Posterior stabilised implants are a well-proven treatment for patients requiring primary total knee arthroplasty. Concerns about the posterior stabilised (PS) design have been raised and recent studies suggest that the post-cam articulation can be an additional source of polyethylene wear debris. In this study, the authors report impingement of the tibial post against the patellar component in ...

BACKGROUND Evidence regarding the risk of end-stage osteoarthritis following cruciate ligament reconstruction is based upon small sample sizes and radiographic, rather than clinical, criteria. The goals of this study were to determine the risk of knee arthroplasty, a surrogate for end-stage osteoarthritis, following cruciate ligament reconstruction, and to identify patient, provider, and surgic...

primary knee osteoarthritis (oa) is one of the degenerative diseases that destroy auricular cartilage within knee joint and cause pain, varies deformity, decrease knee function. total knee arthroplasty (tka) is an effective intervention in order to relieve pain, improve function and qol (quality of life) in patients with severe osteoarthritis of the knees that have different degrees of varus de...

Total knee arthroplasty is a successful operation that significantly improves patient's quality of life. However, studies demonstrated as only 82% to 89% of patients are satisfied with their surgery, being the other disappointed with regard to their expectations. Two to 5.7% of total knee arthroplasties (TKAs) require revision within 5 years. Both complex primary cases and revision TKA often ne...

Objective To evaluate the difference between the total blood loss in patients undergoing primary total knee arthroplasty with and without the use of tourniquet. Methods A retrospective cohort study, with analysis of medical records of patients undergoing primary total knee arthroplasty in 2015, with and without the use of a tourniquet. Comparison was performed of hemoglobin (HB) and hematocri...

Few studies quantitate the cost of a quality well being as produced by arthroplasty surgery. The objective was to use the Quality of Well Being Index to calculate the cost per quality of well year in knee arthroplasty surgery. The difference in Quality of Well Being Index scores before and after the intervention was calculated and multiplied by the patient's life expectancy. The procedure cost ...

background: total knee arthroplasty is a complex procedure aiming to relieve pain and improve function. it is critical to select prosthesis that best cover the bone surfaces. ethnicity may affect fitness of the components mainly designed for caucasian populations. this study aimed to evaluate morphometric features of proximal tibia in iranian population.   methods : during 2013, 150 consecutive...
