Abstract:
ObjectiveTo evaluate and compare long-term clinical outcomes of arthroscopic anterior cruciate ligament (ACL) reconstruction with remnant preservation versus remnant resection.MethodsFrom October 1999 to May 2005,standard ACL reconstruction with autogenous quadrupled hamstring tendons under arthroscopy using remnant resection with transtibial techniques was conducted in 87 patients.From June 2005 to May 2010,ACL reconstruction with autogenous quadrupled hamstring tendons using outside-in bone tunnel establishment and remnant preservation was performed in 221 patients.Only the patients who underwent simple ACL reconstruction together with more than three years follow-up records were enrolled in the study,including 66 patients in remnant preservation group and 39in remnant resection group.ResultsPatients of both groups were all followed up for 36-60 months,which showed insignificant difference between groups ( P ＞ 0.05).Compared with the preoperative data,the latest follow up data demonstrated satisfactory outcomes in both groups.The two groups showed no significant differences regarding the preoperative data including age and gender distribution,average time from injury to surgery,joint instability extent and functional score of the affected knee ( P ＞ 0.05 ).There was no statistical difference in regards of the thigh muscle atrophy and Lachman test between groups ( P ＞0.05).However,the remnant preservation group was superior to the remnant resection group in aspects of the range of motion of the affected knee,Lysholm score,stability in anterior drawer test,stability in pivot shift test and international knee documentation committee (IKDC) grade ( all P ＜ 0.05 ). ConclusionCompared with standard ACL reconstruction using remnant resection with transtibial techniques,the ACL reconstruction using outside-in bone tunnel establishment and remnant preservation has better longterm clinical outcomes including stability and function of the affected knee.
