I was a 73 year old male when I had double knee replacement surgery. I used a walker and a raised toilet seat following surgery. Both of these aids had small handles to grip for support and balance. After using them I found I had damaged the Ulnar nerve in both hands resulting in tingling and loss of strength in both hands and especially involving my small and ring fingers. This continued for fours months and I am still rehabbing the condition myself with exercise using rubber balls and a five pound dumbbell. I would recommend wrapping a towel around the handles to lessen the damage to the Ulnar nerve and avoid the damage. This will save you a lot of grief.View Thread
