Good move going with the PRP injection, I hear nothing but good results when combining PRP with the surgery. I have two views on meniscus surgery: 1 as a patient who underwent arthroscopic meniscus repair and 2 as a physical therapist assistant who has been working in the field for a short while now.
1) I underwent meniscus repair surgery where they sutured down a bucket handle tear along my lateral meniscus almost 2 years ago now when I was 24 while sparring during brazilian jiu jitsu. At the time, I was very clueless when it came to meniscus surgery options. Promises of "it'll be better for your knee long term" and "you'll regain full function and ROM" with the repair pushed me to agree with the doctor and move forward with the repair. The rehab took a very long time as my knee took much longer than normal to heal even with all of the rehab work both at home and with the PT (just about 8 months). I fell into a depression because all of my outlets were physical activities (BJJ, tennis, lifting, etc.), I gained 15 pounds, and wasn't at all happy with the results at the time. Physical therapy was rigorous but the recovery is truly about the work you put in at home. You're with the PT for an hour MAYBE an hour and a half, the HEP(home exercise program) needs to be followed and then some. Now at 20 months out I can almost touch my heel to my ass when sitting back onto my heels (which I was easily able to do before with both legs and now only one), my strength is back, my ROM is just about full range. Some mornings I feel soreness in the repaired knee from the cold, my mind has set up a block when it comes to certain movements and thus i'm still retraining some movements. I'm playing tennis at full ability again but I'm too afraid to go back to BJJ even though I love it so much. There's constant work that goes on loooooooong after you're done with PT. Had I gotten the meniscectomy i'd have been up and walking and even playing tennis and training just weeks later albeit without a meniscus which would lead to arthritis. Do I regret having the repair done? Yes. The repair isn't forever. Chances are, it'll tear again especially with my level of activity. But for now it "saves" my knee from arthritis. Good trade
2) As a PTA i've seen many cases of mensicus repair/meniscectomy/shaving down/PRP/Stem cell/voodoo. I can say with the utmost confidence that people that get the mensicectomy or shave the thing down are considerably happier with the results. The patients that i've seen get the repair struggle and boy is it a struggle. Some people will heal and be up and about at max ability in 4 months and some will take much longer. It's dependent person to person and also upon how much PT work they do. My PT from the hospital sucked and thats another thing, you need to find a good PT that will push you and work with you and your abilities. What the doctors wont tell you with the repair is that you basically forget how to walk and will have to have your gait retrained alongside building up the supporting musculature in your leg and hips. There is a lot to fix when coming off of a meniscus repair. The PRP/Stem cell stuff has worked in the cases that I have seen. The meniscus has very poor blood flow so when you directly inject platelet rich plasma into it you're basically feeding it the blood materials that it lacks thus aiding the healing process. At least that's how I understand it.
I think I covered a lot of it. Sorry y'all my mind is all over, i have the flu and am typing this in bed with a fever
