Your knee, like mine, is part of a kinetic chain (the foot bone is connected to the leg bone, leg bone to the thigh bone, thigh bone to pelvic bone, etc.) and restrictions in joint movements above and below the knee may create extra stress on the knee joint and weaken the muscular control of the knee joint too. Ask around for a recommendation for a sports chiropractor in your area. They will be able to assess and treat the whole kinetic chain and provide appropriate exercises. When appropriate, I coach my patients in functional exercises such as, standing with piece of exercise tubing attached around one ankle with the other end of the tubing attached to the leg of some heavy furniture. Balancing on the free leg, pull on the tubing 8 - 12 reps then turn your body about 90 degrees and pull again, turn, and pull again until your have worked the muscles on all sides of your leg and hip. You'll discover that the stance leg really gets the workout. If the knee pain does not respond with any conservative therapies, you should consider a surgical approach. Hope that my .02 cents helps. I agree the LT at rest is a heavy bike.
