Quick Answer
Arthroplasty is a surgical procedure in which a worn-out or damaged joint is replaced with a prosthesis to restore function and relieve pain. It may be a total or partial joint replacement, most commonly of the hips, knees and shoulders, for severe osteoarthritis or fractures. [1] It greatly improves quality of life but requires a recovery period with physical therapy. [1]
What the research says
Most hip replacements last decades, but not all. A systematic review and meta-analysis of studies with more than 15 years of follow-up found 25-year survival of 57.9% in national registries (215,676 hip replacements) and 77.6% in case series (13,212 hip replacements). The authors judged registry data less likely to be biased and concluded that a hip replacement can be expected to last 25 years in about 58% of patients (PubMed: Evans et al., Lancet, 2019 (hip)) [2].
About 82% of total knee replacements last 25 years. A companion systematic review and meta-analysis reported pooled registry 25-year survival of 82.3% for total knee replacements (14 registries) and 69.8% for partial (unicompartmental) knee replacements (PubMed: Evans et al., Lancet, 2019 (knee)) [3].
In a randomized trial, knee replacement relieved pain and improved function more than non-surgical care alone, but with more serious adverse events. Among 100 patients with moderate-to-severe knee osteoarthritis, knee replacement plus 12 weeks of non-surgical treatment improved the KOOS4 score by 32.5 points versus 16.0 points with non-surgical treatment alone (adjusted difference 15.8 points). Serious adverse events were more common with surgery (24 vs 6), and 26% of the non-surgical group had a knee replacement within 12 months (PubMed: Skou et al., N Engl J Med, 2015) [4].
What is arthroplasty (joint replacement)?
Arthroplasty is a specialized surgical intervention designed to restore the function of a joint that has been compromised by disease or injury. During the procedure, a surgeon removes the damaged surfaces of the natural joint and replaces them with an artificial prosthesis. [1] These prosthetic implants are engineered from durable materials such as metal alloys, high-grade plastics, or ceramics to mimic the movement and stability of a healthy joint. [1]
Healthcare providers categorize arthroplasty based on the extent of the replacement. A total joint replacement involves the complete removal and replacement of all joint components. [1] In contrast, a partial joint replacement, often referred to as joint resurfacing, targets only the specific areas of the joint that are damaged, preserving as much natural tissue as possible.
Common Joints Replaced
While any large joint can theoretically undergo arthroplasty, certain areas are more frequently targeted due to the high stress they endure during daily activities.
When is arthroplasty surgery needed?
Arthroplasty is typically considered a final option when nonsurgical management, such as physical therapy, medications, or activity modifications, no longer provides adequate relief. The primary driver for joint replacement is severe, chronic pain that interferes with daily living. Providers generally recommend surgery when severe symptoms do not improve after nonsurgical treatments have been tried. [1]
Common symptoms and conditions leading to arthroplasty include:
Severe Joint Pain: Persistent discomfort that limits sleep or basic movement.
Stiffness: Significant reduction in the joint's range of motion. [1]
Osteoarthritis: The most common cause, involving the wear and tear of protective cartilage. [1]
Traumatic Injury: Bone fractures or post-traumatic arthritis resulting from falls or accidents. [1]
Inflammatory Conditions: Rheumatoid arthritis that causes systemic joint damage. [1]

How is arthroplasty surgery performed?
Preparing for arthroplasty involves a comprehensive health evaluation, including physical exams, blood tests, and imaging such as X-rays, MRIs, or CT scans. [1] Patients are typically required to fast for eight hours prior to the operation and may need to adjust their current medications under medical supervision. [1]
During the surgery, which usually lasts a few hours, the patient receives either general or regional anesthesia. [1] The surgeon removes the damaged bone and cartilage, reshapes the remaining bone to fit the prosthesis, and secures the artificial components in place. [1] In some cases, robotic-assisted surgery is utilized, where a computer guides the surgical tools to enhance the precision of the implant placement. [1]
Post-Operative Monitoring
Immediately following the procedure, patients are monitored in a recovery room to ensure vital signs are stable and pain is managed. [1] While some patients may be discharged the same day, others require a hospital stay of several days depending on the joint replaced and their overall health status. [1]
What are recovery and rehabilitation like after arthroplasty?
Recovery from arthroplasty is a long-term process that takes at least a few months to complete. [1] The success of the surgery is heavily dependent on the patient's commitment to rehabilitation.
Phase | Typical Timeline | Primary Goals |
|---|---|---|
Immediate Post-Op | Days 1–7 | Pain management, preventing blood clots, initial mobility. |
Early Recovery | Weeks 2–6 | Increasing range of motion, wound healing, light activity. |
Strengthening | Months 2–4 | Building muscle support around the new joint, returning to daily tasks. |
Full Recovery | 6–12 Months | Returning to high-level activities, maximum joint stability. |

What are the risks and complications of arthroplasty?
Although arthroplasty is widely considered safe and effective, it is a major surgery with inherent risks. Potential complications include blood clots, infections at the surgical site, and nerve or blood vessel damage. [1] Over time, the prosthetic implant may also experience wear or loosening, which could necessitate a revision surgery. [1]

Conclusion
Arthroplasty is a transformative procedure for individuals suffering from debilitating joint conditions. By replacing damaged tissue with advanced prosthetic materials, the surgery offers a path back to an active, pain-free lifestyle. Patients considering this option should consult with an orthopedic specialist to discuss the specific benefits and risks tailored to their health history.
Next Steps for Joint Health
If you are experiencing persistent joint pain, consider the following actions:
Schedule a consultation with an orthopedic surgeon to evaluate your joint function.
Discuss nonsurgical options, such as physical therapy or injections, before committing to surgery.
Review your medical history, including conditions like diabetes or hemophilia, which may impact surgical outcomes. [1]

Osteoarthritis is the most frequent cause for joint replacement surgery.
2. How long does a joint replacement surgery take?
The procedure typically takes a few hours, depending on the joint being replaced.
3. What materials are used for prosthetic joints?
Prosthetic implants are usually made from metal, plastic, or ceramic materials.
4. Can I go home the same day after surgery?

Full recovery and maximum joint stability usually take between six months to a year.
6. What is robotic-assisted joint replacement?
Robotic-assisted joint replacement is a technique where a computer guides surgical tools for more accurate implant placement.
7. Is physical therapy necessary after arthroplasty?
Yes, physical therapy is critical for restoring mobility and ensuring the surgery's success.
