The comparison analysis of resection interposition arthroplasty and implant arthroplasty in hallux rigidus surgery

Aim Hallux rigidus is a condition characterized by pain and limited dorsiflexion, resulting from progressive degenerative arthritis of the first metatarsophalangeal joint. This study aimed to evaluate the superiority of surgical techniques in the treatment of advanced-stage hallux rigidus patients. Methods Study participants included 19 feet from 19 patients. Demographic information of the patients was collected. The first MTP joint ROM and the AOFAS scores were recorded. AOFAS and 1st MTP joint ROM obtained in both groups were statistically significant. Results In patients who underwent IA and RIA, there was no significant difference in preoperative and postoperative 1st MTP joint flexion range of motion (<em>P</em> = .123, 0.072). Significant differences were observed in preoperative and postoperative 1st MTP joint extension motion in patients who underwent IA (<em>P</em> = .023) and in those who underwent RIA (<em>P</em> = .027). There was a significant difference in preoperative and postoperative AOFAS scores in patients who underwent both IA and RIA (<em>P</em> < .001, <em>P</em> = .003). There was no statistically significant difference between the two groups in postoperative values of AOFAS, MTP Flexion Angle, and MTP Extension Angle (<em>P</em> > .05) Conclusion The results of this study indicate a significant effect on postoperative extension angles and AOFAS scores in patients who underwent both IA and RIA. However, no statistically significant difference was found between the two operations in postoperative 1st MTP joint flexion, 1st MTP joint extension, or AOFAS scores.
