摘要

AIM To present the long-term results of complex knee injuries,treated early using the Ligament Augmentation and Reconstruction System(LARS)artificial ligament to reconstruct posterior cruciate ligament(PCL).METHODS From September 1997 to June 2010,thirty-eight complex knee injuries were treated,where early arthroscopic PCL reconstructions were undergone,using the LARS(Surgical Implants and Devices,Arc-sur-Tille,France)artificial ligament.Exclusion criteria were:Late(>4 wk)reconstruction,open technique,isolated PCL reconstruction,knee degenerative disease,combined fracture or vascular injury and use of allograft or autograft for PCL reconstruction.Clinical and functional outcomes were assessed with IKDC Subjective Knee Form,KOS-ADLS questionnaire,Lysholm scale and SF-12 Health Survey.Posterior displacement(PD)was measured with the Telos Stress Device.RESULTS Seven patients were excluded;two because of coexisting knee osteoarthritis and the remaining five because of failure to attend the final follow-up.The sample consisted of 31 patients with mean age at the time of reconstruction 33.2±12.5 years(range 17-61).The postoperative follow-up was on average 9.27±4.27 years(range 5-18).The mean average IKDC and KOS scores were 79.32±17.1 and 88.1±12.47%respectively.Average PD was 3.61±2.15 mm compared to 0.91±1.17 mm in the uninjured knees(one with grade 1+and two with grade 2+).Dial test was found positive in one patient,whereas the quadriceps active drawer test was positive in three patients.None was tested positive on the reverse-pivot shift test.The range of motion(ROM)was normal in thirty knees,in comparison with the contralateral one.There was no extension deficit.Osteoarthritic changes were found in three knees(9.6%).CONCLUSION Early treatment of complex knee injuries,using LARS artificial ligament for PCL reconstruction sufficiently reduces posterior tibia displacement and provides satisfactory long-term functional outcomes.
