Hi. Sorry to hear about your injury–I feel your pain, literally. I’ve been struggling with knee/ankle problems related to a ski accident for more than one year, and my I still have serious anterior knee pain, and ankle pain, that prevent me from doing any cycling, running, real climbing, and so on.
Most recently, I saw a new doctor, which brought some new perspective, and a new planned date for surgery. Ligament reconstruction on ankle, exploratory arthroscopy, fat pad resection, and meniscus repair on knee.
The MRI shows that the most likely cause of my anterior knee pain is 1) Instability from my ankle injury, 2) fat pad impingement with patella and subsequent irritation, and 2) small tear of posterior horn of medial meniscus which has caused some swelling. After being told that I chronic patellar tendinopathy for one year, looking at the MRI with a perfect patellar tendon was interesting, to say the least. At least now I can look elsewhere for the cause of the ongoing pain.
One thing my doctor advised is that anterior knee pain can and often is caused by pain in other/deeper parts of the knee. He also would not make any more specific diagnosis than “anterior knee pain” without a set of good scans.
So, in your case, if you have not already done so, do your best to get an MRI, and maybe try to think beyond just the interaction of patella/femur.
If they find a clear and operable problem, I would say with your level of activity and drive, just go ahead and do it! Better that then go through the next year(s) of waiting, wondering, and frustration.
