Comparative StudyHead size in Delta ceramic-on-ceramic total hip arthroplasty: a comparative registry study.
Optimal bearing size in total hip arthroplasty (THA) has not been clearly ascertained, but large diameter ceramic balls may improve function and implant stability, with minimal concerns for wear. Delta ceramic-on-ceramic (COC) THA were stratified based on head diameter (32, 36 and 40 mm), aiming to assess: 1) survival rates, reasons for revision and hazard ratios for failure; 2) survival rates and hazard ratios for aseptic loosening, dislocation/primary instability, liner failure. ⋯ IV (therapeutic study).

Understanding pelvic mobility is important to correctly diagnose and treat painful hips with positive impingement test in non-arthritic patients.
To determine repeatability of pelvic mobility, calculated as both change in sacral slope (∆SS) and pelvic tilt (∆PT), and evaluate their correlations with pelvic incidence (PI) in non-arthritic patients with hip pain and positive impingement test. ⋯ Level IV.

Comparative StudyCannulated compression screws with cable technique leads to a dramatic reduction in patella fracture fixation complications compared to tension band wiring.
The aim of this study was to compare the clinical, radiological and functional outcomes between cannulated compression screw with cable construct (CS) and tension band wiring (TBW) in transverse patella fractures. ⋯ The CS technique demonstrated lower complications, in particular, no CS patient had implant removals, wire migration or fracture displacement. Additionally, CS technique showed a faster return to ambulation and time to achieving full weight bearing status.

Observational StudyAssocation between trapezium size and failure of total trapeziometacarpal prosthesis. A survival analysis.
To assess the survival function of cementless total trapezium metacarpal prostheses (TTMPs) at 20 years, to compare survival functions by trapezium size, and to evaluate the association between the instantaneous risk of TTMP failure and small trapezium size using a multivariate Cox regression model. ⋯ These results confirm the long-term functional survival of TTMP prostheses and reveal a significant increase in trend of the survival curve with larger trapezium size. Patient age, trapezium morphology, and the presence of post-surgical complications are confounders in the association between small trapezium size and the hazard ratio of TTMP failure.

Previous arthroscopy does not decrease survivorship or functional outcomes for unicompartmental knee arthroplasty patients.
Arthroscopic procedures for osteoarthritis (OA), in particular arthroscopic meniscectomy, have poorer long-term clinical outcomes compared to those managed non-operatively. In addition, previous arthroscopy is associated with worse outcomes following subsequent total knee arthroplasty (TKA), however there is limited data on the impact on subsequent unicompartmental knee arthroplasty (UKA) outcomes. The aim of the study is to investigate whether patients who had arthroscopy prior to UKA have differences in survivorship or functional outcomes compared to those with no prior arthroscopy. ⋯ In this large patient cohort with comprehensive review of clinical data and outcomes, we found that prior arthroscopy did not affect survivorship or functional outcomes of UKA patients.
