Posteromedial Meniscocapsular Lesions Increase Tibiofemoral Joint Laxity With Anterior Cruciate Ligament Deficiency, and Their Repair Reduces Laxity.

Background: Injury to the posteromedial meniscocapsular junction has been identified after anterior cruciate ligament (ACL) rupture; however, there is a lack of objective evidence investigating how this affects knee kinematics or whether increased laxity can be restored by repair. Such injury is often overlooked at surgery, with possible compromise to results.

Hypotheses: (1) Sectioning the posteromedial meniscocapsular junction in an ACL-deficient knee will result in increased anterior tibial translation and rotation.

Posterior ankle impingement in professional soccer players: effectiveness of sonographically guided therapy.

Objective: The objective of our study was to describe the use of MRI and evaluate the efficacy of sonographically guided injection of steroid and anesthetic in the management of posterior ankle impingement in elite athletes.

Conclusion: The results show a role for sonographically guided steroid and anesthetic injection into a posterolateral capsule abnormality in athletes with clinical posterior impingement. The procedure was well tolerated and allowed a rapid return to athletic activity in all patients.
