Experience with Maquet anterior tibial tubercle advancement for patellofemoral arthralgia.

The Maquet tibial tubercle advancement osteotomy was performed in 9 knees (8 patients) for patellofemoral arthralgia, including both "chondromalacia patella" and patellofemoral arthritis. The longest follow-up was 72 months, the shortest was 13 months with an average of 29 months. The results were excellent in 6, good in one and fair in one. There were 3 minor complications. The advantages of this procedure are its effectiveness and predictability in relief of symptoms, the preservation of the patella (thereby not prejudicing further procedures if necessary), and the surgery is extra-articular.
