Randomized Controlled TrialBone remodelling after femoral short stem implantation in total hip arthroplasty: 1-year results from a randomized DEXA study.
Short stem prostheses have been developed to preserve proximal femoral bone stock. This prospective, randomized study compared periprosthetic bone remodelling following short and straight stem implantation 1 year after surgery. ⋯ One year after surgery, both stems showed an implant-specific periprosthetic bone remodelling. Nevertheless, proximal load transfer was more pronounced after short stem implantation than with a straight stem.

Observational StudyReliability of Tönnis classification in early hip arthritis: a useless reference for hip-preserving surgery.
The Tönnis classification is widely accepted for grading hip arthritis, but its usefulness as a reference in hip-preserving surgery is yet to be demonstrated. We aimed to evaluate reproducibility of the Tönnis classification in early stages of hip osteoarthritis, and thus determine whether it is a reliable reference for hip-preserving surgery. ⋯ The Tönnis classification is a poor method to assess early stages of hip osteoarthritis. These findings suggest that its routine use in therapeutic decision-making for conservative hip surgery should be reconsidered.

Comparative StudyEarly recovery after arthroscopic repair compared to open repair of the anterior talofibular ligament for lateral instability of the ankle.
To compare the early result between arthroscopic and traditional open repair of the anterior talofibular ligament (ATFL) with inferior extensor retinaculum (IER) reinforcement for lateral instability of the ankle (LIA). ⋯ Compared with the open procedure, arthroscopic ATFL repair with IER reinforcement for LIA had an equivalent clinical result at the 1-year follow-up and allowed early recovery after surgery.

Unicompartmental knee arthroplasty in patients over 75 years: a definitive solution?
The purpose of this study was to perform a mid-long-term clinical and radiographic evaluation of the results obtained in patients older than 75 years treated with minimally invasive unicompartmental knee arthroplasty (UKA). The hypothesis was that UKA is a viable solution for the definitive treatment of localized disease in this age group, with good results and a low failure rate. ⋯ UKA is a viable option for treating unicompartmental knee osteoarthritis. With the proper indications and an accurate technique UKA may be indicated also in very elderly patients with reduced complications and morbidity, and excellent survivorship.

Comparative StudyArthroscopic tenodesis versus tenotomy of the long head of biceps tendon in simultaneous rotator cuff repair.
Full thickness rotator cuff tears are a common cause of shoulder pain and disability. While the role of the rotator cuff seems to be well known, the clinical significance of the biceps tendon for shoulder function has still been a subject of controversy. The aim of this study was to evaluate differences between tenodesis or tenotomy in simultaneous rotator cuff repair. ⋯ Level IV, retrospective case series.
