Hi,
Thank you for providing the brief history of you.
A thorough clinical examination is advised. As your age is 69 years and also the TKR was done, now facing with
back pain and also swelling of the leg, it is totally related to the overall body non-conditioning.
As body is a single
unit the conditioning of the body is of importance to balance the systemic requirements.
Now coming to TKR - you should have continued your TKR
rehabilitation program as by which you must have been helped more than even thought.
The exercises post TKR are helpful to make the muscle stronger not only of the knee but also of the over body when we talk about rehab.
If you were only performing TKR operated leg than the rest of the body needs an attention.
Since you have a back ache, again,
physical therapy is of the choice to help you out. Core stability is what needed.
Also, for
swollen ankle, you need to have a check for your heart and your vascular system. As due to weakness of both the swelling can occur frequently.
In my clinical practice, patients post TKR undergo 16 weeks to 24 weeks of rehabilitation program for not only the TKR procedure but also for the overall body conditioning. And majority of them recover to the maximum.
