What is a primary knee replacement?

Primary knee replacement, also known as total knee arthroplasty, is a surgical procedure whereby an injured or arthritic knee joint is replaced with an artificial implant. The intention of the surgery is to alleviate pain, enhance mobility, and restore function in patients with severe knee arthritis or injury.

Who is a good candidate for knee replacement surgery?

Candidates usually include any person with chronic knee pain, stiffness, or limited mobility that interferes with daily activities and conservative treatments such as physical therapy, medication, or lifestyle changes. Besides this, physicians will consider the patient’s general health, age, and activity level in determining whether surgery is indicated.

What are some of the risks associated with knee replacement surgery?

Though generally safe, possible risks of knee replacement include infection, blood clots, loosening of the implant, joint stiffness, and nerve or blood vessel damage in very extreme cases. Advances in surgical technique and post-operative care have tended to reduce these risks, but patients are closely monitored to handle complications.

How long will be the period of recovery after surgery on the knees?

The recovery time is unique to each individual, but most patients begin walking with support just a few days after surgery and continue their physical therapy program to gradually regain strength and flexibility. Most people return to light daily activities in 4 to 6 weeks while complete recovery may take 3 to 6 months. Optimum recovery is greatly improved when the rehabilitation program outlined by your physician is carefully followed.

How long do knee replacements last, and will I need another one in the future?

For implanted knees, it could last for 15 to 20 years or more, depending on particular weight, activity level, or type of implant. Though most patients will need only one knee replacement in a lifetime, some younger or more active ones may be faced with revision surgery if an implant is worn out.
