Defining Joint Replacement Acronyms Used by Your Surgeon


In a world of LOL & OMG, sometimes physicians use abbreviations and acronyms for their medical terminology. This can be confusing if you do not know the lingo.

If you have consulted with an orthopedic surgeon in Arkansas for joint treatment pain, there are a few key acronyms to understand. This information can help you understand what kind of treatment your doctor is recommending.

Total Knee Replacement (TKR)/Total Knee Arthroplasty (TKA)

Although TKR and TKA are both widely used, it’s important to note that both represent the same procedure. No matter which acronym is used, it still involves removing and resurfacing all of the damaged bone and cartilage within the joint. Any healthy bone material is left in place to help support the new, artificial components to the joint.

Partial Knee Replacement (PKR)/Unicompartmental Knee Arthroplasty (UKA)

Like the total knee replacement procedure, both PKR and UKA refer to the same procedure. With a partial knee replacement, one or more components of the joint are completely replaced. Unlike the total replacement procedure, all healthy material is left in place, not just bone. Although a partial replacement occurs less frequently than total replacement, occurring less than 10 percent of the time, it’s still an acronym you might hear mentioned by your surgeon.

Total Hip Replacement (THR)

A total hip replacement is the most common form of the hip replacement procedures. It involves an incision through the upper thigh while the patient lies on their side. The procedure typically calls for an incision roughly 10 inches in length but can be as short as 4 inches depending on the patient and circumstances.

Direct Anterior Hip Replacement (DAA)

A DAA procedure is the newer of the hip replacement procedures and involves the patient lying on a specialized table. The is placed on the upper front of the thigh. The DAA requires a smaller incision and less cut muscle and tissue than the THR and therefore typically requires a shorter recovery period. However, the DAA is not recommended for all patients and isn’t performed by all surgeons.

Bilateral Hip & Knee Replacement (BTHR, BTKR), Double Hip Replacement & Double Knee Replacement

Although the terms “bilateral” and “double” might seem like more complicated procedures, in actuality it simply means both knee or hip joints are being replaced at the same time. In other words, the same procedures described in the TKR, PKR, THR and DAA sections are performed during the same surgical experience.
