Arthroscopic reconstruction of the popliteus complex: accuracy and reproducibility of a new surgical technique.

Purpose: With combined PCL reconstruction and a minimal invasive (extra-anatomical) Larson's procedure, dorsal instability can be reduced by about 50-70 %. Better results are described by open and more anatomical procedures. In this study, a new, standardized, arthroscopic technique for anatomical popliteus tendon (PLT) reconstruction is evaluated.

Fate of large donor site defects in osteochondral transfer procedures in the knee joint with and without TruFit plugs.

Introduction: Because of the potential donor site morbidity, cartilage lesions of more than 3 cm(2) in size are considered to be critical regarding autologous osteochondral transplantation (OCT). In this study, the potential donor site morbidity for large defects should be reduced by means of OBI TruFit Plugs.

Materials And Methods: An autologous OCT was carried out on 37 patients and the cylinders were received from the dorsal medial femoral condyle.

Ulnar head replacement and related biomechanics.

A stable distal radioulnar joint (DRUJ) is mandatory for the function and load transmission in the wrist and forearm. Resectional salvage procedures such as the Darrach procedure, Bowers arthroplasty, and Sauvé-Kapandji procedure include the potential risk of radioulnar instability and impingement, which can lead to pain and weakness. Soft tissue stabilizing techniques have only limited success rates in solving these problems.
