The Maquet procedure in the treatment of patellofemoral osteoarthrosis. Long-term results.

Long-term results are reported for 35 knees with patellofemoral osteoarthrosis treated by Maquet procedure. Eighty percent were rated very good or good, and 20% fair or poor. The poor results are attributed to errors in the diagnosis or to inadequate surgical technique. The Maquet procedure thus provides good results for painful knees with patellofemoral osteoarthrosis. A tibial tubercle elevation of at least 2 cm is necessary to decrease joint pressure sufficiently.
