After knee replacement surgery, it is common for people to wake up several times during the night, sometimes for several months. Many patients find that sleeping in a recliner early on is more comfortable than sleeping in bed. Not sleeping through the night is the most common complaint at the 6 week follow-up appointment. The knee is usually sore after the day’s activity and it can be very achy at night. It is important to decrease your activity in the few hours before bed and to ice the knee. Taking pain medication, especially an anti-inflammatory, and/or over-the-counter treatments such as melatonin before bed can be very helpful. Unfortunately, a specific treatment regimen that is effective for most people has not yet been identified.

Ideally, significant travel should wait until 4 weeks after surgery. When you are traveling, wear your compression socks. If you are flying, get up and walk up and down the aisle several times during the flight. If you are driving, stop every 90-120 minutes to stretch your legs and walk.
-
A stool softener will be prescribed with your postoperative medications. If you would prefer something else, you may take over-the-counter Miralax or prune juice.
-
Most patients can start chipping and putting around 6 weeks after surgery. You may gradually increase your swing and club size as you are comfortable. Your physical therapist will help guide you with your return to activities.

It is likely that the replacement will be identified during airport security screening. We no longer provide implant cards to patients as joint replacements and other orthopaedic devices are commonplace. The joint replacement should not cause any significant delay making your way through airport security.
-
You should inform your dental office and all of your treating physicians that you have a joint replacement. Dental procedures (including routine cleaning) and other invasive procedures (such as urological, gastrointestinal, or gynecological procedures) can result in bacteria entering your bloodstream. Although it is a very low risk, it may be possible that bacteria could infect your joint replacement. To help prevent infections of your replacement, it is recommended that you take an antibiotic prior to dental visits or any other procedure. Please call the office to have an antibiotic prescribed prior to these appointments.
Frequently Asked Questions for Knees
-
All patients develop swelling of the knee for a period of time after knee replacement. The swelling can take a long time to go down, and many people end up with a knee that is slightly larger than the original knee. It is rare for the knee to need to be drained for the expected postoperative swelling. Icing the knee several times daily and limiting excessive walking during the first two weeks after surgery will help minimize the swelling. The front of the knee is expected to be warm; this is a normal part of the healing process. The knee can stay warm for up to one year after surgery.
-
Kneeling is permitted six months after surgery. After healing is complete, approximately one-third of patients have an odd or unpleasant sensation while kneeling. This feeling can be made more tolerable by conditioning the knee over the course of 5-6 weeks. For one week at a time, kneel on progressively firmer objects for 10 minutes each day (for example: the couch, then a couch cushion on the floor, then a pillow, then a rug, and then the bare floor).
-
The nerves that control the sensation of the skin on the outside of the knee cross over the front of the knee. Those nerves are unavoidably cut by the incision. Every patient has numbness on the outside of the knee after surgery. This area of numbness usually grows smaller over time and sometimes resolves, but it is not uncommon to have a small patch of skin that is persistently numb.
Frequently Asked Questions for Hips
-
The operative leg commonly feels longer for a period of time after the surgery. As the hip becomes more arthritic and the cartilage wears away, the leg tends to becomes shorter over time. The hip replacement attempts to restore the leg to its original position as closely as possible. It is important to have appropriate muscle tension around the hip so the mechanics and the stability of the hip are optimized, and sometimes the leg is slightly lengthened in order to optimize stability. Lengthening of up to 1 cm in comparison to the non-operative hip is usually well-tolerated. The weakness around the hip after surgery also contributes to the feeling of the operative leg being longer. This feeling gradually improves over the course of several months. It is recommended to avoid using a shoe lift for the first three months after the surgery.
-
Sleeping on your side is permitted after surgery, but it is preferable to wait until the incision has healed. Patients sometimes feel more comfortable sleeping with a pillow between their legs, but it is not required.
