BACKGROUND AND PURPOSE For 20 years, medical treatment of rheumatoid arthritis (RA) has been improving and the incidence of joint surgery has decreased. We investigated the rates of primary ankle joint arthrodesis and total ankle arthroplasty in patients with RA in Finland between 1997 and 2010 to establish whether trends have changed during that period. METHODS The annual figures for primary...

Residual hip impairments, such as decreased hip muscle moment and power during walking, have been reported in patients with total hip arthroplasty (THA). Meanwhile, greater ankle power has also been reported in these patients. We investigated the interaction between hip and ankle joints during walking to determine the effects of different ankle pushoff instructions on hip biomechanics in patien...

Purpose This study was performed to characterize the natural history of squeaking sounds that occur following total hip arthroplasty (THA) using ceramic-on-ceramic bearing surfaces and its potential correlation with clinical and/or radiological results. Materials and Methods This study included 47 patients who underwent THA between April 1999 and April 2005, and had at least 10 years of follo...

BACKGROUND More than 300 000 joint replacement operations are performed in Germany every year, and the number is rising. In this article, we consider the question of simultaneous bilateral joint replacement at the hips or knees. Such procedures are indicated in patients suffering from bilateral, symptomatic arthrosis. METHODS The article is based on a selective review of the relevant literatu...

To investigate the gait analysis of patients after total knee arthroplasty with posterior cruciate ligament retention rotating platform and fixed arthroplasty, so as to provide ideas for clinical rationalization treatment. A 82 preserving platforms were selected replacement in our hospital followed up 1 y. The joint Hospital special surgery score, Western Ontario McMaster Universities Osteoarth...

In 1890, Themistocles Gluck performed the first total wrist replacement, implanting an ivory ball-and-socket prosthesis in a 19-year-old male patient with tuberculosis. Although Gluck’s first patients suffered from persistent infection, his subsequent patients demonstrated good long-term results. Despite initial successes, the use of wrist arthroplasty has made slow progress within the orthopae...

DESPITE THE PROVEN EFFECTIVENESS OF TOTAL joint replacement (TJR) surgery in relieving advanced knee and hip arthritis pain, TJR outcomes have come under intense public scrutiny in recent years. The 2010 recall of ASR metal-on-metal hip implants heightened awareness of the importance for implant safety surveillance for this high-cost and high-use procedure and exposed the need for a national sy...

Metallic endoprostheses are used for oncological reconstruction around the proximal femur and hip joint. Common modes of failure with hemiarthroplasty or standard hip arthroplasty after proximal femoral replacement include dislocation, late hip pain, and infection. The authors reviewed hospital records to identify patients undergoing constrained tripolar hip arthroplasty for oncological reasons...

INTRODUCTION We report a rare case of an infected revision total knee replacement as a result of a Lactobacillus species infection. Lactobacillus infections have been associated with prolonged broad-spectrum antibiotic use. This can have implications in revision surgery, especially when patients have been on previous long-term suppressive antibiotic therapy. CASE PRESENTATION An 81-year-old B...

There is a high prevalence of anemia detected in the preoperative work-up of elective surgical patients preparing for total joint replacement. The impact of anemia in this population has significant implications due to elevations in postoperative morbidity and mortality. By using current clinical guidelines and medical evidence, clinicians can improve outcomes for these patients by employing a ...
