Nonsurgical Treatment
Very small, partial tears respond well to nonsurgical treatment.
Immobilization. Your doctor may recommend you wear a knee immobilizer or brace. This will keep your knee straight to help it heal. You will most likely need crutches to help you avoid putting all of your weight on your leg. You can expect to be in a knee immobilizer or brace for 3 to 6 weeks.
Physical therapy. Once the initial pain and swelling has settled down, physical therapy can begin. Specific exercises can restore strength and range of motion.
While you are wearing the brace, your doctor may recommend exercises to strengthen your quadriceps muscles. Straight-leg raises are often prescribed. As time goes on, your doctor or therapist will unlock your brace. This will allow you to move more freely with a greater range of motion. You will be prescribed more strengthening exercises as you heal.
This is what has me confused about this
Surgical Treatment
Most people require surgery to regain knee function. Surgical repair reattaches the torn tendon to the kneecap.
People who require surgery do better if the repair is performed soon after the injury. Early repair may prevent the tendon from scarring and tightening into a shortened position.
Hospital stay. Although tendon repairs are sometimes done on an outpatient basis, most people do stay in the hospital at least one night after this operation. Whether or not you will need to stay overnight will depend on your medical needs.
The surgery may be performed with regional (spinal) anesthetic which numbs your lower body, or with a general anesthetic that will put you to sleep.
Procedure. To reattach the tendon, sutures are placed in the tendon and then threaded through drill holes in the kneecap. The sutures are tied at the top of the kneecap. Your surgeon will carefully tie the sutures to get the correct tension in the tendon. This will also make sure the position of the kneecap closely matches that of your uninjured kneecap.
I need to know more about the pros and cons, but I cant see an NBA player not electing for surgery
