Total Ankle Arthroplasty for Rheumatoid Arthritis in Japanese Patients: A Retrospective Study of Intermediate to Long-Term Follow-up.

ABSTRACT: Background:Outcomes after total ankle arthroplasty (TAA) combined with additive techniques (augmentation of bone strength, control of soft-tissue balance, adjustment of the loading axis) for the treatment of rheumatoid arthritis were evaluated after intermediate to long-term follow-up. The influences of biologic treatment on the outcomes after TAA were also evaluated. Methods:We performed a retrospective observational study involving 50 ankles (44 patients) that underwent TAA for the treatment of rheumatoid arthritis. The mean duration of follow-up was 7.1 years. Clinical outcomes were evaluated with use of the Japanese Society for Surgery of the Foot (JSSF) scale score and a postoperative self-administered foot-evaluation questionnaire (SAFE-Q). Radiographic findings were evaluated as well. These parameters also were compared between patients managed with and without biologic treatment. Results:This procedure significantly improved the clinical scores of the JSSF rheumatoid arthritis foot and ankle scale (p < 0.0001). Forty-eight of the 50 ankles had no revision TAA surgery. Subsidence of the talar component was seen in 8 ankles (6 in the biologic treatment group and 2 in the non-biologic treatment group); 2 of these ankles (both in the biologic treatment group) underwent revision TAA. The social functioning score of the SAFE-Q scale at the time of the latest follow-up was significantly higher in the biologic treatment group (p = 0.0079). The dosage of prednisolone (p = 0.0003), rate of usage of prednisolone (p = 0.0001), and disease-activity score (p < 0.01) at the time of the latest follow-up were all significantly lower in the biologic treatment group. Conclusions:TAA is recommended for the treatment of rheumatoid arthritis if disease control, augmentation of bone strength, control of soft-tissue balance, and adjustment of the loading axis are taken into account. The prevention of talar component subsidence remains a challenge in patients with the combination of subtalar fusion, rheumatoid arthritis, and higher social activity levels. Level of Evidence:Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Project description:Accurate positioning of the total ankle arthroplasty implant components with the absence of any hindfoot deformity does not preclude the development of bony impingement. In cases of ankle stiffness after total ankle arthroplasty, the usual limitation is in dorsiflexion. If triceps surae contracture is excluded or persistent restriction remains in ankle dorsiflexion after gastrocnemius recession or tendo-Achilles lengthening, posterior ankle capsulectomy, debridement of posterior ankle gutter, and release of the deep posterior deltoid ligament and the posterior talofibular ligament are indicated. In this Technical Note, the technical details of endoscopic posterior ankle decompression and release after total ankle arthroplasty are described. Technique Video Video 1 Endoscopic posterior ankle decompression and release after total ankle arthroplasty of the left ankle. The patient is in the prone position. Posteromedial portal is the viewing portal and posterolateral portal is the working portal. The flexor hallucis longus (FHL) tendon is exposed. The arthroscope is switched to the posterolateral portal and the posterolateral ankle capsule is resected with arthroscopic instruments via the posteromedial portal. The FHL tendon is pushed medially by the instruments to facilitate resection of the more medial posterior ankle capsule. The arthroscope is switched back to the posteromedial portal and the most lateral part of the posterior ankle capsule is resected with arthroscopic shaver and radiofrequency wand via the posterolateral portal. Then, the FHL tendon is looped with a vascular sling via the posterolateral portal and the tendon is retracted laterally. The medial part of the posterior ankle capsule is resected with arthroscopic instruments via the posteromedial portal. The fibrous tissue of the posteromedial ankle gutter is also resected. The arthroscope is switched to the posteromedial portal and the fibrous tissue of the posterolateral ankle gutter is resected. The scarred posterolateral ankle ligamentous structure and fibrous band is released from its calcaneal insertion. The arthroscope is switched back to the posterolateral portal and the scarred posteromedial ankle ligamentous structure and fibrous band is carefully cut by a No. 15 scalpel with the cutting blade facing laterally.
