I was suffering from patella tendinopathy. I am a contemporary dance and ballet student and this affected my education. I tried eccentric work for about 8 months and had no result at all. I had shock wave therapy for 3 sessions and it also wasn’t too effective. I then had a PRP injection. It was painful for about 3-4 days but gradually the pain and swelling decreased. I would recommend the treatment as my pain has decreased but I would advise people who would take PRP treatment that it would take a long time and to be patient.
