THE CONDITION
The patella tendon is a structure that runs from below the kneecap (Patella) to the shin bone (tibia). Its function is to straighten the knee. Acute inflammation of the patella tendon is called patella tendonitis. If this persists the tendon degenerates leading to patella tendinosis.
Anyone can be affected by this condition but it is most common in athletes who are involved in jumping sports, hence it is also known as “Jumpers Knee”. It is commonly seen in runners. Some things that increase the forces through the patella increasing the risk of patella tendinosis are:
POOR FLEXIBILITY IN THE QUADRICEPS
POOR FLEXIBILITY IN THE HAMSTRINGS
RAISED KNEECAP (PATELLA ALTA)
THE DIAGNOSIS
Diagnosis is usually clear from the symptoms and examination. MRI and Ultrasound scans will show subtle changes however these are usually ordered to rule exclude alternative diagnoses rather than confirm tendonitis.
THE SYMPTOMS
Patients complain of pain along the tendon, which can feel sharp,particularly after running or jumping. After exercise the pain might persists as a dull ache and the tendon is often tender to touch.
THE TREATMENT
The good news is that non-surgical measures are often successful. It takes a minimum of six weeks for the knee to improve and a strict programme of rehabilitation is needed. However, reoccurrence is not uncommon.
Conservative treatment options include:
