An asterisk (*) denotes values that are significantly different from the control group.

A caret symbol (^) denotes values that are significantly different between females and males.

PRO = patient-reported outcome; KOOS Sym = KOOS symptoms subscale; KOOS Sport = KOOS sport and recreation function subscale; KOOS QOL = KOOS knee-related quality of life subscale; and KOOS ADL = KOOS activities of daily living subscale. The KOOS-symptoms, Tegner, and Satisfaction outcomes had one additional female subject in the high-tension group, resulting in an overall sample size of 28 for that group. These differences in sample size are not indicated in the table.
