| Summary: | Category: Midfoot/Forefoot; Other Introduction/Purpose: Hallux rigidus is a degenerative condition of first metatarso-phalangeal joint, affecting people at all ages, but more commonly above 50 years of age. Multiple options are available to alleviate pain and improve movements of big toe. These include cheilectomy with Moberg osteotomy, silastic implants, ceramic and metal arthroplasties, hemiarthroplasties with Co-Cr and titanium implants with varying success. The aim of our study is to evaluate the midterm outcome of synthetic cartilage implant (SCI - Cartiva) arthroplasty for hallux rigidus. Methods: There were a total of 70 patients who underwent SCI interpositional arthroplasty. The five-year functional scores for all patients were collected and analysed. The functional evaluation was done using Manchester-Oxford Foot Questionnaire (MOxFQ). The general health was assessed by EQ-5D which included EQVAS. The data was obtained from hospital digital database Medway and Amplitude clinical outcomes. This was analysed by an independent assessor who was not involved in the patients’ care. The complications and revision rates were also documented. Results: Mean age at the time of operation was 63.4 years (range 42–84 years). The mean follow-up was 62.6 months. At five years follow up, 90% of the patients were satisfied with the outcome. The average preoperative MOxFQ score improved from 36.8 to 19.3 at one year after surgery. The EQ-5D scores improved from preoperative average of 9.4 to 4.4 at one year. The preoperative EQVAS was 75 and 85 at one year. At five years follow up the average MOxFQ score was 17.6, EQ-5D - 4.8 and EQVAS - 80. None of the patients had any infection. Three patients out of 70 had revision to first MTP fusion due to ongoing pain. Figure 1 shows the survival curve of the SCI implant at five years. Conclusion: Long term outcomes of Cartiva demonstrate clinical efficacy of this synthetic implant. The implant is durable, safe and is a viable treatment option to decrease pain, improve function and maintain motion for advanced hallux rigidus. |
