Dr Henry has given you a thorough synopsis of the options in terms of injection treatments, but I thought that I would give some anecdotes from clinical practice.
Situations where my patients have tried PRP for knees include
1. OA
2. Chondromalacia Patella
3. Osteochondral defects
4. Patella tendinoapthy/tears
For some, it works well. For others - not so.
Personally, I think it’s worth trying as there should be minimal side effects and if done under ultrasound guidance, you can be sure that the PRP is placed correctly.
The main caveat is that it is not cheap - even in subsidised institutions. The equipment usually costs $200-300 on top of the procedure. Privately will be considerably more.
After the procedure, you will need to rest for a few days and rehab is a MUST!
Hope this helps.
