Rheumatoid arthritis (RA) is a frequent inflammatory arthritis that can lead to severe joint deformity and often requires orthopaedic surgical interventions. Anti-Tumor Necrosis Factor α (anti-TNFα) are biological disease-modifying antirheumatic drugs (DMARDs) increasingly used in the treatment of rheumatoid arthritis. An increased risk of opportunistic infection was demonstrated in patients treated with those drugs. This observation led many national committees to recommend anti-TNFα suspension in the perioperative period to avoid a raise in the postoperative infection risk in those patients. This approach is not supported by the data available in the current literature and it exposes patients to an increased risk of inflammatory flare ups of their disease during and after anti-TNFα suspension, which can compromise their postoperative rehabilitation and their quality of life.
The objective of this prospective randomized multicentric trial is to determine the effect of anti-TNFα suspension in the perioperative period on the postoperative infection risk. Overall, 660 rheumatoid arthritis patients requiring an elective foot or ankle surgery will be randomized into two groups. In the first group, anti-TNFα will be stopped 3 half-lives before the surgery while they will be continued in the second group. The postoperative infection rate will be compared between the two groups. Postoperative complication rates, flares and revision surgeries as well as the functional improvement will be compared.
The study hypothesis is that there is no significant difference in the risk of postoperative infection between the two groups.
Results from this study will help determine the optimal way to use anti-TNFα in the perioperative period and will therefore improve the quality of life of rheumatoid arthritis patients.

Active Comparator: Anti-TNF suspended perioperatively
Patients randomized to Group B will have their anti-TNFα therapy interrupted before surgery. Different authors suggested that anti-TNFα therapies should be suspended between two and five half-lives prior to surgery. In the current trial, anti-TNFα will be suspended three half-lives (± seven days) prior to surgery. All other medications used in the treatment of the disease (methotrexate, hydroxychloroquine, corticosteroid, etc.) will be documented and continued in the perioperative period. Non-steroidal anti-inflammatory drugs (NSAID) will be suspended seven days prior to surgery and will be restarted postoperatively. Anti-TNFα will be restarted once wound healing is completed.
Drug: Anti-TNF suspended perioperatively
Experimental: Anti-TNFα continued perioperatively
Patients randomized to Group A will continue their anti-TNFα treatment unaltered during the whole perioperative period. Surgery will be performed without consideration in regards to the timing of the treatment. The time elapsed between the last anti-TNFα administration and the surgery will nonetheless be documented.
Drug: Anti-TNFα continued perioperatively
- Surgical site infection [ Time Frame: Within one year after surgery ]Surgical site infection will be determined according to the definition of the Center for Disease Control (CDC).
- Disease flare up [ Time Frame: From the time the drug is suspended until one year after surgery ]
There is currently no widely accepted definition of RA disease flare up. In this study, patients satisfying one of the two following criteria will be considered as having a disease flare up:
I. Modification of the medication made necessary by an increase in the disease symptoms.
II. Increase in disease activity according to the Clinical Disease Activity Index (CDAI):
Increase from a remission or a low disease activity level at baseline to a moderate or high activity level.
Increase from a moderate disease activity level at baseline to a high activity level.
- An increase of 12 points or more on the CDAI in patients having a high disease activity level at baseline.
- Change in functional level [ Time Frame: Until one year after surgery ]The functional level of each patient is going to be assessed using the Health Assessment Questionnaire (HAQ) before and after the surgery in accordance with the follow-up schedule presented in the protocol.
- Poor wound healing [ Time Frame: Within one year of surgery or until wound is completely healed ]Complications associated with poor wound healing such as delayed wound healing and dehiscence will be noted. Delayed wound healing will be defined as a wound that isn't completely healed 14 days after surgery. Dehiscence will be defined as a wound that requires secondary closure or a wound that heals by secondary intention.
- Reoperation rate [ Time Frame: Within one year of surgery ]All reoperations made necessary following postoperative complications (ex : infection, implant retrieval, debridement) will be documented. More than one reoperation can be performed for the same patient. The reoperation rate expressed as a percentage will be compared between the two groups.
- Other adverse events [ Time Frame: Within one year of surgery ]All other significant adverse events will be documented. For example, systemic infection, septic choc, implant loosening and arthrodesis nonunion are going to be noted. Nonunion is going to be defined as the persistence of a joint space on more than 50% of the articular surface visible on CT-Scan six months after surgery associated with pain.
