Comparative StudyArthrosis of glenohumeral joint after arthroscopic Bankart repair: a long-term follow-up of 13 years.
The purpose of the study was to establish radiologic and clinical occurrence of glenohumeral arthrosis after arthroscopic Bankart repair. ⋯ Arthrosis rarely causes more than minor subjective symptoms or a minor objectively perceived disadvantage during 13 years' follow-up.

Partial allograft replacement of the radial head in the management of complex fracture-dislocations of the elbow.
There have been reports of total radial head allografts showing variable outcomes. This case series reports the novel use of an allograft for partial radial head replacement in the treatment of elbow fracture-dislocation. ⋯ Partial radial head allograft may be a useful alternative to radial head prosthesis in unstable fracture-dislocations in which the radial head cannot be restored fully.

Rotator cuff tears affect 40% or more of those aged older than 60 years, and repair failure rates of 20% to 70% remain a significant clinical challenge. Hence, there is a need for repair strategies that can augment the repair by mechanically reinforcing it, while at the same time biologically enhancing the intrinsic healing potential of the tendon. Tissue engineering strategies to improve rotator cuff repair healing include the use of scaffolds, growth factors, and cell seeding, or a combination of these approaches. ⋯ This article reviews the current basic science and clinical understanding of commercially available synthetic and extracellular matrix scaffolds for rotator cuff repair. Our review will emphasize the host response and scaffold remodeling, mechanical and suture-retention properties, and preclinical and clinical studies on the use of these scaffolds for rotator cuff repair. We will discuss the implications of these data on the future directions for use of these scaffolds in tendon repair procedures.

Comparative StudySuprapectoral or subpectoral position for biceps tenodesis: biomechanical comparison of four different techniques in both positions.
The aim of this study was to compare different techniques for tenodesis of the long head of biceps tendon (LHB) in the suprapectoral and subpectoral position to test the hypothesis that using shorter screws at the subpectoral position would achieve a similar primary ultimate failure load (UFL) as the longer screws at the suprapectoral position, that both types of tenodesis screws achieve comparable UFL, and that knotless suture anchor techniques can be performed at the subpectoral position in cortical bone and reach a UFL similar to tenodesis screws. ⋯ Due to the biomechanical testings interference screws are appropriate devices for suprapectoral and subpectoral biceps tenodesis resisting cyclic loading and attaining a satisfactory, whereas the knotless suture anchors sustained a significant about 50% lower UFL, and can only be recommended conditionally for LHB tenodesis regarding primary stability.
