I had my tendons attached to knee totally ripped free from the patella taking some bone with it a little over a year ago. I did some research on the healing of tendons. It's hard to find much on it, but tendons are slow to heal because of very slow cell turnover for tendons. They typically renew themselves about once every 3 decades. They don't usually need a lot of nutrients, and blood flow to them is much less then say muscle cells.
Physically and naturally you can help this (with enough time) by having one of those flexible shower (the ones with the hose extensions) heads you can focus on any area. You change the water from very cold to as hot as you can take it, and apply it to the injured area (alternate between cold and hot a number of times), then do deep tissue massage in between for several minutes about 3 times a day. This should help hugely, even more than the test. This process speeds up the blood flow, oxygen and nutrients (including healing factors) that reach the area many times over. Be your own physical therapist, as you are with you far more of the week than any therapist can be.
Also, I'm personally giving Super Cissus Rx a try at 6 caps a day for first month and 3 caps per day after that. Cissus is said by many to be the best natural tendon, ligament, and joint healer out. It has detractors that say it doesn't work, but a lot of people say it's great. I've never tried it before and 6-8 weeks from now will be my first trial. I intend to use a moderate dose of the Andro Series by PP, the Super Cissus, my water massage techniques over an 8 week period of time to see if I can speed up my healing process to several times the normal s-l-o-w healing rate for these problems. I will also test the healing rate with constant light workouts for the area, and working on new range of motion. The ability to twist my knee is very impaired, and I'll work on that on top of pure strength to the area. I feel that any tendon repair test should be given at least 8 weeks to see what happens.
