[Arthroscopic reconstruction of anterior cruciate ligament of knee by using autologous multi-stranded semitendinous tendon].
OBJECTIVE
To explore the therapeutic efficacy of arthroscopic reconstruction of anterior cruciate ligament (ACL) with autologous multi-stranded semitendinous tendon (ST).


METHODS
From September 2000 to December 2004, 50 cases of ruptures of ACLs were diagnosed by clinical and arthroscopic examinations. There were 32 males and 18 females with an average age of 26.3 years (18-51 years). The locations were left knee in 31 cases and right knee in 19 cases. All patients had the history of knee joint injury. Arthroscopy showed 26 cases of rupture, 14 cases of defect, 4 cases of avulsion and 6 cases of laceration. All patients were operated upon arthroscopically by using autologous multi-stranded ST. Plaster splints were used for 4 weeks after operation. The result was estimated by AO Yingfang's standards and Lysholm knee scores.


RESULTS
All patients achieved healing by the first intention. The extension and flexion function was restored normal at 8-10 weeks. The patients were followed up averagely 1 year and 8 months (6-48 months). The results of drawer test and Lachman test were positive in 3 cases and suspiciously positive in 8 cases. The results were excellent in 23 patients, good in 18 and fair in 9. Lysholm knee scores were 40.57+/-10.68 preoperatively and 86.43+/-9.33 postoperatively, showing significant difference (P < 0.01).


CONCLUSIONS
Arthroscopy reconstruction of ACL with autologous multi-stranded ST may be one of the excellent methods bringing less injury.
