Abstract:

Objective To investigate the therapeutic effects of arthroscopic medial retinacular reefing and lateral retinacular release for patellar dislocation.   Methods   From March, 2009 to July, 2011, 25 patients of patellar dislocations were treated by arthroscopic medial retinacular reefing and lateral retinacular release. All patients accepted regular rehabilitation training and were followed up for 20 months in average (18 to 24 months). The rate of recurrence,the subjective symptoms and the function of the injured leg were evaluated according to the Lysholm score. X-ray examination was taken to evaluate the patella-femur congruence and the lateral patella angle.    Results    The patellar stability was restored in all patients,and no recurrence of patellar dislocation was found within follow-up. The Lysholm scores were(59.00±13.37)and(92.14±5.15)(P<0.05)before and after surgery respectively. X-ray examination showed that patella-femur congruence angle improved from(21.10±5.61)° to(-1.70±7.41)°(P<0.05), and the lateral patella angle from(-1.3±1.6)° to(6.1±1.4)° (P<0.05) in average. The three indicators compared before and after surgery had significantly statistic differences.   Conclusion     Arthroscopic medial retinacular reefing and lateral retinacular release for patellar dislocations is effective and minimally invasive.
