The quadriceps tendon is a thick tendon that connects the quadriceps muscle to the kneecap and plays an important role in extending the knee joint.
A rupture (tear) of the quadriceps tendon can occur due to sudden overloading of the muscle, a fall, or direct injury. Symptoms include pain, swelling, and a palpable defect in the area of the tendon.
Diagnosis
The diagnosis is made through a clinical examination, imaging such as ultrasound or MRI, and functional testing.
Tendinosis of the quadriceps tendon develops due to overloading of the tendon over time and can be caused by repeated bending and straightening of the knee, especially during physical activity. Symptoms include pain, stiffness, and weakness in the area of the tendon. Diagnosis is also made through clinical examination and imaging.
Treatment
The treatment of a quadriceps tendon rupture can be conservative by immobilizing the leg with a brace or surgically by suturing the torn tendon. Rehabilitation involves physiotherapy to restore mobility and strength to the affected leg.
Tendinosis of the quadriceps tendon can be treated conservatively by reducing tendon stress, taking pain medications and anti-inflammatory drugs, and performing physical therapies such as ultrasound, electrical stimulation, and stretching exercises. In severe cases, surgery may be necessary to repair or remove the tendon.
Injections of hyaluronic acid or PRP (platelet-rich plasma) can also be used as supportive therapy in both cases to promote healing and regeneration.
