We retrospectively reviewed 54 patients (92 hips) who underwent cementless total hip arthroplasty for bony ankylosis in ankylosing spondylitis between September 1988 and 2002. The mean age of the patients was 25.5 years. The mean duration of follow-up was 8.5 years. ⋯ Heterotopic ossification was seen in 12 patients; reankylosis rate was 0%. Thirteen (14%) arthroplasties were revised because of aseptic loosening. Kaplan-Meier survivorship analysis with revision as end point revealed 98.8% survival at 5 years and 85.8% survival at 8.5 years follow-up.

Pain control after arthroplasty has been a key concern for orthopedic surgeons. After total knee arthroplasty (TKA), a small group of patients developed a painful joint with suboptimal range of motion. Manipulation under anesthesia increases flexion and extension while decreasing pain in most cases. ⋯ Group A had an incidence of manipulation of 4.75% (37/778). Of 357 patients, 8 required manipulation in group B, which is an incidence of 2.24%. We recommend that orthopedic surgeons consider using a multimodal pain management protocol for TKA.

Total joint arthroplasty is a safe and successful procedure. However, numerous complications may present after elective arthroplasty. This study prospectively collected data on systemic and local in hospital complications after 15383 joint arthroplasties, which included 8230 total hip arthroplasties and 7153 total knee arthroplasties. ⋯ There were 109 major local complications, including 16 vascular injuries, 29 peripheral nerve injuries, 25 periprosthetic fractures, and 18 dislocations. Total joint arthroplasty, despite its success, can be associated with rare serious and life-threatening complications. This study provides a baseline of complications that can occur after elective joint arthroplasty.

Randomized Controlled Trial Multicenter Study Comparative Study
Prospective randomized clinical trial comparing hemiarthroplasty to total hip arthroplasty in the treatment of displaced femoral neck fractures: winner of the Dorr Award.
The Displaced Femoral (neck fracture) Arthroplasty Consortium for Treatment and Outcomes study is a prospective, multicenter randomized clinical trial comparing hemiarthroplasty to total hip arthroplasty (THA) in the treatment of displaced femoral neck fractures in previously independent patients. Primary outcomes were measured at 6, 12, and 24 months with the Short Form-36 (SF-36), Western Ontario and McMaster Osteoarthritis Index (WOMAC), and the Harris Hip Score and the Timed "Up & Go" Test. ⋯ Total hip arthroplasty patients also had superior WOMAC function scores (81.8 +/- 10.2 vs 65.1 +/- 18.1, P = .03). Significant differences in outcomes, without a significantly greater incidence of complications, suggest THA is a valuable treatment option for the active elderly hip fracture population.

Injury of the infrapatellar branch of the saphenous nerve (ISN) may be caused by a surgical laceration or trauma about the knee and can result in formation of a painful neuroma. There has been no report of knee stiffness after a total knee arthroplasty secondary to a painful neuroma of the ISN. ⋯ A neuroma of the ISN was resected, and the pain as well as the stiffness of the knee resolved. A source of pain such as a neuroma should be considered as a cause of reversible knee stiffness or "pseudoarthrofibrosis" after a total knee arthroplasty.
