PURPOSE Several analgesic techniques are available for pain management after a major operation. MATERIALS AND METHODS From December 2005 to February 2006, a prospective, double-blind study was performed involving 90 patients who had undergone a total knee arthroplasty. Patients were randomly divided into three equal groups (n=30). Demographic data,(More)
STUDY DESIGN A prospective case control study. OBJECTIVES To investigate the risk of a fall by using functional mobility tests in patients with lumbar spinal stenosis (LSS) via a comparison with patients with knee osteoarthritis (KOA). SUMMARY OF BACKGROUND DATA LSS is a degenerative arthritic disease in the spine that results in decreasing function,(More)
The aim of this retrospective study was to compare clinical outcomes of total knee arthroplasty (TKA) with and without patellar resurfacing using the Low Contact Stress (LCS) mobile-bearing prosthesis in 275 osteoarthritic knees (199 patients) after a minimum of 7 years of follow-up. Patients were divided into a patellar retention group (132 knees) and a(More)
ETHNOPHARMACOLOGICAL RELEVANCE This prospective, randomized, double-blind, multicenter study compared the efficacy and safety of Celecoxib and GCSB-5, a new product from extracts of six herbs, for the treatment of knee osteoarthritis. MATERIALS AND METHODS A total of 198 eligible patients were randomly assigned to the Celecoxib group (n=99 patients) or(More)
PURPOSE To evaluate the minimum 5-year mid-term clinical and radiological results of minimally invasive surgery total knee arthroplasty (MIS-TKA) using a mini-keel modular tibia component. MATERIALS AND METHODS We retrospectively evaluated 254 patients (361 cases) who underwent MIS-TKA between 2005 and 2006. The latest clinical and radiological(More)
Purpose This study aims to identify the effectiveness of the medial cortical line for attaining a more accurate tibial component alignment in proximal tibial resection using an extramedullary alignment rod. Materials and Methods The study examined 100 cases of total knee arthroplasty performed from December 2013 to February 2014 in a retrospective manner.(More)
We compared bilateral total knee arthroplasty (TKA) performed at a single session vs those performed at 2 separate sessions with respect to complications, amount of blood loss, and length of hospital stay. Study participants included 119 consecutive patients undergoing simultaneous bilateral TKA and an additional 119 patients undergoing staged bilateral(More)
PURPOSE The aim of this study was to report the long-term outcome and the failure mechanism of cementless total hip arthroplasty (THA) using hydroxyapatite (HA)-coated acetabular cup. MATERIALS AND METHODS From January 1992 to May 1994, a total of 123 consecutive cementless primary THAs were performed using a HA-coated acetabular cup with(More)
The aim of this study was to evaluate complications related to prosthesis design in patients managed with cemented total knee arthroplasty using anterior-posterior glide mobile-bearing prosthesis. One hundred eighty-three total knee arthroplasties were performed using this prosthesis on 146 patients, with a minimum of 7 years of follow-up. There were late(More)
This is a cross-sectional observational study undertaken to explore the current prescription pattern of non-steroidal anti-inflammatory drugs (NSAIDs) and the prevalence of NSAID-induced gastrointestinal (GI) risk factors of orthopaedic patients in real clinical practice in Korea. Study cohort included 3,140 orthopaedic outpatients at 131 hospitals and(More)
