Caring For Your New Knee Implant

During your first few weeks at home, it is important that you move properly. You should avoid crossing your legs while sitting or standing, and do not allow your knees to come higher than your hips. Also, avoid sitting in low sofas or chairs.

It is important to have some assistance when going up and down stairs. When climbing stairs, always use the railing and lead with your non-surgical leg, one step at a time. When going down stairs hold onto the railing and lead with your surgical leg, one step at a time.

Continue the prescribed exercises during your entire recovery period, and talk to your doctor about developing an exercise program after you fully recover. Golfing, swimming, walking, and bicycling are excellent sources of low-impact exercise if your surgeon feels that these activities are appropriate for your individual condition.

Follow your surgeon’s check-up plan. It is common to visit with your surgeon at three, six, and nine months after surgery and annually thereafter.

Caregivers Guide

As a caregiver, your role is important for helping your friend or loved one recover from joint replacement surgery. When at home, there are a variety of things you need to know for the patient's safety, recovery, and comfort. This information will help you with some of the many questions and concerns as you prepare to care for your joint replacement patient.

Home Safety and Avoiding Falls

  • Pick up throw rugs and tack down loose carpeting. Cover slippery surfaces with carpets that are firmly anchored to the floor or that have non-skid backs
  • Place regularly used items such as remote controls, medications, and reading materials, in easy-to-reach locations
  • Widen furniture paths to accommodate a walker or cane
  • Place frequently used cooking supplies and utensils where they can be reached without too much bending or stretching
  • Be aware of all floor hazards such as pets, small objects, or uneven surfaces
  • Provide good lighting throughout. Install nightlights in the bathrooms, bedrooms, and hallways
  • Keep extension cords and telephone cords out of pathways. Do NOT run wires under rugs, this is a fire hazard
  • Do not let the patient lift heavy objects for the first three months and then only with your surgeons permission
  • Un-tuck bedding to allow for easier access into and out of the patients bed

Body Changes

  • The patient's appetite may be poor. Make sure they drink plenty of fluids to keep them from getting dehydrated. Their desire for solid food should return
  • Joint replacement patients may have difficulty sleeping, which is normal. Do not let the patient sleep or nap too much during the day
  • The patient's energy level will be decreased for the first month
  • Pain medications that contain narcotics promote constipation. Follow the surgeon's recommendations for using stool softeners or laxatives such as milk of magnesia if necessary

Blood Thinners

Blood thinners may be given to help avoid blood clots in the patient's legs. Always follow the surgeon's recommendations regarding blood thinners.


  • The patient may be asked to wear special stockings. These stockings are used to help compress the veins in their legs. This helps to keep swelling down and reduces the chance for blood clots
  • If swelling in the operative leg is bothersome, help the patient elevate the leg for short periods throughout the day. It is best when the patient lies down and raises the leg above heart level
  • Make sure the patient wears the stockings continuously, removing for one to two hours twice a day
  • Notify the physician if the patient notices increased pain or swelling in either leg

Incision Care

  • Keep the incision dry
  • Keep the incision covered with a light dry dressing until the staples are removed, usually 10-14 days
  • Patient should request showering/bathing instructions from surgeon
  • Notify the surgeon if there is increased drainage, redness, pain, odor, or heat around the incision
  • Take the patient’s temperature if he or she feels warm or sick. Call the surgeon if it exceeds 100.5ºF

Changing the Dressing (ONLY IF DIRECTED BY SURGEON)

  • Wash hands
  • Open all dressing materials (ABD pads, 4x4 if needed, Betadine® swab if indicated)
  • Remove stocking and old dressing
  • Inspect incision for the following:
    • Increased redness
    • Increase in clear drainage
    • Yellow/green drainage
    • Odor
    • Surrounding skin is hot to touch
  • If Betadine® is ordered, take one Betadine® swab and paint the incision from top to bottom. Then turn the swab over and paint the incision from bottom to top. Use remaining swab to paint the drain site
  • Pick up ABD pad by one corner and lay over incision. Be careful not to touch the inside of the dressing that will lie over the incision
  • Place one ABD pad lengthwise and place the other ABD crosswise to form a "T" (to cover drain site)
  • Tape dressing in place

Controlling Discomfort

  • Pain medicine should be taken at least 30 minutes before physical therapy
  • Encourage patient to gradually wean him or herself from prescription pain medication. Follow the surgeon's recommendations for taking over-the-counter medication in place of prescription pain medication
  • Have patient change position every 45 minutes throughout the day
  • Use ice for pain control. Applying ice to the affected joint will decrease discomfort, but do not use for more than 20 minutes at a time each hour. Use ice before and after the patient exercises according to their prescribed program. A bag of frozen peas wrapped in a kitchen towel makes an ideal ice pack. Mark the bag of peas and return them to the freezer (to be used as an ice pack later)

Recognizing & Preventing Potential Complications

Signs of Infection

  • Increased swelling and redness at incision site
  • Change in color, odor of drainage
  • Increased pain in surgical joint
  • Fever greater than 100.5º F

Blood Clots in Legs

Surgery may cause the blood to slow and coagulate in the veins of the patient's legs, creating a blood clot. This is why patients take blood thinners after surgery. If a clot occurs despite these measures, the patient may need to be admitted to the hospital to receive intravenous blood thinners. Prompt treatment usually prevents the more serious complication of pulmonary embolus.

Signs of blood clots in leg

  • Swelling in thigh, calf or ankle that does not go down with elevation.
  • Pain, heat and tenderness in calf, back of knee or groin area. NOTE: Blood clots can form in either leg.

Prevention of blood clots

  • Foot and ankle pumps
  • Walking
  • Compression stockings
  • Blood thinners such as Coumadin® or Heparin 

Pulmonary Embolus

This is an emergency, if suspected CALL 911 immediately

An unrecognized blood clot could break away from the vein and travel to the lungs.

Signs of a pulmonary embolus

  • Sudden chest pain
  • Difficult and/or rapid breathing
  • Shortness of breath
  • Sweating
  • Confusion

Prevention of pulmonary embolus

  • Heparin or warfarin therapy. Taking Anticoagulants such as heparin and warfarin decreases your chances of pulmonary embolus
  • Graduated compression stockings. Compression stockings offer a safe, simple and inexpensive way to keep blood from stagnating after general surgery.  They steadily squeeze your legs, helping to increase your blood flow efficiency as long as the stockings are not overly tightened
  • Pneumatic compression. Pneumatic compression can dramatically reduce the risk of blood clots, especially in people who have had joint replacement surgery
  • Physical activity. Becoming active as soon after surgery as possible can help prevent pulmonary embolism and speed up recovery process
