BACKGROUND This meta-analysis (MA) aims at comparing the clinical outcomes of resurfacing and nonresurfacing the patella in patients undergoing total knee arthroplasty in the treatment of knee osteoarthritis. METHODS Randomized controlled trials were included by retrieving data from electronic English databases. Both fixed and random-effects models were employed, and standardized mean differe...

PURPOSE The Korean Knee score (KKS) was designed to reflect the floor-sitting lifestyle that necessitates high knee flexion. The purpose of this study is to assess whether the KKS reflects the floor-sitting lifestyle more accurately than the previously developed Knee Society clinical rating system. In addition, the presence of ceiling effects was compared between the two rating systems. MATER...

PURPOSE Studies report 19-33% postoperative moderate-severe pain and dissatisfaction in uncomplicated total knee arthroplasty (TKA), even after 1 year. High rates of undiagnosed depression and anxiety may have a strong impact on these unfavourable outcomes. Here we aimed to investigate the efficacy of alprazolam on postoperative analgesic use and knee functions. METHODS Seventy-six patients w...

 Abstract  Background: In the recent decade, many primary total knee arthroplasties have  been carried out in Iran and the number of revision cases is expected to rise with the  aging population. The aim of this study was to report the outcome of revision surgery  in the country and make a comparison between the outcome of revision and that of  the primary arthroplasty.  Methods: Retrospectivel...

Date of acceptance / Kabul tarihi: March 15, 2016 / 15 Mart 2016 ABSTRACT: Midterm clinical and radiological outcomes of total knee arthroplasty Purpose: The aim of this study is to investigate retrospectively the midterm clinical and radiological outcomes of total knee arthroplasty (TKA) which were performed in our clinic.

Between 1998 and 2002, 25 patients who were treated with a refrigerated or frozen allograft were evaluated. The mean patient age was 48 years. The mean lesion size was 4.5 cm. Validated outcome instruments [Knee Society Score, Western Ontario and McMaster University Score] were used. Clinical and radiographic evaluations were performed pre-operatively and at the most recent follow-up. Histologi...

Patellar resurfacing in total knee arthroplasty (TKA) remains controversial. This study evaluates the results of resurfacing and non-resurfacing of the patella. Fifty-six patients with osteoarthritis (OA) of the knee were enrolled in a prospective randomised clinical trial using a posterior-stabilised TKA. Evaluations were done preoperatively and after 1, 3, 6, 12 and 24 months. Disease specifi...

PURPOSE To compare clinical outcome of revision total knee arthroplasty (TKA) between the infected and non-infected groups. MATERIALS AND METHODS This study compared the clinical and radiographic results of 21 infected and 15 non-infected revision TKAs at a minimum 2-years follow-up. Clinical evaluations were assessed using the range of motion (ROM), Hospital for Special Surgery (HSS) score, ...

PURPOSE To evaluate the tibial articular cartilage and histology of the posterior cruciate ligament (PCL) in osteoarthritic knees so as to determine predictors of PCL degeneration. METHODS 23 advanced osteoarthritic knees (mean patient age, 61 years) treated with total knee arthroplasty (TKA) were prospectively studied. The Knee Society Score was assessed. Osteoarthritic changes on radiograph...
