[Treatment of patello-femoral arthrosis by anterior displacement of the tibial tuberosity (Maquet procedure)].

The authors have treated 71 cases of patello-femoral arthrosis by anterior displacement of the tibial tuberosity to diminish pressure of the patella. In most cases, an osteotomy of the tibial crest was made and forward displacement maintained by the addition of a bone graft. The medial and lateral patellar retinacula were divided, the patellar articular cartilage was shaved and fine drill holes made in chondromalacic cartilage. The results were satisfactory in 75% of cases but the follow-up was short (about one year). It was concluded that the tibial tuberosity should be displaced forward by about 2 centimetres. The surgical technique is fully described.
