Knee Replacement Soon? Hit the Pause Button...

So many patients with knee osteoarthritis ask me the question “well, if I’m eventually going to require knee replacement, shouldn’t I go ahead and have it done now?”

Well, there’s not just one answer to that question, but here are some of my replies:

-Most knee replacements only last 15 to 25 years. After that, the implants start to loosen, creating pain, swelling or a sense of instability.

-Most patients are at higher risk for surgical complications at the time of a second surgery, known as a “revision,” simply due to their age and likelihood of having more significant medical conditions.

-Surgical techniques are improving with breakthroughs every two or three years. Robotically-assisted replacements and having replacements as an outpatient surgery are two recent examples. More advancements are sure to come.

-One should never base the need to have knee replacement on the appearance of the x-rays. Some patients with “bone-on-bone” arthritis have minimal pain and excellent function. These patients don’t need a replacement.

-What often produces the most pain is an unhealthy environment within the knee joint, some of which may be controlled with injections like platelet-rich plasma (PRP).

-We also believe that PRP may put a stop sign or at least a yellow light on cartilage deterioration. We do not make guarantees about cartilage regrowth, but if we can stabilize a patient’s current cartilage and slow or stop the deterioration, then we are slowing the process of osteoarthritis and perhaps delaying the need for knee replacement.

-For a joint condition like arthritis, we often think of PRP as a maintenance treatment, not just a one-time application. Much like the maintenance for your car, you don’t just take it to the mechanic once or twice and then get a new car. This is an ongoing process.

-Assuming a patient is in that 80% success group with PRP treatments, one should plan on likely having repeat PRP injections every 1 to 2 years. This is a great long-term investment in the health of your knee.

In summary, for some individuals, knee replacement is inevitable, but there can be great value in delaying this surgery to increase the odds that it is required just once in a patient’s lifetime. For others, treatments like PRP can eliminate the need to have a replacement.
