The surgical procedure of knee replacement (knee arthroplasty) involves replacing parts of damaged or deteriorated knee joints with artificial parts made of plastic and metal to alleviate pain and improve knee function. It’s most commonly used to treat pain and stiffness in the knee joint caused by osteoarthritis. Depending on the damage to the knee, it can be used to replace all of your knee joint (total knee replacement) or some of it (partial knee replacement).

The first surgery of this type was performed in 1968. Since then, improvements in materials and surgical techniques have greatly increased its effectiveness. Before the procedure, the specialists will evaluate the knee’s strength, stability, and range of motion, and will use images to assess the extent of damage, to determine if knee replacement is the appropriate option. The choice of joints type and surgical techniques is based on several factors such as age, weight, activity level, knee size and shape, and overall health.

Knee Osteoarthritis (Gonarthrosis)

The most common disease that leads patients to undergo knee replacement surgery is knee osteoarthritis.

It is a condition characterized by joint pain, inflammation, and stiffness. It commonly affects the knees, which are the largest and most powerful joints in the body. Knee arthritis can be a severe and disabling condition.

The primary goal of undergoing a knee replacement procedure is to alleviate pain and enhance mobility, ultimately improving one’s overall quality of life. While some may believe that the completion of a successful surgery marks the resolution of the issue, it’s crucial to recognize that surgery alone is only a part of the solution. Despite the surgeon’s skillful efforts, the patient plays a pivotal role in maximizing the benefits of the surgery. Following the prescribed physical therapy regimen is imperative for a successful recovery.

Rehabilitation serves as a key component in expediting the return to a normal, independent lifestyle over the long term. It addresses pain relief, strengthens the muscles surrounding the joint, enhances stability, aids in fall prevention, promotes blood circulation, and manages swelling. Surprisingly, initiating the rehabilitation process on the day of surgery completion, once the patient has recovered from anesthesia, is considered optimal. The typical rehabilitation program spans three weeks, after which the patient can continue exercises at home.

Deviation from the prescribed physical therapy plan may lead to an extended healing period, potential injuries to the new joints and supportive muscles, and an increased risk of future revision surgery. With diligent adherence to the rehabilitation program, most patients can enjoy a pain-free life approximately six months to a year post knee replacement surgery.
