Objectives: To determine if intra-articular (ia) anti-tumour necrosis factor (TNF) yielded benefit in patients failing ia steroid injections and determine the safety and durability of single and repeated ia anti-TNF treatment in inflammatory arthritis. Methods: Patients with inflammatory arthritis having one or two active joints, and having failed previous ia steroids were injected with ia adalimumab or ia etanercept mixed with triamcinolone and lidocaine via a retrospective chart audit.

Twenty-five knees, 17 ankles, 1 wrist and 1 PIP were injected of whom 6 had repeated injections to a joint. Nine were on concomitant systemic anti-TNF therapy. Fifteen had RA, 4 had a seronegativearthropathy, 3 had psoriatic arthritis, and 4 had other arthritis. When determining a response to ia anti-TNF for > 2 months in patients with sufficient follow up 13 of 18 receiving iaadalimumab and 6/7 with ia etanercept had benefit. There were no serious adverse events (SAEs) and only one AE in a wrist post ia adalimumab, with rebound inflammation after 6 weeks of marked relief. Two were able to cancel or postpone joint surgery(knee and ankle)and one cancelled an yttrium injection. Conclusions: There were no SAEs and prolonged benefit was found with ia anti-TNF and steroids and lidocaine compared to previous ia steroids with lidocaine in the majority (20/27). Although not approved for ia administration, ia anti-TNFs may be cost effective in persistent synovitis of one or two joints recalcitrant to ia steroids.
