Abstract:

Objective According to the analysis of the knee function and the stability, the postoperative efficacy of the anterior cruciate ligament(ACL) reconstruction with residual preservation was evaluated and the clinic role of residual preservation was explored. Methods From January 2011 to January 2013,78 cases of patients diagnosed with the anterior cruciate ligament rupture underwent ACL reconstruction with allogeneic hamstring tendons, and all patients were followed up for at least 12 months. Of  the 78 cases , there were 51 males and 27 females with an average age of 29.2 years old. The average interval from injury tosurgery was 3 months; All 78 cases of patients had complete rupture of the anterior cruciate ligament, including 30 cases of body rupture, 44 cases of femoral attachment point rupture and 4 cases of tibial attachment point rupture. Surgery was performed in a way that could retain the remaining stump as much as possible. The postoperative knee function and stability were followed up for a period of 12~35 months with an average of 25 months. The clinic effects were evaluated according to the physical examination.    Results    Lachmantest, anterior drawer test and pivot shift test were negative in 76 patients. Compared to preoperative data, postoperative Lysholmscores, Tegnerscores and IKDC scores were significantly improved(P<0.05).  Conclusion Reserved stump had important significance in ACL reconstruction operation. ACL reconstruction operation with it could achieve a good clinical efficacy.
