Well, I tweaked the knee without an ACL at Timberline on a groomer in low visibility. Caught an edge and spun around to a stop. Binding popped but too slowly. No problem walking slow or driving home after resting a day after since my friend and I had booked a slopeside room for 2 nights. Timberline said I could even use the 2nd day ticket on my RFID card next season. Very well run operation.
Ortho urgent care PA had me push in all directions and confirmed it's just an MCL strain. X-ray only, no need for an MRI. Sent me home with PT exercises. I know them from knee rehab in 2012. Some are adductor/abductor exercises.
PA asked when I was going skiing again. Only told him about the early Feb trip to Taos. He didn't say anything. He knows my knee's history since it's the same ortho group I worked with for the ACL injury (no surgery).
Taking it easy for a couple weeks. ROM was almost normal after a week. Acupuncture helps a lot. Did a few turns on a green at Massanutten last weekend to confirm that easy skiing is not problem.
