The effect of lateral retinacular release in idiopathic chondromalacia patellae.

The results of lateral retinacular release were evaluated in 28 patients with idiopathic chondromalacia patellae. Follow-up was performed 3-5 years after the operation. At follow-up 13 patients were improved, while the symptoms were equal or intensified in 15 patients. However, compared with the situation before the operation, the levels of activity were increased in only two patients, while the levels of activity were unchanged or reduced in the remaining 26 patients. From this study it is concluded that the results of lateral retinacular release for idiopathic chondromalacia patellae are poor with regard to relief of symptoms, and especially with regard to improvement in ability to perform physical activities.
