I know this is difficult to diagnose - it’s troublesome in person also. I have intermittent sharp pain in the front outer side of my left knee that feels like someone took a hammer to the funny bone. Happens when I’m walking, particularly when taking a left bend, but sometimes I can run and play tennis with no issues.

It’s usually a case of shake it off, and resume activity after it settles. But once it locked up during the shakeoff and felt like a nerve was being pinched between the bones - close eyes rolling on the floor kind of pain, unable to carry the foreleg to straighten or bend further. This subsided after about 30 mins of stillness and carefully straightening the knee while applying lateral pressure to the kneecap. I was then able to wrap it up and call an Ortho.

It’s basically killed any momentum for my fitness regimen, and I’m dreading the next episode.

MRI scan shows severe cartilege and kneecap wear, and a couple of loose bodies which we suspect may be getting lodged in sensitive areas, triggering the episode. Ortho plans to keyhole out the loose bodies, inject lubricating gel and recommends cartilege repair and stem cells on the site.

Anyone have experience with something similar? I’m ok with the keyhole and gel, but the repair job would put me on crutches for a month, only returning to athletic activity in 6 months, which I’m not keen on.

Any opinions/ advice?
