| Objective : To introduce arthroscopic posterior cruciate ligament(ACL) reconstruction surgical approach with the tendon Through the middle gap of remnant fiber。Evaluate the recovery of postoperative knee function and the Preliminary proprioception.Methods: 17 cases of eligible patients of posterior cruciate ligament ruptures were carried arthroscopic Single-beam type anatomical reconstructed with the tendon through the middle gap of remnant fiber from August 2012 to March 2014. the tendon is fixed in operation through suspension of end-button and Extrusion of bioabsorbable interference screw.The recovery of Knee function is assessed with Comparative Analysising the preoperative and postoperative Lysholm and IKDC subjective scores and KT-1000 scores,and the postoperative proprioception of knee is assessed through measuring the TTDPM and PRP scores.Results : there was no serious complications for all patients during the postoperative 12 month follow-up. Subjective scores showed: Lysholm scores from an average of(54.4 ± 8.0) scores increased to(90.1 ± 2.7) scores for 12 months followed up(P <0.05); IKDC knee scores from preoperative average(60.3 ± 3.5) scores increased to(87 ± 1.5) scores after follow-up(P <0.05), All patients reached the pre-injury level of daily life.The results appear as objective scores: preoperative KT-1000 measured mean scores(8.7 ± 2.1) mm, followed up 12 months measured the mean scores(1.8 ± 0.7) mm,proprioception tests follow up 12 months showed, the knee PRP mean Angles respectively in 15 °, 45 °, 75 ° and the mean TTDPM Angles test at 45 ° Compared with the contralateral showed no significant difference(P> 0.05).Conclusion:Arthroscopic posterior cruciate ligament reconstruction with tendon throughing remnant fiber Can effectively restore the stability of the knee and improve knee function,preserving remnant stubs and synovial of PCL may be beneficial recovery of proprioception and healing of reconstruction tendon. |
