胫骨结节抬高内移治疗髌骨软化症(附25例分析)

Objective To analyse the therapeutic basis and effect on the treatment for chondromalacla patellae (CP) by elevation and interior transmigration of tubercles of tibia. Methods 32 tubercle of tibia from 25 cases with CP were treated with forward--interior transmigration(l. scm) along an angle of 45° and the theraputic effect was reviewed and analysed. Results 32 knee joints from 25 cases were treated by elevation and Interior tranmigration of tubercle of tibia and a follow--up survey of 1-5 years showed that of all the 32 knee joints treated,21 were excellent(65. 63% ), 9 good(28. 12% ) and 2 passable without any failure. The fine rate was 93. 75 st with 100% of effective rate. Conclusion Treatment for CP by elevation and interior transmigration of tubercle of tibia would simultaneously reduce the contact pressure on patellar ]olnt, regulate the Q angle, loosen the lateral tissue of the patella,and remove the main pathogenic factors of CP,and therefore the treatment is obviously superior to any other methods.
