Patellar Tendon Treatment Options

Can a patellar tendon rupture be treated without surgery?

In some cases, a partial rupture of the patellar tendon may be treated non-surgically with rest, immobilization using a hinged knee brace locked straight, and physical therapy. A platelet rich plasma (PRP) injection directly to the affected tendon can also help relieve knee pain and promote healing of the partial thickness tearing of the tendon. Moreover, extracorporeal shock wave treatments have also been shown to produce good outcomes.

However, it is important to note that complete patellar tendon ruptures often require surgical repair to regain full knee function. Additionally, even in cases of a partial patellar tendon rupture, if you cannot perform a straight leg raise, surgical intervention will likely be recommended.

What are the surgical options for a patellar tendon rupture?

Surgical options for patellar tendon ruptures typically involve reattaching the torn patellar tendon to the patella using sutures or non-metal anchors. The choice of surgical technique depends on the extent of the injury and the characteristics of the tissue. Bone tunnels [33-3] and anchors [33-2] can be used and have demonstrated excellent long term outcomes.

In cases of more severe injury or chronic injury to the patellar tendon, Dr. Chahla may recommend reconstructing the tendon using either an Achilles tendon allograft (donor tissue) or a biologics patch known as Regeneten. Regeneten is a collagen-based implant that supports the body’s natural healing response to facilitate new tendon-like growth and mitigate strain at the site of the patellar tendon tear. Regeneten is composed of Type 1 collagen and has been observed for up to 5 years to increase and sustain the repaired patellar tendon thickness.

How long is the recovery after a patellar tendon repair/reconstruction?

Initially following the surgical repair of the patellar tendon, you will be allowed to bear full weight on the operative leg using crutches as tolerated by pain. You will be required to wear a hinged knee brace for 6 weeks following surgery. Initially, this brace will be locked straight. Physical therapy will begin immediately following surgery, and you will be allowed to gradually progress the range of motion of the operative knee over a period of 6 weeks per Dr. Chahla’s patellar tendon repair/reconstruction post operative protocol. Physical therapy is a crucial part of the recovery process to regain strength and mobility. Full recovery can take six months to a year.

What are the long-term effects of an untreated patellar tendon rupture?

An untreated patellar tendon rupture can lead to chronic knee pain, weakness, and a significant loss of knee function. It can also increase the risk of developing osteoarthritis in the affected knee over time. Therefore, prompt treatment is crucial to prevent long-term complications.
