An evaluation of knee stability and functions following ACL reconstruction (semitendinosus/gracillis grafts) comparing manually versus mechanically tensioned grafts (using a tensioning device).

This study is looking at whether using a special device to apply a set tension to the new ligament during ACL (anterior cruciate ligament) reconstruction surgery leads to better knee stability and function compared to the surgeon doing it by hand. The ACL is the ligament inside your knee that stops it from buckling. When it tears — often from sport or a fall — surgery is needed to replace it with a tendon graft. Getting the right tension on the graft is important for a stable and well-functioning knee. This study compares the two tensioning methods to see which gives better results. You may be eligible if: - You are an adult between 18 and 40 years old - You have a confirmed torn ACL and are having primary (first-time) ACL reconstruction surgery - You are otherwise healthy and able to complete the required rehabilitation program - You can understand and follow instructions - You are willing to give written informed consent You may NOT be eligible if: - You have a serious medical condition (such as cancer or severe lung disease) that would prevent rehabilitation - You are unable to walk on two legs (with or without a walking aid) - You cannot put full weight on your leg after the operation - You have had previous major knee surgery on the same knee - You are not suitable for a hamstring tendon graft - You have also injured your knee cartilage, other ligaments, or other parts of the leg Talk to your doctor about whether this trial might be right for you.
