Abstract:
[Objective]The patellar tendon lengths were compared in the knees with a history of patellar instability and in normal knees in Chinese,and the significance of patellar tendon length measurement in the knees of patellar instability was discussed.[Method]Totally 49 knees of 43 patients with patellar instability were reviewed from Jan.2003 to Dec.2005,including 15 males and 28 females and 6 paients with both instahle patellas.The mean age was 21.4 yrs(from 18~28 yrs),and the mean height was 163 cm(155~173 cm).And,50 normal control knees of 50 volunteers including 16 males and 34 females.The mean age was 24.2 yrs(from 18~35 yrs),and the mean height was 165cm(154~177 cm).The patellar tendon length,the distance between tibial tubercle and the anterior edge of tibial plateau and Insall-Salvati index on the lateral X-ray plain with 30? flexion of keens were measured and analyzed.[Result]The patellas tendon length of patients was longer than that of normal volunteers(53.3?2.7mm,47.3?3.3 mm,P0.05)of the distance from tibial tubercle to the anterior edge of tibial plateau between patients and volunteers.However,difference of Insall-Salvati index between patients and volunteers was significant(1.33?0.17,1.06?0.14,P
