If you are having trouble getting muscle back after surgery, or just building it up to help your joints, you should be aware that the high level of cortisol in your blood that stress and anxiety cause is going to cause your muscles to break down. Cortisol converts muscle protein into glucose. Work on getting your emotions under control, be happy, and you will probably see an improvement in your muscle rehab. Knee surgery and the inherent long recovery can present some challenges. Let those around you know the importance of a good mental outlook for getting better, so everyone can support you. Cheers.
