The quadriceps tendon is a thick, strong tendon that can withstand tremendous force.
In daily life, it acts as part of the extensor mechanism to straighten the knee.
All of these injuries have similar treatments and rehabilitation plans.

Atendonis a structure that attaches a muscle to bone.
The force of muscle contraction is transmitted through the tendon to move the bone.
It’s the extensor mechanism that allows us to straighten our knee or perform a kicking motion.
Causes
Partial quad tendon injuries can occur in association with athletic activities or active lifestyles.
These symptoms may cause gradually increasing pain over the kneecap and may be misdiagnosed as akneecap problem.
Complete quadriceps tendon tears are unusual injuries.
When this occurs, the sudden, opposing forces can exceed the strength of the quadriceps tendon.
An eccentric contraction can occur with injuries such as a slip on wet ground or a sports injury.
Complete tears of the quadriceps tendon require surgical intervention to regain strength in the extremity.
Surgery is performed to suture the torn tendon back to its attachment on the patella (kneecap).
Manysurgeonsallow earlyrange of motionexercises, but this should be done under the supervision of aphysical therapistor healthcare provider.
The brace can usually be discontinued after three months, and sports resumed in four to six months.
A Word From Verywell
A quadriceps tendon rupture is an uncommon injury that typically requires surgical treatment.
Without an intact quadriceps tendon, straightening the knee and walking normally can be difficult.
During surgery, the tendon is reattached to the top of the kneecap bone.
Rehabilitation is lengthy following quadriceps tendon repair surgery, but most people recover normal activities.
