Mucoid degeneration of the anterior cruciate ligament.

Mucoid degeneration of the anterior cruciate ligament (ACL) is a rare cause of knee pain. We report a case of a patient with mucoid degeneration of the ACL, presenting with posterior knee pain and no history of a major knee trauma. On clinical examination, the active range of motion showed a flexion deficit.

Knee mobility in femoral lengthening using Ilizarov's method.

Muscle contracture and joint stiffness are a major concern during limb lengthening using the Ilizarov method. The aim of this study was to detect factors that may influence the final loss of knee flexion. We retrospectively studied knee movement in 32 patients undergoing femoral lengthening using the Ilizarov method.
