Meta-Analysis - Hamstring versus Patellar-Tendon Graft
This study compared 32 autograft patellar studies to 32 autograft hamstring studies. All the studies were English language reports that had at least a 2 year follow-up and included stratified KT-1000 results with 30 lb or maximum manual arthrometric testing force. The results showed that four-strand hamstring grafts had overall higher stability rates than patellar grafts. Additionally, the results indicated that four-strand hamstring stability rates were fixation dependent. The highest stability rates were found in hamstring grafts using EndoButton femoral fixation and second-generation tibial fixation.
Meta-Analysis - Autografts versus Allografts
This study compared 20 allograft studies to the 64 studies used in the paper listed above. The same selection criteria was used to select the studies. Normal stability was 72% for all autografts and 59% for allografts. Abnormal stability, which usually indicates graft failure was 5% for autografts and 14% for allografts. Hamstring results were better than patellar results for both groups.
