The knee is a complex joint where the thighbone (femur), shinbone (tibia), and kneecap (patella) meet. Stability and movement are supported by multiple structures, including cartilage, ligaments, and tendons.

The quadriceps muscles at the front of the thigh are connected to the top of the kneecap (patella) by the quadriceps tendon. The bottom of the patella is connected to the shinbone (tibia) by the patellar tendon. Together, these structures form a continuous mechanism that allows the knee to straighten when the quadriceps contract.

Patellar tendonitis develops when the tendon becomes irritated or inflamed, usually due to repetitive stress. Microtears can form in the tendon tissue when the load exceeds the tendon’s ability to repair itself, leading to pain and dysfunction.

Common risk factors include:

• Overuse from repetitive jumping, sprinting, or heavy lifting
• Rapid increases in training intensity or frequency
• Poor flexibility or strength in the quadriceps and hamstrings
• Misalignment or instability in the knee joint
• Inadequate warm-up or recovery practices

Initially, patients may experience mild discomfort during activity. Over time, the pain can become more persistent and interfere with daily movements or athletic performance.

The hallmark symptom of patellar tendonitis is pain located just below the kneecap. This discomfort may be felt during or after activity and may worsen when squatting, jumping, or climbing stairs. The area may also feel tender to the touch and stiff after periods of rest.

In many cases, patellar tendonitis can be managed without surgery. Early intervention often leads to better outcomes. At Vitality Orthopedics and Biologics, we emphasize personalized, non-invasive treatment strategies that target the root cause and promote long-term healing.

Conservative options may include:

• Activity modification to reduce stress on the tendon
• Physical therapy focused on stretching tight muscles, strengthening weak muscle groups, and correcting movement patterns
• Bracing or taping techniques to unload the tendon and support alignment
• Anti-inflammatory medications as needed to reduce pain and swelling

When conservative care alone is not enough, regenerative medicine offers a promising pathway for enhanced recovery.

Regenerative medicine harnesses the body’s own healing potential to repair damaged tissue and reduce inflammation. These therapies are especially valuable for chronic or stubborn cases of patellar tendonitis.

Red light therapy

Also known as low-level light therapy (LLLT), red light therapy uses specific wavelengths of light to penetrate deep into tissues. This stimulates mitochondrial activity, enhances circulation, and promotes tissue regeneration. Patients often experience a reduction in pain and stiffness with consistent treatments.

Laser therapy

Therapeutic laser devices deliver concentrated light energy to the affected area. This promotes cellular repair, reduces inflammation, and increases blood flow to the tendon. Laser therapy is often used in combination with other treatments to accelerate recovery.

Hyperbaric oxygen therapy (HBOT)

HBOT involves breathing 100% oxygen in a pressurized environment. This increases oxygen delivery to injured tissues, which can enhance cellular repair and reduce chronic inflammation. For tendon injuries, HBOT can support faster healing and improved tissue quality over time.

Platelet-rich plasma (PRP)

PRP therapy involves drawing a small amount of the patient’s blood, processing it to concentrate the platelets, and injecting it directly into the injured tendon. Platelets are rich in growth factors that stimulate tissue repair. PRP has shown positive outcomes in reducing pain and improving tendon strength in chronic tendonitis cases.

Bone marrow aspirate concentrate (BMAC)

BMAC is a regenerative therapy derived from a patient’s own bone marrow. It contains a mix of stem cells and growth factors that promote the regeneration of damaged tissues. When injected into the patellar tendon, BMAC can support healing and potentially restore tendon function more effectively than standard treatments.

BPC-157 peptide therapy

BPC-157 is a synthetic peptide with powerful healing properties. It promotes angiogenesis (formation of new blood vessels), collagen production, and tendon repair. This therapy may be administered orally or via injection and is often used as part of a broader regenerative protocol to enhance tissue recovery.
