High failure rate 10.8 years after vastus medialis transfer and lateral release (Green's quadricepsplasty) for recurrent dislocation of the patella.
In adolescent patients with recurrent patellar dislocation, the Green's quadricepsplasty stabilizes the patella in a combination of a lateral release, a transfer of the medial head of the quadriceps onto the lateral part of the patella and an imbrication of the medial patellar retinaculum and joint capsule. This study aimed to evaluate the long-term performance, considering re-dislocations and functional outcomes. We hypothesized a high failure rate in the long term. ⋯ IV.

Predictive factors for failure of anterior cruciate ligament reconstruction via the trans-tibial technique.
Factors for graft failure after trans-tibial (TT) ACL reconstruction, including anterolateral ligament (ALL) injury and degree of synovialization, remain unclear. This study is to evaluate the risk factors for graft failures after TT ACL reconstruction including ALL injury and synovialization. ⋯ IV, retrospective cohort study.

Quantification and influencing factors of perioperative hidden blood loss during intramedullary fixation for intertrochanteric fractures in the elderly.
We aimed to quantify perioperative hidden blood loss (HBL) and investigate its influencing factors in elderly patients with intertrochanteric fractures (IFs) undergoing intramedullary fixation surgery. ⋯ IFs in elderly patients undergoing intramedullary fixation surgery were associated with significant perioperative HBL and anemia. Persistent HBL occurred before the operation and on the first few postoperative days. Surgeons should pay more attention to preoperative HBL in patients with fracture types AO/OTA 31-A2.2 to A3.3 and regularly measure Hb levels preoperatively to avoid anemia. Shortening preoperative time may helps to reduce preoperative blood loss.

Surgical outcomes of simple distal femur fractures in elderly patients treated with the minimally invasive plate osteosynthesis technique: can percutaneous cerclage wiring reduce the fracture healing time?
Achieving adequate reduction is difficult when performing minimally invasive plate osteosynthesis (MIPO) in elderly patients with simple distal femur fracture. This study aimed to evaluate the elderly patients who had undergone percutaneous wiring-assisted reduction with MIPO for simple distal femur fractures to determine the effect of this technique on reduction quality and fracture union. ⋯ Surgical treatment of simple spiral distal femur fractures with percutaneous cerclage wiring-assisted reduction and the MIPO technique in elderly patients resulted in better reduction and faster union time. Therefore, this technique could be a good solution if used in accordance with the indication.

Selective medial release using multiple needle puncturing with a spacer block in situ for correcting severe varus deformity during total knee arthroplasty.
We aimed to establish a selective and sequential medial release technique using multiple needle puncturing (MNP) with a spacer block in situ in severe varus deformity during total knee arthroplasty (TKA) and to investigate its efficacy and safety. ⋯ The selective and sequential technique using posterior clearing and/or MNP with a spacer block in situ can be a reliable option for managing medial tightness in severe varus deformity during primary TKA.
