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;
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, whereas MRI showed a well-circumscribed lesion. A local excisional biopsy was performed and microscopic appearance confirmed diagnosis.
Three hundred and eighty-four athletes with chronic anterior cruciate instability were treated by a free autologous graft of the lateral third of the patellar tendon. Evaluation 5 to 9 years after operation was carried out in 334 cases by physical examination, the KT-1000 arthrometer and the Tegner and Lysholm scoring scale. There were 89.5% satisfactory results and 10.5% were unsatisfactory. Global instability, advanced osteoarthritis and restricted movement after operation were the reasons for a poor outcome. In 9 cases, histological examination showed good incorporation of the graft.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
