6 Things to Know about Your Knee Replacement

6 Things to Know about Your Knee Replacement

by Athletico4 Comments

Perhaps you are the individual who seeks out a physical therapist because they have a great deal of trepidation and the strong desire to avoid surgery after receiving a diagnosis of knee osteoarthritis or “degeneration” from your physician. Or maybe you’re attending physical therapy pre or post-operatively empowered to regain pain-free living and full function. Whichever profile you identify with, this blog will provide you the knowledge to consider before a total knee replacement.

1. Knee replacement is common

According to the Agency for Healthcare Research and Quality on average, more than 790,000 knee replacements are performed annually in the United States.1 Furthermore, knee replacements are the most common joint replacement, and, as reported by the American Academy of Orthopedic Physicians, they are one of the most successful procedures in all of medicine.2 Additionally, since the advent of the procedure, replacement components, technique, and ability to mimic normal joint motion have improved, the length of surgery, hospital stay, and time to regain function have also decreased. Rates of same day surgery, which meet all of the above criteria, are also becoming more common. However, despite the commonality of the procedure, it is imperative to find a reputable surgeon who specializes in knee or joint replacement. It is also helpful to recognize the experiences related by friends or family after surgery may not be the same for you.

2. Recovery takes longer than expected

While the vast majority of patients achieve full pain-free functional recovery, the process can take longer than expected. This is easier to understand when you recognize both the length of time in which you may have been losing strength and mobility and the length of time required to regain these. From my observations, on average, most patients are able to walk shorter distances independently after 1-4 weeks, have few complaints or limitations after 3-4 months, and report the replacement is closer to “their knee” after 9 months to one year.

3. Pain is not immediately eliminated

While it may be intimidating to learn that a knee replacement can, at least initially, be a painful
process, patients report the pain is different. This means the pain from cartilage wearing and degenerating is eliminated and the pain is the result from the surgical procedure. However, surgeons work closely with patients to develop a pain management routine consisting of ice, medication, mobility, and reduction of swelling and joint loading to help minimize pain.

4. You can resume most activities but….

Be aware of returning too quickly or at a high level. Most surgeons discourage
high impact activities such as running and downhill skiing due to the accelerated wearing of the
prosthetic components. Returning too rapidly can lengthen recovery and result in a regression
in rehabilitation. Even walking longer at a store, prolonged standing, or limping can increase the load on your knee and result in increased pain, swelling, or limited function.

5. Avoid limping

The two primary reasons to avoid limping are to prevent increased loading on the recovering knee and to avoid development of an abnormal gait pattern. This may mean you will need to use a cane or walker for longer, however, adhering to this advice will ultimately improve your chance for a faster recovery by minimizing loading on the healing joint and subsequent swelling, pain, and delay in strength gains. Avoid your believed stigma of assistive devices (they are actually quite common today). Others may actually be more concerned if they see you limping. And yes, this includes grabbing onto counters and walls for stability which is unsafe and
therefore discouraged.

6. Don’t wait until function is severely compromised

It is rarely a requirement to have knee replacement surgery, and in fact, is also rarely
recommended when radiographs reveal degeneration, yet an individual has only minor or no
symptoms. Yet, waiting until you are no longer able to walk effectively, have significantly lost
mobility or strength, or secondary to fear, is not worthwhile as the rate of recovery and potential
for return to full function can be detrimentally reduced. And, according to post-operative
patients, it is not worthwhile to continue functioning at a lower than desired level or with
significant pain for the traded ability to regain a greater independence and, resulting return to
pain-free enjoyment of activities.

The list below, from the American Academy of Orthopedic Surgeons website is a helpful reference for when to have surgery for individuals pondering knee replacement.2 Surgery may be advisable when you have one or more of the following criteria:

Severe knee pain or stiffness that limits everyday activities, including walking, climbing
stairs, and getting in and out of chairs. It may be hard to walk more than a few blocks
without significant pain and it may be necessary to use a cane or walker

  • Moderate or severe knee pain while resting, either day or night
  • Chronic knee inflammation and swelling that does not improve with rest or medications
  • Knee deformity — a bowing in or out of the knee
  • Failure to substantially improve with conservative treatments such as anti-inflammatory medications, cortisone or lubricating injections, physical therapy, or arthroscopic surgery
