The need for total hip arthroplasty in Perthes disease: a long-term study.
Legg-Calvé-Perthes disease (LCPD) was described a century ago. In previous long-term reports of patients with LCPD, nonoperative treatment varied considerably. The likelihood of hip osteoarthritis (OA) developing in patients with LCPD and possible need for THA are not well defined. ⋯ Level III, prognostic study. See Guidelines for Authors for a complete description of levels of evidence.

Comparative StudyMortality after distal femur fractures in elderly patients.
Hip fractures in the elderly are associated with high 1-year mortality rates, but whether patients with other lower extremity fractures are exposed to a similar mortality risk is not clear. ⋯ Level II, prognostic study. See the guidelines online for a complete description of evidence.

Comparative StudyTotal shoulder arthroplasty in older patients: increased perioperative morbidity?
More elderly patients are becoming candidates for total shoulder arthroplasty with an increase in frequency of the procedure paralleling the rise in other total joint arthroplasties. Controversy still exists, however, regarding the perioperative morbidity of total joint arthroplasty in elderly patients, particularly those 80 years of age and older. ⋯ Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Risk factors for revision of hip arthroplasties in patients younger than 30 years.
Numerous reports of THAs in patients younger than 30 years indicate a high risk of revision. Although risk factors for revision have been reported for older patients, it is unclear whether these risk factors are the same as those for patients younger than 30 years. ⋯ Level III, therapeutic study, case control study. See the Guidelines for Authors for a complete description of levels of evidence.

Durable infection control and function with the PROSTALAC spacer in two-stage revision for infected knee arthroplasty.
A two-stage revision total knee arthroplasty is recognized as the gold standard in the treatment of infection. However, traditional spacers limit function in the interval between the two stages and may cause instability, scarring, and bone erosion. The PROSTALAC knee spacer is an antibiotic-loaded cement articulating spacer that allows some movement of the knee between stages. Whether motion enhances long-term function is unknown. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.
