Knee arthritis is a chronic condition that’s characterized by the wear and tear of knee cartilage and soft tissue with age, overuse and/or injury. Once diagnosed, knee arthritis is typically treated using non-surgical treatment options, such as activity modification, anti-inflammatory medications and physical therapy. When knee arthritis doesn’t respond to nonsurgical treatment, surgical intervention may be necessary. Two surgical options used to treat knee arthritis are: (1) a total knee replacement and (2) a unicompartmental knee replacement.

 Total Knee Replacement

Total knee replacements (TKRs) are one of the most common orthopedic procedures. During a TKR, an orthopedic surgeon removes arthritic bone and cartilage and replaces it with metal and plastic components. After surgery, the patient has a new knee joint.

Unicompartmental Knee Replacement

An alternative surgical approach to treating knee arthritis is a unicompartmental knee replacement (UKR). The procedure is similar to a TKR in that arthritic bone is removed and replaced. However, it differs from a TKR in that it is only performed on one of the following knee compartments:

  • Medial (inside) compartment
  • Lateral (outside) compartment
  • Patellofemoral (front) compartment

After surgery, the patient has a knee joint that has been partially changed.

UKR Recovery and Results

When compared to patients who undergo a TKR, patients who undergo a UKR typically benefit in the following ways:

  • Less time is spent in the hospital after surgery
  • Symptom relief occurs sooner
  • The response to physical therapy is better

It is important to note that not all patients are candidates for a UKR.

Unicompartmental Knee Replacement Candidates

UKRs are limited to patients who have arthritis in only one knee compartment. In many cases, patients who are candidates for the procedure have arthritis that was caused by an accident or injury or arthritis that hasn’t reached severe stages.
