Meta AnalysisDoes unicompartmental knee arthroplasty have worse outcomes in spontaneous osteonecrosis of the knee than in medial compartment osteoarthritis? A systematic review and meta-analysis.
The role of unicompartmental knee arthroplasty (UKA) in spontaneous osteonecrosis of the knee (SONK) remains controversial, even though SONK involves only one compartment of the knee joint. We aimed to compare the survival rate and clinical outcomes of UKA in SONK and medial compartment osteoarthritis (MOA) via a meta-analysis of previous studies. ⋯ Cemented UKA has similar survival and clinical outcomes in SONK and MOA. Prospective studies designed specifically to compare the UKA outcomes in SONK and MOA are necessary.

Arthroscopic excision of wrist ganglions: does trans-cystic or cystic-sparing portal technique affect clinical outcomes?
The preliminary results of arthroscopic wrist ganglionectomy were contradictory. The approach used for the arthroscopic excision of wrist ganglions may play an important role. We analyzed two surgical approaches for arthroscopic excision of wrist ganglions. ⋯ For performing arthroscopic resection of wrist ganglions, both techniques are safe regarding the complication rates. In recurrence rate, no significant difference was found between the two groups, but no recurrence was observed when the TCP technique was used.

Outcome of short versus long interval in two-stage exchange for periprosthetic joint infection: a prospective cohort study.
A two-stage exchange is the standard treatment approach for chronic periprosthetic joint infection (PJI). While a 6-8 week interval is commonly used before reimplantation, the optimal length of the prosthesis-free interval has not yet been determined. We evaluated the influence of a short (< 4 weeks) and long (≥ 4 weeks) interval on reinfection rate and functional outcome of hip and knee PJI. ⋯ This study suggests that two-stage exchange with short interval has a similar outcome than with long interval, when highly active antibiotic therapy is used. Patient inconvenience and care costs due to immobilization were lower when strategies with a short interval were used.

Persistent postoperative step-off of the posterior malleolus leads to higher incidence of post-traumatic osteoarthritis in trimalleolar fractures.
Traditionally, size of the posterior fragment is considered the most important indicator for fixation in trimalleolar fractures. It remains unclear which factors contribute to worse functional and radiological outcome. This study was designed to determine predictors for the development of posttraumatic osteoarthritis and worse functional outcome in trimalleolar fractures. ⋯ Level IIB.

Attrition of rotator cuff without progression to tears during 2-5 years of conservative treatment for impingement syndrome.
The purpose of this study was to investigate the natural history of intact rotator cuff in impingement syndrome patients with concomitant spur protruding from the undersurface of acromion. ⋯ Therapeutic case series Level IV.
