[[file:Patellar_tendon_rupture.JPG|thumb|left]] '''Patellar tendon rupture''' is a medical condition characterized by the complete or partial tear of the [[patellar tendon]], which connects the [[patella]] (kneecap) to the [[tibia]] (shinbone). This injury is often associated with sudden, forceful movements or trauma and can significantly impair the function of the [[knee joint]].

==Anatomy==
The patellar tendon is a crucial component of the [[extensor mechanism of the knee]], which includes the [[quadriceps muscle]], [[quadriceps tendon]], patella, and patellar tendon. This mechanism is essential for activities such as walking, running, and jumping.

==Causes==
Patellar tendon ruptures can occur due to:
* Sudden, forceful contraction of the [[quadriceps muscle]]
* Direct trauma to the front of the knee
* Degenerative changes in the tendon, often related to chronic conditions such as [[tendinitis]] or [[patellar tendinopathy]]
* Systemic diseases like [[diabetes mellitus]] or [[rheumatoid arthritis]] that weaken the tendon

==Symptoms==
Common symptoms of a patellar tendon rupture include:
* Sudden, severe pain in the front of the knee
* Swelling and bruising
* Inability to straighten the knee or perform a straight-leg raise
* A palpable gap at the lower end of the patella
* Difficulty walking or bearing weight on the affected leg

==Diagnosis==
Diagnosis typically involves a combination of:
* Clinical examination
* Patient history
* Imaging studies such as [[X-ray]] and [[magnetic resonance imaging|MRI]]

==Treatment==
Treatment options depend on the severity of the rupture:
* **Non-surgical treatment**: Partial tears may be treated with immobilization using a knee brace or cast, followed by physical therapy.
* **Surgical treatment**: Complete ruptures usually require surgical repair to reattach the tendon to the patella. Post-surgery rehabilitation is crucial for restoring knee function.

==Rehabilitation==
Rehabilitation involves:
* Gradual weight-bearing exercises
* Range of motion exercises
* Strengthening exercises for the quadriceps and surrounding muscles
* Functional training to return to daily activities and sports

==Prognosis==
The prognosis for patellar tendon rupture varies. With appropriate treatment and rehabilitation, many individuals can return to their previous level of activity. However, some may experience long-term complications such as decreased strength, reduced range of motion, or chronic pain.

==Prevention==
Preventive measures include:
* Proper warm-up and stretching before physical activities
* Strengthening exercises for the quadriceps and hamstrings
* Avoiding sudden increases in activity intensity
* Addressing any underlying medical conditions that may weaken the tendon

* [[Knee injuries]]
* [[Tendinitis]]
* [[Quadriceps muscle]]
