Selecting the most effective ACL reconstruction autografts remains a critical decision for orthopedic surgeons worldwide. Historically, bone-patellar tendon-bone (BPTB) and hamstring tendon (HT) grafts were the primary choices for most cases. However, the quadriceps tendon (QT) has recently emerged as a robust and reliable alternative. A new meta-analysis of eleven randomized controlled trials evaluated these three options to clarify their clinical performance. Specifically, the study focused on patient-reported outcomes, joint stability, and overall complication rates in primary reconstructions.
The results showed no statistically significant differences in functional outcomes among the three groups. Specifically, pooled International Knee Documentation Committee (IKDC) scores averaged 84.8, while Lysholm scores reached 93.1. Furthermore, instrumented laxity tests revealed that side-to-side anterior tibial translation was consistent across all grafts, averaging 1.2 mm. These findings suggest that modern surgical techniques effectively achieve knee stability regardless of the autograft selected. Additionally, the analysis indicated that graft failure and reoperation rates were remarkably low across all included trials.
Regarding safety, the pooled graft failure rate across the study was only 0.7%. Moreover, reoperation rates remained around 2.3% without significant between-group differences. Interestingly, donor-site morbidity was comparable between the quadriceps and hamstring groups. However, the researchers noted that reporting for the BPTB group was often incomplete, which complicates direct comparisons for donor-site pain. Therefore, while QT appears to be a safe and effective option, surgeons should continue to consider individual patient profiles during the selection process. Consequently, these findings support the use of all three graft types as viable primary options.
No, high-level evidence suggests that quadriceps, hamstring, and bone-patellar tendon-bone autografts provide similar results regarding knee stability, patient-reported outcomes, and graft survival rates.
Studies show that quadriceps and hamstring tendons have similar donor-site morbidity profiles. However, some evidence suggests the quadriceps tendon may cause less donor-site pain compared to the patellar tendon grafts due to the lack of a bone block.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
