Some FYI....
Cause of a Torn Patellar Tendon:
It has been found that in nearly all patients who sustain a patellar tendon rupture there is abnormal tendon tissue consistent with a chronic tendinosis. The patellar tendon is usually injured in the watershed region of the tendon, where blood flow to the tissue is poor, and the tendon is weakest.
Tendon tears can also occur in non-athletic settings. Usually there is a reason for the patellar tendon to be weakened in these individuals, such as a systemic disease that weakens tendons or recent surgery on the knee the caused tendon weakening. Treatment is usually similar in athletes and non-athletes alike.
Making the Diagnosis:
Making the diagnosis of a torn patellar tendon is usually obvious on clinical examination. People who tear the tendon will be unable to extend their knee against gravity, and unable to perform a straight leg raise test. The examiner can usually feel the gap in the tendon, just below the kneecap.
An x-ray will be obtained, as a patellar fracture can cause similar symptoms, and should be excluded as a possible diagnosis. On the x-ray, the patella is usually up higher when compared to the opposite knee, as the quadriceps pulls up on the kneecap, and nothing is holding it down. While often not needed, an MRI may be used to confirm the diagnosis and inspect the knee for any other damage that may have occurred.
Treatment of a Patellar Tendon Tear:
A torn patellar tendon does not heal well on its own, and left untreated will lead to weakness of the quadriceps muscle and difficulty with routine activities, including walking. Surgery to repair the torn tendon is relatively straightforward in concept, but can be difficult to perform.
The torn ends of the tendon need to be sewn together. The difficulty lies in the fact that it is important to restore proper tension to the tendon, not making it too tight or too loose. Also, it can be difficult to get a good repair, especially if the tendon has torn directly off the bone. In these situations, the sutures used to repair the tendon may have to be attached through the bone.
Recovery & Prognosis:
Recovering from a torn patellar tendon is difficult and takes time. One of the most important prognostic factors for recovery is the time to surgery, and surgery delayed beyond a few weeks can limit recovery ability. It is known that early mobility after surgery, protected strengthening, and preventing excessive stress on the repair will speed overall recovery. Even with these steps, there is a minimum of 3 months until return of normal daily activities, and 4-6 months until sports should be resumed.
While most people heal completely from a patellar tendon surgery, there can be long-term weakness even with a successful repair.
But, I digress.) Anyway, I feel for Graham and any other player that gets injured and can't be out there with their team.
