Hi Sharleen
I am 3 weeks post op moving onto week 4. I use a cane and also have a slight limp. My limp is actually my body releasing forward ever so slightly. I have PT 2 - 3x a week pending my schedule. What they are telling me is the following: (1) not all my muscles required to walk normally are recovered yet nor are they all firing, (2) the necessary muscles to walk properly are vastus lateralus (on your side), the glutes and a few others that attach into the pelvis and these have been affected by the surgery. They say this is all quite normal.
In addition to cycling (20 mins x2 daily), here is what I am doing daily as instructed by my PT. This is then followed by ICE.
(1) Place your injured side foot on a stair (as if you are about to walk up it) with the non-injured on the floor and push up and then back down. Try to contract your thigh and glutes. 20x or less as you work to 20.
(2) Same exercise as above but place the foot length wise on the stair and push up. You should feel this more on the lateral side. 20x
(3) Standing and with legs together, lift leg to the side. Do this for both legs. Switch off between them. Notice how difficult this is when you need to raise your good leg and support it with the one resurfaced. If you cannot do it 100%, use your hand to take some of the weight. Concentrate on contracting the front side of your pelvis and glutes. 20x
(4) Standing with legs together, raise leg up in front of you (with it bent at the knee). Again, switch. Concentrate on contracting pelvis and glutes. This will also help with range of motion. 20x.
(5) Stretch - hands against the wall with one leg forward and the other back. This works calf, hamstrings, and front of pelvis. Concentrate on top front of pelvis. Be cautious. Listen to your body.
A few final notes: start with less than 20 reps and work your way up. You will progress quickly. There are days when I am sore, and I then do fewer or just stop. I am doing the above 2x daily. I also ice when I have a free moment.
There seems to be no concesus on rehab. I am not a doctor. However, I see no reason why the above will not help you. That said, if one of these movements contradicts something that your doctor has said, DON'T DO IT THEN. Sorry, I had to state the obvious.
My discharge instructions and expectations indicate that I should be able to "ambulate without assistance aids" at 6 weeks. Some will be shorter or longer... but it sounds like you are progressing. I think that it is the mentality of those being resurfaced - a bunch of Type A's ready to get back at life.
Good luck... resurface
