Exercise after your knee replacement is necessary to regain strength and function, the American Academy of Orthopaedic Surgeons. Physical therapy should be part of your recovery, but you will be required to do some activity and exercises on your own so you can get back to your normal activities. For cyclists, it will take time and patience to get back on your bike; follow your doctor's advice on the type and intensity of exercise.
Knee Replacement Surgery
Surgeons performed the first knee replacement in 1968, the AAOS reports; there have since been many medical advances with this procedure. For a total knee replacement, you can expect three components to be addressed: your femur, tibia and patella, or kneecap. The femur, or thigh bone, is cut or smoothed and covered with strong metal. The end of your tibia, or lower leg bone, is covered in durable plastic that fits with the metal on your femur. Often, the kneecap is replaced with a plastic replica so the muscles move and the knee functions normally. Recovery typically takes 12 weeks or longer depending on your physical condition and response.
Cycling
Cycling is a non-impact activity, so in that sense, it is OK after having your knee replaced. Stationary or indoor cycling is recommended once your recovery is complete. Cycling outdoors depends on your fitness level before the surgery and the terrain on which you ride. If you are an experienced rider, you will probably be able to cycle again. However, use caution when riding. Start on flat, even surfaces and ride only for short periods of time. See how your knee responds to light riding before increasing intensity. Discuss any questions or concerns with your doctor and/or physical therapist.
Things to Avoid
Just like a normal knee, the parts in your new knee can wear down. Take care to avoid repetitive activity that compromises your joint. For cycling, ensure that you are properly fitted to your bike, and that you pedal in a smooth, even manner to avoid undue stress. High-impact activities such as soccer, running or tennis are not advised. The load on your knee in a bent position puts more stress on its tibial component; do not use heavy resistance or loads in this position if possible.
Considerations
Discuss your concerns regarding cycling and physical activity with your surgeon before the procedure. Be detailed in the description of your rides so your doctor can give you a realistic view of post-surgery expectations. Because falling is a concern after surgery, you may not be able to ride outdoors until your physical therapy is complete. Do not rush your recovery. You may impede your progress and not get full benefit from your total knee replacement.
