five patients had had localized lesions and had been managed with local resection; all five had improvement, with no apparent recurrence. The remaining twenty patients had had diffuse disease. Of these twenty, eleven had had a complete arthroscopic synovectomy. All eleven had definite improvement in pain and function, and almost all had a decrease in synovitis and an increase in the range of motion of the knee; the disease recurred in only one. The other nine patients had had a partial arthroscopic synovectomy. Although most had some improvement in function and range of motion and a decrease in pain and synovitis, the disease recurred in five of the nine. Thus, in the patients who had had diffuse pigmented villonodular synovitis, the rate of recurrence was lower in those who had had a complete arthroscopic synovectomy than in those who had had a partial arthroscopic synovectomy (p = 0.01).

The arthroscopic square knot: a biomechanical comparison with open and arthroscopic knots.

PURPOSE: To compare the loop and knot security of arthroscopic square knots with other arthroscopic and open knots with the use of 2 commonly used suture types. METHODS: Five knot configurations were tested 12 times each. The arthroscopic square knot was compared with the open square knot, arthroscopic and open half hitches with alternating posts, and the Duncan loop. Load-to-failure testing was performed at a rate of 1.25 mm/sec, and cyclic testing was performed between 7 N and 30 N at a rate of 1 N/sec for 50 cycles. Two suture types were tested: No. 2 Ethibond suture and No. 2 FiberWire. RESULTS: Among the No. 2 Ethibond sutures, the arthroscopic Duncan loop had the highest load-to-failure at 165 N. The remaining knot types failed at between 142 N and 148 N. The load at 3 mm of lengthening was between 100 N and 120 N for all knots. The No. 2 FiberWire failed at higher loads than the No. 2 Ethibond suture for all knot types except the Duncan loop. The arthroscopic half hitches, arthroscopic square knots, and open half hitches all failed at between 220 N and 264 N. The open square knot failed at 188 N, and the Duncan loop failed at 147 N. The load at 3 mm of lengthening was between 130 N and 165 N for all knots except the Duncan loop, which failed at 95 N. With cyclic testing, arthroscopic square knots performed better than all knot types, but the differences were clinically insignificant. CONCLUSIONS: Arthroscopic square knots have the same or greater strength when compared with other arthroscopic or open knots tied with the same suture type, and they perform as well or better in the face of cyclic loads. Good knot security can be attained with all of the knots tested, regardless of suture type. Equivalent knots tied with No. 2 FiberWire fail at higher loads, except for those tied with the Duncan loop. CLINICAL RELEVANCE: Arthroscopic square knots can be used in the clinical setting with no compromise in function when compared with open square knots.

Diagnostic evaluation of an ultrathin 15,000 fiberoptic arthroscope: comparison of arthroscopic and histologic findings in a sheep model.

PURPOSE: An ultrathin 15,000 fiberoptic-based arthroscope was evaluated for the detection of osteoarthritic intra-articular pathologies in sheep temporomandibular joints. MATERIALS AND METHODS: Osteoarthritis was bilaterally induced in the temporomandibular joints in sheep. Twenty osteoarthritic temporomandibular joints were arthroscopically examined and rated with use of the ultrathin arthroscope. The arthroscopic observation was then compared with the histologic findings. RESULTS: The arthroscope provided excellent vision of the osteoarthritic joints. Correlation between arthroscopic and histologic findings was 80%. CONCLUSION: The recently developed ultrathin (15,000) arthroscope was found to be a highly reliable and efficient tool to diagnose joint space pathologies of the osteoarthritic temporomandibular joint.

Arthroscopic lysis and lavage in different stages of internal derangement of the temporomandibular joint: correlation of preoperative staging to arthroscopic findings and treatment outcome.

PURPOSE: The study was designed to evaluate the outcome of standard arthroscopic lysis and lavage for internal derangement with various levels of severity by comparing the preoperative staging with arthroscopic findings and subsequent success rates. PATIENTS AND METHODS: Temporomandibular joint disorder in 23 patients (26 joints) who underwent arthroscopic lysis and lavage was preoperatively classified as Wilkes stages II-V based on the clinical and radiologic (magnetic resonance imaging) findings. Recorded arthroscopic findings were scored and compared with the stages. The patients were examined both preoperatively and after a mean follow-up of 22.7 months, using objective and subjective criteria. RESULTS: The arthroscopic findings showed a correlation between increasing scores and advancing stage. Postoperatively, the patients could be clearly classified into 2 groups with either satisfactory or poor clinical outcome. Overall success rate was 78.3% (18/23). The success rates were slightly lower for patients with advanced stages than for those of stages II and III. Patients totally unresponsive to the treatment were found in all stages. CONCLUSION: Arthroscopic lysis and lavage is a preferred treatment for different stages of internal derangement. Preoperative staging and corresponding characteristics of the arthroscopic findings do not seem to correlate with the prognosis of the treatment outcome.

Failed arthroscopic meniscectomy: prognostic factors for repeat arthroscopic examination.

The authors have reviewed 44 patients retrospectively who failed arthroscopic partial meniscectomy. The study attempts to define the chances for success and to identify prognostic factors as these patients return for reoperation. Each patient had a repeat arthroscopic examination from 2 to 60 months after partial meniscectomy (average 19 months). They were reviewed an average of 31 months after reoperation (6 to 60 months), and each completed a subjective questionnaire evaluating the efficacy of their repeat arthroscopic surgery. Seventy-one percent of the patients had improvement with reoperation and were classified as good or excellent. Twelve patients (29%) did not improve and were rated poor. Ten parameters, as recorded before repeat arthroscopic examination, were investigated in an attempt to correlate each with success and to find those that are significant prognostic factors. Age of the patient, number of surgeries on the involved knee, time between arthroscopic examinations, nature of history (acute or chronic), workers' compensation or private insurance status, range of motion on physical examination prior to repeat arthroscopy, and degree of chondromalacia as seen at the first surgery were not found to correlate with the ultimate success of the patient. The presence of mechanical complaints before reoperation was a statistically significant parameter that led to a good or excellent result in 86% of the patients at follow-up. Lateral meniscal pathology seen at first partial meniscectomy gave more favorable results than medial meniscal pathology even if the patient had nonmechanical complaints. A history of reinjury between arthroscopic surgeries is helpful only if positive. In the absence of such a history, no conclusion can be drawn.

Arthroscopic fixation of osteochondritis dissecans of the knee: clinical, magnetic resonance imaging, and arthroscopic follow-up.

BACKGROUND: Optimal treatment of osteochondritis dissecans of the knee is still controversial. PURPOSE: To review a group of patients with osteochondritis dissecans of the knee who were treated with arthroscopic compressive screw fixation and who were evaluated with magnetic resonance imaging studies and a second-look arthroscopic procedure at follow-up. STUDY DESIGN: Case series; level of evidence, 4. METHODS: A total of 14 patients (15 knees) with osteochondritis dissecans of the knee were treated with arthroscopic titanium Herbert screw fixation of the osteochondral fragment. A second-look arthroscopic procedure was performed to remove hardware and to evaluate fragment stability. At final follow-up, magnetic resonance imaging studies were used to evaluate potential healing of the subchondral bone. Outcomes were clinically evaluated at a mean follow-up of 50 months (range, 25-104 months) by the Lysholm score and by the International Knee Documentation Committee score. RESULTS: At second-look arthroscopy, 14 of 15 knees showed evidence of a stable fragment with an intact smooth surface. According to magnetic resonance imaging parameters, 14 knees showed evidence of a healing process of the osteochondral fragment. The average Lysholm score improved 18 points from a mean of 79 preoperatively to 97 postoperatively, and according to the International Knee Documentation Committee score, 13 of 15 knees showed a normal result. CONCLUSION: This study suggests that magnetic resonance imaging parameters of a healed osteochondral fragment and patients with satisfactory functional results correspond with arthroscopic evidence of fragment stability. According to this study, arthroscopic fixation with compressive screws is an effective method of repair for osteochondritis dissecans of the knee.

[Diagnosis and treatment of fibrous adhesion into upper joint compartment of the TMJ. Part 2. Arthroscopic findings and arthroscopic sweeping and lysis].

A fibrous adhesion into upper joint compartment of the TMJ is indicated by a secondary pathological condition of the disk displacement. A fibrous adhesion increases resistance to motion in the joint because condyle translation disrupted. The treatment for this condition is too difficult. On this paper, we presented to arthroscopic findings of 4 cases of the fibrous change and fibrous adhesion into upper joint compartment of the TMJ (1) and arthroscopic sweeping as the treatment procedure (2). On these cases, we compared double contrast arthrotomographic findings with arthroscopic findings (3). (1) On the arthroscopic findings, banddle like fibrous adhesion, wide areal fibrous adhesion, and wide areal fibrous change of the articular surfaces were observed. These findings varied to case by cases. (2) The arthroscopic sweeping and lysis performed on this four cases. The clinical symptoms prior to arthroscopic surgery, improved post surgically in all cases. (3) The fibrous lesions in the upper joint compartment was presumed by double contrast arthrotomography that demonstrated by arthroscopy.

Arthroscopic rotator cuff repair with and without arthroscopic subacromial decompression: a prospective, randomized study of one-year outcomes.

We performed a prospective, randomized study to determine whether arthroscopic subacromial decompression changes the outcome of rotator cuff repair. We performed a power analysis to ensure statistical validity. Patients scheduled for arthroscopic rotator cuff repair were randomized to cuff repair with arthroscopic subacromial decompression (group 1) or without it (group 2). All other aspects of the surgical and postsurgical treatment were identical. We included patients with full-thickness tears limited to the supraspinatus tendon and a type 2 acromion. We excluded patients with prior surgery, those with larger tears involving two or more tendons, those with a type 1 or 3 acromion, those with workers' compensation claims, and those who had concomitant procedures (labral repair, acromioclavicular joint resection) There were 47 patients in group 1 and 46 in group 2. Minimum follow-up was 1 year (mean, 15.6 +/- 3.3 months). We recorded the American Shoulder and Elbow Surgeons (ASES) shoulder scores preoperatively and postoperatively. There was no statistical difference in postoperative ASES scores between group 1 (91.5 +/- 10.3) and group 2 (89.2 +/- 15.1) (P =.392). The change in ASES score over time did not differ between the two groups (61.1 vs 60.2, P =.363). In conclusion, within the parameters described above, arthroscopic subacromial decompression does not appear to change the functional outcome after arthroscopic repair of the rotator cuff.

Arthroscopic removal of symptomatic Bennett lesions in the shoulders of baseball players: arthroscopic Bennett-plasty.

BACKGROUND: Bennett lesions are often observed in throwing athletes, and, although usually asymptomatic, they can sometimes become painful and disturb an athlete's throwing ability. Because it is clinically difficult to determine whether a Bennett lesion is symptomatic or whether pain is from another lesion, the outcome of surgical treatment is variable. HYPOTHESIS: Arthroscopic resection of Bennett lesions diagnosed according to our criteria and arthroscopic treatment of associated lesions performed simultaneously were effective for treatment of baseball players with symptomatic Bennett lesions. STUDY DESIGN: Prospective cohort study. METHODS: The following criteria for diagnosis of a symptomatic Bennett lesion were used to identify 16 baseball players who later underwent arthroscopic removal of the symptomatic Bennett lesion (arthroscopic Bennett-plasty): 1) detection of a bony spur at the posterior glenoid rim on radiographs; 2) posterior shoulder pain during throwing, especially in the follow-through phase; 3) tenderness at the posteroinferior aspect of the glenohumeral joint; and 4) relief of pain by injection of local anesthesia. RESULTS: After a minimum follow-up of 1 year, there was no tenderness at the posteroinferior aspect of the glenohumeral joint in any of the patients. Throwing pain disappeared in 10 shoulders and was mitigated in 6 shoulders. Eleven patients returned to baseball at their previous level of competition. CONCLUSIONS: Accurate diagnosis and minimally invasive arthroscopic surgery are important for appropriate treatment of baseball players with symptomatic Bennett lesions.

Arthroscopic rotator cuff repair: transition from mini-open to all-arthroscopic.

Rotator cuff repair is one of the most common surgical procedures done in the shoulder. Traditionally, repair has required an open incision with release of a portion of the deltoid from the acromion. In the past decade, an arthroscopically-assisted, mini-open approach has gained popularity. This has been facilitated by advances in the use of arthroscopy. This trend toward a more minimally invasive approach has continued as arthroscopic techniques continue to improve and advance. An all-arthroscopic approach recently has been used for rotator cuff repairs. The arthroscopic approach offers several advantages including smaller incisions, easy access to the glenohumeral joint for treatment of intraarticular diseases, less soft tissue dissection, and less potential harm to the deltoid. The purpose of the current study is to discuss recent advances in arthroscopic and mini-open rotator cuff repair techniques and to highlight the technical aspects of the mini-open procedures that are important in making the transition to an allarthroscopic rotator cuff repair.

Diagnostic accuracy of the ultrathin arthroscope for temporomandibular joint osteoarthrosis: comparison of arthroscopic and histologic findings in a sheep model.

The diagnostic accuracy of the ultrathin arthroscope was evaluated by examination of the superior joint space of the left temporomandibular joint in 20 sheep. At the time of induction of osteoarthrosis all joints were found to be normal. Six months later the arthroscopic examination was repeated and the results compared with the histologic examination. Similar findings were seen in 11 joints (55%), with arthroscopic overdiagnosis in two (10%) and underdiagnosis in seven (35%). Eight of 16 (50%) disc perforations were found. It was concluded that underdiagnosis occurred because the whole joint space cannot be examined arthroscopically and fibrillated tissue masks bone exposure.

Comparison of an optical catheter office arthroscope with a standard rigid rod-lens arthroscope in the evaluation of the knee.

In a prospective, randomized study, 47 patients underwent arthroscopic evaluation of the knee in an operating room setting with both a standard rod-lens arthroscope and a newer flexible optical catheter fiberoptic system. The goal of the study was to assess the diagnostic accuracy of the newer catheter system, which is recommended for use in the office setting. Forty-four patients were included in the data analysis, three were eliminated because we were unable to perform an adequate examination with the catheter scope secondary to intraarticular adhesions or excessive bleeding. A comparison of the two systems revealed an overall underestimation and underrecognition of intraarticular knee pathologic changes. Anterior cruciate ligament tears were missed in 3 of 21 knees; no posterior cruciate ligament tears were detected by the rod-lens arthroscope in 44 knees, but one false-positive result was "seen" using the optical catheter device. Similar trends in diagnosis (sensitivity, 25% to 67%; specificity, 96% to 99%) were seen for tears of the medial and lateral menisci, chondral lesions, and the identification of loose bodies. We conclude from the results of this study that the use of the optical catheter system for arthroscopic evaluation and treatment of the knee in the office setting may result in a significant compromise in visual acuity, resulting in missed and incorrect diagnoses.

Comparison of efficacy of arthroscopic lavage plus administration of corticosteroids, arthroscopic lavage plus administration of placebo, and joint aspiration plus administration of corticosteroids in arthritis of the knee: A randomized controlled trial.

OBJECTIVE: To compare the efficacy of arthroscopic lavage plus administration of corticosteroids (ALC), arthroscopic lavage plus administration of placebo (ALP), and joint aspiration plus administration of corticosteroids (JAC) in knee arthritis, and to evaluate whether clinical or histologic characteristics determine outcome. METHODS: Patients with knee arthritis (not due to gout, osteoarthritis, or septic arthritis) were randomized over 3 treatment arms: ALC, ALP, and JAC. The primary end point was event-free survival, with events defined as 1) recurrence or persistence of symptomatic knee swelling necessitating local re-treatment, or 2) nonimprovement of the knee joint score. Synovial tissue specimens were collected and analyzed histologically to identify predictive factors of responsiveness. RESULTS: A total of 78 patients were enrolled; 3 patients did not receive their allocated therapy and 3 were lost to followup. The median time until recurrence was 9.6 months after ALC, 3.0 months after JAC, and 1.0 month after ALP, corresponding to a relative risk (RR) of arthritis recurrence of 2.2 for JAC (95% confidence interval [95% CI] 1.2-4.2, P = 0.02) and 4.7 for ALP (95% CI 2.3-9.4, P < 0.0001) compared with ALC. A high versus low synovial extent of fibrosis conferred an RR for recurrence of 5.7 (95% CI 1.6-20.5, P < 0.01) after ALC. CONCLUSION: Arthroscopic lavage plus administration of corticosteroids was more effective than arthroscopic lavage plus administration of placebo or joint aspiration plus injection of corticosteroids. The absence of fibrosis was a histologic predictor of a beneficial response.

[Arthro-C-scan analysis of rotator cuff tears healing after arthroscopic repair: analysis of predictive factors in a consecutive series of 167 arthroscopic repairs].

PURPOSE OF THE STUDY: Arthroscopic repair of rotator cuff tears is a well described technique with good clinical results. The purpose of this work was to use the arthro-CT-scan to evaluate tendon healing after arthroscopic repair and search for epidemiological, anatomic and technical factors predictive of tendon healing. MATERIAL AND METHOD: This prospective consecutive series included 167 non-randomized shoulders. All patients underwent a preoperative assessment using the crude Constant score and a standard x-ray protocol to evaluate cuff status. Cuff repairs were all performed arthroscopically. The crude Constant score was used to follow patients. A control arthroscan was obtained in 148 patients. RESULTS: Mean patient age was 59 years, 46% men and 77% dominant side. Mean duration of symptoms before repair was nine months. The tears resulted from trauma in 28%, including 9% occupational accidents. The preoperative mean crude Constant score was 52.4 (range 15-77). An isolated tear of the supraspinatus was observed in 68%. Frontal retraction of the supraspinatus was distal in 74%. In 29 cases, reduction was difficult. The quality of the tendon was considered normal in 56 cases and non-anatomic repair was necessary in six. At last follow-up (19 months on average) the mean crude Constant score was 80 (range 49-95). Arthro-CT-scan was performed to control healing in 148 patients and revealed anatomic healing in 69, defective healing in 27, and repeated tears in 52 shoulders. Factors predictive of healing were: tear less than six months old, sedentary occupational activity, non-dominant side, young patient, female gender, isolated small non-retracted tear of the supraspinatus, normal appearance of an easily reduced tendon, and good bone quality. DISCUSSION: Time from tear to repair was long in this series. Tendon and muscle changes occurring after the injury could explain in part the healing failures. CONCLUSION: But this study confirmed good functional and anatomic results given by arthroscopic repair of rotator cuff tears.

Prospective comparison of arthroscopic medial meniscal repair technique: inside-out suture versus entirely arthroscopic arrows.

BACKGROUND: Medial meniscal repairs are commonly performed with inside-out sutures and entirely arthroscopic with arrows, but few comparative evaluations on failures have been performed. HYPOTHESIS: No differences in failure rates exist between medial meniscal repairs performed with inside-out suture or entirely arthroscopic at the time of anterior cruciate ligament reconstruction. STUDY DESIGN: Prospective cohort study. MATERIALS: A single surgeon performed 47 consecutive inside-out suture repairs from August 1991 to June 1996 and 98 consecutive entirely arthroscopic repairs with arrows from June 1996 to December 1999. All data were derived from a prospective database and rehabilitation was held constant (nonweightbearing 5 weeks). Clinical success was defined as no reoperation for failed medial meniscal repair. Statistical evaluation was by Kaplan-Meier curves and Cox proportional hazards model. RESULTS: The inside-out suture group had 85% follow-up (40 of 47) with a median 68 months and the entirely arthroscopic group had 87% follow-up (85 of 98) with a median 27 months. There were seven failures in each group. Both Kaplan-Meier curves and the Cox proportional hazards model showed no difference in time to reoperation between techniques (P = 0.85). Three-year success rates (proportions with no reoperations) were 88% for sutures versus 89% for arrows. CONCLUSIONS: Repairs of the longitudinal posterior horn of the medial meniscus during an anterior cruciate ligament reconstruction with nonweightbearing for 5 weeks can be performed with an equivalent high degree of clinical success for both repair techniques.
