I’ve had both knees replaced, ten years apart. I am not young.
in my experience one absolutely must do the exercises. They are extremely painful to do, extremely painful, but if they’re not done the consequences means the NHS have wasted thousands on the patient! Take pain relief regularly but wean off as soon as possible. I hardly took any.
Think of the internal workings of the knee as being like wall paper paste. It’s loose and slack but if you leave it to stand it thickens up and is difficult to work with. That’s what happens to the knee. Everything has been disturbed, tendons, muscle etc and need exercise to stretch them and get them back in shape. It’s a killer!
On discharge after 2 nights in hospital, I could manage, with care and my crutches, to do the stairs. I could move around and make simple food before I needed to rest. Ready meals, sandwich and tinned soup. It was massively painful to bend legs to lower onto the toilet! Breath through it, like childbirth!
Ice packs were my saviour. After any exercise in house or elsewhere, I put feet up frequently and wrapped ice packs around knee. You can buy the knee wraps from Amazon. They bring massive relief.
I was out in the fresh air outside my house within 4 days of discharge, walking with crutches in the lane outside. I walked with crutches along a sea front on my 10th day. Not far, not fast, accompanied by my partner.
So, with care and determination and the exercises, it will quickly restore pain free mobility. I am now at the gym x3 per week and I regularly swim. I’m not young.
It will be wise to press the medics for aftercare/carers availability but if the patient is not feeble of mind, they won’t starve because they must get up out of bed or chair and use that knee to move around!
Mind over matter. Mind over matter. Feel the pain and do it but dont over do it!
