Posterior wall fractures of the acetabulum: treatment using an anatomical plate through direct posterior approach.
This study was aimed to measure the application of W-shaped acetabular angular plate (WAAP) through direct posterior approach (DPA) on the reconstruction of acetabular posterior wall fractures when compared with reconstruction plates. ⋯ The application of WAAP through DPA showed satisfactory preliminary clinical outcomes, showing promise to be an alternative technique for the treatment of acetabular posterior wall fractures.

Ossification of the posterior capitellum: description of a new pathology and its radiological appearance.
Boxer elbow and handball goalkeeper elbow are causes of impingement characterized by osteophytes formation at the olecranon and coronoid tip as well as their corresponding fossae. Herein, we present another distinct pathology in these patients: the formation of an exostosis at the posterolateral aspect of the elbow. ⋯ In patients without history of elbow trauma, bony irregularities of the posterior aspect of the capitellum may indicate ossification of the posterolateral aspect of the elbow, most likely caused by repetitive hyperextensions.

Influence of kinematic alignment on femorotibial kinematics in medial stabilized TKA design compared to mechanical alignment.
Worldwide more and more primary knee replacements are being performed. Kinematic alignment (KA) as one of many methods of surgical alignment has been shown to have a significant impact on kinematics and function. The aim of the present study was to compare KA and mechanical alignment (MA) with regard to femorotibial kinematics. ⋯ Relating to an increased internal rotation and a more precise medial pivot point, it can be concluded that KA combined with a MS implant design may partially support the reproduction of physiological knee joint mechanics.

Incidence of complications and revision surgery in HAART compliant HIV patients undergoing primary total hip and knee arthroplasty: an institutional review.
Human immunodeficiency virus (HIV) positive patients are at high risk for osteonecrosis along with age-related osteoarthritis, resulting in a high number of joint reconstruction surgeries at younger ages in these immunosuppressed patients. Few previous studies have reported on patient outcomes in HAART (highly active antiretroviral therapy) compliant patients undergoing primary arthroplasty. The aim of this study is to report one institution's overall rate of complications and revision in HAART-compliant patients after primary hip and knee arthroplasty. ⋯ Arthroplasty is a viable option for HAART-compliant patients. Most previous studies showing a higher risk for deep tissue infection and revision in HIV patients have not accounted for modern HAART. Our results show that compliance with HAART has vastly improved the outcomes of arthroplasty in these patients, while a history of IVDU is likely the largest risk factor for infection in this population.

Is there a difference in mobility and inpatient physical therapy need after primary total hip and knee arthroplasty? A decade-by-decade analysis from 60 to 99 years.
Extended inpatient rehabilitation (PT) after total hip (THA) and knee arthroplasty (TKA) has a significant impact on total care costs. As patients age, extended PT might be required following THA and TKA. This study examined the relationship between patient age, functional mobility, inpatient PT need, and discharge disposition in THA and TKA patients. ⋯ Patients in their eighth and ninth decade had less improvement in functional mobility during in-hospital rehabilitation and utilized more PT services. However, clinical results in the elderly are still satisfying and the data may be helpful for resource utilization planning and risk-adjustment in value-based payment models.
