The position of the fibula around proximal tibia varies in different people; it was therefore hypothesized that this variation would affect orientation lateral collateral ligament and popliteofibular complex. This hypothesis studied 10 cadaveric knees by measuring length changes these structures as knee flexed. data were correlated with tibiofibular joint position. strength ligaments also tested. There significant correlations between fibular head extended. slackened significantly flexion,...
The histologic findings of osteochondritis dissecans the knee vary widely, leading to differences in interpretation its origins. Hypothesis might represent a course pathologic progression.Descriptive laboratory study.Twelve knees 11 patients (average age, 16 years) with medial femoral condyle were treated by biological internal fixation. During surgery, cylinder osteochondral plugs taken from center lesion and examined light microscopy.A complete or partial cleft separated specimens into 2...
The macroscopic and histologic findings for 31 medial menisci tibial plateaus obtained during total knee arthroplasty were examined to clarify the etiology progression of varus osteoarthritis. Medial preserved fairly well in cases severe osteoarthritis which joint space had already disappeared. anterior segment was 26 (84%) posterior 11 (35%). meniscus may have been because its radial displacement. Exposure subchondral bone plateau occurred all knees. exposure centered anterior, middle,...
Four knees in three patients with traumatic separation of a Type I bipartite patella are reported. Sudden anterior knee pain and an audible pop occurred at the time injury had aching or dull before episode. Previous led us to differentiate this type from usual transverse fracture. A round fracture line seen on radiographs also stress Accordingly, diagnosis was confirmed. This is first report our knowledge.
It is well known that anterior cruciate ligament (ACL) injuries are commoner in female athletes. Accordingly, we hypothesized serum estrogen may play some role this sex difference. We evaluated the relationship between levels and mechanical properties of ACL rabbits.In 40 ovariectomized rabbits, (SEL) were controlled by intramuscular injection 17beta-estradiol. The mean SEL each rabbit was defined as average 5 determinations done at 1, 2, 3, 4 weeks after ovariectomy. animals divided into...
To evaluate the outcome of autologous morselised bone grafting for a medial tibial defect ≥10 mm deep in 45 total knee arthroplasties (TKAs).38 patients aged 46 to 85 (mean, 73) years underwent TKAs and (range, 10-25) depth by single surgeon. In first 19 TKAs, 2 resected subchondral plates from lateral plateau were driven into gutters made on floor as bony support posts. Morselised cancellous grafts then impacted around these remaining 26 multiple drill holes decrease remodelling time. fill...
We report the second case of osteochondritis dissecans (OCD) knee in identical twins (bilaterally one and unilaterally other). Fixations with bio-absorbable pins, cylindrical osteochondral graft, mosaicplasty were all successful bone union was achieved. considered that genetic factors remain essential even if other (particularly repetitive trauma) are mainly responsible for occurrence OCD.
Five patients with pigmented villonodular synovitis of the knee associated lesions posterior periarticular bursae were treated by exploration, excision bursal tissue, and routine anterior synovectomy knee. It was hypothesized that complete would reduce high recurrence rate To completely excise lesions, two oblique skin incisions used. In all patients, seen clearly on computed tomography scans after air arthrography magnetic resonance imaging scans. The followed up for 6.9 years average...
