Comparative StudyThe prevalence of groin pain after metal-on-metal total hip arthroplasty and total hip resurfacing.
Groin pain after total hip arthroplasty (THA) or total hip resurfacing arthroplasty can be troubling for patients and surgeons. Potential sources of pain include infection, loosening, metal hypersensitivity, or impingement of bony structures or the iliopsoas tendon. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Retrospective analysis of infection rate after early reoperation in total hip arthroplasty.
Infection is a devastating complication of total hip arthroplasty (THA). Unavoidable reoperation during the acute recovery phase of hip arthroplasty has the potential for an increased infection rate but the risk is not well established nor is the fate of these infected hips. ⋯ Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Do the potential benefits of metal-on-metal hip resurfacing justify the increased cost and risk of complications?
Metal-on-metal hip resurfacing arthroplasty (MoM HRA) may offer potential advantages over total hip arthroplasty (THA) for certain patients with advanced osteoarthritis of the hip. However, the cost effectiveness of MoM HRA compared with THA is unclear. ⋯ Level I, economic and decision analysis. See Guidelines for Authors for a complete description of levels of evidence.

Case ReportsCase reports: two cases of glenohumeral chondrolysis after intraarticular pain pumps.
Acute idiopathic chondrolysis in young adults is rare. The etiology often is unknown and outcomes can be devastating owing to rapid development of painful secondary osteoarthritis. There have been some recent reports of chondrolysis after arthroscopic shoulder procedures. Animal and laboratory data suggest chondrolysis is related to the use of intraarticular pain pumps, although there is no conclusive evidence that this is causative in patients. ⋯ These cases provide additional evidence of an important association between postarthroscopic chondrolysis of the glenohumeral joint and the use of bupivacaine pain pumps.

Early experience with a novel nonmetallic cable in reconstructive hip surgery.
Metallic wires and cables are commonly used in primary and revision THA for fixation of periprosthetic fractures and osteotomies of the greater trochanter. These systems provide secure fixation and high healing rates but fraying, third-body generation, accelerated wear of the bearing surface, and injury to the surgical team remain concerning. ⋯ The nonmetallic periprosthetic cables used in this series provided adequate fixation to allow for both osteotomy and fracture healing. We did not observe any complications directly related to the cables. Level of Evidence Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.
