First off, I'm very happy I found this forum. It seems you guys are pretty ***n helpful.
Onto my problem. I'm (just gone lately) 17 years old, pretty fit and always playing basketball. In the school holidays I would play on outdoor courts for about 8 hours a day, everyday. I wanted to increase my jumping ability, so I did a thing caled Air Alert, its basically a exercise progran where you do these different leg exercises and jumps that make your legs more explosive. I had to pull out in week 8 becaue my shins started hurting very badly. I still played on my sore shins and they started to get quite bad. I took a 3 week rest and then started playing light ball again, and the shin pain wasn't too bad. Then I did Air Alert again, and pulled out at week 5 with not just shin pain, but a very painful tenderness in my left knee.
After about 5 weeks of light ball, I tried again, only to pull out in week 2 because of the knee pain. I continued to play basketball off an on for about 4 months and the knee gradually got worse, I lost all my jumping ability (my left knee = jumping leg) and my explosiveness, plus I couldn't play defence because it was very uncomfortable putting weight on my knee went it was bent. I decided a couple weeks later to go to a doctor and get it checked out, and he sent me in for X Rays, which showed nothing.
I played basketball off and on, stopping each time my knee started throbbing again for months. Now I am at the point where I have been off basketball for about a week, but the last 3 months have been ***l. I can't bend over to pick stuff up without pretty bad pain. Walking down/up stairs hurts like ***l. I can't run for more than 3-4 minutes without my knee aching. Then comes school, which for PE we have to do a running program that requires us to train for a half marathon. We have to run anywhere from 25-50kms a week. During our first few classes we went on 5km runs to guage where we were at, and I ran fine. I put all the weight on my right leg and kept my left knee almost straight the whole time and had no problems. I continued like that for a few weeks. Now my right knee has developed the same problem as my left, only worse. I don't know exactly what it is, and because I am sorta a "quiet complainer" my Mum doesn't think I am in that much pain - but I am.
I used to be so active and now I can't do anything, and I will fail PE this year because of this injury. I have read about knee injuries and Patellar Tendonitis seems to be the closest thing, but I am yet to be officially diagnosed. As I said, Mum doesn't think much of it so she never gets round to setting an appointment. I want scan that can show more than just bone and a physio, but my doctor is a bit of a ****er when it comes to going further than saying "sore knee".
Sorry for the extremely long post but I really want to know if you guys think it is patellar tendonitis? (my symptoms: throbbing/tenderness right under knee and sometimes around knee, weakness in knee, pain when bending w/ weight , throbbing when involved in jumping activities ie. basketball)
And if anyone else here has ever had it, how long did it take to recover and after recovery was the knee 100% or is it a lingering pain?
