Isolated Complete Rupture of the Biceps Femoris Insertion: A Surgical Repair Technique Manuscript.

Isolated rupture of the distal biceps femoris insertion is rare. Current literature offers limited case reports and outcome measures after surgical management. We describe a knotless suture anchor fixation technique for this tear pattern.

A Biomechanical Study of the Role of the Anterolateral Ligament and the Deep Iliotibial Band for Control of a Simulated Pivot Shift With Comparison of Minimally Invasive Extra-articular Anterolateral Tendon Graft Reconstruction Versus Modified Lemaire Reconstruction After Anterior Cruciate Ligament Reconstruction.

Purpose: To determine whether the deep fibers of the iliotibial band (dITB) or the anterolateral ligament (ALL) provides more control of a simulated pivot shift and whether a minimally invasive anterolateral reconstruction (ALR) designed to functionally restore the ALL and dITB is mechanically equivalent to a modified Lemaire reconstruction (MLR).

Methods: Six matched pairs of cadaveric knees (N = 12) were subjected to a simulated pivot shift to evaluate anteroposterior translation; internal rotation; and valgus laxity at 0°, 30°, and 90° of flexion. The anterior cruciate ligament (ACL) was sectioned in all specimens, and retesting was performed.

Knotless Arthroscopic Reduction and Internal Fixation of a Displaced Anterior Cruciate Ligament Tibial Eminence Avulsion Fracture.

Generally occurring in the 8- to 14-year-old population, tibial eminence avulsion fractures are a common variant of anterior cruciate ligament ruptures and represent 2% to 5% of all knee injuries in skeletally immature individuals. In this article, we report on a new arthroscopic reduction and internal fixation technique that involves 2 absorbable anchors with adjustable suture-tensioning technology. This technique optimizes reduction and helps surgeons avoid proximal tibial physeal damage, procedure-related morbidity, and additional surgery.

Case Series With Histopathologic and Radiographic Analyses Following Failure of Fresh Osteochondral Allografts of the Talus.

Background: Fresh osteochondral allografting of the talus is one treatment option for large chondral defects. Following positive early term results, failure rates of up to 35% have been reported. A retrieval study was performed to characterize failed talar allografts.
