Introduction/Purpose: Current literature shows similar clinical outcomes between first metatarsophalangeal joint arthrodesis and polyvinyl alcohol hydrogel (synthetic cartilage implant or SCI) hemiarthroplasty in the treatment of hallux rigidus; however, prior studies have not reported validated patient-reported outcome measures. To our knowledge, this is the first study to compare patient-reported outcome measures using the validated Patient Reported Outcomes Measurement Information System (PROMIS) in patients treated for hallux rigidus with metatarsophalangeal joint arthrodesis and SCI hemiarthroplasty. In addition, this novel study provides comparative data of the complication and revision rates for each procedure. Methods: A retrospective review of prospectively collected data within an institutional registry identified 101 patients who underwent metatarsophalangeal joint arthrodesis and 82 patients who underwent SCI hemiarthroplasty for treatment of hallux rigidus between January 2016 and June 2022. Chart review was performed to obtain demographic information, complications, and revision rates. Preoperative, 1-year, and 2-year PROMIS scores were obtained from the registry and confirmed via chart review. Equivalence testing was performed using two one sided t-tests (TOST) and setting a +/-5 unit margin of difference as the clinically meaningful difference to determine if there was a difference in PROMIS scores between groups. Linear regression models were also utilized to compare adjusted postoperative PROMIS scores between the two cohorts. For the equivalence testing, a p-value > 0.05 indicated a statistically significant result. Results: Demographic information and preoperative hallux rigidus severity between the cohorts showed no statistically significant difference (Table 1). The SCI cohort had no intra-operative or post-operative wound complications, but one patient within the MTP fusion cohort was treated for a superficial wound infection. The SCI group had six patients revised to MTP fusions within 3-years due to continued pain and/or implant subsidence. The MTP fusion group had 2 patients revised due to non-union and 13 patients that had symptomatic hardware requiring removal. Equivalence comparison of PROMIS scores showed the SCI cohort had significantly worse pain intensity scores at 2 years and significantly less improvement in pain intensity scores from pre-operative to 1-year post-op (Table 2). There were no differences found between cohorts for other PROMIS domains. Conclusion: For the treatment of hallux rigidus, the SCI hemiarthroplasty and metatarsophalangeal joint arthrodesis have equivalent outcomes for all PROMIS domains except the pain intensity domain. While patients in both cohorts had improvement in pain from pre-operative to post-operative time points, SCI was not as effective as first MTP fusion at relieving pain intensity at a follow-up of 2 years. While SCI is a motion-sparing procedure, patients with a primary goal of improving pain may be better suited for first MTP joint arthrodesis. [ABSTRACT FROM AUTHOR]

Introduction/Purpose: Physical activity and returning to sports are vital for athletes after foot and ankle surgery. While joint preservation is preferred, joint arthrodesis becomes necessary in certain injuries or deformities. Common procedures include Lisfranc arthrodesis, modified Lapidus for hallux valgus (HV), and first metatarsophalangeal (MTP) arthrodesis for hallux rigidus (HR), addressing pain and deformities. Prior studies show promising outcomes individually, yet lack comparisons, impeding understanding of postoperative differences in function. Comparative insights can guide patient expectations and shared decisions pre-surgery. Thus, this retrospective study aims to compare clinical outcomes and return to sports in the three procedure groups. Methods: Between 2006 and 2014, a study assessed 48 modified Lapidus procedures for HV (average age 37.3 years, average follow-up 2.8 years, 95.8% female), 38 Lisfranc injuries (average age 31.8 years, average follow-up 5.2 years, 47.4% female), and 50 MTP fusion for HR cases (average age 54.9 years, average follow-up 5.1 years, 66% female). The assessment focused on physical activity and return to sport, utilizing sports-specific, patient-administered questionnaires. Clinical outcomes were evaluated through the Foot and Ankle Outcome Score (FAOS), encompassing pain, symptoms, stiffness, daily function, sports function, and quality of life. Comparison among the surgical groups included return-to-activity difficulty, participation levels, postoperative FAOS scores, and patient satisfaction. ANOVA analysis gauged significance in FAOS subscale differences among procedures, followed by the Tukey HSD test to pinpoint specific procedure variations if significant differences arose. Results: Regarding FAOS scores, the procedures yielded similar outcomes in the pain subscale. No differences between Lapidus-Lisfranc in the symptom subscale (P=0.6). However, MTP fusion displayed poorer scores than Lapidus (P=0.04) and Lisfranc (P=0.005). No differences between Lapidus-Lisfranc (P=0.64) and Lapidus-MTP Fusion in Activities of Daily Living (P=0.18). Yet, MTP fusion exhibited notably worse outcomes than Lisfranc (P=0.03). For Sports, no differences between Lapidus-Lisfranc (P=0.94), while MTP fusion showed inferior outcomes to Lapidus (P=0.002) and Lisfranc (P=0.001). Although means varied, no differences were observed for Lapidus vs. Lisfranc (P=0.95), Lapidus vs. MTP Fusion (P=0.09), or Lisfranc vs. MTP fusion (P=0.06) in Quality of Life [Table 1]. Collectively, patients engaged in 40 activities. Return to sport post-surgery percentage, compared among procedure groups, yielded similar outcomes [Table 2]. Conclusion: Although all procedure groups had similar overall return to sports and physical activities patient satisfaction rates, there were significant differences in regard to FAOS scores. Lapidus and Lisfranc procedures displayed similar postoperative outcomes in all FAOS domains. MTP Fusion showed similar postoperative outcomes to both Lapidus and Lisfranc procedures in the FAOS pain and quality of life domains, however displayed significantly worse outcomes in symptoms, activities of daily living, and sports domains. Therefore, it appears that an MTP fusion results in more functional limitations when compared to Lapidus and Lisfranc procedures. [ABSTRACT FROM AUTHOR]

Background: Both an open cheilectomy with a Moberg osteotomy and percutaneous cheilectomy have been successfully used to treat hallux rigidus and preserve motion.However, there have been no studies that have compared these 2 procedures using validated patient-reported outcomes such as the Patient Reported Outcome Measurement Information System., Methods: A retrospective review of hallux rigidus patients between January 2016 and July 2021 collected 48 percutaneous cheilectomy (PC) patients and 71 open cheilectomy with Moberg (OCM) patients. Preoperative and minimum 1-year postoperative PROMIS scores were collected., Results: The OCM and PC cohorts did not have significant differences in their postoperative PROMIS scores. Both cohorts had modest but significant improvements postoperatively in the physical function, pain interference, and pain intensity domains. The OCM group had a larger degree of improvement in physical function, pain interference, and pain intensity ( P  = .015, .011, .001, respectively). No significant difference was identified in the reoperation rate., Conclusion: Patients undergoing an OCM had worse preoperative PROMIS scores and a modestly greater change in patient-reported outcomes than patients undergoing a PC., Level of Evidence: Level III, retrospective review., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The current literature shows similar clinical outcomes between first metatarsophalangeal (MTP) joint arthrodesis and synthetic cartilage implant (SCI) hemiarthroplasty in the treatment of hallux rigidus; however, prior studies have not reported validated patient-reported outcome measures (PROMs). To our knowledge, this is the first study to compare PROMs using 6 domains of the validated Patient-Reported Outcomes Measurement Information System (PROMIS) in patients treated for hallux rigidus with MTP joint arthrodesis and with SCI hemiarthroplasty. In addition, this novel study provides comparative data on the complication and revision rates for each procedure., Methods: A single-center, retrospective registry search identified all patients with preoperative PROMIS scores who underwent MTP joint arthrodesis or SCI hemiarthroplasty for hallux rigidus between February 2016 and June 2021. The study aimed to determine if the 2 procedures showed statistically or clinically equivalent PROMIS scores in 6 domains: physical function, pain interference, pain intensity, global physical health, global mental health, and depression. A multivariable linear regression analysis was performed to compare adjusted 1-year postoperative PROMIS scores between the 2 cohorts. Complication and revision rates were also compared., Results: The study included 82 patients who underwent SCI hemiarthroplasty and 101 who underwent MTP joint arthrodesis. Demographic data and preoperative hallux rigidus severity showed no significant differences between the cohorts. PROMIS scores were mostly comparable between the 2 groups, except for the pain intensity domain. The patients who underwent MTP joint arthrodesis exhibited significantly better pain relief at 1 and 2 years postoperatively, which was supported by adjusted postoperative PROMIS scores. At 2 years, the SCI group had worse pain intensity scores and lower global physical health scores. There were no differences between the cohorts in additional PROMIS scores or complication data., Conclusions: While outcomes in most of the domains were similar, MTP joint arthrodesis was more effective at mitigating pain intensity compared with SCI hemiarthroplasty. This information can guide patient counseling and decision-making when considering surgical intervention for hallux rigidus., Level of Evidence: Therapeutic Level III.

Background: Hallux valgus deformity affects more than 35% of people aged ≥65 years. Surgical correction in this population can be more complicated because of poor bone quality, worse deformity, and postoperative recovery challenges. The purpose of this study was to compare the radiographic and clinical outcomes of patients aged ≥65 years who underwent either open Lapidus or minimally invasive chevron Akin osteotomy for bunion correction., Methods: A retrospective review identified 62 patients aged ≥65 years who were treated surgically for hallux valgus with at least 1-year postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) scores (physical function and pain interference). Preoperative and at least 6-month postoperative radiographs were measured for the hallux valgus angle and intermetatarsal angle. PROMIS scores were obtained preoperatively and at 1 and/or 2 years postoperatively. Differences in demographic, clinical, and radiographic outcomes were assessed using the Mann Whitney U test and P values were adjusted for a false discovery rate of 5%., Results: There was no difference between the MIS and open cohorts in pre- or postoperative radiographic measurements or clinical outcomes at any time point. At 1 year postoperatively, both groups had statistically significant improvements in the PROMIS pain interference domain but only the MIS group had a statistically significant improvement in the PROMIS physical function domain. Clinical significance was equivocal. At 2 years postoperatively, there were clinically and statistically significant improvements in the PROMIS pain interference and physical function domains for the open and MIS groups., Conclusion: Patients in both surgical groups had improvement in radiographic measurements and 2-year PROMIS scores, although there was no clinical or statistical difference found between groups. MIS and open surgical techniques appear to be safe and effective in correcting hallux valgus in older patients; however, patients may need to be counseled that maximum improvement after surgery may take more than 1 year., Level of Evidence: Level III, retrospective cohort study., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: A.
