Chronic joint discomfort can be such a pain, making everyday activities like walking, climbing stairs and even standing unbearable. When primary treatments such as medication and physiotherapy no longer work, hip and knee replacement surgery is the next step. Medical professionals often suggest this procedure as the most efficient way to recover mobility and minimize pain.
As populations grow older, joint condition cases like osteoarthritis rise as well. In turn, the number of hip and knee replacement procedures continues to add up across the globe.
In this article, we will explore everything relating to this transformative surgery. This includes key statistics, trends, and the cost from different sections of the world. In this way, novices and experts alike will better understand the growing role of this procedure in modern healthcare today.
What is Hip Replacement Surgery?
Hip replacement surgery is an operation that replaces the damaged hip joint with an artificial implant.
Also called hip arthroplasty, surgeons usually recommend it for patients experiencing limited mobility and severe pain. Most people who suffer from osteoarthritis, rheumatoid arthritis, or hip fractures have this option as a last resort.
How Does Hip Replacement Surgery Work?
The surgeon swaps the damaged ball from the top of the femur (thigh bone) with a ceramic or metal one. They insert the stem of this artificial sphere into the bone itself. The next step is replacing the damaged cartilage and bone in the hip socket with a lined prosthetic socket. The lining is a combination of ceramic and plastic for ease of movement.
When all the prosthetic components are in place, it works remarkably like an organic hip joint. Specialists design these implants to restore unimpeded joint movement, easing pain and reclaiming mobility for everyone who needs it.
What is Knee Replacement Surgery?
Knee replacement surgery is an operation that replaces a worn-out or damaged knee with an artificial implant. Knee specialists recommend this procedure for individuals who experience the following knee complications:
- Severe knee pain
- Osteoarthritis
- Rheumatoid arthritis
- Permanent knee injuries
How Does Knee Replacement Surgery Work?
The surgeon’s focus is the removal of the injured surface of the knee joint, composed of worn-out cartilage. They also carefully extract the tips of the tibia (shinbone) and femur (thighbone). The metal and plastic components that replace it recreate the damaged part artificially. They also give way for a durable plastic spacer which allows the joint to move with no trouble.
The entire procedure usually lasts 1-2 hours while the patient is under general or spinal anesthesia. And, like many other prosthetics, specialists create these knee replacements to mimic the pain-free motion of a regular knee.
Hip and Knee Replacement Surgery Global Facts and Trends
Hip and knee replacements are actually one of the most common operations around the world. Apart from that tidbit, here are other facts and trends that can help highlight how these procedures aid patients:
- Between 2019 and 2025, there were 63,000 hip replacements and 94,000 knee replacements in Canada alone. It gave a grand total of 199,470 surgeries in a little over 5 years. (CIHI, CJRR)

The Risks of Hip and Knee Replacement Surgery
Hip and knee replacement surgeries are highly effective and safe operations. Despite that, these are still major surgeries. And like any other major surgery, they carry a certain amount of risk. Any patient should review these potential complications in order to make their own informed decisions. These risks include the following:
- Infection: the incision site or the location of the implant can develop an infection, albeit rare. It requires additional treatment or surgery to address it.
- Blood clots: DVT (deep vein thrombosis) is a possibility around the legs after the surgical procedure. It should be treated immediately to avoid any further complications.
- Implant wear: Artificial joints can wear out or loosen over time. You can follow-up with your physician to determine whether revision surgery is necessary.
- Nerve or blood vessel damage: any surgery can lead to injuring surrounding nerves or blood vessels. This may lead to circulatory issues like numbness and weakness.
- Persistent pain or stiffness: Even with successful surgery, you can still feel discomfort or reduced range of motion
- Dislocation (for hip replacements): The initial recovery period is the phase when you can see if your hip joint will stay put or not. Otherwise, it might lead to the dislocation of the new hip replacement.
Recovery Process After Hip and Knee Replacement Surgery
Apart from reintegrating daily activities, the recovery from hip and knee replacement surgery also involves intensive physiotherapy and hospital care. The recovery process should start right after surgery, and most patients begin immediately.
Progress post-op will rely heavily on factors such as overall health, age, and the type of surgery. Typical recovery for people who have had hip and knee replacement surgery are as follows:
- Hospital stay: Patients stay at the hospital for 2-5 days after surgery. During this time, nurses go over wound care, pain management, and initial mobility exercises for the patient.
- Early mobility: Walking with the help of a walker or crutches usually begins within 24 hours. This prevents complications such as blood clots and promotes healing.
- Physiotherapy: Specialized exercises will help rehabilitate the patient, restoring their flexibility, range of motion, and strength. This will last 6-12 weeks or longer, depending on the doctor’s advice and the patient’s progress.
- Daily activity resumption: Most patients can gradually return to normal activities like walking, climbing stairs, and light household tasks within 6–12 weeks. Medical professionals discourage high-impact activities for several months.
- Full recovery: Most individuals expect full recovery within 3-6 months or up to a year after surgery.
Hip and Knee Replacement Success Rates
Success rates for such effective procedures as hip and knee replacement surgery are high around the world. The following rates reflect the advances in implant quality, surgical technique, and post-operative care:
