As someone who did arthroscopy long ago. Staying not active is the worse thing you can do to yourself. With no running, jumping, etc... Comes even more muscular imbalance and pain creeps to the thighs, ankles, lower back....
In addition, being inactive translates to high blood sugar, high cholesterol, fatty liver and heart problems.

I suggest you search for GotROM and UprightHealth. They got the real solution dialed in and saved my life after the arthroscopy solved some but not all issues.
