Failure after total knee arthroplasty (TKA) may be related to emerging technologies, surgical techniques, and changing patient demographics. Over the past decade, TKA use in Korea has increased substantially, demographic trends have diverged from those of Western countries, but failure mechanisms not been well studied.We determined causes TKA, risk factors for failure, revision TKAs over last 5 years.We retrospectively reviewed 634 20,234 primary performed at 19 institutes affiliated with...
For articular cartilage defect treatment, many treatment modalities have been developed. We evaluate the repair potential of an atelocollagen and fibrin mixture transplanted to defects. A circular, 4 mm in diameter was made trochlear region each 20 New Zealand white rabbits. The 10 rabbits control group were kept without experimental underwent injection mixed with fibrin. At week 12 following surgery observed histologically compared both groups. surface newly generated very smooth even, we...
We evaluated the bone-forming potential of a mixture atelocollagen and bone marrow aspirate concentrate which was transplanted into defects. Radial shaft defects about 10 mm in size were created 30 New Zealand white rabbits. Ten rabbits control group not treated further, first experimental (E1) received an injection, second (E2) injection concentrate. The groups compared radiologically at 8 weeks. Osteogenesis E2 progressed more rapidly than that other groups, osteogenesis E1 faster group....
High fibular osteotomy (HFO) is a simple surgical technique to reduce pain and improve function in patients with osteoarthritis via osteotomy. We report short-term results of HFO mesenchymal cell induced chondrogenesis (MCIC) for the treatment knee varus deformity.45 symptomatic 14 males 31 females age ranging from 40 75 years were treated by MCIC. Main lesions involved medial compartment lateral normal mild meniscus articular cartilage, amenable partial meniscectomy or observation.Knee...
Purpose: To analyze the clinical results of transverse Kirschner (K)-wire fixation for metacarpal fractures. Materials and Methods: Between May 2002 2005, thirty-four cases (thirty-nine fingers) unstable fractures underwent a closed reduction K-wire fixation. The neck, shaft base metacarpals except thumb were included. follow-up period ranged from 12 months to 3 years 4 (mean; 2 1 month). Interfragmentary was performed on 24 cases. A short arm splint maintained until postoperative weeks,...
Purpose: To determine the necessity of an additional posterior lumbar interbody fusion (PLIF) after a posterolateral (PLF) for treatment degenerative spondylolisthesis (DS). Materials and Methods: A retrospective study, minimum follow-up 2 years was conducted on forty patients who underwent single level decompression instrumented DS with spinal stenosis at L4-5 level. PLF performed in 21 patients, circumferential (CF) PLIF 19 patients. According to methods preoperative segmental mobility,...
Purpose: To investigate the effect of lateral buttress on fracture healing Jensen type 4 intertrochanteric femur treated by dynamic compression hip screw (DCS) in elderly patients, retrospectively. Materials and Methods: From March 1999 to February 2003, 54 older than 65 years, fractures DCS were included. The relationship between structual integrity measured proximal-medial fragment angle (PMFA) postoperative neck-shaft angle, penetrating length lag screw, sliding incidence fixation loss...
Purpose : To identify sensory nerve endings in the human hip joint capsule and pseudocapsule after total replacement. Materials Methods Ten capsules from patients undergoing bipolar replacement for acute femoral neck frac-ture, six pseudocapsules revision surgery failed were harvested stained bulk using a modified gold-chloride method. Sensory identified criteria described by Freeman Wyke. Results Three morphologically distinct types of normal capsules; type I Ruffini corpuscles, II Pacinian...
Purpose : To evaluate the efficacy of arthroscopic synovectomy through direct posteriorposterior approach in pigmented villonodular synovitis (PVNS) knee. Materials and Methods Between January 1997 May 2004, twenty-one patients underwent an for PVNS The mean follow-up period was 35 months. MRI findings revealed localized form six diffuse fifteen patients. All examination posterior-posterior approach. clinical results were evaluated by range motion, Lysholm knee score, pain score using visual...
