Ok - however, everyone's body is different and you want to take it easy. The first 3 - 6 months are key, even if you're in great shape.
There's nothing to say you can't go back to working out, but full blown martial arts training might take a bit. Patience is the key. There's several of us martial artists at different stages of life and recuperation, but some issues you want to watch:
- The first three months your bones are recovering from the surgery. The biggest risk during this time is neck fracture, which would require a revision. The reason I've heard is that there is blood loss to the area that needs to be replenished in a poorly vascularized(SP?) area.
- The big muscles may be rarin to go, but your concern is the smaller supporting muscles. Those have been compromised by the surgery, and need to heal. In martial arts, especially kicking and pivoting, they need to be strong.
- ROM. You know that many kicks require good ROM. You don't want to try some kick and wind up on your butt because you're tight. Not only is it a fall, but you make the rest of us martial artists look bad and lose street rep. Not good.
- Stamina. You need to build it up, as you lose it during a workout, your bigger muscles will lean on your smaller ones, which are weaker from the procedure. It's how people wind up with secondary problems like bursitis and muscle pulls (illeoapsis muscle for example)
- It took me a good three to four months to go through PT (in house, out house... I mean outpatient), and during that time, I devoted myself to those exercises as intensely as I did martial arts exercises.
- Talk to the PT about your goals. I told her I wanted to get back to hands work first, then kicking, etc. She designed a workout regimen to work towards that, but I lightened up and didn't put a time limit to it.
- Take it easy on the return. Gary2010, Chris Finn, Nemesis and several others are experienced martial artists who have done this, use their advice.
- Stretching. This took the longest for me (about 6 months before seeing good progress), you may need less, but remember that when you do this you're putting stress on the joints. Patience on this is paramount.
I'm about to celebrate my year anniversary on my last hip (14 months on the other), I'm back to full bag training on the upper body, the stretching is going nicely now, but it took about 6 months before I saw real progress. Kicks are at waist level, can do roundhouse full power, side kicks at low altitude, front kicks waist level full power. Have not done them on the bag.
I'm 54, 38 years of martial arts, got my TKD black belt about 25 years ago. You're younger and will heal faster, but bones are not forgiving, so be aware and you can make a great recovery. I trust Dr. Snyder, but he is not a martial artist and may not be fully aware of the stresses we put on the body. I got back to weight lifting (moderate amounts) long before I could handle a full bag session.
Sorry if I got wordy, but I think it's important to take good care of yourself so your recovery goes great.
