Objective:
To investigate and evaluate the results of arthroscopic posterior cruciate ligament (PCL) reconstruction with Achilles allograft using transfemoral double-bundle and tibial inlay technique.
Methods:
From September 2005 and August 2007,10 patients underwent arthroscopic PCL reconstruction with double-bundle Achilles allograft, which were deep-frozen and radiated by gamma ray. Two absorbable interference screw in the femur and tibial inlay technique were performed to fix the allograft. Clinical results were evaluated according to the physical examination, Lysholm and IKDC clinical rating scales.
Results:
The body temperature got to normal level 8 days after surgery. Immunologic rejection was detected but not serious and there were no infection found. All patients were followed up for 6 to 23 months (average 17 months). At the last follow-up, there was no positive Sag sign, Lachman test and PDT were all negative or grade I positive. The average Lysholm score of the 10 cases was 39(25-56) before operation, and 85 (79-92) at the last follow up, 41(28-62) before operation and 86(81-90) at the last follow up for IKDC. Statistical differences existed before and after operation in the two Lysholm and IKDC scores. By Lysholm score, 90% patients got an exellent or a good result; By IKDC score, all patients got an excellent or good result.
Conclusion:
This study has showed that PCL reconstruction with Achilles allograft using transfemoral double-bundle and tibial inlay technique is an effective method.
