Arthroscopic Four-stranded Semitendinosus Anterior Cruciate Ligament Reconstruction Methods Discussed

Purpose: To explore more than arthroscopic hamstring tendon suspension buttonmini-plate fixation of anterior cruciate ligament reconstruction of the surgical methods and clinical efficacy.Material and method: From December 2007 to June 2008, 48 cases of rupturesof ACLs were diagnosed by clinical and arthroscopic examinations. There were 34 males and 14 females with an average age of 26.3 years(19～49 years). The locations were left knee in 30 cases and right knee in 18 cases. Exercise-induced injury of which 26 cases, 19 cases of car accident injury, 3 cases of other injuries. All patients had the history of knee joint injury. The basis of clinical performance and MRI diagnosis of anterior cruciate ligament injury in 31 cases, with arthroscopic examination and surgery alone anterior cruciate ligament confirmed 16 cases of injury . "Triad" that is, the combined anterior cruciate ligament medial collateral ligament, 10 cases of medial meniscus injury . Combined two cases of lateral structural damage. 5 cases of lateral meniscus injury combined. Injury to surgery 2 weeks to 22 months . Arthroscopy of anterior cruciate ligament body of 25 cases of fracture, ligament absence of eight cases, femoral avulsion only 15 cases of point . Body from the semitendinosus muscle, gracilis tendon, multi-unit arthroscopic hamstring tendon isometric anterior cruciate ligament reconstruction, using mini-plate end femur, tibia client using buttons fixed suspension . The result Was estimated by AoYingfang's standards and Lysholm knee scores.Results: ALL patients achieved healing by the first intention. Knee extensionand flexion function was restored normal at 8～10 weeks. The patients were followed up averagely 1 year (6～14 months). Two cases of intense exercise a sense of pain after knee surgery; 1 cases of obvious improvement in symptoms. Follow-up drawer and Lachman tests positive test three cases, six cases of suspicious positive, more patients were negative. 6 cases of suspected positive patients have 3 cases of knee instability in a sense of movement, and the remaining three cases does not did not appeal. Range of motion: 0°～130°43 cases, 0°～100°5 cases. Or mitigate the original symptoms. Subjective evaluation of knee function improved the treatment results were satisfactory. Lysholm knee scoring method used to assess post-operative score of 87.21±8.57, compared with the preoperative differences were significant (P<0.01). Ao Yingfang reference standards for clinical diagnosis: The 23 cases were excellent, good in 18 cases, average in 4 cases and poor in 3 cases.Conclusion: Arthroscopic multi-autologous hamstring tendons anterior cruciate ligament reconstruction has the following advantages: the ideal graft material; anatomy isometric reconstruction; fixed firmly in force; convenience, less injury.
