Life After Knee Replacement
Post-operative Care
In a small percentage of people, as with all major surgical procedures, knee
replacement complications can occur. Below is a list of potential knee
replacement complications and steps you can take to prevent their occurrence.
Thrombophlebitis
Thiscondition is also known as deep vein thrombosis (DVT), and it occurs when
the large veins of the leg form blood clots and, in some instances, become
lodged in the capillaries of the lung and cause a pulmonary embolism. The
following steps may be taken to avoid knee replacement complications due to
blood clots:
- Blood-thinning medication (anticoagulants)
- Elastic stockings (TED hose)
- Foot and ankle exercises to increase blood flow and enhance venous return in
the lower leg.
IMPORTANT: If you develop swelling, redness, pain and/or tenderness in
the calf muscle, report these symptoms to your orthopaedic surgeon or internist
immediately.
Infection
Although great precaution is taken before, during, and after surgery,
infections do occur in a small percentage of patients following knee
replacement surgery. Steps you can take to minimize this knee replacement
complication include the following:
- Monitor your incision closely and immediately report any redness, swelling,
tenderness, increased drainage, foul odor, persistent fever above 100.4 degrees
orally, and increasing pain.
- Take your antibiotics as directed and complete the recommended dosage
duration.
- Strictly follow the incision care guidelines your surgeon recommends.
Pneumonia
Because your lungs tend to become “lazy” as a result of the anesthesia,
secretions may pool at the base of your lungs, which may lead to lung
congestion or pneumonia. The following steps may be taken to minimize this
complication:
- Deep breathing exercises: A simple analogy to illustrate proper deep
breathing is to, “smell the roses and blow out the candles.” In other words,
inhale through your nose, and exhale through your mouth at a slow and
controlled rate.
- Incentive Spirometer: This simple device gives you visual feedback while you
perform your deep breathing exercises. Your nurse or respiratory therapist will
demonstrate proper technique.
Knee Stiffness
In some cases, the mobility of your knee following surgery may be significantly
restricted and you may develop a contracture in the joint that will cause
stiffness during walking or other activities of daily living. The following
steps must be taken to maximize your range of motion following surgery:
- Strict adherence to the CPM protocol as prescribed by your surgeon
- Early physical therapy (Day 1 or 2) to begin range of motion exercises and
walking program
- Edema control to reduce swelling (ice, compression stocking, and elevation)
- Adequate pain control so you can tolerate the rehabilitation regime
