I had to wait six months before arthrolysis. My DR. was concerned about infection. Outpatient, lasted about two hours because there was so much scar tissue. Aggressive PT (I even used my exercise bike for 10 minutes every three hours, set the alarm during the night). I had an MUA scheduled, Dr. wanted to scope me and if he found a lot of scar tissue he would perform lysis. Well, he found a lot of scar tissue and told my wife, while I was still under, that there was no way I would have broken through all that myself. Got 110 right away, had to work hard to get to 120. Some of the scar tissue has come back after a year.
