Tendonosis, also known as tendinosis, is a chronic condition characterized by degeneration, thickening, and disorganization of a tendon without significant inflammation. Unlike tendonitis, which involves inflammation, tendonosis results from repetitive microtrauma, aging, or overuse. It commonly affects tendons in areas like the shoulder, elbow, or knee. Symptoms include pain, stiffness, and reduced function. Treatment often involves rest, physical therapy, and targeted exercises to promote tendon healing and strengthen surrounding tissues. In some cases, more advanced interventions such as shockwave therapy (available in our clinic) or surgical procedures may be considered.
1. What are Knee Tendon Conditions?
Knee tendon injuries range from tendinitis (inflammation of a tendon) to a ruptured (torn) tendon. If a person overuses a tendon during certain activities such as dancing, cycling, or running, the tendon stretches and becomes inflamed. Tendinitis of the patellar tendon is sometimes called “jumper’s knee” because in sports that require jumping, such as basketball, the muscle contraction and force of hitting the ground after a jump strain the tendon. After repeated stress, the tendon may become inflamed or tear.
2. What are the Knee Tendon Injury Symptoms?
People with tendinitis often have tenderness at the point where the patellar tendon meets the bone. In addition, they may feel pain during running, hurried walking, or jumping. A complete rupture of the quadriceps or patellar tendon is not only painful, but also makes it difficult for a person to bend, extend, or lift the leg against gravity.
3. How do I Diagnosis a Knee Tendon Injury or Condition?
If there is not much swelling, the chiropractor or practitioner will be able to feel a defect in the tendon near the tear during a physical examination. An x ray will show that the patella is lower than normal in a quadriceps tendon tear and higher than normal in a patellar tendon tear. The practitioner may use an MRI to confirm a partial or total tear.
4. What Conservation Treatments exist for Knee Tendon Issues?
Initially, the treatment for tendinitis involves rest, elevating the knee, applying ice, and taking NSAID medications such as aspirin or ibuprofen to relieve pain and decrease inflammation and swelling. A series of rehabilitation exercises is also useful. Dr. Luciano Di Loreto
, our chiropractor, uses a combination of electrotherapy
, therapeutic ultrasound
, laser therapy
and soft tissue therapy
to treatment tendon injuries. If the quadriceps or patellar tendon is completely ruptured, a surgeon will reattach the ends. After surgery, a cast is worn for 3 to 6 weeks and crutches are used. For a partial tear, the doctor might apply a cast without performing surgery.
Rehabilitating a partial or complete tear of a tendon requires an exercise program that is similar to but less vigorous than that prescribed for ligament injuries. The goals of exercise are to restore the ability to bend and straighten the knee and to strengthen the leg to prevent repeat injury. A rehabilitation program may last 6 months, although people can resume many activities before then.
