At physio with my first knee I was quite puzzled that other KR patients were whizzing along on the exercise bikes yet I, the one who had loved spin classes, couldn't get the wretched pedals to rotate. Bonesmart members at a similar stage were cycling merrily too. Not me. Horror of horrors - it took me, the sporty strong one from a family of cyclists, six weeks of pathetically rocking the pedals back and forth until, yippee, they went right around!
Lesson learnt - my knee had its own healing agenda too.
The left knee should have been operated on 4 months later but family circumstances meant it wasn't and the left knee's continuing deterioration meant I was unable to push my new knee too hard exercise wise - but it was working really hard to support the mangled left one.
I was very concerned that I had missed the boat in strengthening and gaining flexibility in my PKR and felt it possibly wouldn't and couldn't now happen.
Yet it did!
I feel my improvement was ridiculously simple - due to exercising in a supportive medium - water - and exercising using a variety of workouts quite vigorously but not to the point of muscle or joint fatigue. I listened carefully to my joints - the new one and the old one. I went carefully and steadily - not too much pushing but gave myself a solid work out and was able to use movements in the water that are unsustainable on land. (Id done quite advanced water workout classes in the past.)
I built up my quads of course, knowing that would provide good all round support after my next PKR and did stretching exercises too. The water provided enough resistance. Slowly but surely I found flexibility increasing greatly. Im delighted.
I didn't think Id ever get a good hamstring stretch again - but its suddenly there!
Im not chomping at the bit to get in the water with my second new knee. Im prepared to give it time so Im off to physio today and will be looking to maybe push a bit in the water at the 6 month mark. I think for me that will be good. I have observed that we are all so different in our healing and that listening to our body is essential.
Slow gradual gains are good. Im sure that knee of yours is still healing steadily and will heal really well as you have youth on your side - a great benefit for regeneration of tissue, bone, muscle etc.
It looks to me like you are doing pretty well - hiking, cycling etc. Might it be that working really hard at the strengthening was stressing the healing process? I can understand how keen and determined you are to get back to normality and be able to forget about that PKR of yours. In another 6-12 months I'm sure that will be the case. Be patient my friend - it will come good for you.
