TYPES OF KNEE PROCEDURES
Knee replacement surgery is actually a cartilage replacement. The knee itself is not replaced, only the cartilage on the ends of the bones. Knee replacement implants include a metal alloy on the bottom of the thighbone and polyethylene (plastic) on the top of the tibia and underneath the kneecap. The implant is designed to create a new, smoothly functioning joint that prevents painful bone-on-bone contact. Your surgeon may elect to replace all or part of your knee, depending on your condition and the extent to which your knee is affected by arthritis.
Total Knee Replacement Surgery
knee replacement, also known as a total knee arthroplasty, is a surgical operation performed to remove the degenerated and worn portions of the knee and reposition it into normal alignment. New components will be implanted into the knee to replace the worn-out bone and cartilage.
A total knee replacement repositions the knee into proper alignment and replicates the original function, allowing for a near-normal range of motion. Common reasons for undergoing knee surgery include severe pain, stiffness, chronic inflammation or degeneration that limits everyday activities; pain that interferes with sleep; and mild knee deformity such as bowing inward (varus) or outward (valgus). Although knee replacements provide excellent results and patient satisfaction, they are typically reserved for patients who have exhausted other options in order to minimize the need for future revision procedures to repair or replace worn components.
Partial Knee Replacement
Partial knee replacement (also known as Uni Knee Replacement) involves resurfacing the damaged portions of the knee while leaving healthy areas intact. The cartilage covering the femur and tibia becomes worn and the underlying bone develops spurs and various irregularities which produce knee pain and loss of knee motion. This procedure is most commonly performed on the inside (medial) section of the knee but in some cases it may also be performed on the outside (lateral) section of the knee as well.
The anterior cruciate ligament (ACL) is one of four ligaments that are crucial to the stability of your knee. It is a strong fibrous tissue that connects the femur to the tibia. A partial or complete tear of your ACL will cause your knee to become less stable and feel as though your knee is about to give out. There are a number of different graft options to replace your torn ACL. Your surgeon will select the option that is best for you.
We also treat a variety of other knee conditions such as Meniscus problems, Patella or Knee cap pain, and Synovial problems.
