PCL tears don't always require surgery the way ACL tears do. It really all depends on how unstable your knee feels during activity or even walking and any other soft tissue damage there may be (ie meniscus tear). ACL tears are usually more worrisome, but if you are having a great deal of buckling or feeling like the bones are shifting when you walk or ride, surgery may be your only option for a normal life. Once you tear your ACL of PCL, the ligmanet does not grow back as with the collateral ligaments. I am not as well versed in PCL reconstruction surgery, so I don't know as much about the recovery process.
I personally have been dealing with an ACL tear for years. It started as a partial tear from a rugby injury almost 10 year ago, but a couple horseback riding accidents have made it worse to the point where I have to wear a rather heavy duty brace when I ride. I have also ruptured and retorn my MCL in the process so I have more instability from that injury. The riding itself hasn't been much of an issue. If fact the riding has strengthened the muscles around my knee and hip joints. However, I've really tweaked my knee bad to the point of being laid up for months just from a horse tripping or bucking. It doesn't take much for it to literllay "pop" out, hence the brace when I ride "just in case". Last year I retore my MCL and had a stress fracture from riding out a bucking horse. I've also had to modify my active lifestyle. I can still jog with a special brace, but I am limited in how far I can go without really compensating how I run and I can't play sports any more such as soccer and rugby, but I have just learned how to live with running at the 5K level and hiking in moderation. As long as I can still ride, I am just going to hold off surgery. I'm not trying to be a hero or anthing. I just know it's a LONG rehab process, something I neither have the time for, nor can afford right now, especially since I just had a baby and have those medical bills to deal with.
Good luck. If you opt out of surgery, make sure to get into physical therapy to build up the muscles around your hips and knees to make you as stable as possible and avoid damaging the cartilage further.
