Relationship between ultrastructure and biomechanical properties of the knee meniscus.

The purpose of this study was to determine the biomechanical properties of the knee meniscus and to relate them to its ultrastructure. The knee joint menisci are semicircular, fibrocartilaginous structures interposed between the femoral and tibial condyles. For a long time, they were considered to be embryologic vestiges.

Arthrodesis of the first metatarsophalangeal joint using convex and concave drills. A report on 50 cases.

The authors report their results after arthrodesis of the first metatarsophalangeal joint (MP) performed in 50 cases including 18 rheumatoid feet, 18 major hallux valgus deformities and 14 recurrent deformities. Preparation of the bone ends for arthrodesis was achieved using convex and concave drills and fixation was done with an axial screw. The patients were evaluated after an average of 12 months, using Kitaoka's score.

[Surgical treatment of chronic Achilles tendiopathies. Report of 52 cases].

Purpose Of The Study: We reviewed a series of 52 cases of chronic Achilles tendinopathy treated surgically by release of the fascia cruris, resection of peritendon, longitudinal incision of the tendon and occasional excision of intratendinous lesions.

Materials And Methods: The mean course prior to surgery was about 18 months. Twenty-six patients practiced sports.
