    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 patientsā€™ 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 patientsā€™ 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 patientsā€™ 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 \u3c0.01). Two-way ANOVA demonstrated that PROMIS t scores discriminate whether patients experienced positive or negative outcome for PASS (P \u3c .001) and S/F (P \u3c .001). The ROC analysis showed significant accuracy (area under the curve \u3e 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.

    PROMIS Pain Interference Is Superior vs Numeric Pain Rating Scale for Pain Assessment in Foot and Ankle Patients

    Full text link
    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: Ļ = āˆ’0.66; postoperative: Ļ = āˆ’0.69) compared with the NPRS (preoperative: Ļ = āˆ’0.32; postoperative: Ļ = āˆ’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 patientā€™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, prognosti

    Is there a Difference in Outcomes between Patients who Received a Double or Triple Arthrodesis for Hindfoot Arthritis?

    Full text link
    Introduction/Purpose: Triple arthrodesis has historically been considered the standard of treatment for arthritis of the hindfoot with or without deformity. The complications of this surgery including non-union, malunion, nerve injury, infection and wound healing problems can occur at any of the three joints. Double arthrodesis is capable of producing a similar reduction in degrees of motion and correction of foot deformity but may also cause less patient morbidity in regard to these complications due to one less joint being incorporated into the fusion procedure. What is unknown is the patient reported outcomes, specifically physical function (PF) and pain interference (PI) between these two procedures. The purpose of this study is to evaluate the clinical outcomes for hindfoot deformity using a triple compared to a double arthrodesis

    No full text
    Chronic ankle pain can be due to multiple causes. A thorough review of the patient\u27s history with a physical examination concentrating on anatomic structures surrounding the ankle is imperative. The most common of causes have been presented. The addition of provocative testing and radiographic examinations can aid in elucidating the pathology. After treatment of the injury, attention to training technique, shoe and insert usage as well as individual gait abnormalities are integrated into global patient education to decrease the incidence of injury recurrence

    Reliability and validity of the American Orthopaedic Foot and Ankle Society clinical eating scales: A pilot study for the hallux and lesser toes

    No full text
    Background: The use of clinical outcomes instruments is essential for the effective interpretation of individual patient progress as well as the comparison of treatment groups. An outcomes instrument must be reliable and valid to obtain any meaningful data. The purpose of the present study was to examine the reliability and validity of the American Orthopaedic Foot and Ankle Society (AOFAS) clinical rating scale for the hallux metatarsophalangeal- interphalangeal and lesser toes metatarsoplialangeal-interphalangeal joints. Methods: Eleven patients (one man, 10 women) with an average age of 54 (range 40 to 72) years and with classic rheumatoid arthritis not currently treated for foot complaints were enrolled in the present study. The average duration of rheumatoid arthritis was 14 years. Each patient completed a set of two outcomes instruments and had & physical examination by a single clinician at the initial visit and returned at 1 week for completion of the same scales and examination. The outcomes scales used were the AOFAS clinical rating scale for the hallux, the AOFAS clinical rating scale for the lesser toes, and the previously validated Foot Function Index (FFI). Test-retest reliability was evaluated using intraclass correlation coefficients between week 1 and week 2 for the summary scores as well as for the sebscales of pain and activity. Consistency between the two instruments was evaluated with Pearson correlation coefficients. Results: The AOFAS clinical rating scale for the hallux and lesser toes is repeatable between 1-week trials (ICC 0.95; p \u3c 0.05; ICC 0.80; p \u3c 0.05, respectively). Moderately strong correlations were found between the mean values for the AOFAS hallux and FFI (r = -0.81;p \u3c 0.05). Weaker correlations were seen between the mean vataes for the AOFAS lesser toes and FFI scales (r = -0.69;p \u3c 0.05). Conclusions: The faallux sabscale for pain correlates strongly with the FFI sabscale for pain, suggesting high content validity (r = -0.94;p \u3c 0.001). Ceiling effects were seen with the AOFAS lesser toe subscale for activity, limiting its usefulness in a general patient population. The AOFAS lesser toe sabscale for pain and the AOFAS hallux subscale for activity correlated weakly with the FFI values (r = -0.31;r = -0.37;p \u3e 0.05, respectively). Conclusions: Although the AOFAS hallux and lesser toe scales were found to be reliable in a rheumatoid patient population, their validity remains in question. These findings must be confirmed with larger subject numbers, with the inclusion of symptomatic patients before recommended routine use of the hallux clinical rating and lesser toe clinical rating scales.

    Current concepts review: Isolated gastrocnemius contracture and gastrocnemius recession

    No full text
    Recent literature has demonstrated an increased awareness of the role of an IGC in patients with foot and ankle symptoms and disorders. However, the contribution of an IGC to the pathology and natural history of these foot and ankle disorders is not known. Initial investigations of gastrocnemius recession procedures for a variety of pathologies suggest improvements in dorsiflexion range of motion, pain, and patient satisfaction. Functional outcomes, however, are less clear. Whether prospective or retrospective in design, comparison of outcomes among current investigations is difficult because of the small subject numbers and limited use of validated functional outcomes. Although further investigations are necessary, early reports note encouraging results for pain relief and increased motion for the gastrocnemius procedure used in isolation for plantar fasciitis, Achilles tendinopathy, metatarsalgia, and forefoot ulcerations.

    No full text
    Ā© 2019 European Foot and Ankle Society Background: Prospective studies to guide the application of a gastrocnemius recession for Achilles tendinopathy are limited. Our aim was to prospectively evaluate patient reported outcomes and muscle performance. Methods: Patients with unilateral recalcitrant Achilles tendinopathy who received an isolated gastrocnemius recession (n = 8) and a healthy control group (n = 8) were included. Patient reported outcomes, ankle power during walking and stair ascent, and the heel rise limb symmetry index (total work) were collected. Results: Improvements in pain and self-reported function were observed (six months and two years). Sport participation scores reached 92% by two years. Patients demonstrated lower ankle power during stair ascent and decreased limb symmetry during heel rise six months following treatment (p ā‰¤ .02). Conclusions: Study findings regarding long-term improvements in patient pain, self-reported function and sport participation, and early preservation of ankle function during walking, can help refine patient selection, anticipated outcomes, and rehabilitation strategies

    Background: A recent study found nonweightbearing stretching exercises specific to the plantar fascia to be superior to the standard program of weightbearing Achilles tendon-stretching exercises in patients with chronic plantar fasciitis. The present study used a cadaver model to demonstrate the influence of foot and ankle position on stretching of the plantar fascia. Methods: Twelve fresh-frozen lower-leg specimens were tested in 15 different configurations representing various combinations of ankle and metatarsophalangeal (MTP) joint dorsiflexion, midtarsal transverse plane abduction and adduction, and forefoot varus and valgus. Measurements were recorded by a differential variable reluctance transducer (DVRT) implanted into the medial band of the plantar fascia, and primary measurement was a percent deformation of the plantar fascia (stretch) with respect to a reference position (90 degrees ankle dorsiflexion, 0 degrees midtarsal and forefoot orientation, and 0 degrees MTP dorsiflexion). Results: Ankle and MTP joint dorsiflexion produced a significant increase (14.91%) in stretch compared to the position of either ankle dorsiflexion alone (9.31 % increase, p \u3c 0.001) or MTP dorsiflexion alone (7.33% increase, p \u3c 0.01). There was no significant increase in stretch with positions of abduction or varus (2.49%, p = 0.27 and 0.55%, p = 0.79). Conclusion: This study provides a mechanical explanation for enhanced outcomes in recent clinical trials using plantar fascia tissue-specific stretching exercises and lends support to the use of ankle and MTP joint dorsiflexion when employing stretching protocols for nonoperative treatment in patients with chronic proximal plantar fasciitis.
