Table 2.
Clinical and radiological results after implantation of 128 low-contact-stress (LCS) total knee arthroplasties (TKA) in 126 patients (90 women and 34 men) in a consecutive series at minimum follow-up of 5 years. We observed no significant differences in clinical scores between female and male patients with respect to range of motion (ROM), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Knee Society Score (KSS) (pain or functional score) and patterns of radiolucent lines
