The intraosseous pressure in the femur and tibia near the knee and in the internal saphenous vein at knee level was measured in fifty-three patients with suspected knee lesions. There were four groups: with and without degenerative osteoarthritis and with and without aching rest pain of the knee region. Low intraosseous pressures were found in patients with(More)
Twenty-five patients with pain in the knee or hip were examined by means of bilateral intraosseous phlebography, intraosseous pressure measurements and 99mTechnetium polyphosphate scintigraphy. All patients with typical rest pain--either due to osteoarthritis or to the intraosseous engorgement-pain syndrome--showed venous stasis and increased pressure in(More)
A multivariate regression analysis of survival data, using the Cox proportional hazards model (PHM), was performed on the retrospective material of 184 osteosarcoma patients treated at the Aarhus and Copenhagen oncology centers, Denmark, from 1963 to 1984. All patients were previously untreated. Radical surgery, in general ablative when possible, was the(More)
In 40 patients with patellofemoral pain, intra-osseous pressure measurements were recorded under anaesthesia with the knee first in extension and then in flexion prior to performing a longitudinal osteotomy of the patella. There was a statistically significant increase of pressure in painful knees compared with normal knees (29 mm Hg. vs 15 mm Hg.), and a(More)
