Hamstring tendon autograft better than bone patellartendon bone autograft in ACL reconstruction A cumulative meta-analysis and clinically relevant sensitivity analysis applied to a previously published analysis

BACKGROUND: Current debate on treatment options for anterior cruciate ligament (ACL) reconstruction complicate the choice between hamstring and bone-patellar tendon-bone autografts. We hypothesized a priori that cumulative meta-analysis (a form of sensitivity analysis) might show that the evidence for reduction of morbidity by hamstring grafts could have been reached at an earlier time. Furthermore, we hypothesized a priori that modern …
