A "sandwich" method of reconstruction of the medial patellofemoral ligament using a titanium interference screw for patellar instability in skeletally immature patients.
No standard surgical procedure for medial patellofemoral ligament (MPFL) reconstruction exists in skeletally immature patients with patellar instability. This study aimed to evaluate the clinical effectiveness of a novel reconstruction technique for the MPFL in patients with patellar instability because of non-closure of the epiphyseal line. ⋯ The MPFL reconstruction methods, using a double-stranded semitendinosus autograft and sparing the femoral physeal line in non-closure of the epiphyseal line, provide acceptable short-term results for the treatment of patellar instability.

Randomized Controlled Trial Comparative StudyTape versus cast for non-operative treatment of primary patellar dislocation: a randomized controlled trial.
We hypothesized that taping results in better short-term functional outcome and comparable redislocation rates. ⋯ Tape bandage immobilization seems superior to a cylinder cast even after 5 years.

ReviewMedial coracoclavicular ligament revisited: an anatomic study and review of the literature.
The medial coracoclavicular ligament (MCCL), up to now rarely reported in the literature, was studied in a formol-fixed cadaver by means of dissection, morphometry, and light microscopy. This entity represents a true ligament within the coracoclavicular fascia. Although longer and narrower than its lateral counterpart, the medial coracoclavicular ligament follows the same morphological pattern, including the cartilage at the level of the coracoidal attachment. Its clinical significance and implications together with a review of the literature is presented.

Stress-related femoral cortical and cancellous bone density loss after collum femoris preserving uncemented total hip arthroplasty: a prospective 7-year follow-up with quantitative computed tomography.
Bone loss around uncemented femoral components is suspected to precede implant loosening and contribute to problems in revision surgery. Short-stemmed cementless femoral components are designed to preserve proximal femoral bone stock and ultimately the longevity of the prosthesis. ⋯ Proximal cortical and cancellous bone density loss and decrease of contact area indicate that metaphyseal fixation cannot be achieved. The lack of cortical BD loss and increase of contact area values below the trochanter minor suggest diaphyseal fixation.
