Partial or total open meniscectomy? A prospective, randomized study.

In order to compare partial with total meniscectomy a prospective clinical study of 200 patients was carried out. At arthrotomy 100 patients were allocated to each type of operation. The two groups did not differ in duration of symptoms, age distribution, or sex ratio. The operations were performed as conventional arthrotomies. One hundred and ninety two of the patients were seen at follow up 2 and 12 months after operation. There was no difference in the period off work between the two groups. One year after operation, 6 of the 98 patients treated with partial meniscectomy had undergone further operation. In all posterior tears were found at both procedures. Among the 94 patients undergoing total meniscectomy, 4 required further operation. In each, part of the posterior horn had been left at the primary procedure. One year after operation significantly more patients who had undergone partial meniscectomy had been relieved of symptoms. However, the two groups did not show any difference in the degree of radiological changes present.

Sports injuries of the knee ligaments--a prospective stress radiographic study.

Forty-six patients were entered into a prospective clinical and stress radiographic study done to assess the value of acute surgical treatment of injuries to the knee ligaments sustained during sports activities. After an average follow-up period of 5 1/2 years (range 4-6 1/2 years) medial instability was found only in two patients, both of whom were in the group with isolated rupture of the medial collateral ligament. Nine of the 29 patients in this group developed rotatory instability, but it was moderate and did not give rise to symptoms. Among the 17 patients with either injuries to the anterior cruciate ligament or combined injuries, anterior drawer instability persisted in seven, with an insufficient functional result in five. None of these 17 patients were able to resume competitive sport. Those patients who had not exercised physically just before the injury proved to have a significantly greater total instability than those who had. Therefore, routine limbering-up is recommended before sports activities.

Prospective stress radiography in 38 old injuries of the ligaments of the knee joint.

In a prospective clinical and stress radiographic study comprising 38 patients, the course of chronic ligament injuries in the knee joint was evaluated. All but five patients had isolated ligament injuries, 16 of which affected the anterior cruciate ligament. The operations were performed from 18 days to 20 years after the injury had occurred. In 13 patients primary suture could be carried out, 12 patients underwent exploratory arthrotomy, and the remainder had relevant ligament repair. After a follow-up period of 7 years the instability had been cured in all patients with medial laxity and in one of two patients with lateral laxity. Nineteen patients had a drawer sign preoperatively. The anterior drawer sign disappeared in practically all patients, while a posterior drawer sign was a constant sequel to injury affecting the posterior cruciate ligament. It was difficult to prevent the development of rotatory instability--which was present in six preoperatively and in 14 at follow-up--and the rotatory instabilities were predominantly marked (greater than 6 mm). Nevertheless, only a few patients had an annoying sensation of instability. By means of ligament reconstruction, it was possible to reduce the preoperative instability appreciably. Passive instability had completely subsided in 40 per cent (15/38). The subjective result was good, only 16 per cent (6/38) having troublesome loss of function.

Prospective stress radiographic study of knee ligament injuries in 62 patients treated by acute repair.

A prospective clinical and stress radiographic study comprising 62 patients was performed to assess the value of acute repair of 35 isolated collateral ligament injuries and 27 major injuries. After a follow-up period of 6 years there was no lateral or medical instability in 42 out of 46 patients. This included 31 out of 33 patients in the group with medial collateral ligament injuries. Among the patients with major injuries 16 (60 per cent) had drawer signs, but in only 6 was there significant instability (greater than 6 mm). In the total material it proved difficult to prevent the development of rotatory instability. This was present in 10 patients preoperatively and in 19 at follow-up. However, this instability was on the whole slight and was experienced as annoying by only 4 patients. Measurement of passive instability showed that 55 per cent (34/62) had become completely stable, but this applied to only 30 per cent (8/27) of patients with major injuries. The functional end result was unsatisfactory in 8 patients (13 per cent). Although several patients could compensate muscularly for a marked passive instability, there was a significant correlation between instability and functional loss.

A solitary malignant schwannoma mimicking a pancreatic pseudocyst. A case report.

A case is presented in which a cystic process occupying the body and tail of the pancreas peroperatively was regarded as a pancreatic pseudocyst but post-operatively showed a microscopic picture of cystic malignant schwannoma. It is concluded that in case of a presumed pancreatic pseudocyst, peroperative microscopy--when possible--of frozen sections of the cyst wall before performing a drainage operation is indicated.

Pes anserinus and iliotibial band transfer for anterior cruciate insufficiency.

Twenty-one patients with chronic anterior cruciate ligament insufficiency were treated with a combined iliotibial band (Ellison) and pes anserinus (Slocum-Larson) transfer procedure. Preoperatively, the most prominent instabilities were drawer laxity in 16 patients and anteromedial rotation in 5 patients. After a median of 34 months of followup, 15 patients were absolutely satisfied with the result, 2 were fairly satisfied, and 4 were not satisfied at all, including 2 patients who had been reoperated. All of the patients with unsatifactory results had a pivot shift and a positive Slocum test. Intraarticular derangements had no influence on the results. At followup, 14 patients demonstrated an anteromedial rotatory instability, indicating that the lateral stabilization procedure acted better than the medial one. Only a few patients returned to their preinjury levels of sports activity. Compared with other extraarticular procedures in the literature, the results were quite similar. The operative procedures used in this study cannot be recommended in cases with combined instabilities of the knee.

The course of differently treated isolated ruptures of the anterior cruciate ligament as observed by prospective stress radiography.

In a prospective stress radiographic study of the course of 21 isolated anterior cruciate ligament (ACL) injuries, primary suture was performed in eight patients and reconstruction due to chronic instability was performed in six patients. Seven patients were treated by exploratory arthrotomy only. After a follow-up period of seven years the anterior drawer sign had disappeared in five of the 14 patients who had shown this sign prior to operation, but in some of these patients progressive rotatory instabilities developed, so that the total abnormal instability did not improve in any of the three therapeutic groups. Only ten patients obtained a completely symptom-free knee. A well performed Jones procedure could reduce a chronic anterior drawer instability, but in several of the patients troublesome patellofemoral pain developed later. Acute suture of isolated anterior cruciate ligament injuries afforded the best results in this series and is recommended.
