Randomized Controlled Trial
Subsartorial adductor canal vs femoral nerve block for analgesia after total knee replacement.
Providing effective analgesia for total knee arthroplasty (TKA) patients remains challenging. Femoral nerve block (FNB) offers targeted pain control; however, its effect on motor function, related fall risk and impact on rehabilitation has been the source of controversy. Adductor canal block (ACB) potentially spares motor fibres of the femoral nerve, but the comparative effect of the two approaches has not yet been well defined due to considerable variability in pain perception. Our study compares both single-shot FNB and ACB, side to side, in the same patients undergoing bilateral TKA. ⋯ Although we could not confirm a benefit in motor function between ACB and FNB, given the equivalent analgesic potency combined with its potentially lower overall impact if neuropraxia should occur, ACB may represent an attractive alternative to FNB.

Meniscus injuries are the most commonly reported in athletes. Meniscectomy is the most common treatment. Stable peripheral tears may heal, while degenerative tears do well with physical therapy. However, the exact role of physical therapy in treating symptomatic unstable meniscal tears is not known. We aimed to identify the role of physical therapy in treating such patients and clarify the role of arthroscopic partial meniscectomy in treating unstable meniscal tears. ⋯ Pain and swelling improved after physical therapy. However, patients were not satisfied as limited range of knee motion persisted. APM was superior to physical therapy in treating symptomatic unstable meniscal tears, with high patient satisfaction and restored knee function.

Comparative Study
Arthroplasty compared to internal fixation by locking plate osteosynthesis in comminuted fractures of the distal humerus.
The purpose of this study was to evaluate and compare the results after double locking plate osteosynthesis (ORIF) and total elbow arthroplasty (TEA) in AO type C fractures of the distal humerus. ⋯ TEA and ORIF lead to comparable functional results, but major complications are more common after ORIF. Despite this, ORIF remains the gold standard for younger and older patients because of the lifelong loading limitation after TEA, unknown implant survival and problematic revision surgery. For patients older than 60 years a primary TEA can be recommended in exceptional cases, if the loading limitation is acceptable for the individual or the fracture is not reconstructable.

Shoulder pain is a common disorder. Despite growing evidence of the importance of physiotherapy, in particular active exercise therapy, little data is available to guide treatment. The aim of this project was to contribute to the development of an internationally accepted assessment and treatment algorithm for patients with shoulder pain. ⋯ The assessment and treatment algorithm presented could contribute to a more formal, extensive process aimed at achieving international agreement on an algorithm to guide physiotherapy treatment for shoulder pain.

Revision of failed total hip arthroplasty with severe acetabular bone loss represents a rare but challenging problem. Anatomic reconstruction with biological defect augmentation as solid bone transplants or cancellous bone restores bone stock while providing good component stability. The objective of this study was to present short- to mid-term results of revision total hip arthroplasty with a modular ring system in a consecutive series of patients with severe acetabular bone loss. ⋯ By achieving stable implant fixation and providing potential for biological fixation, treatment of severe acetabular bone loss in revision total hip arthroplasty with the modular ring system MRS-Titan provides a durable solution with good clinical and radiographic results and allows us to accomplish major goals of reconstruction.
