Which graft type is noted for its potential quad atrophy delaying rehab after ACL repair?

The patellar tendon graft is associated with potential quadriceps atrophy that can delay rehabilitation after ACL repair because of its harvesting technique. When the patellar tendon is used for grafting, a portion of the tendon is removed along with a bone block from the patella (kneecap). This procedure involves cutting through the patellar tendon, which is directly connected to the quadriceps muscle. As a result, the disruption and subsequent healing of this tendon can lead to weakened muscle function and atrophy of the quadriceps, particularly in the early phases post-surgery.

In contrast, other graft types, such as hamstring tendon or quadriceps tendon grafts, typically have less direct impact on the quadriceps because they do not necessitate the same level of disruption or removal of the tendon that affects muscular function in the same way. Consequently, the rehabilitation process may be less impeded with these grafts, allowing for a quicker return to function.

Therefore, the choice of a patellar tendon graft may lead to notable quadriceps atrophy, which is a critical factor to consider in post-operative rehabilitation planning.
