Randomized Controlled TrialDoes single use of an autologous transfusion system in TKA reduce the need for allogenic blood?: a prospective randomized trial.
Mechanical autotransfusion systems for washed shed blood (WSB) were introduced to reduce the need for postoperative allogenic blood transfusions (ABTs). Although some authors have postulated decreased requirements for ABT by using autologous retransfusion devices, other trials, mostly evaluating retransfusion devices for unwashed shed blood (USB), verified a small or no benefit in reducing the need for postoperative ABT. Because of these contradictory findings it is still unclear whether autologous retransfusion systems for WSB can reduce transfusion requirements. ⋯ Level II, therapeutic study.

Intramedullary nails result in more reoperations than sliding hip screws in two-part intertrochanteric fractures.
Sliding hip screws (SHSs) and intramedullary (IM) nails are well-documented implants for simple two-part intertrochanteric fractures; however, there is no consensus regarding which type of implant is better. ⋯ Level III, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

Surgical technique: talar neck osteotomy to lengthen the medial column after a malunited talar neck fracture.
Treatment of malunited talar neck fractures is challenging, and few studies address anatomic reconstruction as an alternative to arthrodesis. We describe a new surgical approach attempting to improve function and avoid development of degenerative changes in the adjacent joints. ⋯ Level IV, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

Can fresh osteochondral allografts restore function in juveniles with osteochondritis dissecans of the knee?
Failure of initial treatment for juvenile osteochondritis dissecans (OCD) may require further surgical intervention, including microfracture, autograft chondrocyte implantation, osteochondral autografting, and fresh osteochondral allografting. Although allografts and autografts will restore function in most adults, it is unclear whether fresh osteochondral allograft transplantations similarly restore function in skeletally immature patients who failed conventional treatment. ⋯ Level IV, case series.
