Joint Replacement Surgery: What You Need To Know

Joint replacement surgery is a life-changing procedure for many individuals suffering from chronic joint pain and limited mobility due to arthritis or injury. As the average age of our population increases and the demand for these surgeries grows, patients need to be well-informed about the process and what to expect before, during, and after the operation.

By understanding the process and being well-prepared, you can make informed decisions and optimize your recovery journey.

Understanding Joint Replacement Surgery

Joint replacement surgery, also known as arthroplasty, is a surgical procedure that involves removing a damaged joint and replacing it with a prosthesis. For anyone suffering from joint disorders, such as osteoarthritis and rheumatoid arthritis, this surgery helps alleviate pain, restore function, and improve their quality of life.

Most people undergo this surgery after conservative treatment options like medication or physical therapy have been exhausted. The surgeon often determines the extent of joint damage and whether the patient is a suitable candidate by evaluating their medical history, performing a physical exam, and through X-rays or MRIs.

Common joints replaced are the knee, hip, and shoulder, although other joints, like the elbow and ankle, can also undergo this procedure.

Risks and Complications: The Importance of Quality Control

Like any other surgery, joint replacement surgery carries potential risks and complications, including infection, blood clots, nerve damage, and implant failure. Patients need to be aware of issues related to medical devices as well. The infamous Exactech lawsuit underscored the significance of quality control and proper packaging for joint replacement implants. Thousands of patients with faulty Exactech implants had to undergo revision surgeries due to early implant failure, emphasizing the need for patients to research their chosen medical device manufacturer carefully.

It’s important for patients to talk openly with their surgeon and carefully follow post-operative instructions to reduce potential risks and complications. Additionally, following a rehabilitation program that includes physical therapy can help promote a successful recovery and maintain long-term joint health.

Types of Joint Implants: Materials and Design

Joint replacement implants come in various materials, including metal, ceramic, and plastic.

Metal-on-metal (MoM) implants consist of a metal ball and socket, while ceramic-on-ceramic (CoC) implants are made entirely of ceramic. Metal-on-plastic (MoP) implants have a metal ball and a plastic socket, and ceramic-on-plastic (CoP) implants feature a ceramic ball and a plastic socket.

Implants also differ in design, with some being fixed-bearing and others being mobile-bearing. Fixed-bearing implants have a stationary polyethylene insert, while mobile-bearing implants allow movement between the insert and the implant components. The surgeon will consider factors such as patient age, activity level, and joint condition when selecting the most suitable implant type.

Surgical Approaches: Traditional vs. Minimally Invasive

Traditional joint replacement surgery involves a single, long incision to access the joint, remove damaged tissue, and implant the prosthesis. In contrast, minimally invasive joint replacement surgery uses smaller incisions and specialized instruments, resulting in less tissue disruption and potential benefits like reduced post-operative pain, faster recovery, and shorter hospital stays.

However, minimally invasive surgery may not suit all patients or joint conditions. The surgeon will determine the best approach based on factors such as patient age, overall health, and the extent of joint damage.

Preoperative Planning and Preparation

Patients undergo a series of preoperative tests and evaluations to identify any underlying conditions (such as anemia or diabetes) that need to be addressed before surgery.

Plus, it’s always helpful to consult with your medical examiner and check if medications may need to be stopped or adjusted. Patients must follow all preoperative instructions to ensure successful results and minimize risks.

The Day of Surgery: What to Expect

Patients undergoing surgery are required to arrive at the hospital several hours before the scheduled procedure. They will be administered preoperative medicines, and the surgical area will be disinfected to reduce the chances of infection. To ensure safety and comfort, patients will be given anesthesia during the surgery.

The surgeon will perform the surgery by making cuts, removing the damaged joint surfaces, and putting in the selected prosthesis. How long the procedure takes depends on which joint is being replaced and whether additional procedures, such as bone grafts or repairing soft tissue, are needed.

Post-operative Care and Recovery

After surgery, patients will be closely monitored in the recovery room until they are stable and awake. Pain management will be a priority during this time, with medications administered as needed. Patients will usually stay in the hospital for several days, during which time they will begin their rehabilitation program, including physical therapy exercises and walking with assistance.

Upon discharge, patients will receive instructions for at-home care, including wound care, pain management, and activity restrictions. They should continue their rehabilitation program and gradually increase their activity level as advised by their healthcare team.

Rehabilitation and Physical Therapy

Rehabilitation is a crucial component of the recovery process after joint replacement surgery. Physical therapy will help patients regain strength, flexibility, and function in the affected joint. The specific exercises and duration of the rehabilitation program will depend on the type of joint replaced and the patient’s individual needs.

Patients should work closely with their physical therapist to develop and follow a personalized rehabilitation plan. Consistently attending therapy sessions and performing prescribed exercises can escalate the chances of recovery.

Long-Term Outcomes and Implant Lifespan

Most surgeries are successful and result in reduced pain and improved function for patients. The implant’s lifespan depends on several factors, including the patient’s age, activity level, overall health, and the type of implant used. Typically, joint implants last between 15-20 years, but newer implants might last longer. Patients should be aware that if the implant wears out or complications arise, revision surgery might be required.


If you have joint pain and mobility problems, joint replacement surgery can improve your situation and enhance your quality of life. However, before going for surgery, research various procedure types, learn about the surgery, and understand the significance of post-operative care and rehabilitation. The success of your recovery relies on your dedication to rehab, maintaining a healthy lifestyle, and adhering to medical
