Well-balanced charge of femoral and tibial cartilage by lateral transfer of the mechanical leg axis in osteoarthritis of the medial compartment and of genu varum. ⋯ Between January 2006 and December 2008, procedure performed in 50 patients (27 men, 23 women, mean age 44 years); arthroscopic treatment in 43 patients, and osteotomy of the fibula in 10 patients. The valgus correction was 8.4° (6-13°). No complication during surgery. One non-union was treated by cancellous bone grafting.

[Modular reconstruction in acetabular revision with antiprotrusio cages and metal augments : the cage-and-augment system].
Restore primary center of rotation and reconstruct extensive bone defects in hip revision surgery with a modular off-label implant combined with antiprotrusion cage and metal augment, thus, achieving improved hip function. ⋯ Since 2008, 72 off-label implantations of a combined antiprotrusio cage and a Trabecular Metal™ Augment were performed. A total of 44 patients (46 operations) were investigated at 38.8 (36-51) months postoperatively. In all, 36 patients had a bone defect according to Paprosky type 3a/b and in 3/4 patients with pelvic discontinuity additional osteosynthesis was performed. The WOMAC score increased from 39.8 (8.7-75) points preoperatively to 57.9 (16.7-97.9) points at follow-up. Migration or failure of implant components was not observed. In 11 % of dislocations and 11 % periprosthetic infections surgical revision was necessary.
