Clinical Course and Roentgenographic Changes of Osteonecrosis in the Femoral Condyle Under Conservative Treatment

Effectiveness of an insole with a lateral wedge for idiopathic osteonecrosis of the knee

“…The incidence of osteoarthritis after conservative treatment ranges from 33% to 90%. 9,22,23 Our results showed a similar prevalence of osteoarthritis (stage 4; 54%) in group II. We hoped that the use of an insole might give lasting symptomatic relief.…”

“…2,[11][12][13][14][15][16][17][18][19][20][21] There are only a few reports on the natural history after conservative treatment. 9,22,23 Physiotherapy, analgesics and anti-inflammatory medication do not alter the radiological outcome, despite sometimes giving symptomatic relief.…”

MRI evaluation of steroid- or alcohol-related osteonecrosis of the femoral condyle

“…There have been many case reports about steroid-or alcohol-related osteonecrosis of the femoral condyle (Dubois and Cozen 1960, Hall and Hume 1970, Ishkhanian and Ramsey 1977, Isono et al 1987, Have1 et al 1989, Kelman et al 1990, Healy 1991, Motohashi et al 1991, Ochi et al 1995, but the natural history and best treatment are still unknown. In our study, lateral condyles tended to be affected and both condyles were mainly involved, as Chancelier et al (1992) claimed, in steroid-related osteonecrosis.…”

“…Since 2 patients were reported by Dubois and Cozen (1960) in a series of 400 cases of systemic lupus erythematosus, steroid-or alcohol-related osteonecrosis of the femoral condyle has been sporadically reported (Isono et al 1987, Bohn et al 1989, Have1 et al 1989, Kelman et al 1990, Motohashi et al 1991, Ochi et al 1995. Condyles with minimum clinical symptoms may progress to collapse and generate osteocartilaginous fragments (Hall andHume 1970, Ishkhanian andRamsey 1977), needing surgical treatment.…”

MR Imaging of Epiphyseal Lesions of the Knee: Current Concepts, Challenges, and Controversies

“…The pace of disease progression depends on its location and size. Small lesions (< 3.5 cm 2 ) may be well tolerated for several years, whereas extensive lesions with subchondral bone plate fracture result in severe persisting complaints and functional joint impairment [9,43,44].…”
