Femoral lengthening might impair physical function and lead to structural changes in adjacent joints: 10 patients with 27 to 34 years’ follow-up

Background and purpose — Literature describing long-term functional outcome osteoarthritis (OA) in adjacent joints after femoral lengthening is rare. We evaluated physical function the presence of radiographic OA 10 patients ? 27 years lengthening.Patients methods conducted a cross-sectional study treated by unilateral lengthening. Follow-up was between 34 years. Physical 30-second sit-to-stand (30sSTS) stair test compared with reference values. 4 single-legged hop tests were used to assess difference lengthened contralateral limb.
