User:Mr. Ibrahem/Patellar tendon rupture

Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. Often there is sudden onset of pain and walking is difficult. In a complete rupture the ability to extend that knee is decreased. A pop may be felt when it occurs.

Injury to the patellar tendon generally requires a significant force such as falling directly on the knee or jumping from a height. Risk factors include patellar tendinitis, kidney failure, diabetes, and steroid or fluoroquinolone use. There are two main types of ruptures: partial and complete. In most cases, the patellar tendon tears at the point where it attaches to the knee cap. Diagnosis is based on symptoms, examination, and medical imaging.

Small tears may be treated with rest and splinting, followed by physiotherapy. Larger tears typically require surgery within a couple of weeks. Outcomes are generally good. Rates in the general population are not clear; however, in certain high-risk groups it occurs about 1 in 10,000 per year. They occur most often in those under the age of 40.
