Objective To compare the recovery of proprioception between autograft and allograft for anterior cruciate l igament (ACL) reconstruction. Methods Between January 2008 and January 2010, 40 patients underwent ACL reconstruction with autologous tendon (autograft group, n=20) and allogeneic tendon (allograft group, n=20). No significant difference was found in gender, age, disease duration, and function scores between 2 groups (P gt; 0.05). All the patients underwent the ACL reconstruction with single-bundle technique. The knee range of motion (ROM), International Knee Documentation Committee (IKDC) score, and Lysholm score were measured after operation. The proprioception was assessedby the joint position sense (JPS) at 3 and 12 months postoperatively. The normal knee was used as control. Results Thepatients of 2 groups achieved heal ing of incision by first intention without compl ication of infection or haemarthrosis. Allpatients were followed up 12-18 months (mean, 13.5 months). There were significant differences in knee ROM, IKDC score, and Lysholm score between preoperation and 12 months postoperatively in 2 groups (P lt; 0.05). There was no significant difference in JPS 30°, JPS 60°, and JPS 90° between affected knees and normal knees in autograft group at 3 months postoperatively (P gt; 0.05). No significant difference was found in JPS 30° between affected knees and normal knees in allograft group at 3 months postoperatively (P gt; 0.05); but significant differences were found in JPS 60° and JPS 90° between affected knees and normal knees in allograft group at 3 months postoperatively (P lt; 0.05). There was no significant difference in JPS 30°, JPS 60°, and JPS 90° between affected knees and normal knees in 2 groups at 12 months postoperatively (P gt; 0.05). Significant differences were also found in JPS 60° and JPS 90° between affected knees of 2 groups (P lt; 0.05) at 3 months postoperatively, whereas no significant difference was found in JPS 30° between affected knees of 2 groups (P gt; 0.05). No significant difference was found in JPS 30°, JPS 60°, and JPS 90° between affected knees of 2 groups at 12 months postoperatively (P gt; 0.05). Conclusion Autologous andACL reconstruction is better than allogeneic ACL reconstruction in the recovery of proprioception at early time after surgery.
ObjectiveTo compare the effectiveness of coracoclavicular ligament reconstruction between by using autologous plantaris tendon graft combined with hook plate fixation and allogeneic tendon graft combined with hook plate fixation for treating acromiocavicular joint dislocation. MethodsThirty-three patients with acromioclavicular joint dislocation who accorded with the inclusion criteria between January 2013 and June 2014 were assigned into 2 groups. The patients were treated with autologous plantaris tendon graft combined with hook plate fixation in group A (n=17), and with allogeneic tendon graft combined with hook plate fixation in group B (n=16). Thirteen-one patients was followed up more than 12 months (15 in group A and 16 in group B). There was no significant difference in gender, age, cause of injury, sides, time between injury and surgery, and type of dislocation (P>0.05). The assessments included operation time, hospitalization time, hospitalization expenses, shoulder range of motion, gap of acromioclavicular, Constant-Murley scores, and visual analogue scale (VAS) for pain. ResultsThe operation time of group A was significantly longer than that of group B, and the hospitalization expense was significantly lower than that of group B (P<0.05). There was no significant difference in hospitalization time (t=1.046, P=0.316). The incisions healed by first intention, and hook plate was removed after 3 months. The mean follow-up time was 21.3 months (range, 19-34 months) in group A and was 23.7 months (range, 18-37 months) in group B. X-ray examination showed no osteolysis. There was no significant difference in gap of acromiocavicular between 2 groups at preoperation, 1 week after operation, and last follow-up (P>0.05). No redislocation of acromioclavicular joint and rejection reaction occurred during follow-up. At last follow-up, there was no significant difference in shoulder range of motion, Constant-Murley score, and VAS score between 2 groups (P>0.05). ConclusionCoracoclavicular ligament reconstruction by autologous plantaris tendon or allogeneic tendon graft combined with hook plate fixation for the treatment of acromioclavicular joint dislocation can achieve good effectiveness. The appropriate treatment should be chosen according to the patient's economic situation.
