Knee Tendon Injuries

Anatomy, Pathology, and Treatments:

The quadriceps tendon is the continuation of the quadriceps muscles in the anterior compartment of the thigh where they originate from attachments to the femur (thigh bone) and pelvis. This tendon attaches to the top of the patella (knee cap). The lower end of the patella is attached to the upper end of the tibia (shin bone) by the patellar tendon. This is what is considered to be the extensor mechanism of the leg and is what is responsible for allowing you to straighten your knee.

Tramatic Tears
Traumatic tears of the tendons are associated with a violent contraction of the muscle as the tendon is being lengthened. This can happen when one falls down. People will usually lose the ability to actively straighten their knee. There are 2 distinct disease states that usually affect these tendons. The first is tendinitis, which is an active inflammatory process. This means that your body’s defense systems are responding to an injury that has been sustained to the tendon. This will typically respond favorably to anti-inflammatory type medications and potentially physical therapy.

Tendinosis is a separate process where the tendon undergoes degenerative type changes as a result of repetitive micro-trauma. The blood supply to the affected area of the tendon is disrupted and repair mechanisms for a tendon are impaired which results in a disorganization of the tendon. This lack of structural integrity may increase person’s chances of sustaining traumatic rupture of the tendon. Quadriceps or patellar tendon ruptures generally require surgical repair.

  • Pain
  • Pain with athletic activities (running & jumping)
  • Hearing a “pop” in the knee
  • Inability to straighten the knee

Pain is the most common symptom with tendinitis or tendinosis. This can happen during athletic activities such as running and jumping or with activities of daily living such as walking, stairs or bending. A tendon rupture is usually a very painful injury that is associated with hearing a “pop” in the knee. A person who sustains a rupture of one of these ligaments will not be able to fully straighten their knee.

I can not understate how much I would recommend Dr.Jimenez. I have been to a lot of doctors for my knees. Dr. Jimenez is the best. I had Bi-lateral knee replacement on Dec 30,2019. I was up and walking on day 2. Two weeks out walking with little assistance other than a cane. Most importantly, PAIN FREE! I honestly didnt think that would ever be possible again. I would recommend him to anyone. His staff is top notch. Very friendly and professional. They made me feel comfortable and kept me informed on what to expect throughout the process. Thankyou so much Naomi,Henry and Dr.jimenez! Yall are a Godsend!read more

Dr. Jimenez is an exceptional surgeon and an incredible person. He and his team go above and beyond for his patients. Dr. Jimenez replaced both my hips August 2018. Recovery was quick thanks to the surgical approach and Dr. Jimenez’s expert skill.  He is a real-life super hero!read more

I chose Dr. Jimenez based on the reviews. I had my first appointment with theNurse Practitioner. He was very pleasant and explained everything to me. I am still waiting for an appointment to get injections in both knees. The issue is with the Medical Assistant,Naomi. I talked with her personally and was told she hasn’t had time to get approval. I am inclined to go to a different Doctor just because of her attitude. She literally said she is only one person and injections weren’t a priority. I hope the Dr. And Nurse Practioner are aware that she is running patients more
