Minimally invasive harvesting of the quadriceps tendon: Technical note

The quadriceps tendon is gaining preference as an autograft over conventional grafts for the primary reconstruction of the anterior and posterior cruciate ligaments and of the medial patello-femoral ligament. In the past, the use of the quadriceps tendon was associated with considerable morbidity and less favourable outcomes compared to other grafts, specifically due to post-operative weakness of the quadriceps and other complications such as patellar fracture and rupture of the extensor apparatus. These problems are partially ascribable to the graft harvesting method used (large incision, bone block>2cm, and full-thickness tendon harvesting). Recent technical advancements have made reproducible harvesting of quadriceps grafts possible, thereby largely preventing the complications. In this study we describe an original quadriceps tendon harvesting technique in which a minimally invasive approach allows the collection of a sufficiently long graft, while sparing the deep layer of the quadriceps tendon. This technique decreases intra-operative morbidity and improves the post-operative outcomes.
