Object: Although pain relief is a primary goal of a total knee arthroplasty (TKA) and partial knee arthroplasty (PKA), a significant number of arthroplasty patients experience unexplained pain. This study attempts to determine preoperative or intraoperative factors that may predict pain after knee arthroplasty. Methods: 2585 primary TKAs and 423 PKAs were performed between 1993 and 2013. Infect...

Background: The ultimate goal of the treatment of infectious knee arthritis is to protect the articular cartilage fromadverse effects of infection. Treatment, however, is not always hundred percent successful and has a 12% failurerate. Persistent infection is more likely to happen in elderly patients and those with underlying joint diseases,particularly osteoarthritis. Eradica...

BACKGROUND Cardiac complications are a major cause of postoperative morbidity. The purpose of this study was to determine the rates, risk factors, and time of occurrence for cardiac complications within thirty days after primary unilateral total knee arthroplasty and total hip arthroplasty. METHODS The American College of Surgeons National Surgical Quality Improvement Program data set from 20...

OBJECTIVES To estimate the prevalence of preoperative World Health Organization (WHO) defined anaemia in patients presenting for revision hip and knee arthroplasty and its association with transfusion of allogeneic packed red blood cells (PRBC). BACKGROUND Studies have mainly investigated the prevalence of preoperative anaemia in primary and not revision hip and knee joint arthroplasty. MET...

The aim of this study was to evaluate the impact of total hip or knee arthroplasty upon quality of life in elderly patients. The study was carried out at the Clinic for Orthopaedic Surgery Lovran on 74 total hip arthroplasty and 70 total knee arthroplasty patients. All patients had completed the Medical Outcomes Study 36-Item Short Form in the week having preceded their surgery and then again p...

The purposes of this study were to determine the probabilities of subsequent lower extremity arthroplasty after index knee arthroplasty for osteoarthritis and to evaluate the demographic as well as radiographic factors that may predict progression to arthroplasty in the contralateral knee. Between 1984 and 1994, 646 patients, aged 40 to 75 years, with a primary cruciate-retaining knee were iden...

a 48‑year‑old morbidly obese woman with a left medial meniscal tear and moderately severe degenerative joint disease (djd) reported for 14‑month follow‑up visit from arthroscopic surgery. she reported a resolution of pain, swelling and an improved range of motion (rom). the patient was first evaluated 14 months ago, and at that time was considered a strong candidate for total knee replacement d...

periodic evaluation and monitoring the health and economic outcome of joint replacement surgery is a common and popular process under the territory of joint registries in many countries. in this article we introduce the methodology used for the foundation of the national iranian joint registry (ijr) with a joint collaboration of the social security organization (sso) and academic research depar...

The success of total knee arthroplasty depends in part on proper soft tissue management to achieve a stable joint. It is unknown to what degree total knee arthroplasty changes joint stability. We used a surgical navigation system to intraoperatively measure joint stability in 24 patients under going primary total knee arthroplasty to address two questions: (1) Is the total arc of varus-valgus m...

Total knee arthroplasty is a successful procedure to treat pain and functional disability due to osteoarthritis. However, precisely how a total knee arthroplasty changes the kinematics of an osteoarthritic knee is unknown. We used a surgical navigation system to measure normal passive kinematics from 7 embalmed cadaver lower extremities and in vivo intraoperative passive kinematics on 17 patien...
