How Safe Is a Total Knee Replacement? Atlanta, GA
Physical injury of leg / knee / joint at home.

If chronic knee pain has made it difficult to walk, climb stairs, or enjoy your favorite activities, you’re not alone. More than 790,000 Americans undergo total knee replacement (TKR) surgery each year, according to the Agency for Healthcare Research and Quality (AHRQ). For most, this procedure dramatically reduces pain, restores mobility, and improves quality of life.

At Ortho Sport & Spine Physicians, with dozens of locations across the U.S., our board-certified orthopedic surgeons specialize in advanced joint replacement procedures, including robotic-assisted total knee replacement. Patients often ask: “Is total knee replacement safe?” The short answer is yes — when performed by experienced specialists using modern techniques, this procedure is one of the safest and most successful surgeries in orthopedics.

The Effectiveness of Total Knee Replacement

Total knee replacement (also known as total knee arthroplasty) involves removing the damaged surfaces of the knee joint — typically due to arthritis or injury — and replacing them with durable, biocompatible implants. These implants mimic the movement of a healthy knee, allowing smoother motion and significant pain relief.

According to the American Academy of Orthopaedic Surgeons (AAOS):

  • Over 90% of knee replacements remain functional and pain-free 15 to 20 years after surgery.
  • More than 85% of patients report substantial pain reduction and improved ability to perform daily activities.
  • Most patients regain 90–120 degrees of motion, enough for walking, sitting, and light recreational activities.

For individuals who have suffered years of knee pain from osteoarthritis, rheumatoid arthritis, post-traumatic injuries, or cartilage degeneration, knee replacement can restore independence and long-term mobility.

Is Total Knee Replacement Safe?

Yes — total knee replacement is considered a very safe and reliable procedure, especially when performed at a high-volume center like Ortho Sport & Spine Physicians. Advances in surgical techniques, anesthesia, and implant technology have significantly reduced risks.

Modern procedures often include:

  • Minimally invasive techniques that require smaller incisions and cause less tissue trauma
  • Computer navigation or robotic assistance for improved precision and alignment
  • Enhanced recovery protocols (ERAS) that reduce complications and speed healing

According to the Cleveland Clinic, the overall complication rate for total knee replacement is less than 2% in otherwise healthy patients. Infection, blood clots, and stiffness are rare, and preventive measures are taken before and after surgery to minimize these risks.

What to Expect Before and After Surgery

If you are considering total knee replacement, understanding the process can help you feel confident and prepared.

Before Surgery

Your orthopedic surgeon will perform a thorough evaluation, including X-rays or MRI imaging, to confirm that replacement is the best option. You may also undergo lab tests and pre-surgical clearance to ensure optimal safety.

Patients are often encouraged to:

  • Maintain a healthy weight to reduce surgical risk
  • Strengthen leg muscles with gentle exercises
  • Stop smoking and manage chronic conditions like diabetes

During Surgery

The procedure typically lasts 2-3 hours. Damaged bone and cartilage are removed, and custom-fitted implants are placed with precision. Many procedures now use robotic-assisted technology, allowing for enhanced accuracy and better long-term results.

After Surgery

Most patients begin gentle movement within 24 hours of surgery. Physical therapy starts early to rebuild strength and range of motion. Hospital stays are shorter than ever — many patients return home within 1 to 2 days.

By 6 weeks, most individuals can resume low-impact activities like walking and light exercise. Full recovery typically occurs within 3 to 6 months, depending on overall health and rehabilitation effort.

Longevity and Quality of Life After Knee Replacement

Modern knee implants are designed to last 20 years or longer. For younger, more active patients, newer materials such as highly cross-linked polyethylene and oxidation-resistant metal alloys increase durability and reduce wear.

Long-term studies show that:

  • Over 90% of patients report satisfaction with their knee replacement results.
  • The average pain score improvement is between 75–90% after recovery.
  • The majority of patients can resume normal activities, including swimming, golfing, and cycling.

When compared to the limitations caused by severe arthritis or chronic pain, total knee replacement is an overwhelmingly safe and life-changing option.

Surgery was a success my left knee is fully functional again. Langer and his staff was very helpful through this entire process they assigned me a top physical therapist Cara which was great at helping me to improve now just up to me to continue to condition myself back to the way I was physically before the injury and hopefully I never have to endure any future injuries that lead to surgery. Overall a great help and experience after surgery was completed. Thank You to Langer and his staff.

Ortho Sport & Spine Physicians are excellent in the work they do. They take their time with each patient and make sure you walk away with an understanding of exactly what you're going through. I have been a patient here twice and I could 100% assure you that you will have a great experience. Further the physicians are very knowledgeable and experienced at what they do. Moreover, the entire staff are welcoming and accommodating to your needs. I work in Entertainment, and have appeared several times on television (Google "David Wells and Ricky Johnson). I recommend and trust Ortho Sport & Spine Physicians.
