Between 2003 and 2007, 99 knees in 77 patients
underwent opening wedge high tibial osteotomy. We evaluated the effect
of initial stable fixation combined with an artificial bone substitute
on the mid- to long-term outcome after medial opening-wedge high
tibial osteotomy (HTO) for medial compartmental osteoarthritis or
spontaneous osteonecrosis of the knee in 78 knees in 64 patients
available for review at a minimum of five years (mean age 68 years;
49 to 82). The mean follow-up was 6.5 years (5 to 10). The mean
Knee Society knee score and function score improved from 49.6 ( Opening-wedge HTO using a stable plate fixation system combined
with a bone substitute is a reliable procedure that provides excellent
results. Although this treatment might seem challenging for older
patients, our results strongly suggest that the results are equally
good. Cite this article:
Fracture repair occurs by two broad mechanisms:
direct healing, and indirect healing with callus formation. The effects
of bisphosphonates on fracture repair have been assessed only in
models of indirect fracture healing. A rodent model of
We treated 19 patients with established nonunion of the radius and/or ulna by the excision of avascular bone and the grafting of blocks of corticocancellous bone from the iliac crest, augmented by
We used dual-energy X-ray absorptiometry (DEXA) to measure the bone mineral content (BMC) of both tibiae in 13 patients who had been treated for a tibial fracture by
