Joint replacement surgery is safer, more effective and more personalized than ever before.
Advances in surgical techniques, implant materials and recovery protocols have transformed what used to be a last-resort procedure into a viable option for adults of all ages. Today’s artificial hips and knees are designed to better match natural anatomy, come in more sizes and are made from longer-lasting materials. While surgery is still a big decision, it no longer has to wait until later in life. For many, it can be a smart step toward staying active and independent.
“New research and innovations have led to better outcomes for the million-plus people who have joint replacement surgery each year,” says Daniel Sun, MD, orthopedic surgeon at Tufts Medical Center. “This is not your grandma’s hip replacement.”
Advances in anesthesia and surgery
One of the most challenging parts of joint replacement used to be the invasive surgery itself — the risks and discomfort often outweighed the pain caused by the original joint damage. But key developments have made the procedure simpler and safer, almost routine for specialists.
First, pain management has improved dramatically. Preemptive medications and increased use of spinal anesthesia allow patients to mobilize sooner after surgery, reducing pain and lowering the risk of complications.
“During a spinal, a thin needle is inserted just outside the spinal cord, similar to an epidural,” explains Dr. Sun. “Neuraxial anesthesia provides pain relief during and after surgery without side effects like nausea or grogginess, which can come with general anesthesia. The choice of anesthesia depends on your medical history and pre-existing conditions.”
In addition to better pain control, robot-assisted surgery provides surgeons with a precise roadmap for the procedure. These systems map the joint ahead of time to help plan implant size and define boundaries for surgical tools, improving accuracy.
“The robot assists with planning patient anatomy, sizing the implant, and creating safe zones for surgical instruments,” says Dr. Sun. “It’s available to any patient, but especially useful for more complex cases.”
Robot-assisted surgery also enables more precise bone cuts, reducing tissue damage, blood loss and scarring.
Shorter recovery times
Minimally invasive surgery techniques have revolutionized hip replacement. This approach reduces the time it takes for patients to recover and get back to their lives with a new joint.
“Most hip and knee replacement patients are walking within hours after surgery,” says Dr. Sun. “At Tufts Medicine, nurses and physical therapists work closely with patients to ensure mobility.”
Shorter recovery means fewer hospital days and a quicker return to daily activities.
In the past, joint replacement patients might spend several days in the hospital. While it remains major surgery, many patients can now leave within 24 hours.

More durable replacement joints
Another common concern has been how long joint replacements last. Older materials and designs typically lasted 10 to 20 years, making repeat surgery likely, especially for younger patients.
Today’s implants use stronger materials like wear-resistant plastics and bone-integrating metals, giving replacements a much longer lifespan and making surgery an option for younger adults.
“Today, the plastic insert is usually the limiting factor for an implant’s longevity,” says Dr. Sun. “These materials have been used for about 30 years and continue to perform well, so we can reasonably expect replacements to last 30 or more years, barring complications.”
Improved biomechanical design and better customization to a patient’s body also enhance function and durability.
The bottom line
Developments in anesthesia, surgical precision, recovery protocols and implant technology have made joint replacement safer, less painful and a viable option for more patients at different stages of life. We no longer have to simply live with joint pain — modern joint replacement can help restore mobility and quality of life.
