The importance of arthroscopy in diagnosing synovial haemangioma of the knee joint.

In connection with one of their cases, authors call attention to the importance of differential diagnosis in synovial haemangioma of the knee joint, a rare condition. They also give a survey of its clinical, radiological and pathological features, review the literature on the topic, with special emphasis on the importance of arthroscopy in making the clinical diagnosis, and describe the treatment applied in their case.

Functional improvement after knee arthroplasty without resurfacing of patella.

There has been no universal agreement so far regarding the necessity of patellar resurfacing in total knee arthroplasty. As resurfacing has been reported to be associated with high incidence of complications, this practice has been avoided in our Department. A report is given on the analysis of the functional outcome of 60 knee arthroplasties without patellar resurfacing in 53 patients (7 bilateral) followed up for twelve to thirty months, with special regard to the functions closely related to patelloformal articulation. The underlying diagnosis was osteoarthritis in 78.3%, rheumatoid arthritis in 13.3%, and posttraumatic arthritis in 8.3% of the patients. Graded according to the modified knee-rating system of the Hospital for Special Surgery, excellent or good results were obtained in the case of 55 knees (91.6%) and the mean score improved from 53.6 points preoperatively to 82.6 points following arthroplasty. Subjective and objective functional assessment of stair climbing and transfer activities have shown no functional deficit attributed to the patellofemoral joint of the replaced knee.

The pathological plica in the knee.

Fourteen patients were evaluated who had an arthroscopic removal of the symptomatic mediopatellar plica of the knee in this retrospective study. The main complaint of the patients was the pain at the medial side of the knee. Before the operation only in 3 cases was the diagnosis the pathological plica. The arthroscopy was performed in a routine way. The plica was consider pathological, and removed, when it was thickened. There was grade I or II chondropathy in the knee on the medial femoral condyle and the patella respectively, caused by the plica. Good to excellent result were obtained in 93% of the knee with or without chondromalacia.

Acute arthroscopy.

The role and significance of acute arthroscopy have been evaluated in the treatment of knee joint injuries on the basis of findings during 59 arthroscopic operations which were conducted within two weeks after the accident. The injuries developed isolated in more than half of the cases (65%) whereas they appeared in a combination of two or more in 26% and in 9%, respectively. Injuries requiring operation were found in 91.5%, most of which were ruptures of the ACL (33 cases) and menisci (23 cases). In the case of ACL rupture, in the acute phase on sportsmen and physical workers primary arthroscopically assisted transligamental replacement was performed with patellar graft while in the case of proximal rupture of the ACL reinsertion and augmentation were carried out with semitendinosus tendon. The ruptures of dislocated eminentia were refixed in each case. In the case of the rupture of meniscus the refixation of the meniscus of resection of the ruptured part was attempted. By means of acute arthroscopy the lesion of the intraarticular structures or that of their combinations can be exactly diagnosed. Depending on the findings of arthroscopy the injuries can be treated immediately or operated on at a later time, thus preventing the joint from further deterioration.

Therapeutic value of continuous passive motion after anterior cruciate replacement.

The aim of this study is the evaluation of the therapeutic value of continuous passive motion after ACL replacement. After 41 ACL reconstruction in 13 cases only active motion, in 28 cases active motion and CPM were used postoperatively. Stability, the range of motion and complications were evaluated at the time of discharge, 3 and 6 months after the operation. The flexion-extension in the CPM group was significantly greater at the time of discharge, but this difference was practically eliminated in 6 months after the operation. There were not any other significant difference between the two groups. The CPM gives only a little advantage in the rehabilitation after the ACL replacement.

Managing sacral pressure ulcers with hydrocolloid dressings: results of a controlled, clinical study.

One-hundred and three patients with Stage II and III sacral pressure ulcers were enrolled in a prospective, controlled, multi-center clinical study to evaluate and compare dressing performance, safety and efficacy. Fifty-two patients were randomized to treatment with a triangle-shaped hydrocolloid border dressing and 51 patients were randomized to a different, oval shape, hydrocolloid dressing. The majority of patients (70 percent) utilized a pressure reducing mattress or bed. Most ulcers were Stage II, had existed for < 1 month and exhibited no change utilizing previous treatments. Patients and wounds were similarly distributed among treatment groups. Patients in the oval dressing group were more likely to exhibit a product related adverse reaction resulting in discontinuation of treatment as compared to patients treated with the triangle border dressing (p = 0.057, Fisher's Exact Test). Wear time was longest for wounds dressed with the triangle dressing applied point down. Incontinence reduced the interval between dressing changes in both groups. Healing was more likely to occur in wounds dressed with the triangle border dressing. These ulcers showed a greater reduction in ulcer width as compared to wounds dressed with the oval dressing (p < 0.03, Fisher's Exact Test).

[The KT 1000 arhtrometer in the comparative study of stability of knee joints operated on for instability].

In 1981 through 1989 authors performed 160 complex reconstruction operations for instability of the knee joint according to the basic principles of W. Müller, striving to restore all structures injured. 92 patients with 378 operations were controlled. The assessment of the results was based on the physical examination, the measurement of ligament laxity with the K 1000 arthrometer, the opinion of the patients, the level of their activity and Lysholm's functional point system was used. The stability of the knee could be restored in 73 per cent of the cases. The patients have thought the knees, found more stable with the arthrometer, really more stable. There was however no unambiguous relation between the knee stability and the level of activity of the patients. The most frequent complaint was pain, increased synovial fluid and the hindrance of squatting. The results were better if the patient had no previous operation in an other department and in those who did not need menisectomy, who had less operations, less body weight and better muscular force.

[Measuring the looseness of the knee joint by using the Kt 1000 arthrometer].

Authors measured the stability in the sagittal plane of the intact knee joints of 50 young men with the MEDmetric KT 1000 apparatus. The greatest movement during the measurements on 100 knees was observed in 25 degrees flexion and during the application of force 89N. In 70 degrees flexion the movement was only half of that observed in 25 degrees flexion. The difference of the average movements measured bilaterally was neither in active nor in passive experiments more than 0.5 mm. The difference between the average values of the compliance indexes on the left and right side was only 0.01 mm. In all measurements the frequency distribution of the differences between the two sides was essentially the same. The difference between the movements on the two sides did not exceed 2 mm-s in 90-100 percent of the cases.
