Comparative StudyClinical outcomes of patellofemoral arthroplasty: robotic assistance produces superior short and mid-term outcomes.
Patellofemoral arthroplasty (PFA) has been shown to provide symptomatic improvement for isolated patellofemoral osteoarthritis (PFOA). The efficacy of robotic-assisted PFA and the most suitable PFA implant design, however, remain ongoing matters of debate. This study sought to compare clinical outcomes between patients who underwent robotic-assisted versus conventional PFAs with inlay and onlay prosthetic designs. ⋯ III.

Understanding pelvic mobility is important to correctly diagnose and treat painful hips with positive impingement test in non-arthritic patients.
To determine repeatability of pelvic mobility, calculated as both change in sacral slope (∆SS) and pelvic tilt (∆PT), and evaluate their correlations with pelvic incidence (PI) in non-arthritic patients with hip pain and positive impingement test. ⋯ Level IV.

Open plate fixation in displaced pediatric proximal humerus fractures is safe and leads to very good functional outcomes.
In displaced pediatric proximal humerus fractures (PHF), surgical treatment ranges from closed to open procedures. Soft tissue interposition can impede closed reduction, making open techniques necessary. While K-wire fixation and elastic stable intramedullary nailing (ESIN) lead to good results, plate fixation could be an alternative in patients with limited growth potential and highly unstable or insufficiently retained fractures. Only few studies with low sample sizes have assessed plate fixation, yet. In this study, the outcome of pediatric PHFs treated with plate fixation was evaluated. ⋯ Plate fixation is a safe option in pediatric patients with limited growth potential and highly displaced PHFs. Plate fixation led to a good to excellent functional outcome, regardless of fracture morphology and implant positioning. A higher invasiveness and the need for implant removal must be considered.

Favorable early outcomes of medial unicompartimental knee arthroplasty in active patients presenting a degenerative medial meniscus root tear with meniscal extrusion and mild radiographic osteoarthritis.
There is only limited literature available evaluating the preferable treatment for active mid-age or elderly patients presenting with a degenerative medial meniscus root tear (d-MMRT) with medial meniscal extrusion (MME) and early-phase radiographic osteoarthritis (OA), failing to provide solid evidence. The aim of this study was to evaluate early outcomes of medial unicompartimental arthroplasty (mUKA) in active patients presenting a d-MMRT with meniscal extrusion and mild radiographic OA of the knee. To prove this claim we hypothesized that (1) patients with a d-MMRT with initial grade 1-3 KL OA of the medial compartment of the knee present the same pre-operative symptoms as patients with an end-stage grade 4 K-L OA, and that (2) those patients with d-MMRT and low-grade OA achieve the same early clinical and functional outcomes when treated with mUKA compared to patients with end-stage medial OA. ⋯ Favorable early clinical outcomes were obtained after mUKA in active mid-age and elderly patients presenting with degenerative medial meniscus root tear and mild isolated medial OA. Patients with mild no bone-on-bone OA but with degenerative medial meniscus root tear and medial meniscal extrusion presented the same or worse pre-operative symptoms as patients with end-stage medial OA and benefit the same from mUKA.
