Arthritis is a ***** !

Had a left knee total replace a few years ago. Had it done in early January and was back bowling in early April.
As others have said, take the PT seriously and do EVERYTHING they tell you to do. Not more, but certainly not less. Only thing that's still a bummer is I can't kneel on it, run or jump. Not being able to kneel makes it a real ***** trying to get back standing after working under my Dart.
