Abstract:

BACKGROUND: Excessive lateral pressure syndrome is often associated with lateral retinacular tension and radiographic patellar tilt. CT scan displayed that lateral retinacular release can effectively correct patellar tilt.
OBJECTIVE: To study the effect of arthroscopic lateral retinacular release combined with intraosseous drilling and decomposition in the treatment of excessive lateral pressure syndrome.
METHODS: Thirty-two patients with excessive lateral pressure syndrome were treated by arthroscopic lateral release combined with intraosseous drilling and decomposition. The Lysholm scoring system was used to evaluate the treatment effect.
RESULTS AND CONCLUSION: The mean duration of follow-up was 12 months. After 1 month, pain of all patients was released or disappeared; after 1 year, pain of 26 cases disappeared basically. Lysholm scoring system assessment showed 20 cases were rated as excellent, six cases were as good, four cases were as fair and two cases were as poor. The excellent and good rate was 83.6%. The patients’ subjective satisfaction rate was 92.8%. The results indicate that arthroscopic lateral release combined with intraosseous drilling and decomposition is a good method to treat excessive lateral pressure syndromewere. It has the advantages of less trauma and rapid recovery. Patellar decomposition has a good effect in the treatment of patellofemoral pain associated with patellar tilt outward and lightens articular cartilage degeneration without damage to patellar cartilage surface.
