Replacing both hips or both knees in a single surgery is technically possible. It’s called simultaneous bilateral joint replacement. Many surgeons still recommend splitting the two sides into staged procedures, done weeks or months apart, because spacing the surgeries out tends to lower the overall health risk. Which approach fits a given patient comes down to age, fitness, and how well the body is likely to handle the combined demands of surgery and recovery.
According to Dr. Avinashdev Upadhyay, an orthopedic surgeon in Navi Mumbai, “Simultaneous surgery isn’t automatically the better option just because it saves time. The real question is whether a patient’s heart, lungs, and overall fitness can handle both joints healing at once.”
Dr. Upadhyay’s Clinical Tip
“When both knees need replacement, I typically address the more functionally limiting one first. Starting there makes rehabilitation more manageable and gives the patient a stronger base to work from during the second procedure.”
Wondering if bilateral surgery is right for you?
Who Is Suitable for Bilateral Joint Replacement?
Suitability comes down to more than just having two damaged joints. Most patients are surprised how much the decision actually hinges on general health, not the joints themselves.
Age: Younger, otherwise healthy patients tend to tolerate simultaneous surgery better than older patients. Their bodies simply recover faster from combined surgical stress.
Fitness: Cardiovascular and respiratory fitness matter more here than for a single joint procedure. Because both systems need to support healing on two fronts at once.
Suitability: Candidates typically have similarly advanced damage in both joints, no major heart or lung conditions, and a stable overall health profile going into surgery.
Risks: Blood loss. Anesthesia duration. Infection risk. All three increase with simultaneous surgery compared to operating on one joint at a time.
A thorough pre-surgical evaluation is what actually determines candidacy here, not patient preference alone. Explore robotic knee replacement with Dr. Upadhyay to understand how precision planning supports this decision.
Staged vs Simultaneous: Which Approach Makes Sense?
Both paths lead to the same destination, just along different timelines.
Simultaneous Surgery: Both joints get replaced in a single operation. One hospital stay, one overall recovery period, but the physical demand on the body during that window is considerably higher.
Staged Surgery: The two procedures are spread weeks or months apart. This lowers the risk tied to any single surgery but stretches the total recovery timeline across two separate periods.
Recovery Comparison: Simultaneous replacement patients face a harder initial recovery with both legs recovering at the same time. Staged replacement patients have the other leg to lean on during each individual recovery, which matters more than people expect.
Making the Decision: Surgeons weigh age, fitness, joint symmetry, and patient preference together. So no single factor decides it alone.
The technique used for each joint matters just as much as the surgery schedule itself. Read more on robotic vs traditional hip replacement to see how that choice shapes recovery.
Why Choose Dr. Avinashdev Upadhyay for Bilateral Joint Replacement?
Dr. Avinashdev Upadhyay has performed 500+ joint replacements, including both staged and simultaneous bilateral procedures. He holds a Fellowship in Robotic Hip & Knee Joint Replacement from Australia. That training shapes how he plans each case, whether it’s one joint or two at once. Every patient gets evaluated individually rather than run through a one size fits all protocol.
That evaluation includes a realistic conversation about risk, recovery time, and what actually fits a patient’s daily life. Not just what’s technically possible. This individualized approach is what helps patients choose the path that suits their body, not just their calendar. Call +91 93260 59062 to discuss your options.

Frequently asked questions
1. Is it safe to replace both hips or knees at once?
For the right patient, yes. Good cardiovascular fitness and roughly equal damage in both joints matter more than age alone. But it does carry more risk than operating on a single joint, so not everyone qualifies.
2. What is the difference between staged and simultaneous surgery?
Simultaneous means both joints get done in one operation and one recovery period. Staged spreads the two procedures weeks or months apart. Slower overall, but each individual surgery carries less risk.
3. Who is not a good candidate for bilateral surgery?
Older patients. Anyone with heart or lung conditions. Patients whose joint damage isn’t roughly equal on both sides. Staged surgery tends to suit these cases better.
4. Does recovery take longer with bilateral surgery?
Not necessarily in total. But the first stretch after simultaneous surgery is harder, since both joints are healing at the same time and neither leg can carry the other.
