Background: The projected increase in revision shoulder arthroplasty has increased interest in the outcomes of theseprocedures. Glenoid component removal and conversion to a hemiarthroplasty (HA) is an option for aseptic glenoidloosening after anatomic total shoulder arthroplasty (aTSA).Methods: We identified patients who had undergone revision shoulder arthroplasty over a 15-...

background:  conventional treatments after complicated injuries of the distal radioulnar joint (druj) such as darrach and kapandji-sauvé procedures have many drawbacks, which may eventually lead to a painful unstable distal ulna.  the development of druj prosthesis has significantly evolved over the past years. in this study, we assessed the outcome results of patients after druj implant arthro...

BACKGROUND Unicompartmental knee arthroplasty is a less-invasive alternative to total knee arthroplasty for patients with arthritis affecting only the medial or lateral compartment. However, little is known about recent trends in the use of these procedures and the associated outcomes among older patients. METHODS With use of a nationally representative 5% sample of Medicare beneficiaries who...

Synovial chondromatosis affecting the glenohumeral joint is rare. Treatment primarily consists of arthroscopic loose body removal and synovectomy. Shoulder arthroplasty has been mentioned in the literature as a treatment option for patients with coexisting arthritis, although the results have been underreported. The case of an 84-year-old man with long standing synovial chondromatosis of the sh...

QUESTION Do people who have had revision arthroplasty report more limitations and less physical activity than those after primary total hip arthroplasty? Can degree of limitation and physical activity be predicted by revision arthroplasty, after adjustment for age, gender, and Charnley classification? DESIGN Cross-sectional observational study. PARTICIPANTS 371 people after primary and 134 ...

BACKGROUND AND PURPOSE An increasing number of patients have several joint replacement procedures during their lifetime. We investigated the use and suitability of multi-state model techniques in providing a more comprehensive analysis and description of complex arthroplasty histories held in arthroplasty registries than are allowed for with traditional survival methods. PATIENTS AND METHODS ...

The most common organisms causing prosthetic knee joint infections are staphylococci. However, arthroplasty infections with atypical microbial pathogens, such as Mycobacteria can occur. Due to the rarity of mycobacterial prosthetic joint infections, diagnosis, treatment, and management of these atypical infections represent a clinical challenge. A 71-year old female post-operative day 40 after ...

BACKGROUND As shoulder arthroplasty becomes more common, the number of failed arthroplasties requiring revision is expected to increase. When revision arthroplasty is not feasible, resection arthroplasty has been used in an attempt to restore function and relieve pain. Although outcomes data for resection arthroplasty exist, studies comparing the outcomes after the removal of different primary ...

Twenty-six consecutive cases of infected primary total knee arthroplasties were treated at our institution from 1989 through 2000. Eleven patients had debridement and irrigation performed within 2 months of index arthroplasty or hematogenous spread; only one infection was eradicated. Twenty-five patients had their prostheses removed; 17 had two-stage revision arthroplasty, following which infec...

Background: The purpose of this study was to determine a correlation between surgical case order and the length ofoperative time, total length of time in the operating room, time until discharge from the hospital, and the incidence ofintraoperative complications for primary total shoulder arthroplasty cases.Methods: A retrospective review was conducted of records for all individual primary tota...
