[Total knee replacement after valgus tibial osteotomy. Technical problems].

Forty total knee replacements following valgus tibial osteotomy were analysed. There were 38 patients (10 men and 28 women) with a mean age of 72 years at the time of the joint replacement, at a mean of 8.5 years after osteotomy. Mean follow-up was 3 years (1 to 5 years). Performing a total knee replacement after valgus tibial osteotomy posed some specific problems due to asymmetrical bone cuts, residual ligament laxity, loss of bone at the tibial plateau, and especially when there was a malunion of the previous osteotomy. The functional results were good. A group of 208 patients with total knee replacements for untreated osteoarthritis acted as a control for comparison. In the group with an osteotomy the results were worse in respect of the walking distance and flexion angle achieved after joint replacement compared with primary replacement (p < 0.001). However the GUEPAR and HSS score 77.2 +/- 2.3 were very similar. Using unilateral weight-bearing X-rays, 18.8p. 100 demonstrated opening from ligament laxity and 40.6p. 100 had radiolucent lines under the components, which was the same as in the control group. The tibio-femoral mechanical axis using long-leg films had a mean varus angle of 0.7 degrees.

[Osteoid osteoma of the foot. Apropos of 4 personal cases].

On the basis of four personal cases of osteoid osteomas of the foot, the authors study their frequency, their localization, and their clinical and radiological manifestations. They insist on the special difficulties of diagnosing this condition due to its atypical and uncertain radiological outline, and also on methods of further investigation : arteriography and especially isotopic scintigraphy.

Controlled trial of platelet anti-aggregating agents and subcutaneous heparin in prevention of postoperative deep vein thrombosis in high risk patients.

In a prospective randomised trial, three groups of 20 patients each were compared. A first group served as a control, a second group received dipyridamole and acetylsalicylic acid and a third group received low doses of heparin. The incidence of deep vein thrombosis determined by the 125I-fibrinogen test was 40% in the first group, 50% in the second group, and 5% in the third group. The differences between the heparin group and the two other groups are statistically significant. No wound complication and no haematoma at the injection site occurred.

[Unicondylar fractures of the femur].

The authors have treated and reviewed 8 recent and 24 ancient unicondylar fractures of the femur. They point out that initial diagnosis had often been missed, due to associated lesions or apparently minimal displacement. They think that recent fractures should always be surgically treated by sagittal screwing. Indications are given for the treatment of malunions (osteotomies, arthrolysis, arthrodesis, prosthesis).

[Treatment problems in old and recent rupture of the lateral knee ligament].

The authors have treated 31 fresh ruptures of the lateral ligament and 104 cases of chronic instability of the lateral side of the knee. In recent ruptures the results obtained after surgical repair were not as gratifying as those obtained after injuries of the medial ligament. The cases operated upon were tears of the lateral ligament associated with ruptures of one or both cruciate ligaments. The frequency of rupture of the popliteus tendon is emphasized. The authors recommend, when necessary, a double surgical approach both laterally and posteriorly and plaster cast immobilization for more than 6 weeks. Tendon transfer in recent lesions have been done when suture of a cruciate ligament was impossible. The results of several procedures for chronic instability were analysed; transposition of the patellar ligament, transposition of the head of the fibula, or tightening of the lateral structures of the knee (capsule, ligament, popliteus tendon). Associated lesions of the cruciate ligament were treated by tendon transfer. Poor results were obtained in those presenting with fixed varus deformities. The authors conclude that such deformities should be corrected by osteotomy.
