There are four different tendons an orthopedic surgeon can choose from to restore knee stability during anterior cruciate ligament surgery. The four tendons are: quadriceps tendon, patella tendon, hamstring tendon and donor tendon. This blog is about the quadriceps tendon. We will discuss what a quadriceps tendon is and the advantages and disadvantages of this tendon.
Every year in the Netherlands, about nine thousand people undergo anterior cruciate ligament reconstruction. A tendon that will function as a cruciate ligament is used to make a new one. There are several options for this. The tendon used to make a cruciate ligament from is called a "graft" in medical jargon. Which tendon your anterior cruciate ligament will be made from is useful to know. In this blog, you'll read about the factors the orthopedic surgeon uses to choose your graft and the differences between grafts.

The ACL is a Dynamic structure, rich in neurovascular supply and comprised of distinct bundles, which function synergistically to facilitate normal knee kinematics in concert with bony morphology. Characterized by individual uniqueness, the ACL is inherently subject to both anatomic and morphological variations as well as physiologic aging.

Relative to the patellar tendon, the quadriceps tendon sits at the top of the kneecap. The difference with the kneecap tendon is that it has a bone block on one side. This, like the patellar tendon, has the advantage of growing into place faster. However, the quadriceps tendon can also be gained without a bone piece. The quadriceps is a strong and thick tendon and therefore suitable as a graft for anterior cruciate ligament reconstruction.
The patellar tendon technique usually produces pain at the front of the knee to a greater or lesser degree. The hamstring technique is an alternative in this regard. But the hamstring is also the muscle that inhibits the forward displacement of the lower leg and thus supports the function of the anterior cruciate ligament. Compared to the quadriceps, the hamstrings are naturally less powerful muscles. The idea behind using the quadriceps tendon is to prevent pain at the front of the knee (patellar tendon) and maintain hamstring function. Another advantage is that the quadriceps tendon is easy to gain. In addition, it is a strong and thick tendon.
The disadvantage of the quadriceps technique is that the quadriceps muscle is affected by the removal of part of the tendon. Recovery of control and strength requires more time because of this. Flexion also usually needs more time and attention to recover. Because of both factors, rehabilitation generally takes longer and recovery takes relatively longer. A cosmetic drawback may be reduced healing of the skin. Because of the pulling forces on the wound, the scar may not recover as nicely. In conclusion, the use of the quadriceps tendon is a fairly new technique. Because of this, few long-term effects are yet known.
