Randomized Controlled Trial Comparative StudyMatrix-induced autologous mesenchymal stem cell implantation versus matrix-induced autologous chondrocyte implantation in the treatment of chondral defects of the knee: a 2-year randomized study.
Cell-based strategies that combine in vitro- expanded autologous chondrocytes with matrix scaffolds are currently preferred for full-thickness cartilage lesions of the knee ≥2 cm(2). Although this approach is reasonable, continuing advances in the field of cartilage repair will further expand the options available to improve outcomes. ⋯ For the treatment of isolated full-thickness chondral lesion of the knee, m-AMI can be used effectively and may potentially accelerate recovery. A larger patient cohort and follow-up supported by histological analyses are necessary to determine long-term outcomes.

Medial triceps brachii free flap in reconstructive surgery: a prospective study in eight patients.
In this study, we present a prospective series of medial triceps free flaps for ankle and foot complex defects coverage and discuss its numerous advantages. ⋯ MTB free flap appears to be a useful option for covering small to medium defects in lower limb extremities. Due to the constant anatomy of the MTB nerve, we suggest that the flap could also be used as an innervated free flap for small or medium muscular reanimation such as sequelae of forearm and hand muscle impairment, or facial palsy.

Meta AnalysisIncidence of adjacent segment degeneration in cervical disc arthroplasty versus anterior cervical decompression and fusion meta-analysis of prospective studies.
To evaluate the incidence of adjacent segment disease (ASD) requiring surgical intervention between anterior cervical decompression and fusion (ACDF) and total disc replacement (TDR). ⋯ For patients with one-level cervical degenerative disc disease (CDDD), total disc replacement was found to have significantly fewer ASDs and reoperations compared with the ACDF. Cervical replacement arthroplasty may be superior to ACDF in ASD. Therefore, cervical arthroplasty is a safe and effective surgical procedure for treating CDDD. We suggest adopting TDR on a large scale.

Review Case ReportsAvulsion fracture of the acromial physis in a 14-year-old boy: a case report.
Scapular fractures are uncommon and among them acromial fractures are even more uncommon. Because the vast majority of acromial fractures are either non-displaced or minimally displaced, symptomatic and nonoperative management was performed. We describe a case of avulsion fracture of the acromial physis displaced by acromioclavicular ligament treated with open reduction and internal fixation, and include a review of the literature.

Multicenter StudyReversed shoulder arthroplasty with inversed bearing materials: 2-year clinical and radiographic results in 101 patients.
This study documents 2-year clinical and radiographic results following reversed total shoulder arthroplasty using a novel prosthesis with inverted bearing materials (polyethylene glenoid; metal humeral component). This design was intended to avoid massive PE abrasion on the humeral side. Therefore, we predicted a lack of subsequent osteolysis-induced exacerbation of scapular notching, and because of other design features and modified operating technique a reduced notching rate. ⋯ Inversion of the materials led to another type of notching with no signs of PE-induced osteolysis and no increase in the risk of short-term complications. Clinical results were comparable with other prostheses. Mid- to long-term results are required before any firm conclusions on clinical outcome and survival can be drawn.
