My pediatrician says my child may have knee cap tendon rupture, but I don't understand. What does it mean?

Tendon rupture. The patella, or knee cap, has two major tendons that attach it to the bones and muscles around it - the patellar tendon and quadricepts tendon. If they are injured, they can usually be treated with therapy and bracing. Complete tears sometimes required surgery.
Torn tendon. Tendon ruptures about the pediatric knee cap can occur. Kids sometimes pull off a piece of bone at the tendon attachment site. Cases in which this is minimally displaced do not require surgery, cases with more significant displacement can. Could also be referring to case of patellar dislocation which is typically initially managed nonoperatively. Sounds as though speciality referral is needed.

My doctor says I have knee cap tendon rupture, but I don't understand. What does it mean?

Tendon Injuries. Injuries to the tendons on either side of the knee cap or patella can be either chronic or acute. Chronic injuries are more likely to be tendinitis with small partial tears. Acute injuries can be associated with a complete tear or rupture of the tendon. The tendon above the patella attaching to the quadriceps muscle is the quad tendon. The tendon below the patella is the patellar tendon.
If complete, surgery. Dr. Bramhall's description is on the money. If the tendon is torn completely, it will not heal well without surgery. If it does not heal well, you will not be able to walk without significant problems. Except for patients who are extremely ill, all knee cap tendon ruptures require surgery.

Mom is caregiver for elders in the family. Now she has a problem. What does it mean to have knee cap tendon rupture?

Torn tendon. Sounds like patellar tendon or quad tendon rupture. Complete tearing of either generally requires surgical repair or the individual will be unable to actively extend their knee making walking very difficult. Can't really be rehabed alone as the quad muscles have lost their attachment to the tibia below the knee joint.
Marked restriction. Knee cap tendon rupture also known as rupture of the ligamemtum patellae means an inablity to completely straighten your knee; would require surgical repair and would have restrictiion in the range of movemeny of the knne and may even have trouble with walking if not properly treated and managed. Would check for underlying problems in the knee also.

I've got knee cap tendon rupture. Now what?

Orthopedic exam. It is very important to see an orthopedist asap if you ruptured either your patella tendon or the quad muscle attachment to the patella, you might require surgery to correct the problem and obtain the best result.
Likely surgery. If you have completely ruptured your patellar tendon or quad tendon, surgery is usually necessary to allow for successful healing and maintenance of your extensor mechanism. Ask your orthopaedic surgeon.

What's the outcome of knee cap tendon rupture?

Surgery. A rupture of either the quadriceps tendon (above kneecap) or of the patella tendon (below kneecap) are both treated surgical especially if it is a complete tear. These two tendons are critical for proper knee function. They are responsible for straightening the knee.
Surgery required. Complete rupture of the patellar tendon (tendon that connects the knee cap or patella to the tibia) results in loss of ability to extend the knee. This requires surgical intervention by an orthopedic specialist. Recovery can take as long as 6 to 12 months and most patients return to their baseline activities but may experience some residual stiffness.
Mostly good. Most knee cap tendon ruptures heal with return of good range of motion and strength. However, the healing process takes several months. Furthermore, there may be subtle deficits such as a little less bending, slightly less strength, and maybe a little less return of muscle bulk. But what is crystal clear is that the surgical outcomes are significantly better than non-operative care in most patient.
