Autologous minced cartilage implantation in osteochondral lesions of the talus-does fibrin make the difference?
Implantation of minced cartilage is a one-step-procedure that leads to satisfactory results in osteochondral defects. ⋯ Autologous minced cartilage implantation seems to be sufficient as a viable, one-step treatment for osteochondral lesions of the talus. It leads to low complication rates and excellent AOSS values within a 12-month period whereas the application of fibrin as the last fixation layer seems to be advisory, which demands further investigation.

Multicenter StudyPredictors of functional recovery following surgical repair of quadriceps tendon rupture: insights from a German multicentre study.
More extensive and cohesive studies on quadriceps tendon rupture (QTR) repair surgery are required to guide effective treatment strategies. Therefore, in this study, we aimed to identify predictors of subjective functional recovery following QTR repair surgery. ⋯ IV-Retrospective cohort study without a comparison group.

Increased stiffness with medial column screw supplementation of lateral locking plate for distal femur fractures: a biomechanical study.
We propose and assess the biomechanical stability of medial column screw supplementation in a synthetic distal femur fracture model. ⋯ This is the first study to evaluate the contribution of a medial column screw in a distal femur fracture model. PWS had superior stiffness and few failures compared to PA. Applied clinically, a medial column screw can increase construct stability in the setting of complex distal femur fractures with minimal increase in operative time, patient morbidity and cost.

Blood management protocol for baseline anemic patients undergoing hip arthroplasty.
Patients undergoing total hip arthroplasty (THA) with preoperative anemia are at higher risk for transfusion. Blood-conserving interventions can reduce perioperative transfusions. This retrospective study evaluates the efficacy and safety of a patient blood management (PBM) protocol in elective primary THA patients with preoperative anemia. ⋯ THA patients with baseline Hb < 12 g/dL had a zero-transfusion rate and significantly lower blood loss than those with Hb ≥ 12 g/dL. Optimizing preoperative Hb levels above 12 g/dL is not necessary for patients undergoing standard THA. Optimizing preoperative Hb may not be necessary for patients with baseline anemia due to their low blood loss. The PBM protocol was effective in conserving blood, time, and resources, offering a viable alternative for blood conservation in elective hip arthroplasty.

ReviewDesign features of the rotating head total hip arthroplasty by Weber-Huggler- a forgotten technical solution to reduce wear.
Total hip arthroplasty (THA) is a very successful operation. Once the problem of implant fixation was solved with the use of bone cement, the next development steps focused on improving the bearing. Weber, a Swiss surgeon, introduced the first modular heads in THA. ⋯ The features and results of this exceptional design are reviewed. However, as newer material combinations greatly mitigated the problem of wear and as the dimensions of the cylindrical connection limit range of motion, it was supplanted by the nowadays well-established Morse taper connection, which also is less complex to manufacture. As Weber's design was associated with good long-term results, the technical features of this technical solution should not be forgotten.
