Patients younger than 65 years had greater pain relief after unicompartmental knee arthroplasty, according to results.
Researchers had 104 patients who underwent unicompartmental knee arthroplasty (UKA) complete the WOMAC questionnaire preoperatively and at a minimum of 2 years postoperatively. Researchers evaluated age, BMI, gender, preoperative radiographic severity of the various knee compartments, and preoperative and postoperative mechanical axis alignments.
At an average of 2.3-years follow-up, results showed WOMAC results were not influenced by BMI, gender and preoperative severity among the various knee compartments. Compared with patients aged 65 years and older, researchers found inferior preoperative WOMAC stiffness, pain and total scores among patients younger than 65 years. According to results, both age groups had significant differences on the postoperative WOMAC stiffness subscale, in favor of patients 65 years and older. Researchers noted significantly superior WOMAC pain, function and total scores correlated with a postoperative varus mechanical axis alignment of 1° to 4° vs. a varus of 1° or less or 4° or greater. – by Casey Tingle
