Abstract
Background Research on outcomes after ankle fusion focuses on basic activities of daily living, fusion rates, and gait parameters. Little has been reported on the patient’s perspective after surgery. The purpose of this study was to determine the change in patient reported physical function and pain interference after ankle fusion surgery to guide patient expectations and improve provider communication. Methods This was a retrospective review of prospectively collected patient reported outcome measurement information system (PROMIS) data in 88 ankle arthrodesis procedures performed from May 2015 to March 2018. The PROMIS Physical function (PF) and pain interference (PI) measures were collected as routine care. Linear mixed models were used to assess differences at each follow-up point for PF and PI. Preoperative to last follow-up in the 120–365 day interval was assessed using analysis of variance. Outcomes included T-scores, z-scores, and PROMIS-Preference (PROPr) utility scores for PF and PI and the percentage of patients improving by at least 4 T-score points. Results The linear mixed model analysis for PF after the 120–149 days, and for PI, after 90–119 days, indicated recovery plateaued at 39–40 for PF and 57–59 for PI T-scores. The change in the PI T-score was the greatest with a mean T-score improvement of − 5.4 (95% CI − 7.7 to − 3.1). The proportion of patients improving more than 4 points was 66.2% for either PF or PI or both. The change in utility T-scores for both PF (0.06, 95% CI 0.02 to 0.11) and PI (0.15, 95% CI 0.09 to 0.20) was significantly improved, however, only PI approached clinical significance. Conclusion Average patients undergoing ankle fusion experience clinically meaningful improvement in pain more so than physical function. Average patient recovery showed progressive improvement in pain and function until the four-month postoperative time point. Traditional dogma states that recovery after an ankle fusion maximizes at a year, however based on the findings in this study, 4 months is a more accurate marker of recovery. A decline in function or an increase in pain after 4 months from surgery may help to predict nonunion and other complications after ankle arthrodesis. Level of evidence Level II, prospective single cohort study.

Abstract
Researchers investigated pain perception in patients with diabetic foot ulcers (DFUs) by analyzing pre- and postoperative physical function (PF), pain interference (PI), and depression domains of the Patient-Reported Outcome Measurement Information System (PROMIS). They hypothesized that 1) because of painful diabetic peripheral neuropathy (DPN), a majority of patients with DFUs would have high PROMIS PI scores unchanged by operative intervention, and 2) the initially assessed PI, PF, and depression levels would be correlated with final outcomes. Seventy-five percent of patients with DFUs reported pain, most likely because of painful DPN. Those who reported high PI and low PF were likely to report depression. PF, PI, and depression levels were unchanged after operative intervention or healing of DFUs.

Abstract
BACKGROUND Prior studies have suggested preoperative patient-reported outcome scores could predict patients who would achieve a clinically meaningful improvement with hallux valgus surgery. Our goal was to determine bunionectomy-specific thresholds using Patient-Reported Outcomes Measurement Information System (PROMIS) values to predict patients who would or would not benefit from bunion surgery. METHODS PROMIS physical function (PF), pain interference (PI), and depression assessments were prospectively collected. Forty-two patients were included in the study. Using preoperative and final follow-up visit scores, minimally clinically important differences (MCID), receiver operating characteristic (ROC) curves, and area under the curve (AUC) analyses were performed to determine if preoperative PROMIS scores predicted achieving MCID with 95% specificity or failing to achieve an MCID with 95% sensitivity. RESULTS PROMIS PF demonstrated a significant AUC and likelihood ratio. The preoperative threshold score for failing to achieve MCID for PF was 49.6 with 95% sensitivity. The likelihood ratio was 0.14 (confidence interval, 0.02-0.94). The posttest probability of failure to achieve an MCID for PF was 94.1%. PI and depression AUCs were not significant, and thus thresholds were not determined. CONCLUSION We identified a PF threshold of 49.6, which was nearly 1 standard deviation higher than previously published. If a patient is hoping to improve PF, a patient with a preoperative t score >49.6 may not benefit from surgery. This study also suggests the need for additional research to delineate procedure-specific thresholds. LEVEL OF EVIDENCE Level III, retrospective comparative series.

Abstract
Background. Achilles tendinopathy is a common clinical disorder. Utilizing the Patient-Reported Outcomes Measurement Information System, we aim to determine clinical response to nonoperative achilles tendinopathy rehabilitative care of insertional achilles tendinopathy compared to non-insertional achilles tendinopathy. Methods. Prospective Patient-Reported Outcomes Measurement Information System Physical Function, Pain Interference, and Depression scores were collected for patients with achilles tendinopathy at presentation and following a standard course of nonoperative care. A distribution-based method was used to determine the minimal clinically important difference. Descriptive statistics were reported and bivariate analysis was used to compare insertional achilles tendinopathy and non-insertional achilles tendinopathy. Receiver operating characteristic curve analysis was used to predict clinical improvement. Results. A total of 102 patients with an average follow-up of 68 days were included. For the non-insertional achilles tendinopathy group: Fifteen (46%), 12 (36%) and 9 (27%) patients reached clinical improvement for Physical Function, Pain Interference and Depression, respectively. For the insertional achilles tendinopathy group: Seventeen (25%), 20 (29%) and 22 (32%) patients reached clinical improvement for Physical Function, Pain Interference and Depression, respectively. Physical Function scores improved more in non-insertional achilles tendinopathy patients (4.0 vs. -0.046; p = 0.035) and more patients clinically improved (45.5% vs. 24.6%; p = 0.034). Patients with non-insertional and insertional achilles tendinopathy clinically improved functionally when initial Physical Function scores were equal to or lower than 40.25 and 38.08, respectively. Conclusions. Nonoperative care in achilles tendinopathy is often successful. The Patient-Reported Outcomes Measurement Information System can be used to evaluate and help determine clinical success. Levels of Evidence: Level II: Prospective comparative study.

Abstract
BACKGROUND The Patient Reported Outcomes Information System (PROMIS) is an efficient metric able to detect changes in global health. PURPOSE To assess the responsiveness, convergent validity, and clinically important difference (CID) of PROMIS compared with disease-specific scales after knee arthroscopy. STUDY DESIGN Cohort study (Diagnosis); Level of evidence, 2. METHODS A prospective institutional review board-approved study collected PROMIS Physical Function (PF), PROMIS Pain Interference (PI), International Knee Documentation Committee (IKDC), and Knee injury and Osteoarthritis Outcome Score (KOOS) results in patients undergoing knee arthroscopy. The change from preoperative to longest follow-up was used in analyses performed to determine responsiveness, convergent validity, and minimal and moderate CID using the IKDC scale as the anchor. RESULTS Of the 100 patients enrolled, 76 were included. Values of the effect size index (ESI) ranged from near 0 to 1.69 across time points and were comparable across scales. Correlations of the change in KOOS and PROMIS with IKDC ranged from r values of 0.61 to 0.79. The minimal CID for KOOS varied from 12.5 to 17.5. PROMIS PF and PI minimal CID were 3.3 and -3.2. KOOS moderate CID varied from 14.3 to 18.8. PROMIS PF and PI moderate CID were 5.0 and -5.8. CONCLUSION The PROMIS PF and PI showed similar responsiveness and CID compared with disease-specific scales in patients after knee arthroscopy. PROMIS PI, PROMIS PF, and KOOS correlations with IKDC demonstrate that these scales are measuring a similar construct. The ESIs of PROMIS PF and PI were similar to those of KOOS and IKDC, suggesting similar responsiveness at 6 months or longer (ESI >1.0). Minimum and moderate CID values calculated for PROMIS PF and PI using IKDC as an anchor were sufficiently low to suggest clinical usefulness. CLINICAL RELEVANCE PROMIS PF and PI can be accurately used to determine improvement or lack thereof with clinically important changes after knee arthroscopy.

Abstract
BACKGROUND: A prospective, randomized, noninferiority clinical trial of synthetic cartilage implant hemiarthroplasty for hallux rigidus demonstrated functional outcomes and safety equivalent to first metatarsophalangeal (MTP) joint arthrodesis at 24 months. We prospectively assessed safety and efficacy outcomes for synthetic cartilage implant hemiarthroplasty at a minimum of 5 years. METHODS: Of 135 eligible patients from the original trial, 112 (83.0%) were enrolled (mean age, 58.2 ± 8.8 years; 87 females). Pain visual analog scale (VAS), Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL), and FAAM Sports subscales were completed preoperatively and 2 and 5 years postoperatively. Great toe active dorsiflexion, weightbearing radiographs, secondary procedures, and safety parameters were also evaluated. RESULTS: At 24 months, 14/152 (9.2%) patients had undergone implant removal and conversion to arthrodesis. In years 2 to 5, 9/119 (7.6%) patients underwent implant removal and conversion to arthrodesis. At mean 5.8 ± 0.7 (range, 4.4-8.0) years' follow-up, pain VAS, FAAM ADL, and FAAM Sports scores improved by 57.9 ± 18.6 points, 33.0 ± 17.6 points, and 47.9 ± 27.1 points, respectively, from baseline. Clinically significant changes in VAS pain, FAAM ADL, and FAAM Sports were reported by 103/106 (97.2%), 95/105 (90.5%), and 97/104 (93.3%) patients, respectively. Patient-reported outcomes at 24 months were maintained at 5.8 years in patients who were not revised. Active MTP joint peak dorsiflexion was maintained. Ninety-nine of 106 (93.4%) patients would have the procedure again. CONCLUSION: Clinical and safety outcomes for synthetic cartilage implant hemiarthroplasty observed at 2 years were maintained at 5.8 years. The implant remains a viable treatment option to decrease pain, improve function, and maintain motion for advanced hallux rigidus. LEVEL OF EVIDENCE: Level IV, case series.

Abstract
OBJECTIVES The Patient-Reported Outcomes Measurement Information System (PROMIS) is growing in popularity as healthcare shifts towards a value-based system. However, it remains unclear if PROMIS use improves the patient experience. The aim of the present study was to determine if PROMIS use as part of routine orthopaedic clinical care is associated with improved patient experience, as measured by the Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CGCAHPS) survey. METHODS All patient visits to an orthopaedic surgery clinic at a single academic medical centre between February 2015 and September 2016 were reviewed. Accounting for known patient factors that have an impact on clinic visit satisfaction, CGCAHPS scores were compared between patients who had PROMIS used as part of their routine care and those who had not had PROMIS used as part of their routine care. A p-value of <0.05 was considered significant. RESULTS A total of 8,607 patient visits fitted our inclusion criteria. Of these, surgeons elected not to use PROMIS in 8,422 patient encounters, leaving 185 patient visits in which PROMIS was actively used. When PROMIS was used, patients were significantly more likely to feel that the provider had spent enough time with them, to recommend this provider office to another patient and to rate the provider significantly higher on a scale from 0 to 10. Although not significant, a trend was found between use of PROMIS and whether a patient felt that a provider explained health information in way that the patient understood. CONCLUSIONS PROMIS use in an orthopaedic clinic visit can have a positive impact on the patient experience, which is currently part of a number of alternative payment models.

Abstract
BACKGROUND: The Numeric Pain Rating Scale (NPRS) is a popular method to assess pain. Recently, the Patient-Reported Outcomes Measurement Information System (PROMIS) has been suggested to be more accurate in measuring pain. This study aimed to compare NPRS and PROMIS Pain Interference (PI) scores in a population of foot and ankle patients to determine which method demonstrated a stronger correlation with preoperative and postoperative function, as measured by PROMIS Physical Function (PF). METHODS: Prospective PROMIS PF and PI and NPRS data were obtained for 8 common elective foot and ankle surgical procedures. Data were collected preoperatively and postoperatively at a follow-up visit at least 6 months after surgery. Spearman correlation coefficients were calculated to determine the relationship among NPRS (0-10) and PROMIS domains (PI, PF) pre- and postoperatively. A total of 500 patients fit our inclusion criteria. RESULTS: PROMIS PF demonstrated a stronger correlation to PROMIS PI in both the pre- and postoperative settings (preoperative: ρ = -0.66; postoperative: ρ = -0.69) compared with the NPRS (preoperative: ρ = -0.32; postoperative:ρ = -0.33). Similar results were found when data were grouped by Current Procedural Terminology (CPT) code. CONCLUSION: PROMIS PI was a superior tool to gauge a patient's preoperative level of pain and functional ability. This information may assist surgeons and patients in setting postoperative functional expectations and pain management. LEVEL OF EVIDENCE: Level II, prognostic.

Abstract
BACKGROUND: The knee scooter is a commonly used mobility device in the setting of unilateral below-knee immobilization. The bent-knee posture has been shown to decrease venous flow in a seated position, but the knee scooter differs as the patient is weightbearing through the affected extremity. Our goal was to investigate the effects of knee scooter positioning on popliteal venous flow. METHODS: Duplex ultrasonography was performed to obtain venous diameter and flow velocity of the popliteal vein on healthy subjects over the age of 18 without immobilization. Measurements were performed on the left knee of each subject while standing and with the same knee flexed on the knee scooter, by 2 physicians trained in ultrasound techniques. Mean velocity, peak velocity, vessel diameter, and volumetric flow rate were calculated and t tests were performed for each variable. A power analysis was performed, determining that 9 subjects would provide 80% power with an alpha of 0.05. A total of 13 subjects participated in the study. Mean age was 33 (range 20-56) years, with 6 females and 7 males. RESULTS: Measurements of subjects while standing and on the knee scooter demonstrated a significant decrease in mean velocity (6.5 vs 3.2 cm/s, P < .01) and volumetric flow rate (227.8 vs 106.2 mL/min, P < .01) while subjects were using the scooter. Vessel diameter (0.82 vs 0.78 cm, P = .15) and peak velocities (19.8 vs 14.7 cm/s, P = .19) were not significantly different between standing and kneeling positions. CONCLUSION: Our findings demonstrated a statistically significant decrease in volumetric flow rate in subjects using a knee scooter device with a flexed knee. Although venous stasis is a known risk factor for DVT, flow rate thresholds for increased thrombus formation are not well defined. The duration of scooter use, or flexed knee positioning, may have some effect on the degree of stasis. This finding should caution orthopedists to consider the risk attributed to the knee scooter as part of their overall patient assessment. LEVEL OF EVIDENCE: Level II, therapeutic, comparative study.

Abstract
BACKGROUND: Investigating the responsiveness of an instrument is important in order to provide meaningful interpretation of clinical outcomes. This study examined the responsiveness of the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF), the PROMIS Pain Interference (PI), and the Foot and Ankle Ability Measure (FAAM) Sports subscale in an orthopedic sample with foot and ankle ailments. METHODS: Patients presenting to an orthopedic foot and ankle clinic during the years 2014-2017 responded to the PROMIS and FAAM instruments prior to their clinical appointments. The responsiveness of the PROMIS PF v1.2, PROMIS PI v1.1, and FAAM Sports were assessed using paired samples t test, effect size (ES), and standardized response mean (SRM) at 4 different follow-up points. A total of 785 patients with an average age of 52 years (SD = 17) were included. RESULTS: The PROMIS PF had ESs of 0.95 to 1.22 across the 4 time points (3, >3, 6, and <6 months) and SRMs of 1.04 to 1.43. The PROMIS PI had ESs of 1.04 to 1.63 and SRMs of 1.17 to 1.23. For the FAAM Sports, the ESs were 1.25 to 1.31 and SRMs were 1.07 to 1.20. The ability to detect changes via paired samples t test provided mixed results. But in general, the patients with improvement had statistically significant improved scores, and the worsening patients had statistically significant worse scores. CONCLUSION: The PROMIS PF, PROMIS PI, and FAAM Sports were sensitive and responsive to changes in patient-reported health. LEVEL OF EVIDENCE: Level II, prospective comparative study.

Abstract
Patient-reported outcomes measures (PROM) have become increasingly emphasized in the transition from volume-based to value-based orthopaedic care. Incorporation of PROM collection into daily clinical practice can be challenging, however, because of financial and logistic constraints. In modern orthopaedics, PROM are important and can be successfully and practically incorporated into clinical practice.

Abstract
BACKGROUND: Establishing score points that reflect meaningful change from the patient perspective is important for interpreting patient-reported outcomes. This study estimated the minimum clinically important difference (MCID) values of 2 Patient-Reported Outcomes Measurement Information System (PROMIS) instruments and the Foot and Ankle Ability Measure (FAAM) Sports subscale within a foot and ankle orthopedic population. METHODS: Patients seen for foot and ankle conditions at an orthopedic clinic were administered the PROMIS Physical Function (PF) v1.2, the PROMIS Pain Interference (PI) v1.1, and the FAAM Sports at baseline and all follow-up visits. MCID estimation was conducted using anchor-based and distribution-based methods. RESULTS: A total of 3069 patients, mean age of 51 years (range = 18-94), were included. The MCIDs for the PROMIS PF ranged from approximately 3 to 30 points (median = 11.3) depending on the methods being used. The MCIDs ranged from 3 to 25 points (median = 8.9) for the PROMIS PI, and from 9 to 77 points (median = 32.5) for the FAAM Sports. CONCLUSIONS: This study established a range of MCIDs in the PROMIS PF, PROMIS PI, and FAAM Sports indicating meaningful change in patient condition. MCID values were consistent across follow-up periods, but were different across methods. Values below the 25th percentile of MCIDs may be useful for low-risk clinical decisions. Midrange values (eg, near the median) should be used for high stakes decisions in clinical practice (ie, surgery referrals). The MCID values within the interquartile range should be utilized for most decision making. LEVEL OF EVIDENCE: Level I, diagnostic study, testing of previously developed diagnostic measure on consecutive patients with reference standard applied.

Abstract
Synthetic cartilage implant surgery is an excellent option for the patient with great toe arthritis and good alignment of the toe who wishes to retain first metatarsophalangeal motion and obtain 90% improved pain relief and function. Patients with osteoporosis, osteopenia, or bone defects from surgery or disease may not maintain the implant position due to poor bone quality, resulting in less than desired outcomes. Despite this being a straightforward surgery, patients need to be aware that the pain relief may not begin until 3+ months after surgery because this procedure does require bone resection and implant placement.

Abstract
BACKGROUND First metatarsophalangeal joint (MTPJ1) hemiarthroplasty using a novel synthetic cartilage implant was as effective and safe as MTPJ1 arthrodesis in a randomized clinical trial. We retrospectively evaluated operative time and recovery period for implant hemiarthroplasty (n=152) and MTPJ1 arthrodesis (n=50). METHODS Perioperative data were assessed for operative and anaesthesia times. Recovery and return to function were prospectively assessed with the Foot and Ankle Ability Measure (FAAM) Sports and Activities of Daily Living (ADL) subscales and SF-36 Physical Functioning (PF) subscore. RESULTS Mean operative time for hemiarthroplasty was 35±12.3min and 58±21.5min for arthrodesis (p<0.001). Anaesthesia duration was 28min shorter with hemiarthroplasty (p<0.001). At weeks 2 and 6 postoperative, hemiarthroplasty patients demonstrated clinically and statistically significantly higher FAAM Sport, FAAM ADL, and SF-36 PF subscores versus arthrodesis patients. CONCLUSION MTPJ1 hemiarthroplasty with a synthetic cartilage implant took less operative time and resulted in faster recovery than arthrodesis.

Abstract
BACKGROUND As the role of generic patient-reported outcomes (PROs) expands, important questions remain about their interpretation. In particular, how the Patient Reported Outcome Measurement Instrumentation System (PROMIS) t score values correlate with the patients' perception of success or failure (S/F) of their surgery is unknown. The purposes of this study were to characterize the association of PROMIS t scores, the patients' perception of their symptoms (patient acceptable symptom state [PASS]), and determination of S/F after surgery. METHODS This retrospective cohort study contacted patients after the 4 most common foot and ankle surgeries at a tertiary academic medical center (n = 88). Patient outcome as determined by phone interviews included PASS and patients' judgment of whether their surgery was a S/F. Assessment also included PROMIS physical function (PF), pain interference (PI), and depression (D) scales. The association between S/F and PASS outcomes was evaluated by chi-square analysis. A 2-way analysis of variance (ANOVA) evaluated the ability of PROMIS to discriminate PASS and/or S/F outcomes. Receiver operator curve (ROC) analysis was used to evaluate the ability of pre- (n = 63) and postoperative (n = 88) PROMIS scores to predict patient outcomes (S/F and PASS). Finally, the proportion of individuals classified by the identified thresholds were evaluated using chi-square analysis. RESULTS There was a strong association between PASS and S/F after surgery (chi-square <0.01). Two-way ANOVA demonstrated that PROMIS t scores discriminate whether patients experienced positive or negative outcome for PASS ( P < .001) and S/F ( P < .001). The ROC analysis showed significant accuracy (area under the curve > 0.7) for postoperative but not preoperative PROMIS t scores in determining patient outcome for both PASS and S/F. The proportion of patients classified by applying the ROC analysis thresholds using PROMIS varied from 43.0% to 58.8 % for PASS and S/F. CONCLUSIONS Patients who found their symptoms and activity at a satisfactory level (ie, PASS yes) also considered their surgery a success. However, patients who did not consider their symptoms and activity at a satisfactory level did not consistently consider their surgery a failure. PROMIS t scores for physical function and pain demonstrated the ability to discriminate and accurately predict patient outcome after foot and ankle surgery for 43.0% to 58.8% of participants. These data improve the clinical utility of PROMIS scales by suggesting thresholds for positive and negative patient outcomes independent of other factors.

Abstract
BACKGROUND A recent publication reported preoperative Patient-Reported Outcomes Measurement Instrumentation System (PROMIS) scores to be highly predictive in identifying patients who would and would not benefit from foot and ankle surgery. Their applicability to other patient populations is unknown. The aim of this study was to assess the validation and generalizability of previously published preoperative PROMIS physical function (PF) and pain interference (PI) threshold t scores as predictors of postoperative clinically meaningful improvement in foot and ankle patients from a geographically unique patient population. METHODS Prospective PROMIS PF and PI scores of consecutive patient visits to a tertiary foot and ankle clinic were obtained between January 2014 and November 2016. Patients undergoing elective foot and ankle surgery were identified and PROMIS values obtained at initial and follow-up visits (average, 7.9 months). Analysis of variance was used to assess differences in PROMIS scores before and after surgery. The distributive method was used to estimate a minimal clinically important difference (MCID). Receiver operating characteristic curve analysis was used to determine thresholds for achieving and failing to achieve MCID. To assess the validity and generalizability of these threshold values, they were compared with previously published threshold values for accuracy using likelihood ratios and pre- and posttest probabilities, and the percentages of patients identified as achieving and failing to achieve MCID were evaluated using χ2 analysis. RESULTS There were significant improvements in PF ( P < .001) and PI ( P < .001) after surgery. The area under the curve for PF (0.77) was significant ( P < .01), and the thresholds for achieving MCID and not achieving MCID were similar to those in the prior study. A significant proportion of patients (88.9%) identified as not likely to achieve MCID failed to achieve MCID ( P = .03). A significant proportion of patients (84.2%) identified as likely to achieve MCID did achieve MCID ( P < .01). The area under the curve for PROMIS PI was not significant. CONCLUSIONS PROMIS PF threshold scores from published data were successful in classifying patients from a different patient and geographic population who would improve with surgery. If functional improvement is the goal, these thresholds could be used to help identify patients who will benefit from surgery and, most important, those who will not, adding value to foot and ankle health care.

Abstract
Category: Midfoot/Forefoot Introduction/Purpose: Hallux rigidus is the most common arthritic condition of the foot. A prospective, randomized, non-inferiority clinical trial of first metatarsophalangeal joint (MTPJ) hemiarthroplasty with a synthetic polyvinyl alcohol hydrogel implant, for moderate to severe hallux rigidus, demonstrated maintenance of MTPJ active dorsiflexion motion and excellent pain relief; additionally, the trial showed functional outcomes and safety equivalent to first MTPJ arthrodesis at 24 months (Baumhauer et al. 2016; FAI:37(5):457-469). Recognizing that many hemiarthroplasty and total toe implants have initially good results that deteriorate over time, the purpose of this study was to prospectively assess the safety and efficacy outcomes for the synthetic cartilage implant population and to determine if the excellent outcomes were maintained at >5 years. Methods: One hundred and fifty-two patients underwent implant hemiarthroplasty in the original trial; 14 underwent implant removal and conversion to fusion and 3 were lost to follow-up during the first 24 months, leaving 135 eligible for this study. One hundred patients were evaluated at 5+ years; 5 could not be reached for follow-up. Thirty are pending consent, follow-up, and/or data entry; their status will be available for inclusion at the conference presentation. Patients completed a pain visual analogue scale (VAS) and Foot and Ankle Ability Measure (FAAM) Sports and Activities of Daily Living (ADL) scores, preoperatively and at 2, 6, 12, 26, 52, 104 and 260 weeks postoperatively. Minimal clinically important differences are: =30% difference for pain VAS, 9 points for FAAM Sports, and 8 points for FAAM ADL. Great toe active dorsiflexion, weight-bearing radiographs, secondary procedures, and safety parameters were evaluated. Results: Of 100 synthetic cartilage implant hemiarthroplasty patients available at mean 5.8 years follow-up (SD ±0.7; range: 4.4- 7.4), 5 underwent implant removal and conversion to fusion in years 2-5 (Figure 1), and 2 underwent subsequent surgical interventions during the pivotal trial and were censored, leaving 93 patients for evaluation. Pain and function outcomes observed at 5.8 years were similar to those at 2 years (Figure 1). VAS Pain and FAAM Sports Scores were maintained or improved at 5.8 years follow-up, but these differences were not clinically significant. Joint motion was maintained at 5.8 years. No evidence of avascular necrosis, device migration or fragmentation was observed upon independent radiographic review. Eighty-six percent of patients agreed their overall well-being had improved, and 92% would have the procedure again. Conclusion: Clinical and safety outcomes of patients having undergone synthetic cartilage implant hemiarthroplasty for the surgical treatment of hallux rigidus were previously demonstrated to be non-inferior to the gold standard treatment, MTPJ fusion, at 2 years. Prospectively determined outcomes for 100/135 of these implant hemiarthroplasty patients at 5.8 years are similar to those reported at 2 years. Longer-term results demonstrate that clinical and safety outcomes for synthetic cartilage implant hemiarthroplasty are durable, and that the implant remains a viable treatment option to decrease pain, improve function and maintain motion for advanced hallux rigidus.

Abstract
Arthritis of the first metatarsophalangeal (MTP) joint, hallux rigid, is a common and disabling source of foot pain in the adult population. Hallux rigidus is characterized by diseased cartilage and large, periarticular osteophytes that result in a stiff, painful joint. Activity modification, sensible shoes, orthotics, anti-inflammatory medications and occasional intra-articular steroid injections can be attempted to alleviate the discomfort associated with hallux rigidus. A number of surgical options exist for the treatment of recalcitrant hallux rigidus. Cheilectomy is a useful treatment for dorsal impingement pain seen in mild hallux rigidus. A new polyvinyl alcohol hemi-arthroplasty implant has shown promising early and midterm results in the treatment of advanced hallux rigidus; however, arthrodesis of the first MTP joint remains the gold standard treatment for advanced hallux rigidus because of unpredictable outcomes after early-generation joint replacement implants.

Abstract
BACKGROUND Grading systems are used to assess severity of any condition and as an aid in guiding treatment. This study examined the relationship of baseline motion, pain, and observed intraoperative cartilage loss with hallux rigidus grade. METHODS A prospective, randomized study examining outcomes of arthrodesis compared to synthetic cartilage implant was performed. Patients underwent preoperative clinical examination, radiographic assessment, hallux rigidus grade assignment, and intraoperative assessment of cartilage loss. Visual analog scale (VAS) score for pain was obtained preoperatively and at 24 months. Correlation was made between active peak dorsiflexion, VAS pain, cartilage loss, and hallux rigidus grade. Fisher's exact test was used to assess grade impact on clinical success ( P < .05). RESULTS In 202 patients, 59 (29%), 110 (55%), and 33 (16%) were classified as Coughlin grades 2, 3, and 4, respectively. There was no correlation between grade and active peak dorsiflexion (-0.069, P = .327) or VAS pain (-0.078, P = .271). Rank correlations between grade and cartilage loss were significant, but correlations were small. When stratified by grade, composite success rates between the 2 treatments were nearly identical. CONCLUSIONS Irrespective of the grade, positive outcomes were demonstrated for both fusion and synthetic cartilage implant. Clinical symptoms and signs should be used to guide treatment, rather than a grade consisting of radiographic, symptoms, and range of motion factors.
