Total hip arthroplasty in patients 50 years and younger.

Because the young patient with a total hip arthroplasty is presumed to place increased demands on a reconstruction for a longer period than the average patient with a hip replacement, long-term results are expected to be inferior. To determine the efficacy of total hip replacements in this population, the current authors reviewed the long-term results of patients who were 50 years and younger who had cementless total hip arthroplasties at their institution, and reviewed the literature on total hip arthroplasty in younger patients. The results from the study population and the literature were encouraging. At the author's institute, during the past 20 years, 561 hip replacements were done on 488 patients in this age group, using extensively porous-coated cobalt-chromium stems matched with beaded, press-fit acetabular components of cobalt-chrome or titanium. Using the Kaplan-Meier technique, the survival rates for femoral and acetabular components, using any revision as an end point, were 89% at 10-year followup and 60% at 15-year followup. A subset of the authors' patients who were 40 years and younger (256 hips, 223 patients) had slightly inferior results, with 85% 10-year survivorship and 54% 15-year survivorship, using any revision as an end point. A comprehensive literature review also showed that long-term success can be achieved with cemented or cementless total hip arthroplasties in young patients. Because some reconstructions exhibited inferior results in younger patients, the authors recommend that surgeons be much more critical of the components used in these patients and allow long-term data to guide their decisions.

Establishing a home care protocol for early discharge of patients with hip and knee arthroplasties.

Joint arthroplasty procedures are significant in number and cost. Discharging hip and knee arthroplasty patients early from the hospital to a transitional home care program has the potential to reduce costs, while maintaining quality. A retrospective review of hospital records of hip and knee arthroplasty patients quantified patient problems during postoperative days 3 through 12 and analyzed them by age, gender, and joint type. The pilot study also allowed the development of a protocol for transitional home care after hip and knee arthroplasty.

Total hip arthroplasty for complications of proximal femoral fractures.

OBJECTIVES: To determine problems associated with and to present the results of secondary total hip replacement for complications of proximal femoral fractures. SETTING: An acute care hospital with a prospectively entered database for primary total hip arthroplasty. PATIENTS AND PARTICIPANTS: The prospective database was reviewed to extract all patients undergoing primary total hip replacement for complications of treatment of proximal femoral fractures. These fifty-three patients were then compared with fifty-three patients from the same data bank matched for age, sex, weight, prosthesis type, and length of follow-up but who had not sustained a proximal femoral fracture before total hip replacement. INTERVENTION: Primary total hip arthroplasty for complications of proximal femoral fractures. After the surgical procedure, patients were seen at follow-up intervals of three months and six months and, thereafter, yearly. MAIN OUTCOME MEASUREMENTS: Patients were evaluated using the St. Michael's hip rating scale, which is a scale measuring pain, motion, and function specifically designed for evaluation of total hip arthroplasty. Routine radiographs were obtained at each patient visit. RESULTS: The complications associated with total hip replacement in patients with previous proximal femoral fracture fixation occurred more frequently than in patients who had not had undergone previous fracture fixation; in addition, intraoperative surgical difficulty was significantly greater in those patients who had undergone previous surgery for hip fracture. However, the final hip score at > or = 2 years after total hip arthroplasty was not statistically different between the two patient groups. CONCLUSION: Total hip replacement is a satisfactory salvage procedure for failed fracture treatment despite the increased incidence of operative difficulty and increased incidence of complication.

Management of the recalcitrant total-hip arthroplasty wound.

The infection rate for total-hip arthroplasty is around 1 percent. This small group is usually managed by complete removal of the prosthesis and the cement and closure over suction catheters to "collapse" the wound and eventually achieve a girdlestone arthroplasty. Occasionally, there are patients who have a persistent draining wound after this treatment and repeated efforts at wound closure. We present 27 patients who had recalcitrant, noncollapsible wounds of the hip that were present for many months to years. Twenty-eight cases of infected total-hip arthroplasties that did not respond to removal of the prosthesis and cement and closure were seen by the authors between January of 1977 and December of 1988. One patient had bilateral involvement. Average age was 64 years (range 33 to 79 years). There was an average of 4.2 previous surgical attempts at closure (range 1 to 21). Staphylococcus aureus was the most common organism, but the infections were virtually all multiple. Thirty-three muscles were utilized in 27 patients. The rectus femoris was used in 23 cases, the vastus lateralis in 8, tensor fasciae latae in 1, and combined latissimus dorsi-serratus anterior free-tissue transfers were carried out in 2. Multiple combinations of transpositions and free flaps were utilized. Follow-up ranged from 1 to 10 years, with an average of 6.4 years. Eighteen patients were ambulatory with minor degrees of pain, five ambulated with a cane, seven ambulated with a walker, six ambulated with crutches, and four ambulated unassisted, all of whom had reimplantation of their hip arthroplasty at least 12 months following the muscle flap procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

Medial gastrocnemius flap coverage for treatment of skin necrosis after total knee arthroplasty.

UNLABELLED: Skin necrosis after total knee arthroplasty is a rare complication that can rapidly lead to deep infection of the prosthetic components. The medial gastrocnemius transposition flap usually provides adequate soft tissue coverage to salvage the total knee arthroplasty. However, variations in defect location and excursion of the muscle flap can affect results. Twelve patients were treated with a medial gastrocnemius transposition flap after total knee arthroplasty. The skin defect that required flap coverage was located over the tibial tubercle or patellar tendon in eight patients (Group 1). The defect extended proximally to the patella or quadriceps tendon in four patients (Group 2). A functioning total knee arthroplasty was salvaged in 11 patients (92%). The medial gastrocnemius flap healed primarily in all patients in Group 1. Three patients in Group 2 required additional fasciocutaneous, lateral gastrocnemius, or free flap coverage, and one patient underwent above knee amputation. The medial gastrocnemius flap is most effective for coverage of distal defects over the tibial tubercle or patellar tendon. Defects that extend more proximally over the patella or quadriceps tendon are more likely to require additional procedures to achieve adequate soft tissue coverage.

Implications for rehabilitation after total wrist arthroplasty.

Achieving satisfactory, long-term functional outcomes after total wrist arthroplasty surgery has proved more complicated than with arthroplasties in joints such as the hip or knee. However, improvements in implant design and surgical technique have resulted in recent successes and evidence that wrist arthroplasty may be an appropriate choice to improve function in select patients. This article reviews factors that therapists must consider in planning, implementing, and progressing individual patients' rehabilitation programs after wrist arthroplasty surgery. Therapists must be knowledgeable about the specifics of each patient's surgery so that the rehabilitation program can be customized appropriately and can contribute to achieving pain-free stable wrist movement that allows patients to perform their desired functional activities.

MacIntosh arthroplasty for the rheumatoid knee: a 10-year follow up.

The results of 75 MacIntosh arthroplasties performed for rheumatoid arthritis of the knee in 63 patients were reviewed at least 10 years after surgery. Forty-two knees in 35 patients were available for assessment. Eleven arthroplasties had been revised to total knee replacement without difficulty because of pain or poor function. The remaining 31 knees in 25 patients gave good or excellent results in 22 cases, fair in eight, and poor in one. Seven patients could not be traced, and 21 patients representing 26 knees had died. At least half these knees had given satisfactory results immediately before death judged by review of the case notes. The difficulty of comparing functional status with the preoperative state because of progressive multiarticular disease was highlighted. Although greater angular deformities preoperatively reduced the chance of success in the medium term, late failure of the arthroplasty after five years was very rare. Approximately two-thirds of all the arthroplasties performed gave satisfactory results at 10-year follow up or until the time of death.

From the RSNA refresher courses. Total hip arthroplasty: radiographic evaluation.

Expected appearances of total hip arthroplasty vary according to type of implant, its method of fixation (cemented, porous coating for bone ingrowth, press fit), and whether it is a revision. Cemented arthroplastic components normally may show 1-2-mm-wide radiolucent zones at cement interfaces. Definite loosening is diagnosed when progressive widening of the radiolucent zone, migration of a cemented component, or change in alignment is seen. In cementless arthroplasty, normal findings include calcar resorption, radiolucent zones up to 2 mm in width, cortical thickening, periosteal reaction, endosteal sclerosis, and even subsidence of the femoral component that stabilizes at less than 1 cm. The most reliable radiographic signs of loosening in cementless arthroplasty are progressive subsidence, migration, or tilt of the component. Because subsidence or change in alignment may be very subtle, serial radiography and measurement are often required for diagnosis. Other signs that indicate loosening include bead shedding (in porous-coated prostheses), extensive cortical hypertrophy, endosteal bone bridging at the stem tip, endosteal scalloping, and a radiolucent zone wider than 2 mm. In revision arthroplasty, wide radiolucent zones and subsidence are common. The diagnosis of revision failure is based on progressive widening of the radiolucent zones and change in component position after 12 months.

Hip arthroplasty: the role of plain radiographs in outpatient management.

PURPOSE: To determine whether findings on plain radiographs alter clinical care in outpatient management after hip arthroplasty. MATERIALS AND METHODS: From June 1, 1993, through February 28, 1994, one arthroplasty surgeon saw 148 outpatients (age range, 15-86 years) after hip arthroplasty (163 prostheses). The surgeon made decisions about clinical management before he reviewed the plain hip radiographs. After he reviewed the radiographs, he recorded any changes in the management plan. RESULTS: In only one case did the radiographic findings change patient treatment. The prosthesis in this relatively asymptomatic patient had been in place for over 9 years and appeared clinically to be functioning well, but radiographs demonstrated aggressive granulomatosis. Therefore, the patient underwent revision arthroplasty. In the remaining 147 patients, radiographic findings had no impact on clinical management. CONCLUSION: Radiographic evaluation may be most beneficial in patients with hip prostheses that have been in place for many years to rule out asymptomatic bone loss due to aggressive granulomatosis.

Ceforanide vs. cephalothin concentrations in total joint arthroplasty.

Total joint arthroplasty is a common orthopedic procedure and requires prophylactic antibiotic coverage to prevent infections in the operated joint. The antibiotics routinely used for prophylaxis are the cephalosporins. This study compared bone, synovial fluid, and plasma concentrations of ceforanide with cephalothin concentrations in 30 patients undergoing elective total hip or total knee arthroplasty. Ceforanide provided significantly higher plasma concentrations for 61-110 minutes postdose than did cephalothin (p less than 0.025 and p less than 0.005). No difference was noted between the two antibiotics for the bone concentrations in the total hip arthroplasty group; however, cephalothin concentrated to a greater degree in the bone of patients undergoing total knee arthroplasty (p less than 0.05). Cephalothin achieved higher concentrations in the synovial fluid than did ceforanide (p less than 0.05). Both antibiotics were well tolerated and no postoperative infections were noted in either group.

Periprosthetic fracture of the femur after hip arthroplasty: The clinical outcome using cortical strut allografts.

Between 1993 and 1998, 15 patients with periprosthetic fractures of the femur after hip arthroplasty were treated using deep-frozen cortical strut allografts as an adjunct support after internal fixation or revision arthroplasty. According to the Vancouver classification system, there were 7 type B1, 2 type B2, 4 type B3 and 2 type C fractures. Seven patients had severe osteopenia, 10 patients had bone defects between 2 to 7 cm and 2 were associated with infection. Nine patients had internal fixation of the fracture using a compression plate, and 6 had revision arthroplasty using a long-stemmed femoral prosthesis. The average length of the allograft was 13.9 cm. At an average follow-up of 31 months, all the patients had a satisfactory functional result except one who had a leg length discrepancy of 4 cm due to multiple operations. There were no non-unions, malunions or infections. The fractures healed between 10 to 24 weeks (average, 15.6 weeks). In conclusion, a cortical strut allograft associated with internal fixation can be an effective method of treating periprosthetic fractures of the femur after hip arthroplasty.

Total knee arthroplasty in the patient with Parkinson's disease.

We have reviewed nine patients with Parkinson's disease who had 12 primary total knee arthroplasties and one revision. Deformities were corrected by conventional techniques and semi-constrained resurfacing arthroplasties were used. Follow-up ranged from two to eight years (average 4.3 years). Nine of the 12 primary arthroplasties were rated as excellent by the Hospital for Special Surgery knee score system, and three were rated as good. Contrary to previous reports, we feel that total knee arthroplasty performed on patients with Parkinson's disease, is a highly satisfactory procedure, alleviating knee pain and improving function.

Secondary arthroplasty for complications of femoral neck fracture.

We report a series of 640 consecutive cervical hip fractures which were followed prospectively for two years after primary internal fixation with two hook-pins. Secondary arthroplasties were performed as salvage procedures in 75 cases and the early outcome of these was studied retrospectively. The mean time in hospital was 25 days for prosthetic replacement, though 60% of the patients had other medical conditions considered as risk factors. Mortality was 5% after six months and 8% after one year. Dislocation was seen in 11% and additional surgery was required in 4%. There was one case of deep infection and one supracondylar femoral fracture. In some cases there was considerable delay between the primary and secondary operation due to lack of awareness of functional deterioration, but although many patients had poor mobility before the secondary operation this was greatly improved within six weeks of the arthroplasty. We conclude that elective secondary hip arthroplasty for failure of fracture fixation is a safe and successful procedure. Once the decision to perform an arthroplasty is taken, this should be done without delay to avoid deterioration of function.

De la Caffinière arthroplasty for basal thumb joint osteoarthritis.

We performed 20 de la Caffinière trapeziometacarpal arthroplasties for osteoarthritis occurring only at this joint and reviewed all patients after periods of up to ten years. Eighteen arthroplasties were satisfactory postoperatively, although all 20 patients had a satisfactory range of motion and only one experienced pain after surgery such that it impeded normal function. Failure occurred in two patients and was due to overreaming of the trapezium during surgery and a traumatic dislocation. A radiolucency between the prosthesis and bone was observed in one arthroplasty, although this patient was asymptomatic. We recommend arthroplasty using the de la Caffinière prosthesis as a satisfactory method of treatment for the osteoarthritic trapeziometacarpal joint.

The hospital cost of total hip arthroplasty. A comparison between 1981 and 1990.

The change in the hospital cost of total hip arthroplasty over a ten-year period at the Lahey Clinic was evaluated by comparison of the hospital bills for forty-four hip replacements that had been performed in 1981 with the bills for 104 such operations that had been done in 1990. Each hospital charge was converted to cost with use of government-mandated hospital-specific cost-to-charge ratios. The average actual hospital cost for total hip arthroplasty increased 46.5 per cent, from $8428 in 1981 to $12,348 in 1990. However, in inflation-adjusted dollars, the cost increased only 1.9 per cent. During this period, the cost for a patient room decreased from 50 per cent of the hospital cost in 1981 to 37 per cent of the hospital cost in 1990. In sharp contrast, the cost of hip prostheses increased from 11 per cent of the hospital cost in 1981 to 24 per cent of the hospital cost in 1990. The actual dollar cost of the hip prostheses increased 212 per cent, and the inflation-adjusted dollar cost increased 117 per cent. The hospital cost of total hip arthroplasty during the 1980's was controlled by decreases in the length of stay in the hospital and in the volume of services delivered. The unit costs of supplies and, specifically, the cost of hip prostheses were not controlled. In the 1990's, efforts to control the hospital cost of total hip arthroplasty must concentrate on decreasing the cost of the prostheses and on controlling the unit costs of personnel and of hospital supplies.

The outcome of Charnley total hip arthroplasty with cement after a minimum twenty-year follow-up. The results of one surgeon.

We evaluated the results of 330 total hip arthroplasties that were performed with use of the Charnley prosthesis and cement in 262 patients by the senior one of us between July 1970 and April 1972. All hips had been thoroughly assessed preoperatively to document the patient's functional level. All patients had been disabled because of pain in the hip or a fracture of the hip, and 212 patients (81 per cent) had used walking aids. At a minimum of twenty years after the index operation, eighty-three patients (ninety-eight hips) were still living, 174 patients (224 hips) had died, and five patients (eight hips) had been lost to follow-up. The outcome of the arthroplasty was determined for all except the five latter patients. Thus, the outcome of 322 (98 per cent) of the 330 arthroplasties was known at the latest follow-up evaluation. Radiographs were available for sixty-three of the eighty-three patients (seventy-six [78 per cent] of the ninety-eight hips) who were alive for the entire follow-up period. Of the ninety-eight hips in the living patients, eighty-three (85 per cent) caused no pain, fourteen (14 per cent) caused mild pain, and one (1 per cent) caused moderate pain. Fifty-two hips (53 per cent) were in patients who did not use walking aids, and only seven (7 per cent) were in patients who used support for walking because of the hip. At the minimum twenty-year follow-up, thirty-two (10 per cent) of the 322 hips that had been followed had been revised: eight (2 per cent), because of loosening with infection; twenty-one (7 per cent), because of aseptic loosening; and three (1 per cent), because of dislocation. Of the ninety-eight hips of the patients who were still alive, fifteen (15 per cent) had been revised: three (3 per cent), because of loosening with infection; eleven (11 per cent), because of aseptic loosening; and one (1 per cent), because of dislocation. The rate of revision due to aseptic loosening of the acetabular component in all 322 hips was 6 per cent (eighteen hips), while in the ninety-eight hips of the patients who were alive at least twenty years after the arthroplasty, it was 10 per cent (ten hips). The rate of revision because of aseptic loosening of the femoral component in all 322 hips was 2 per cent (eight hips), while in the ninety-eight hips of the living patients, it was 3 per cent (three hips).(ABSTRACT TRUNCATED AT 400 WORDS)

Humeral fractures after shoulder arthroplasty.

Nine humeral fractures occurred subsequent to 499 shoulder arthroplasties that had been performed between December 1978 and November 1987 at the Mayo Clinic. The time from the arthroplasty to the fracture averaged thirty-nine months (range, eight to 101 months). Seven patients were women and two were men, and the average age was seventy years (range, forty-five to eighty-five years). The arthroplasties were performed for rheumatoid arthritis in five patients and for the sequelae of trauma in four. Six patients had advanced osteopenia, and two had had an ipsilateral total elbow arthroplasty. Six of the fractures were centered at the tip of the prosthesis; one fracture (type A) extended proximally, and five (type B) did not. The three remaining fractures (type C) involved the humeral shaft distal to the implant and extended into the distal humeral metaphysis. Four fractures healed with non-operative treatment. Two fractures that had unacceptable alignment were treated successfully with operative intervention. Three fractures that were treated with immobilization in a splint failed to heal; two of those fractures eventually united after a revision of the prosthesis and bone-grafting was performed, and one fracture remained ununited. Radial nerve palsy developed postoperatively in two patients, and it resolved within three months. Five patients had poor active motion before the fracture, and two of them had even less motion after the fracture was treated. Our experience suggests that long oblique and spiral fractures can be successfully treated non-operatively, provided that the skeletal alignment is acceptable.(ABSTRACT TRUNCATED AT 250 WORDS)

Prophylaxis against deep venous thrombosis after total knee arthroplasty. Pneumatic plantar compression and aspirin compared with aspirin alone.

A prospective, randomized study was conducted to assess the efficacy of pulsatile pneumatic plantar compression for prophylaxis against deep venous thrombosis after total knee arthroplasty performed with use of regional anesthesia. One hundred and twenty-two patients (164 knees) who were scheduled to have a unilateral or a one-stage bilateral total knee arthroplasty were separately randomized to be managed with either aspirin alone or the pulsatile pneumatic plantar-compression device and aspirin. The prevalence of deep venous thrombosis was 27 per cent (twenty-two of eighty-one knees) in the group treated with pneumatic plantar compression compared with 59 per cent (forty-nine of eighty-three knees) in the patients managed with aspirin alone (the control group) (p < 0.001). A significant difference was also noted in the group that had had a unilateral arthroplasty (a prevalence of 27 per cent [eleven of forty-one knees] in the group treated with pneumatic plantar compression, compared with 67 per cent [twenty-six of thirty-nine knees] in that treated with aspirin alone; p < 0.006) and in the group that had had a one-stage bilateral procedure (a prevalence of 28 per cent [eleven of forty knees] in the group treated with pneumatic plantar compression, compared with 52 per cent [twenty-three of forty-four knees] in that treated with aspirin alone; p < 0.03). No proximal thrombi were noted in any patient who used the pulsatile pneumatic plantar-compression device, while the prevalence of proximal thrombosis in the popliteal or femoral veins was 14 per cent (twelve of eighty-three knees) in the group treated with aspirin alone (p < 0.0003). In the group treated with a unilateral procedure and aspirin alone the prevalence of proximal thrombosis was 13 per cent (five of thirty-nine knees; p < 0.02), while in the group treated with a bilateral procedure and aspirin alone it was 16 per cent (seven of forty-four knees; p < 0.01). Only in the patients who had had a unilateral procedure was use of the compression device associated with significantly less edema postoperatively than was use of aspirin alone. The change between the preoperative and postoperative circumferences of the thigh and leg was significantly less (9 +/- 4.1 millimeters [mean and standard deviation] less for the thigh [p < 0.01] and 6 +/- 3.9 millimeters less for the leg [p < 0.049]) with the compression device than with aspirin alone. In addition, there was significantly less mean drainage (98 +/- 61.1 milliliters) in the group treated with a unilateral procedure and pneumatic compression, compared with that treated with a unilateral procedure and aspirin alone (p < 0.041). An internal timer of the compression device was used to assess the compliance of the patient with use of the device, and a relationship between deep venous thrombosis and the total duration of treatment with the device was found. The patients in whom deep venous thrombosis did not develop used the device for a mean of 96 +/- 23.4 hours (range, sixty to 164 hours) postoperatively, or 19.2 +/- 5.1 hours a day, while those in whom thrombosis developed used it for a mean of 67 +/- 21.1 hours (range, twenty-six to 101 hours), or 13.4 +/- 4.3 hours a day (p < 0.001). No untoward effects were noted in any patient who used the device. This study confirms the safety and efficacy of pulsatile pneumatic plantar compression and aspirin compared with aspirin alone and supports the use of mechanical compression for prophylaxis against deep venous thrombosis and for reduction of edema in patients who have had a total knee arthroplasty. In addition, we found a direct relationship between compliance with the use of this device and its efficacy in reducing deep venous thrombosis.
