I don't know, it would depend on if the sling put any pressure on the knee or bent the leg, or put it in a position that's not good for it while it heals. When he starts walking again, the surgeon only wants them to walk a straight forward motion, no sideways motions until he's cleared for normal activity. Sideways could potentially tear the monofilament before it heals. It also hurt Columbo to bend his knee at first. That came slowly as he got stronger (walking, exercises). I'd ask the surgeon his opinion about the sling. Also, Buster Brown is correct about the worry of him falling out. A fall during the healing process probably wouldn't be a good thing. It's a cute sling, though.
