Autologous chondrocyte implantation in the knee: mid-term to long-term results.
From 1998 to 2008, 1000 skeletally mature patients underwent autologous chondrocyte implantation for an osteochondral defect of the knee. We evaluated the functional outcomes in 827 of 869 patients who had undergone autologous chondrocyte implantation with Chondron or periosteum (ACI-C/ACI-P) or matrix-assisted chondrocyte implantation (MACI) and attempted to identify factors that influenced outcome. ⋯ Therapeutic Level IV.

Randomized Controlled Trial Comparative StudyThe relative efficacy of antifibrinolytics in adolescent idiopathic scoliosis: a prospective randomized trial.
Antifibrinolytics can reduce intraoperative blood loss. The primary aim of this study was to determine the efficacy of intraoperative tranexamic acid, epsilon-aminocaproic acid, and placebo at reducing perioperative blood loss and the transfusion rate in patients with adolescent idiopathic scoliosis undergoing posterior spinal arthrodesis. ⋯ Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Randomized Controlled Trial Comparative StudyA randomized, controlled, prospective study evaluating the effect of patellar eversion on functional outcomes in primary total knee arthroplasty.
Patellar mobilization technique during total knee arthroplasty has been debated, with some suggesting that lateral retraction, rather than eversion, of the patella may be beneficial. We hypothesized that patients with knees surgically exposed using patellar lateral retraction would have comparable outcomes with patients with knees surgically exposed using patellar eversion. ⋯ Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Randomized Controlled Trial Comparative StudyBicruciate substituting design does not improve maximal flexion in total knee arthroplasty: a randomized controlled trial.
An important factor in the functional results after total knee arthroplasty is the achieved maximal flexion. The main purpose of this study was to compare the maximal knee flexion one year after surgery in patients who received either the bicruciate substituting knee system or the conventional posterior stabilized system. ⋯ Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Observational StudyThe impact of depression and pain catastrophization on initial presentation and treatment outcomes for atraumatic hand conditions.
Prior studies have suggested that patient-rated hand function is impacted by depression and pain catastrophization. We studied the impact that these comorbidities have on treatment outcomes. ⋯ Prognostic Level I. See Instructions for Authors for a complete description of levels of evidence.
