SC Joint Surgery/ Resection Arthroplasty

Has anyone undergone a bone resection/arthroplasty before? I had a fall a year ago and messed up shoulder at the SC joint, where the clavicle meets the sternum. I’m having surgery to essentially shorten my clavicle so the two bones don’t grate on one another and cause early arthritis and pain. Has anyone experienced this type of surgery before? What was the recovery timeline like? There’s no soft tissue or ligament involvement (not reconstructing the ligaments). I asked what a realistic timeline is and my ortho just said I’ll have to take it easy for a couple months. So like only ride one horse a day? I’m young and otherwise super healthy with great mobility and strength. I had knee surgery and was back to full work/sports about 2 months ahead of schedule doing all my own rehab. I feel a bit like an anomaly discussing this with my ortho because I don’t think I’m the “normal” patient. TIA!
