A total knee replacement or knee arthroplasty, is a common surgical procedure performed on patients with severe knee pain that limits their mobility caused by arthritis or injury. These advanced knee joint issues cannot be managed with medicine or physical therapy. The surgery involves removing all damaged cartilage and bone and replacing them with an artificial joint made of metal and plastic components.

What is Total Knee Replacement Surgery?
A procedure known as total knee arthroplasty, or total knee replacement surgery replaces the damaged surfaces of the knee joint with artificial components. The surgery is recommended for patients suffering from severe arthritis, especially osteoarthritis, or significant knee joint damage due to injury or degenerative conditions. When the cartilage that cushions the bones in the knee wears away, bones may begin to rub against each other, causing pain, swelling, and restricted movement.
A primary total knee replacement involves the complete replacement of the entire knee joint with a prosthetic, usually made from metal, plastic, or ceramic material. It nearly replicates the movement of a natural knee. So, that results in significantly reduced pain and improves the patient’s ability to move. Doctors typically recommend knee joint replacement when other treatments, such as medication, physical therapy, or less invasive surgeries, have failed to relieve pain or improve mobility.
When is Revision Knee Replacement Needed?
A revision knee surgery becomes necessary when a previously implanted knee replacement begins to fail or causes severe discomfort. Even though a primary total knee replacement is meant to last for many years, some circumstances may require a second surgery known as revision total knee replacement. This procedure replaces a knee replacement that has become loose, worn out or shifted. These issues may occur due to infection, degradation from normal wear and tear, or problems that developed after the initial surgery.
Common reasons for needing revision knee surgery include:
- Implant wear and tear over time
- Instability or loosening of the implant
- Infection around the joint
-Continuous or significant pain after primary surgery
-Stiffness or decreased range of movements of the joint
Revision knee surgery often results in a much more complicated process than the initial surgery and requires a very experienced surgeon to ensure proper correction and restoration of knee function.
Primary vs. Revision Knee Replacement Surgery
Both total knee replacement and revision knee surgery procedures aim to restore the knee's functions and make it free from pain, however, each possesses many differences concerning complexity, duration, and recovery.
Primary Total Knee Replacement:
A primary total knee replacement is a first-time surgery where the damaged parts of the knee joint are replaced with artificial components. It is typically a well-planned procedure with a high success rate, often lasting 15-20 years. Recovery from primary surgery usually takes several weeks, during which patients undergo physical therapy to regain strength and mobility.
Revision Knee Replacement:
A revision knee surgery procedure is performed when the initial knee replacement has failed or is causing issues due to various reasons, such as pain, instability, or infection. It is a more complex procedure because the surgeon has to remove the old implant, assess the bone and tissue surrounding it, and then have to place a new prosthetic joint. Surgeons commonly face difficulties such as bone loss, scar tissue, or joint instability during this procedure.
Complexity: Revision surgery is more complex due to factors such as bone deterioration, scarring, or previous surgeries. It requires specialized techniques and planning compared to primary knee replacement.
Duration: Revision surgery often takes longer than a primary knee replacement, as it involves more detailed work in removing old implants and rebuilding the joint.
Recovery: Recovery after revision knee surgery can sometimes be hard because longer periods are required to regain strength and functionality. Patients often ask, "Is revision knee surgery more painful?" Revision surgeries are usually more painful at the initial stage due to the complex procedure and the condition of the surrounding tissue. However, pain management techniques and proper rehabilitation ensure good results.
Total Knee Replacement Surgery Procedure
A procedure of total knee replacement surgery involves several critical steps that include the removal of the damaged parts of the knee joint and the replacement of these parts with prosthetic components so that patients regain pain-free mobility. Whether it is primary knee replacement or revision surgery, it is well-planned and executed by an experienced surgeon. The following is a detailed procedure for both types:
Primary Total Knee Replacement Procedure:
Preoperative Preparation: Patients are usually assessed before **knee replacement surgery**, including their medical history, and physical exam with imaging tests like X-rays or an MRI to determine the amount of damage done to the knee joint.
Anesthesia: The patient is either given general anesthesia, causing the patient to become completely unconscious, or regional anesthesia, where the patient remains free from pain but the lower half of their body goes numb during the surgery procedure.
Incision and Exposure: The surgeon makes an incision, typically 6 to 10 inches long, to access the knee joint. The kneecap (patella) is moved aside to expose the joint surface.
Bone Preparation: The damaged cartilage and bone from the femur (thigh bone) and tibia (shin bone) are carefully removed. Special tools are used to shape the bone surfaces to ensure a perfect fit for the new prosthesis.
Implant Placement: Metal components are attached to the prepared bone surfaces using bone cement or other bonding agents. A medical-grade plastic spacer is placed between the metal components to create a smooth gliding surface, simulating natural knee movement.
Final Steps: The kneecap may also be resurfaced with a plastic implant, if necessary. After positioning the prosthetic components, the surgeon tests the knee for stability and range of motion. The incision is closed with sutures, and a sterile dressing is applied.
Recovery: After surgery, patients are monitored in the recovery room before being moved to a hospital room. Physical therapy typically starts within a day or two to promote mobility.
Revision Total Knee Replacement Procedure:
A revision knee surgery follows similar steps but involves additional complexities:
Preoperative Assessment: The surgeon evaluates the failure of the original knee replacement, whether due to loosening, infection, or wear. Imaging tests help identify the condition of the surrounding bone and tissues.
Anesthesia: As in primary surgery, anesthesia is administered to ensure the patient is comfortable and pain-free.
Removal of the Old Implant: The surgeon carefully removes the old prosthesis and any cement used in the first surgery. In cases of infection, infected tissue may also be removed.
Bone and Joint Reconstruction: Additional steps may be necessary to rebuild the joint. Bone grafts or metal augments might be required to replace missing or weakened bone around the knee.
Placement of New Implant: The new prosthetic components, which may be larger or more complex than those used in a primary replacement, are carefully placed. A spacer is inserted to maintain smooth movement of the joint.
Final Steps: The surgeon tests the joint for stability and function before closing the incision.
Recovery: Recovery from revision surgery may be longer due to the complexity of the procedure. Patients may experience more discomfort initially but will work with physical therapists to restore mobility over time.
Patients undergoing a surgical knee replacement can expect to stay in the hospital depending on the type of surgery. Physical therapy begins soon after the operation to aid in recovery. While both procedures aim to relieve pain and restore function, revision total knee replacement may involve a longer and more challenging recovery process due to the nature of the surgery.
Types of Knee Replacement Surgeries
There are several types of knee replacements designed to address various levels of knee damage and patient needs. Each surgery aims to restore knee function and relieve pain, but the extent of the replacement and complexity varies.
Full Knee Replacement (Total Knee Replacement)
Also known as complete knee replacement or full knee replacement surgery, this is the most common type. It involves replacing the entire knee joint, including the damaged cartilage and bone on both sides of the joint (femur and tibia), and sometimes the kneecap. A prosthetic joint made of metal and plastic components is used to replicate the movement of a natural knee.
This surgery is typically recommended for those with severe arthritis or extensive knee damage that affects most or all of the joints. It significantly reduces pain and improves mobility for the majority of patients.
Partial Knee Replacement
In a partial knee replacement, only the damaged portion of the knee is replaced, leaving healthy cartilage and bone intact. This procedure is less invasive than a full knee replacement, resulting in a quicker recovery and less postoperative pain.
Partial knee replacement is ideal for patients with arthritis or damage confined to one section of the knee. However, it’s not suitable for everyone, particularly if the damage extends beyond a single part of the joint.
Revision Knee Replacement
A revision knee replacement is performed when a previous knee replacement has failed or worn out. This procedure is more complex, as it involves removing the old implant and replacing it with a new one. Surgeons may also need to address complications such as bone loss, scar tissue, or instability.
Revision surgery is necessary when patients experience continued pain, instability, or issues with the original implant, such as loosening or infection. It typically requires longer recovery than primary knee replacements due to the complexity involved.
Each of these types of knee replacements addresses specific knee conditions, helping patients regain mobility and reduce pain based on their unique needs.
Recovery after a total knee replacement surgery is a gradual process that requires a commitment to physical therapy and proper care. While each patient’s healing varies, understanding the general knee replacement recovery time can help set realistic expectations. Here's a breakdown of the typical recovery timeline, rehabilitation tips, and what to expect in terms of mobility and pain management.
Recovery Timeline
First Week After Surgery:
- Patients are encouraged to begin walking with the aid of a walker or crutches within 24 hours of surgery.
- Swelling and pain are common, and pain management will include medications and ice therapy.
- Light physical therapy exercises begin in the hospital to improve movement and prevent stiffness.
2-6 Weeks Post-Surgery:
- By this time, patients can walk more independently, often with the help of a cane or walker.
- Physical therapy continues regularly to strengthen the knee and improve flexibility.
- The knee surgery recovery time during this period will involve gradually resuming daily activities, though full mobility is still limited.
6-12 Weeks Post-Surgery:
- Patients usually see significant improvement in mobility and pain levels.
- Most can resume moderate daily activities, such as walking without assistance or climbing stairs.
- At this stage, physical therapy helps patients regain full range of motion and strength.
- For many, the healing time for knee replacement falls within this window, with most resuming normal activities.
3-6 Months Post-Surgery:
- Most patients return to normal daily routines with minimal pain.
- Light recreational activities, such as swimming or biking, can be reintroduced.
- Full recovery and recuperation time for knee replacement varies, but it often takes 6 months to a year for the knee to feel fully functional.
Rehabilitation Tips
Stick to Physical Therapy: Regularly attending physical therapy sessions is key to regaining knee strength and flexibility. Exercises focus on building muscle strength and restoring knee motion.
Follow Doctor’s Instructions: Adhering to post-op care, including keeping the incision clean and taking prescribed medications, is crucial for proper healing.
Gradually Increase Activity: It's important to take it slow during recovery. While light walking is encouraged early on, strenuous activities should be avoided until cleared by a doctor.
Use Assistive Devices: A walker or cane can help with balance and reduce the strain on your new knee during the initial recovery period.
Mobility and Pain Management
Mobility: Early on, patients may need help walking and moving around, but mobility improves steadily over the weeks. After 6 to 8 weeks, most people can walk independently and perform daily tasks without significant discomfort.
Pain Management: Pain is common but manageable. Doctors prescribe pain medication, and ice therapy can reduce swelling. As healing progresses, pain typically decreases, and patients can gradually switch to over-the-counter pain relievers.
While the knee replacement recovery time varies by individual, most patients experience a significant improvement in knee function and pain relief within 3-6 months, with full recovery taking up to a year. The key to a successful recovery is staying active within the limits advised by your doctor and therapist.
