title: [Patellectomy with preservation of the leverage and continuity of the extensor system in patellar chondropathy].
abstract: Seventy patellectomies have been performed using an original technique which aims to replace the site of the patella by two cross bands of fibrous tissue derived from the lateral and medial ligaments. This technique preserves the continuity of the extensor mechanism and it allows early mobilisation with shortening of post-operative rehabilitation time. It causes the tendon to thicken, improves cosmesis and maintains the force of the quadriceps, the tendon being kept forward by conservation of the infra-patellar fat pad. The results have been studied in 41 cases of patellar chondropathy, since the results are usually worse in this type of lesion especially in younger patients whose activity is greater. Pain was abolished in 28 cases. The range of movement and quadriceps power was good in all cases but two. In the absence of complications the final result was obtained after 4 months in cases of primary patellectomy. Failures were related to 9 early and 5 late complications. The results were better when the patellectomy was primary and were made worse by any previous surgical procedures.
