RESUMEN
Objective To discuss the clinical effect of using autologous quadriceps tendon fixed by a patellar block as the graft to reconstruct posterior cruciate ligament (PCL ) under arthroscopy on a single-bundle way .Methods We treated 21 patients with damaged PCL using autologous quadriceps tendon fixed by a patellar block as the graft and absorbable interference screw fixation to reconstruct PCL under arthroscopy on a single-bundle way .Their functional recovery was evaluated by Lysholm scoring ,Tegner scoring and International Knee Documentation Committee (IKDC) criteria .Results All 21 patients got successful surgery on PCL reconstruction and multiple trauma ,no patients lost to follow-up .The subjective symptoms were improved after operation ,the post-operative Lysholm score and Tegner score were both significantly enhanced and showed statistical significance compared with the preoperative scores(P<0 .01) .Conclusion Using autologous quadriceps tendon fixed by a patellar block as the graft to reconstruct PCL on a single-bundle way leads to satisfactory short term clinical effects ,however ,the long term clinical effects remain to be eval-uated .
RESUMEN
Objective:To explore the result of segmental undercutting decompression in the Treatment of Lumbar Spinal Stenosis.Methods:A retrospective analysis of 213 cases of ineffective conservative treatment of degenerative lumbar spinal stenosis,who underwent the multi-segmental undercutting decompression surgery.Results:The patients post-operation following up ranged from 5 months to 6 years,the average follow-up were 3 years and 6 months,The outcome was excellent in 142 cases(66.7%),good in 59 cases(27.7%),fair in 11 cases(5.2%),poor in 2 cases(0.9%).94.4 percent have the excellent or good results.Conclusion:With control of surgical indications strictly,segmental undercuttingdecompression in the Treatment of Lumbar Spinal Stenosis is effective, and it can also preserve the stability and integrity of posterior structure of spine.
