Objective The purpose of this study was to evaluate the clinical and functional results of surgical treatment for patellar subluxation. Methods A retrospective study was undertaken between O ctober 2004 and A pril 2009 of 78 cases of patellar subluxation: 40 cases with medial capsule reefing, of which 15 cases had the combination of lateral retinacular release ( G roup A ); and 38 cases with medial patellar retinaculum plasty, of which 12 cases had the combination of lateral retinacular release ( G roup B ). All patients had CT scans available for reviewing congruence angle ( CA ) with knee flexion at 30 degrees. In addition, knee function was evaluated using the K ujala score and subjective questionnaires. Results Patients were followed up for a mean 60 months (33–87 months). The K ujala score improved significantly from 78.3 ± 1.0 to 88.3 ± 1.6 in G roup A and from 77.8 ± 0.9 to 91.2 ± 1.7 in G roup B ( P < 0.05). Postoperatively, the CA on CT scan had a statistical difference between the two groups ( P < 0.05). The subjective questionnaire revealed a significant difference ( P < 0.05), including 12 excellent, 20 good and eight fair in G roup A , and 25 excellent, and 13 good in G roup B . Conclusion The medial retinaculum plasty was better than medial capsule reefing in improving the subjective effects and decreasing the patellar subluxation rate.
