Thirty-four patients (37 knees) were treated with the Interax knee arthroplasty. There were 31 female and 3 male patients with a mean age at surgery of 70 years (range, 53-84 years). Premature failure of the polyethylene tibial bearing surface occurred in 9 patients (9 knees). Eight patients of these required a revision operation because of early wearing(More)
We report a rare case of angioleiomyoma that occurred in the intra-articular portion of the knee joint. A 43-year-old female was referred to us with a 3-year history of recurrent pain and a loss of full extension of the right knee. Physical examinations revealed swelling and restriction of active full extension. Magnetic resonance imaging (MRI) revealed an(More)
Synovial hemangioma is a rare intra-articular benign tumor that is difficult to diagnose because of its nonspecific symptoms. Patients are generally children or young adults with a nontraumatic recurrent swollen painful knee. A 24-year-old woman presented with a 20-year history of recurrent pain and swelling in the right knee. Physical examination revealed(More)
A case of tenosynovial osteochondromatosis in the tarsal tunnel in a 23-year-old man is presented. The lesion was treated surgically, and multiple osteochondromas were excised, which had no continuity with any tarsal bone or joint cavity but did with the sheaths of the flexor digitorum longus and flexor hallucis longus. Histologic examination of the lesion(More)
BACKGROUND Unsatisfactory long-term results have been reported after use of a Broström repair for patients with chronic ankle ligament insufficiency. HYPOTHESIS Repair or reconstruction of both the anterior talofibular and calcaneofibular ligaments is essential for normal kinematics of the ankle-hindfoot. STUDY DESIGN Case series. METHODS Thirteen(More)
BACKGROUND Prolonged lateral instability of the ankle after ligament injury has been believed to be a major cause of osteoarthritis of the ankle, yet the rate of development of osteoarthritis of the ankle is relatively low. Clarifying the relationship between patient factors and chondral damage of the ankle with prolonged instability is essential to(More)
The purpose of our study is to evaluate whether the hamstring tendons can regrow after harvesting for anterior cruciate ligament (ACL) reconstruction and whether the regenerate tissue can be histologically characterized as tendinous. Eleven of the patients (eight female and three male; mean age, 23 years; range 17–37 years) consented to participate in this(More)
We report a rare case of glomus tumor that occurred in the lateral joint of the knee. A 54‐year‐old man was referred to us with a 3‐year history of lateral pain in the left knee and the diagnosis of lateral meniscus injury. Physical examination revealed a small trigger point localized just on the lateral joint space. Magnetic resonance imaging (MRI) showed(More)
