Consecutive patients undergoing knee arthroplasty completed questionnaires: FJS, Knee Injury and Osteoarthritis Outcome Score (KOOS) and WOMAC Score (mean 39 months after surgery), and were mailed a repeat questionnaire after 4 to 6 weeks. The test-retest reliability was almost perfect for the FJS (ICC = 0.97), and the FJS subdomains (ICC > 0.8). ⋯ The FJS demonstrates high test-retest reliability and construct validity compared to the Normalised WOMAC and KOOS Subscales. The FJS does not demonstrate the ceiling effect of the WOMAC or KOOS pain scores so may have greater discriminatory ability following TKR.

Intra-articular steroid injections are widely used for symptomatic relief of knee osteoarthritis. This study used a national database to determine if there is an association between preoperative intra-articular knee injection at various time intervals prior to ipsilateral TKA and infection. ⋯ There was no significant difference in patients who underwent TKA more than 3 months after injection. Ipsilateral knee injection within three months prior to TKA is associated with a significant increase in infection.
