@callie642 - slower healing just seems to be something we have to accept at our older age. Seems like any bump or bruise looks worse than it is and takes longer to heal.
About the only thing you can do is make sure you have a healthy diet with extra calcium and vitamin D and maybe other supplements. Before my recent TSR, the nurse giving the pre-op presentation stressed that it was important to eat lots of protein during the healing process to aid the damaged muscles in repairing themselves. The easy change I made was for breakfast, eating more eggs instead of always my usual oatmeal.
