The aims of this study were to evaluate the anatomic feasibility of medial patellofemoral ligament (MPFL) reconstruction using a part of the adductor magnus tendon and to identify possible risks. ⋯ Anatomic knowledge is essential during adductor magnus tendon harvest to avoid damage to neurovascular structures. The adductor magnus tendon is an interesting alternative graft option for MPFL reconstruction if anatomic dangers are considered and avoided.

Comparative Study
Fractures around the lateral cortical hinge after a medial opening-wedge high tibial osteotomy: a new classification of lateral hinge fracture.
The purpose of this study was to determine the frequency of lateral hinge fractures after opening-wedge high tibial osteotomy and investigate the patterns of fracture and their clinical outcome. ⋯ Level IV, therapeutic case series.

Comparative Study
Two-year outcomes of open shoulder anterior capsular reconstruction for instability from severe capsular deficiency.
To document outcomes after anterior capsulolabral reconstruction for recurrent shoulder instability in 15 patients (20 shoulders) who have had multiple failed stabilizations or collagen disorders. ⋯ Level IV, therapeutic case series.

Anterior impression fractures of the humeral head (reverse Hill-Sachs lesions) are typical concomitant bony injuries of posterior shoulder dislocations. When more than 20% of the humeral articulating surface is affected, surgical treatment is required, typically necessitating open surgery. Recently, cases of successful arthroscopic treatment of small reverse Hill-Sachs lesions involving less than 30% of the articulating surface have been reported. ⋯ However, at 6 months' follow-up, the patient presented with pain and symptoms of a frozen shoulder. Cross-sectional imaging showed necrosis, partial absorption, and loss of reduction of the formerly elevated segment requiring humeral head replacement. This case report shows that even though the arthroscopic retrograde elevation of large reverse Hill-Sachs lesions is technically achievable, the outcome can be unsatisfactory because of the limitations in biologic healing response associated with large lesions of the humeral articulating surface.
