A knee replacement, or a knee arthroplasty, is a surgery that replaces this weight-bearing joint when it has sustained significant damage. Surgeons typically perform this procedure to address severe joint deterioration, and they offer total and partial replacement options. During a total replacement, the surgeon replaces the entire joint surface with highly durable metallic and plastic components. A partial replacement only addresses the damaged portion of the knee, leaving healthy bone and cartilage intact. Here’s information on knee replacement and how surgery aims to restore fundamental joint mechanics:
When To Get Surgery
Individuals typically need this surgical intervention after non-surgical treatments, including options like structured physical therapy, anti-inflammatory medications, and localized cortisone injections, no longer provide adequate relief. Providers generally recommend knee replacement surgery when severe joint pain limits routine daily activities. Some health conditions that commonly cause joint deterioration include:
- Severe Osteoarthritis
- Rheumatoid Arthritis
- Post-traumatic Arthritis (From Recurring Injuries)
Chronic joint stiffness and persistent inflammation are also standard indicators that surgery may be necessary. Orthopedic specialists evaluate your comprehensive medical history, current mobility levels, and diagnostic imaging results to determine if surgery aligns with your needs.
What To Expect
A knee replacement surgery involves administering anesthesia before removing damaged cartilage and bone from the joint’s surface. The surgeon then attaches an artificial implant, restoring proper alignment and function of the knee. Initial recovery often involves a short hospital stay, but some individuals can return home on the same day.
Following surgery, patients typically experience localized swelling and discomfort, which are standard parts of the body’s natural healing process. Full rehabilitation takes several months and requires consistent effort and strict adherence to medical guidelines to restore joint function. You will likely use mobility aids, such as a walker or crutches, during the initial phases of your recovery.
How To Support Your Recovery
Active participation in your rehabilitation plan impacts the final outcome of your procedure, as following clinical guidelines helps protect the new joint. The RICE method, standing for rest, ice, compression, and elevation, is a standard recommendation for post-operative care. Resting the joint prevents unnecessary strain on healing tissues and developing muscles. Applying ice packs wrapped in a towel for short, measured intervals helps reduce localized swelling safely. Compression bandages provide external support, while elevating the leg above heart level promotes fluid drainage.
At-home Exercises
Restoring baseline mobility requires controlled, gradual movement throughout the day. Regular movement helps prevent joint stiffness, so your care team will recommend a daily exercise routine. Common early exercises include simple ankle pumps to promote healthy blood circulation and straight leg raises to engage the surrounding muscles without overloading the new joint implant. Performing these movements exactly as instructed prevents preventable complications and builds the foundational strength required for walking.
Physical Therapy
Professional physical therapy is a structured, mandatory component of joint rehabilitation. A licensed physical therapist guides you through targeted exercises that systematically increase your range of motion and strengthen the quadriceps and hamstrings. These outpatient or in-home sessions provide safe parameters for bending and straightening the knee as the tissues heal. Therapists also assist with gait training, allowing you to learn to walk correctly as you transition away from mobility aids.
