ABSTRACT
During the past 30 years, the unicompartmental knee arthroplasty has undergone growing pains with various implant designs, refining indications, and improving surgical techniques and instrumentation. Today, studies show survivorship results comparable to the tricompartmental total knee arthroplasty and a renewed interest has emerged. Even though the unicompartmental knee arthroplasty is recommended for only a select 10-15% who have osteoarthritis of the knee, it has many advantages over the total knee arthroplasty. Although the nursing care and rehabilitation are similar to the total knee arthroplasty, including wound care, prophylactic antibiotics, and venous thromboembolism prophylaxis, the patient frequently has less pain, increased range of motion, shorter hospitalization, and fewer complications, resulting in a quicker rehabilitation.
