If you don't have persistent mechanical symptoms (locking, catching, the knee giving out, etc.) I would not go for a surgical consult. It sounds like you just did too much dancing and flared your knee up. If that is the case this is something that needs rehab and not surgery. Also, I would expect to find some abnormalities in the knee cartilage of a 57 yo man, regardless of whether their knee hurt or not. I would just start back training extra light on squats and build back up. If you are still missing some knee flexion try some pin or box squats and gradually increase the ROM over time.
