Knee Replacement


Knee Replacement Sugery Options

Total Knee Replacement ►
In a total knee replacement, damaged tissue is removed and the knee joint is resurfaced using artificial materials. The surgery is an option for patients who suffer from advanced arthritis of the knee or joint problems that limit basic activities and have not responded to other treatment.

Partial (Unicompartmental) Knee Replacement ►
In partial knee replacement, the surgeon removes only the damaged portion of the knee, leaving the healthy parts untouched. Only one compartment is replaced, compared with three compartments in a full joint replacement. About 20 to 25 percent of those who need knee replacement are candidates for a partial knee replacement.

Rotating Platform Knee Replacement ►
Rotating platform knees are designed to accommodate more normal movement of the knee and allows the knee to slightly rotate while it flexes and extends, accommodating your body's normal need for rotation. They provide more fluid movement and minimal wear, allowing implants to last longer.

Knee Replacement Recovery

After surgery, you will begin a physical therapy routine designed to help you regain your strength, balance, and mobility. Most patients return directly home after surgery, while some go to a rehabilitation hospital for more physical therapy. As with other joint surgeries, patients must do hourly exercises to strengthen the joint and regain mobility. Patients strive to walk with a cane, or unassisted, within six weeks of surgery. Initial recovery takes about six to eight weeks, and then often continues for a full year.

Knee Revision

Knee replacements may last your entire life. In some cases, however, people develop problems with their knee replacements. These problems can stem from various factors, including normal wear and tear, a fracture, an infection, or unexplained pain or stiffness. Knee revision surgery corrects these problems by replacing the damaged knee implant with a healthy new one.

Gender-Specific Joint Replacement

Studies have shown that the shape of women's knees differs from men's. And it's not just a size difference. Although traditional replacement knees are available in different sizes, the gender knee reproduces the unique female shape. MedStar uses the first and only implant shaped to fit a woman's anatomy. The design is based on pioneering research that confirmed the differences between the male and female knee joints. The outcome is a more comfortable, custom-fitting implant offering optimal range of motion.

Infected Total Joints

If a total joint replacement becomes infected, the health of the joint and limb, as well as the overall health of the patient, become an immediate concern. Not all orthopedic specialists are trained to manage and treat infected total joints. At MedStar St. Mary's Hospital, our orthopedic surgeons appropriately manage and aggressively treat infections. This often times requires removal of the total joint implant and a course of antibiotics followed by revision joint replacement. While this is unfortunate, it is critical for removing the bacteria from your system and maximizing your overall health and outcome.

5 Things to Know about Knee Replacements 

  1. It typically takes three to six months to regain strength and range of motion following surgery.
  2. Patients can expect soreness after surgery, but many report significant pain relief
  3. Post-operative rehabilitation is important to successful recovery.
  4. Knee replacements can last up to 25 years, but some wear out sooner. One successful surgery is the goal, which is why non surgical measures are exhausted before surgery is recommended.
  5. Level of activity, age, surgical technique, and implant choice contribute to the longevity of a knee replacement.
