A comparative study of the diagnostic accuracy between the Lachman test and the anterior drawer test was performed by examining 144 knees with ruptured anterior cruciate ligaments. The diagnosis of anterior cruciate ligament rupture is often difficult to establish, especially in recent injuries with acute haemarthrosis. The diagnostic accuracy of the(More)
We used the MacIntosh over-the-top repair combined with a popliteal tendon plasty in 273 athletically active patients with chronic incapacitating functional instability due to anterior cruciate ligament rupture; 244 were reviewed at three to nine years after operation. We describe the technique and its results, with functional evaluation by the Tegner and(More)
Though osteoid osteoma is a common primary benign lesion of the bones, intra-articular involvement is rare and poses diagnostic difficulties when it affects middle-aged patients. We present the case of a 51-year-old woman with a 2.5 year history of anterior knee pain that was misdiagnosed as osteochondritis dissecans. Radiological findings were absent,(More)
The purpose of this study was to demonstrate the extent of meniscal involvement when the anterior cruciate ligament is torn. Data from 189 cases operated on for lesions of the anterior cruciate ligament form the basis of this report. The patients chosen for this study were all athletes forming two main groups. In one group, 82 patients were operated on(More)
Bone lesions are present in 1% to 2% of cases of hydatid disease. Hydatid synovitis can usually be identified due to secondary extension from the adjacent bone, or infrequently after hematogenous spread. We present an extremely rare case of hydatid synovitis without bony involvement. A 74-year-old man with diagnosed hydatid disease was admitted to our(More)
In 30 rabbits, the medial meniscus was used to replace the anterior or posterior cruciate ligament. The changes that took place were followed in histological sections, obtained both from the area of insertion into bone and from the intra-articular part of the graft. There was a gradual differentiation to chondroid tissue, with subsequent calcific deposition(More)
