Arthroscopic posterior cruciate ligament reconsruction by double-tunnel of femur and inlaying of tibia / 中国矫形外科杂志

ABSTRACT

[Objective]To describe a new way of arthroscopic posterior cruciate ligament reconstruction and evaluate the early stage of follow up results.[Method]Twenty four consecutive cases of isolated and combined posterior cruciate ligament deficiency were studied.Quadriceps tendon patellar bone was used for preparation of "Y" shaped autograft.Double-tunnel of femur were drilled and tibia was inlayed at their anatomical footprint.[Result]All cases were followed up for 24 months to 30months,averaging 24.5 months.Lysholm rating scales were used to make clinical subjective evaluations.Lysholm scores raised from 49.20?1.44 before operation to 87.91?1.52 after operation.Finial Lysholm evaluation showed 7 patients were excellent,16 good,and 1 poor.The good to excellent rate was 95.8%.Anteroposterior translation as clinical objective evaluations was measured with KT-1000.KT1000 arthrometer measurement showed that the average posterior translation improved from 12.85?1.10mm preoperatively to 3.98?1.99mm postoperatively.One patient was graded as failure.[Conclusion]Arthrosopy assisted prodedure of double bundle posterior cruciate ligament reconsruction using quadriceps tendon patellar bone autograft by double-tunnel of femur and inlaying of tibia is effective and reproducible.The short follow up clinical results are encouraging.
