BACKGROUND Mobile-bearing knee designs represent an alternative to conventional fixed-bearing implants in total knee arthroplasty. The purpose of this study was to determine the clinical results of a mobile-bearing knee implant. METHODS From 1990 to 1998, 326 primary consecutive mobile-bearing total knee prostheses were implanted in 260 patients who had a mean age and standard deviation of 66...

PURPOSE To analyze minimum 2-year clinical and radiological follow-up results of primary total knee replacement arthroplasty (TKRA) with metal block augmentation for tibial bony defect. MATERIALS AND METHODS We analyzed 67 cases (52 patients) of primary TKRA with metal block augmentation for tibial bony defects from March 1999 and March 2008. Clinical results were evaluated using the Knee Soc...

PURPOSE To compare outcomes in Indian women who underwent total knee arthroplasty (TKA) using the standard Legacy Posterior Stabilised (LPS) versus the gender-specific LPS high-flexion knee prosthesis. METHODS 100 women (200 knees) aged 60 to 80 years with an arc of flexion of ≥90º underwent simultaneous sequential TKA for primary osteoarthritis of both knees. They were randomised to receive ...

PURPOSE To evaluate clinical results of two-stage revision using a modified articulating spacer for treatment of infected total knee arthroplasty (TKA). MATERIALS AND METHODS We retrospectively reviewed 20 cases treated by two-stage revision arthroplasty using a modified articulating spacer under the diagnosis of infected TKA from January 2006 to December 2011. The mean follow-up period was 2...

BACKGROUND Clinical and radiologic evaluation and analyses of the surgeries using Buechel and Pappas (B-P) knee implants. METHODS The study was conducted on 60 patients who underwent 94 total knee replacement arthroplasty with B-P knee implants from May 2009 to December 2010. The results were compared to the results of 41 patients who underwent 60 knee joint surgeries using NexGen-LPS implant...

PURPOSE To identify factors related to knee flexion after total knee arthroplasty in a Chinese population. METHODS Records of 242 total knee arthroplasties were retrospectively reviewed. The parameters evaluated were age, gender, diagnosis, preoperative knee flexion and extension, preoperative flexion arc, tibiofemoral angle, Knee Society knee score and functional score, and implant design. ...

OBJECTIVES The objective of this study was to compare the early migration characteristics and functional outcome of the Triathlon cemented knee prosthesis with its predecessor, the Duracon cemented knee prosthesis (both Stryker). METHODS A total 60 patients were prospectively randomised and tibial component migration was measured by radiostereometric analysis (RSA) at three months, one year a...

background: articular cartilage injuries are a common clinical problem at the time of acl reconstruction with an incidence rate of 16-46%. good results of acl reconstruction combined with the treatment of chondral lesions have been published in some studies. method: after statistical analysis 30 patients were selected and divided in 2 groups. theffirst group consisted of 15 patients wite isolat...

BACKGROUND Unicondylar knee arthroplasty (UKA) is a well-established treatment for isolated osteoarthritis (OA) of the medial knee compartment. Aim of this retrospective study was to evaluate the early clinical and radiological outcomes of a consecutive series of patients treated with medial metal backed fixed-bearing UKA. Furthermore, the influence of the component orientation on the outcome w...

BACKGROUND AND PURPOSE Pain sensitization may be one of the reasons for persistent pain after technically successful joint replacement. We analyzed how pain sensitization, as measured by quantitative sensory testing, relates preoperatively to joint function in patients with osteoarthritis (OA) scheduled for joint replacement. PATIENTS AND METHODS We included 50 patients with knee OA and 49 wi...
