Not sure but I just had cmc surgery Nov30 but not implant. Surgeon took the arthritic bone out took apiece of tendon from my forearm to put in its place. I watched a you tube video of an actual surgery before having done. Hand surgeon had me do 6 weeks of therapy prior to strengthen thumb and hand. Said it’s 4 month recovery. Am now 6 weeks into recovery. To date has been a picnic compared to my RTS and TKR. I was on anti inflammatory for first 5 weeks. Hope things continue to improve. I have been cleared to now do all my RTS and TKR exercises. Jury is still out for me but I think I’m doing well.
Just you tube surgery you want to see. Asked my surgeon about implants vs tendon surgery, he said there was a lot of failure with implants so this is how they do it now. He is a young hand surgeon.
Best of luck
