I have played squash and my wife is an orthopaedic surgeon. Per her, and from my experience, I can say that any serious squash is not easy on the joints (knees, ankles, thighs, hamstring, etc). I have done swimming, field-hockey, cricket and table-tennis (though not as a pro) and I can say this with a lot of confidence that Squash was the most intense even its in amateur/basic form. But if you're in it for fun e.g. play it 3 times a week for like 20 mins then maybe yes, but definitely check this with your doctor.
