Clinical TrialIncidence and radiologic predictor of postoperative patellar instability after Fulkerson procedure of the tibial tuberosity for recurrent patellar dislocation.
Excellent results of anteromedialization of the tibial tuberosity for recurrent patellar dislocation have been reported; however, the contribution of the preoperative anatomic factors to postoperative patellar instability has not been well established. The purpose of this study was to investigate the mid-term results and the incidence of postoperative patellar instability after Fulkerson procedure for recurrent patella dislocation, and to determine the radiologic predictor of the postoperative patellar instability. ⋯ Case-control study, Level III.

Randomized Controlled Trial Comparative StudySubacromial patient-controlled analgesia with ropivacaine provides effective pain control after arthroscopic rotator cuff repair.
To investigate the postoperative analgesic effect of subacromial patient-controlled analgesia (SA-PCA) with ropivacaine in comparison with intravenous patient-controlled analgesia (IV-PCA) after arthroscopic rotator cuff repair. ⋯ Therapeutic study, Level I.

Clinical TrialCell-free collagen type I matrix for repair of cartilage defects-clinical and magnetic resonance imaging results.
Several well-described techniques are available for the treatment of chondral and osteochondral defects. The aim of the study was to assess the efficacy of a single-stage procedure incorporating a new cell-free collagen type I gel for the treatment of small chondral and osteochondral defects in the knee evaluated at 2-year follow-up. ⋯ IV.

Comparative StudyBiomechanical properties of repairs for dislocated AC joints using suture button systems with integrated tendon augmentation.
To evaluate the biomechanical performance of different techniques for CC reconstruction using suture button systems with integrated tendon augmentation. Hypothesis was that (1) reconstructions using a cortical button combined with a biological augmentation (semitendinosus allograft) will demonstrate improved stability than a modified Weaver-Dunn procedure and (2) constructs using two tunnels at the clavicle for fixation will show superior horizontal stability than single-tunnel constructs. ⋯ Controlled laboratory study.

Effect of BMP-12, TGF-β1 and autologous conditioned serum on growth factor expression in Achilles tendon healing.
Achilles tendon ruptures are devastating and recover slowly and incompletely. There is a great demand for biomolecular therapies to improve recovery, yet little is understood about growth factors in a healing tendon. Here, the role of growth factors during tendon healing in a rat model and their reaction to single and multiple growth factor treatment are explored. ⋯ bFGF, BMP-12, VEGF and TGF-β1 are differentially expressed during tendon healing. Additional BMP-12 or TGF-β1 has no significant influence, whereas ACS generally increases expression of all factors except VEGF. Staged application of multiple growth factors may be the most promising biomolecular treatment.
