For those of you with chronic patellar tendinitis of the knees, which exercises have you found work best to prevent pain? I damaged my knees doing contact sports in my youth and I can no longer do certain leg movements (e.g., leg extensions) without experiencing a lot of pain & swelling. I also can’t train near failure on any leg movements or do below 12-15 reps or it will force me to take a 6 week lay off before training legs again. The meniscus in both of my knees looks great but my patellar tendons are very thick from having been partially torn so many times. I have advanced jumpers knee in both legs. I’ve read that having surgery to correct this problem is often not successful. Maybe someone on this forum can tell me otherwise. I’m sure I’m not the only one over the age of 50 fighting this battle. Any helpful advice would be appreciated. Thanks in advance!
