Patellar Tendon Injuries Non-Surgical Treatment

Nonoperative treatment is the first step for patients who have:

• Patellar tendinopathy: Chronic pain at the bottom of the kneecap from overuse, regardless of how long symptoms have been present.
• A partial tear with an intact extensor mechanism: Patients who can still perform a straight leg raise and hold the knee fully extended may be managed in a brace with close follow-up. 

Nonoperative treatment is not appropriate for a complete patellar tendon rupture. A complete rupture does not heal on its own, and the knee cannot be straightened without the tendon. These injuries require surgical repair, ideally within the first few weeks after injury, before the tendon retracts and scars.

Patellar tendinopathy is a degenerative condition rather than an inflammatory one. The tendon’s structure has become disorganized because repetitive load has outpaced its ability to repair itself. Rest may temporarily reduce pain, but it does not restore the tendon’s strength or its capacity to handle load, so symptoms often return as soon as activity resumes.

A structured, progressive tendon loading program remodels the degenerative tissue in a way that rest cannot. This type of program is the cornerstone of treatment for patellar tendinopathy. Recovery is measured in months, and patience and consistency with the loading program are what produce durable results.

For patellar tendinopathy

• Progressive tendon loading: Treatment usually begins with sustained, holding contractions of the quadriceps, which can reduce pain. Exercises then progress to heavy, slow strengthening, followed by faster, spring-like exercises and, finally, jumping and landing drills that prepare the tendon for sport.
• Activity modification: Temporarily reducing jumping, sprinting, and deep squatting keeps symptoms at a manageable level while the tendon rebuilds. Some pain during exercise can be acceptable, and your therapist will help you monitor how the tendon responds from day to day.
• Correcting contributing factors: Strengthening the quadriceps and hip muscles, improving flexibility of the quadriceps and hamstrings, and addressing limited ankle mobility reduce the load placed on the patellar tendon. Landing mechanics are retrained to spread force more evenly across the leg.
• Patellar tendon strap: A strap worn just below the kneecap may reduce pain during activity for some patients.
• Injections:Rynecki Baker avoids corticosteroid injection directly into the patellar tendon, as it weakens the tissue and raises the risk of rupture. Orthobiologic options, such as platelet-rich plasma (PRP), may be discussed in select cases. Dr. Rynecki Baker will review whether an injection makes sense for you and the evidence behind each option.

For partial tears

• Bracing: A knee brace protects the healing tendon, with gradual increases in permitted bending over time.
• Physical therapy: Therapy focuses on restoring quadriceps activation, motion, and strength as the tendon heals.
• Close follow-up:Rynecki Baker monitors the extensor mechanism and the tendon’s healing to ensure the tear is not progressing.

Return to sport is guided by milestones rather than the calendar alone. Athletes should be able to perform single-leg strengthening, running, jumping, and sport-specific drills without significant pain, with strength that closely matches the other leg. Continuing a tendon loading program after returning to play helps prevent symptoms from recurring.

Dr. Rynecki Baker follows patients closely during nonoperative treatment. Surgery may be recommended if a patient:

• Has tendinopathy that persists despite a well-executed rehabilitation program carried out over at least six months
• Has a partial tear that progresses or fails to heal
• Loses the ability to straighten the knee or perform a straight leg raise, which suggests a complete rupture
• A sudden pop followed by an inability to straighten the knee should be evaluated promptly.
