Retrospective Evaluation of Ultrasound Guided Percutaneous Plantar Fasciotomy With and Without Platelet Rich Plasma.

Plantar fasciitis is one of the most common foot conditions presenting to a foot and ankle specialist. Surgical treatment outcomes following plantar fasciotomy vary but short-term studies have reported excellent early pain relief and significant improvements in symptoms. This study evaluates patient reported pain scores collected pre- and post-op for patients who underwent percutaneous ultrasonic microtenotomy (PUT) plantar fasciotomy with PRP injection vs without the use of PRP. We compared pain visual analog scale (VAS) scores, for patients treated surgically by Orthopedic Surgery department of foot and ankle faculty members between December 2007 and December 2022. A total of 30 patients were identified that met inclusion and exclusion criteria. Our results showed that there was a significant decrease in pain VAS scores from pre-op visit (at least 1 month prior to operation) to post-op visit (at least 1 month following operation) for both groups, with a paired t test (p value <.0001). However, patients who received PRP had a statistically significant decrease in pain level compared to the group who did not receive PRP. Statistical analysis completed with a 2-sample t test (p-value <.0325). Our results found the mean time between the initial pre-op visit and last post-op follow-up visit was 19 months. The mean for time following surgical intervention was 10 months. The findings of our study suggest that the dual use of PUT and PRP to treat plantar fasciitis, could potentially lead to an improvement in pain reduction and longevity of pain relief.

Reliability of Ultrasound Measurement of Plantar Fascia Thickness: A Systematic Review.

BACKGROUND: Because ultrasound measurement of plantar fascia thickness is widely used in the diagnosis and evaluation of plantar fasciitis, it is important to understand and minimize the errors that occur with this measurement. The aim of this systematic review was to identify and synthesize studies reporting on intrarater and interrater reliability of ultrasound measurement of plantar fascia thickness. METHODS: After comprehensive searches in the MEDLINE, Embase, and Cochrane Library databases, 11 studies involving 238 healthy participants and 68 patients with pathologic foot disorders were included. RESULTS: Seven of 11 studies revealed a low risk of bias. Most of the studies reported good to excellent intrarater and interrater reliability for ultrasound measurement of plantar fascia thickness (intrarater intraclass correlation coefficient [ICC], 0.77-0.98; interrater ICC, 0.76-0.98). In addition, two studies on intrarater reliability and one study on interrater reliability showed moderate reliability (ICCs, 0.65, 0.67, and 0.59, respectively). Overall, the standard error of measurement was less than 5% and did not exceed 7%. CONCLUSIONS: The findings of this review suggest that ultrasound measurement of plantar fascia thickness is reliable in terms of both relative and absolute reliability. Reliability can be optimized by using the average of multiple measurements and an experienced operator.

Does the slope and length of the plantar calcaneal spur affect the clinic?

Since some of the patients with plantar calcaneal spur (PCS) do not have pain, we aimed to investigate the effect of the slope and length of the spur on this situation. The length and slope of PCS were measured by examining the radiological images of 50 patients in this prospective study. VAS, AOFAS and FFI scores of the patients were determined. Patients were divided into groups according to PCS length and slope. According to the slope of the spur, the mean AOFAS, FFI and VAS scores were, respectively; 94, 38, 1.3 in below 20 degrees; 80.1, 86.8, 4.8 in 20-30 degrees; and 70.1, 106, 6.7 in above 30 degrees. According to the length of the spur, the mean AOFAS, FFI and VAS scores were respectively; 84.9, 68.2, 3.7 in those with length 0-5 mm; 81.1, 81.7, 4.5 in those with a length of 5-10 mm; and 71.7, 102.5, 6.4 in those with a length of >10 mm. A significant correlation was found between the angle and length of the PCS with the values of VAS, AOFAS and FFI (p<0.05). We observed that PCSs with a slope of less than 30 degrees and shorter than 10 mm do not create a serious clinical picture. If there is severe pain and functional impairment in individuals with this characteristic spur, investigation of other possible causes of heel pain must be considered.

Ultrasonography-guided Intervention in the Achilles Tendon and Plantar Fascia.

Tendinopathy is very common in the foot and ankle. Achilles tendinopathy is a painful overuse injury that often occurs in athletes, especially those who participate in running and jumping sports. Plantar fasciitis is the most frequent cause of plantar pain in the adult heel. Initial treatment of these conditions is conservative. However, in some cases symptoms only improve slowly, and many cases are intractable. When conservative management fails, ultrasonography guided injections are indicated. We discuss the main interventions performed in the foot and ankle for Achilles tendinopathy, retrocalcaneal bursitis, and plantar fasciitis. We describe the different agents that can be used and the various ultrasonography-guided procedures that offer technical and practical information to improve daily clinical practice.

Is there an association between plantar fasciitis and knee osteoarthritis?

BACKGROUND: Knee osteoarthritis (OA) and plantar fasciitis share similar risk factors including ageing, occupation, obesity, and inappropriate shoe wear. However, the association between knee OA and heel pain caused by plantar fasciitis has received limited attention to date. AIM: We aimed to assess the prevalence of plantar fasciitis using ultrasound in patients with knee OA and to identify factors associated with plantar fasciitis in these patients. PATIENTS AND METHODS: We conducted a cross-sectional study including patients with Knee OA, fulfiling the European League Against Rheumatism criteria. The Western Ontario and McMaster Universities Osteoarthritis (WOMAC) and the Lequesne indexes were used to evaluate pain and function of the knees. The Manchester Foot Pain and Disability Index (MFPDI) was used to estimate foot pain and disability. Each patient underwent a physical examination, plain radiographs of the knees and the heels, and an ultrasound examination of both heels to find signs of plantar fasciitis. Statistical analysis was performed using SPSS. RESULTS: We included 40 knee OA patients, with a mean age of 59.85 ± 9.65 years [32-74] and a male-to-female ratio of 0.17. The mean WOMAC was 34.03 ± 19.9 [4-75]. The mean Lequesne for knees was 9.62 ± 4.57 [3-16.5]. Among our patients, 52% (n = 21) experienced heel pain. The heel pain was severe in 19% (n = 4). The mean MFPDI was 4.67 ± 4.16 [0-8]. Limited ankle dorsiflexion and plantar flexion were noted in 47% of patients (n = 17) each. High and low arch deformities were seen in 23% (n = 9) and 40% (n = 16) of patients. Ultrasound revealed a thickened plantar fascia in 62% (n = 25). An abnormal hypoechoic plantar fascia was noted in 47% (n = 19), with the loss of normal fibrillar architecture in 12 cases (30%). No Doppler signal was exhibited. Patients with plantar fasciitis had significantly limited dorsiflexion (n = 2 (13%) versus n = 15 (60%), p = 0.004) and plantar flexion (n = 3 (20%) versus n = 14 (56%), p = 0.026). The range of supination was also less important in the plantar fasciitis group (17.73 ± 4.1 vs. 12.8 ± 6.46, p = 0.027). The low arch was statistically more present in patients with plantar fasciitis (G1: 36% [n = 9] vs. G0: 0% [n = 0], p = 0.015). However, the high arch deformity was statistically more present in patients without plantar fasciitis (G1: 28% [n = 7] vs. G0: 60% [n = 9], p = 0.046). Multivariate analysis showed that the risk factor for plantar fasciitis in knee OA patients was limited dorsiflexion (OR = 3.889, 95% CI [0.017-0.987], p = 0.049). CONCLUSION: In conclusion, our work showed that plantar fasciitis is frequent in knee OA patients, with reduced ankle dorsiflexion being the main risk factor for plantar fasciitis in these patients.

Effects of customized insoles with medial wedges on lower extremity kinematics and ultrasonographic findings in plantar fasciitis persons.

The customized insole is widely recommended as an effective intervention for pain reduction and foot function improvement in plantar fasciitis persons. However, it is unclear whether the additional correction of medial wedges could change the kinematics from the only insole. The objectives of this study were thus to compare customized insoles with and without medial wedges on lower extremity kinematics during gait and to determine the short-term effects of the customized insole with medial wedges on pain intensity, foot function, and ultrasonographic findings in plantar fasciitis persons. A within-subject, randomized, crossover design within motion analysis research laboratory was conducted among 35 persons with plantar fasciitis. Main outcome measures included joint motions of the lower extremity and multi-segment foot, pain intensity, foot function, and ultrasonographic findings. The customized insole with medial wedges produced less knee motion in the transverse plane and hallux motion in all planes during the propulsive phase than that without medial wedges (all p < 0.05). After the 3-month follow-up, the insoles with medial wedges decreased pain intensity and increased foot function. Abnormal ultrasonographic findings also decreased significantly after the 3-month treatment of insoles with medial wedges. Customized insoles with medial wedges seem superior to those without medial wedges on both multi-segment foot motion and knee motion during propulsion. Positive outcomes from this study supported the use of customized insoles with medial wedges as an effective conservative treatment in patients with plantar fasciitis.Trial registration: TCTR20210928006 (28/09/2021).

Effect of radial shock wave and ultrasound therapy combined with traditional physical therapy exercises on foot function and dorsiflexion range in plantar fasciitis: a prospective randomized clinical trial.

OBJECTIVE: This study aimed to assess the effect of radial shock wave and ultrasound therapy combined with traditional physical therapy on foot function and range of motion in chronic plantar fasciitis. PATIENTS AND METHODS: Sixty-nine participants with chronic plantar fasciitis (25-56 years) were allocated randomly into three groups. Group (A) received ultrasound (US) therapy plus conventional physical therapy exercises (in the form of stretching, strengthening exercise, and deep friction massage), Group (B) received a radial shock wave (RSW) therapy plus conventional physical therapy exercises, and Group (C) received a combination of both RSW and US therapy in addition to conventional physical therapy exercises, with 3 sessions per week for US therapy and one session for RSW therapy, in addition to 45 minutes of exercises for all groups for 4 consecutive weeks. Foot function was assessed using the foot function index (FFI), and ankle dorsiflexion range of motion was measured using the Baseline® bubble inclinometer at baseline and 4 weeks following treatment. RESULTS: ANOVA revealed significant differences (p<0.05) in the measured outcomes among the groups after treatment. Tukey's honest significant difference post-hoc test demonstrated a highly statistically significant (p<0.001) improvement in the assessed outcomes of group C in the post-intervention settings when compared to the other groups. After 4 weeks of intervention, the mean (SD) of FFI in groups A, B, and C were (64.54±4.91, 61.93±4.17, and 45.16±4.57) respectively, and the active range of motion (ROM) of the ankle dorsiflexion were (35.27±3.22, 36.59±2.91, and 41.85±3.04) respectively. CONCLUSIONS: The addition of RSW to US with the conventional physical therapy program improved foot function and ankle dorsiflexion range of motion significantly for patients with chronic plantar fasciitis.

Do the presence, size, and shape of plantar calcaneal spurs have any significance in terms of pain and treatment outcomes in patients with plantar fasciitis?

BACKGROUND: : The purpose of this study was to determine the effect of the presence, size, or type of calcaneal spurs on pain or the outcomes of extracorporeal shock wave therapy (ESWT) therapy in patients with plantar fasciitis. METHODS: Seventy-four patients with unilateral plantar fasciitis who had no pain in the contralateral foot, either currently or in the past, were included in the study. The length, base width, type, and presence of plantar calcaneal spurs in both heels of the patients were determined using radiography. A total of five sessions of ESWT (3 bar, 2000 shocks/session, 12 Hz frequency) with an interval of 3 days were performed on the painful sides of the patients. Symptom duration and numerical rating scale (NRS) scores were recorded pretreatment and 1 week and 12 weeks after treatment. RESULTS: : Spurs were detected in 85.1% of painful feet and 71.6% of painless feet, this difference was statistically significant (p = 0.046). There was no significant correlation between the type of the spurs and whether the foot was painful. Patients with spur sizes of >5 mm or with horizontal and hooked spurs had a higher NRS decrease than patients with spur sizes of ≤5 mm or with a vertical spur. Symptom duration, spur length, and base width were found to be correlated with pretreatment NRS scores. DISCUSSION: The presence and size of calcaneal spurs are associated with pain. However, it should be kept in mind that a high rate of spurs can also be found in painless feet, so spur is not the only factor that causes pain. Patients with a spur size of ≤5 mm or a vertical spur have less pain relief with ESWT.

Anatomical features of plantar fasciitis in various age cohorts: Based on magnetic resonance imaging.

BACKGROUND: Due to the lack of further studies on the influence of age factors on plantar fasciitis, this study evaluates the characteristic observation points of magnetic resonance imaging in various age cohorts of patients with plantar fasciitis to help diagnosis. METHODS: A retrospective analysis of 160 cases of plantar fasciitis patients and normal subjects (who have the disease unrelated to plantar fasciitis) who have undergone an MRI examination in our institution. The two groups were separately divided into young adult subjects (36 to 44 years old), middle age adult subjects (45 to 59 years old), and older adult subjects (60 to 79 years old). Data was gathered regarding plantar fascia thickness, the coronal length of the plantar fascia at the calcaneal origin, the signal intensity of plantar fascia and surrounding structures, and the presence or absence of plantar calcaneal spurs, all of which were assessed objectively by the investigators. RESULTS: There were statistical differences in the thickness of plantar fascia between two groups of three age cohorts (Older adult patients: 0.59 ± 0.09 cm; Middle age adult patients: 0.49 ± 0.09 cm; Young adult patients: 0.47 ± 0.05 cm) (all p < 0.001). In addition, there were also statistical differences in the high signal intensity changes of the plantar fascia and surrounding soft tissues between two groups of three age cohorts (all p < 0.001). In older adult plantar fasciitis patients, with regard to plantar calcaneal spur discovery, there was a statistical difference between the two groups (Chi-square = 12.799. df = 1. p < 0.001). CONCLUSION: In plantar fasciitis cases where a diagnosis is difficult, abnormalities in the soft tissue surrounding the plantar fascia in patients of low age are noteworthy. In older adult patients, the discovery of plantar calcaneal spurs with abnormal thickening of plantar fascia deserves attention, and abnormal MRI findings are more manifest. But the final diagnosis should be based on the medical history. LEVEL OF EVIDENCE: Level 3.

Shear-wave elastography of the plantar fascia: a systematic review and meta-analysis.

PURPOSE: To assess the efficacy of shear-wave elastography (SWE) of the plantar fascia (PF) in identifying plantar fasciitis. METHODS: A literature search was conducted on the PubMed and Medline databases for articles published up to August 2022. The Newcastle-Ottawa scale was used to assess the risk of bias. We included original research studies in English dealing with the evaluation of patients with plantar fasciitis by means of SWE and including shear modulus (KPa) and/or shear-wave velocity (m/s). We compared healthy and pathologic PF stiffness using the standardised mean difference (SMD) in a random-effects model (95% CI). RESULTS: Five studies were included with a total of 158 pathologic PFs and 134 healthy PFs. No significant publication bias was detected. Studies were highly heterogeneous (p < 0.00001; I2 = 97%). Pathologic PFs showed significantly lower stiffness, with an SMD of - 3.00 m/s (95% confidence interval: - 4.95 to - 1.06, p = 0.002), compared to healthy PF. CONCLUSION: Pathologic PFs present significantly lower stiffness than healthy PFs. However, the analysed studies are highly heterogeneous.

Effects of dry needling and stretching exercise versus stretching exercise only on pain intensity, function, and sonographic characteristics of plantar fascia in the subjects with plantar fasciitis: a parallel single-blinded randomized controlled trial.

OBJECTIVES: Plantar fasciitis is a common problem in the foot region which has negative considerable impact on foot function. METHODS: In this parallel blinded randomized controlled trial, a total of thirty-seven subjects with plantar fasciitis (forty feet) were enrolled randomly to either the control group (stretching exercise) or the experimental group (stretching exercise plus dry needling). All interventions lasted six weeks and both groups were followed for two weeks. Primary outcomes were first step pain, pain, and activity daily function subscales of the FAOS questionnaire and secondary outcomes were plantar fascia thickness, and echogenicity. RESULTS: The mixed model ANOVAs showed significant group × time interactions for all primary outcomes. In both groups, first step pain and both subscales of the FAOS questionnaire were improved compared to baseline measurements. There were considerable differences between the two groups and the experimental group experienced more improvements in primary outcomes compared to the control group. For secondary outcomes, plantar fascia thickness at insertion significantly decreased, and the echogenicity in the two regions significantly increased in the experimental group compared to the control group. CONCLUSION: These results suggest that the combination of dry needling and stretching exercises can be an effective conservative treatment for plantar fasciitis subjects.

Ultrasound-Guided Injection of Dextrose Versus Corticosteroid in Chronic Plantar Fasciitis Management: A Randomized, Double-Blind Clinical Trial.

DESIGN: Chronic plantar fasciitis (PF) is a common cause of chronic heel pain, with different conventional treatment options. In this randomized clinical trial, the effect of ultrasound-guided injection of dextrose versus corticosteroid in chronic PF was evaluated and compared. METHODS: A total of 44 patients suffering from chronic PF who visited the physical medicine and rehabilitation clinic were enrolled in the study. Two table-randomized groups were formed. They received an ultrasonography-guided, single injection of either 40 mg methylprednisolone or 20% dextrose. Numeric Rating Scale (NRS), Foot and Ankle Ability Measure questionnaire with 2 subscales, Activities of Daily Living (FAAM-A) and Sports (FAAM-S), along with ultrasonographic parameters were evaluated before and at 2 and 12 weeks after the injection. Results. A total of 40 participants completed the study. Both interventions significantly improved pain and function at 2 and 12 weeks postinjection. After 2 weeks, compared with the dextrose prolotherapy, the corticosteroid group had significantly lower daytime and morning NRS scores (2.55 vs 4.1, P = .012, and 2.75 vs 4.65, P = .004), higher FAAM-S (66.84 vs 54.19; P = .047), and lower plantar fascia thickness at insertion and 1 cm distal to the insertion zone (3.89 vs 4.29 mm, P = .004, and 3.13 vs 3.48 mm, P = .002), whereas FAAM-A was similar in both groups (P = .219). After 12 weeks, all study variables were statistically similar between corticosteroid and dextrose prolotherapy groups. No injection-related side effects were recorded in either group. CONCLUSION: Both methods are effective. Compared with dextrose prolotherapy, our results show that corticosteroid injection may have superior therapeutic effects early after injection, accompanied by a similar outcome at 12 weeks postinjection. LEVELS OF EVIDENCE: Level II.

Is 2D SWE sufficient as clinical diagnosis in patients with plantar fasciitis?

BACKGROUND: The use of shear wave elastography (SWE) seems to be an important imaging method in the diagnosis of plantar fasciitis (PF). PURPOSE: To compare patients diagnosed with PF with similar and young healthy control groups in terms of B-mode ultrasound (US) and SWE results and to evaluate the elasticity of the plantar fascia. MATERIAL AND METHODS: A total of 140 feet of 70 participants were evaluated, including 30 patients and 40 healthy individuals as the control. Clinical, B-mode US, and SWE evaluations were performed for each patient. In addition, American Orthopedic Foot and Ankle Score (AOFAS) was calculated to evaluate pain and foot function in both groups. RESULTS: Of the patients in the PF group, 40 (88%) were women and the healthy control groups had similar sex distributions (P = 0.23). The AOFAS score was lower in feet with PF compared to the other groups (P < 0.001). Of 30 patients with PF, 15 (50%) had bilateral PF and 15 (50%) unilateral PF. In addition, ≥4 mm thickness measurement, which was used as a diagnostic criterion for PF as a US finding, could be shown in 11 (73.3%) patients with unilateral PF and 6 (40%) patients with bilateral PF. CONCLUSION: In conclusion, the evaluation of the diagnosis of PF with clinical findings and regular follow-up of measurements with SWE can provide measurement results with higher sensitivity in the diagnosis of PF.

Effect of Age and BMI on Sonographic Findings of Plantar Fascia.

Biomechanical dysfunction of the foot is most common cause of plantar fascia disorder and obesity and increasing age are well-known risk factors. Due to being inexpensive and quick, ultrasound imaging techniques are considered the modality of choice to assess plantar fascia. The aim of this study was to investigate the effect of age and body mass index (BMI) on sonographic findings of plantar fascia in normal population. Ultrasonography was used to measure the plantar fascia thickness of 148 healthy adults (54 males, 36.5% and 94 females, 63.5%) during a period of one year. The age, BMI, and walking distance of each participant were recorded and statistically analyzed. The mean plantar fascia thicknesses at 0.5, 1.0, and 2.0 cm distal to the insertion of the plantar fascia were 1.76 ± 0.32 mm, 2.50 ± 0.50 mm and 2.11 ± 0.41 mm respectively. The mean plantar fascia thickness for individuals ≥45 years and BMI ≥25 were significantly higher (p < .001) compared to individuals <45 years and BMI <25. In a normal population, the thickness of the plantar fascia determined by ultrasound measurement was less than 3 mm. We recommend using the position 1.0 cm distal to the calcaneal insertion of the plantar fascia as the reference point for diagnosing plantar fasciitis. The thickness of plantar fascia was significantly increased with age and BMI whereas gender, walking activity, exercise and running did not seem to affect the plantar fascia thickness.

An assessment of plantar fascia with ultrasound findings in patients with plantar fasciitis: a systematic review.

INTRODUCTION: Plantar fasciitis (PFS) is described by an intense pain over medial tubercle of calcaneus, increased with the first step after waking up, after rest and during weightbearing activity. It is the most common cause of plantar heel pain in adults with the prevalence estimated 10% of the general population. Ultrasound imaging is commonly being used to measure the PF thickness, evaluate the efficacy of different treatments and a guide therapeutic technique in patients with PFS. The objective of this study was to systematically review the studies that were previously published to evaluate the role of ultrasound in the assessment of PF in patients with PFS. METHODS: A systematic search was carried out over the last 5 years from 2017 to 2022 on basis the following electronic databases: Science Direct, Scopus, Web of Science, Springer and PubMed. The keywords that used in the searching were: ultrasound, sonography, ultrasonography, plantar fasciitis, imaging of plantar fascia, physiotherapy of plantar fasciitis, interventional treatment of plantar fasciitis, randomized controlled trial of plantar fasciitis and interventional ultrasound. The review focused on the assessment of PF in patients with PFS underwent different interventions using B-mode, shear wave elastography (SWE) and color Doppler ultrasound. RESULTS: During the search process, 1661 were recorded using the proper keywords from 2017 to 2022 in which 666 original articles were found after removing the review and duplicated articles. Of these, thirty articles met the inclusion criteria and included in this review. The articles have assessed the PF in patients with PFS under different conditions using different ultrasound modes. Twenty-six articles evaluated the effectiveness of different treatment on PF in patients with PFS using different ultrasound modes. In 8 of 26 articles, the ultrasound was used as both an assessment tool of PF and guide therapeutic technique in patients with PFS. In 18 articles, the ultrasound was used as only assessment tool to identify the PF thickness and its observation changes in patients with PFS. Four articles compared the PF thickness and its intrafascial changes between patients with PFS and healthy subjects. CONCLUSION: The ultrasound can be a reliable tool in assessment the effect of different interventions on PF by evaluating its thickness, echogenicity and stiffness changes in patients with PFS. There were different methods and treatments were used among the studies.

Role of shear wave elastography in the diagnostic evaluation of plantar fasciitis: a prospective case-control study.

OBJECTIVES: To assess the advantage of the addition of shear wave elastography (SWE) to gray-scale sonography in the diagnosis of plantar fasciitis. METHODS: 30 subjects between 18-60 years of age with unilateral heel pain who were clinically suspected of having plantar fasciitis were included in this study. Their affected feet were taken as cases; while their contralateral feet served as controls. On gray-scale ultrasound, the thickness of plantar fascia, its echopattern, presence of hypoechoic areas, and perifasicular collections were recorded. SWE was done by placing seven ROIs within the plantar fascia; and the mean of their Young's modulus was taken in kPa. RESULTS: Plantar fascial thickening more than 4 mm had 70% sensitivity and 66.7% specificity, echopattern had 90% sensitivity and 96.7% specificity, hypoechoic areas had 80% sensitivity and 96.7% specificity, and perifascial edema had 26.7% sensitivity and 100% specificity for diagnosing plantar fasciitis. Using the ROC curve, the cut-off value of Young's modulus for the diagnosis of plantar fasciitis was found to be ≤ 99.286 kPa. This predicted plantar fasciitis with 97% sensitivity and 100% specificity. The primary diagnostic feature of ultrasound of plantar fascia thickness more than 4 mm detected 21 out of 30 cases of plantar fasciitis; whereas elastography detected an additional 8 cases which would have been missed on B-mode ultrasound alone. CONCLUSIONS: SWE is a useful supplement and improves the diagnostic accuracy of gray-scale ultrasound in plantar fasciitis.

Ultrasound-Guided Autologous Platelet-Rich Plasma Injections Versus Focal Ultrasound-Guided Extracorporeal Shockwave Therapy for Plantar Fasciitis in Athletes and Nonathletes: A Retrospective Comparative Study With Minimum 2-Year Follow-Up.

Plantar fasciitis is often cause of heel pain, especially in sporting-related activities. Different conservative measures for the management of plantar fasciitis were compared in several researches. The purpose of this retrospective study was to evaluate and compare clinical outcomes of chronic plantar fasciitis treated with ultrasound-guided platelet-rich plasma (PRP) and focal ultrasound-guided extracorporeal shockwave therapy (ESW). Secondarily, results on subpopulation of athletes were recorded. Fifty-five patients treated for plantar fasciitis were included, 24 among them were competitive or recreational athletes. Treatment outcomes were assessed using Visual Analog Scale and Foot Function Index before and after treatment. Time to return to sport among patients practicing sporting activities was recorded. Before treatment, no differences were observed between groups in terms of age, gender, body mass index, and months of follow up. From baseline to final follow-up assessment, significant improvement was observed in all the outcomes measures. The subgroup analysis showed no differences between patients stratified for type of treatment and sport/nonsport practitioners. The overall failure rate was higher, although not significant, in patients who underwent ESW therapy and they required a higher number of orthopedic visits. Among sports practitioners the mean time to return to sport (months) was faster in PRP group than ESW group (p = .044). PRP and ESW represent both reliable solutions for plantar fasciitis leading to good results in terms of patients' satisfaction, pain, and clinical outcomes. However, after treatment with PRP injections less recurrences in overall population and faster return to sporting activities in sports practitioners were observed.

INCIDENTAL INTRAOSSEOUS CALCANEAL LIPOMA IN A PATIENT SUFFERING FROM PLANTARFASZIITIS.

Intraosseous calcaneal lipoma is a rare benign bone tumor. The incidence of intraosseous lipoma involving the calcaneus has been noted to account for fewer than 8-15% of all intraosseous lipoma. The etiology of the lesion is unknown. A post-traumatic secondary bone reaction, healing bone infarct, and benign neoplasm have been discussed. The symptoms can be nonspecific, varying from dull, intermittent pain to activity-related plantar pain. This pain can predictably be misdiagnosed as plantar fasciitis. We present the case of a 49-year-old male patient suffering from plantar fasciitis for three months and incidental asymptomatic intraosseous calcaneal lipoma, which was diagnosed by x-ray and CT scan. As the patient was out of complaints, the typical CT findings we saw no indication for biopsy but recommended regular CT and MRI controls.;

Ultrasound-Guided Partial Plantar Fascia Release with the Use of a Fine Cutting Device for the Treatment of Persistent Plantar Fasciitis: A Case Series.

BACKGROUND: Plantar fasciitis is a common cause of musculoskeletal discomfort. Minimally invasive interventions are preferred as second-line treatments following failure of conservative management. We report on a novel technique of ultrasound-guided percutaneous release of the medial third of the plantar fascia with the use of a fine cutting device for the treatment of persistent plantar fasciitis. METHODS: This is a retrospective case series of all patients treated with the technique between 2013 and 2015. Patients had failed conservative management for a minimum of 6 months. The procedure was performed in an outpatient setting under local anesthesia. Under continuous ultrasound guidance, release of the medial third of the plantar fascia from the calcaneus was performed using an ophthalmic V-Lance knife through a medial stab wound entry point. RESULTS: Fifteen patients (six men and nine women) with an average age of 54.7 years were included. The mean (standard deviation [SD]) visual analogue scale score for pain improved significantly, from 66.0 (SD, 18.8) preoperatively to each consecutive follow-up point: 29.3 (SD, 25.2) at 2 weeks, 30.0 (SD, 27.8) at 4 weeks, and 34.0 (SD, 26.1) at 12 weeks (P < .001). The mild increase in visual analogue scale score between 4 and 12 weeks was statistically significant (P = .018). Average duration of required analgesia was 5.5 days and average time required to return to usual activities was 5.7 days. Two patients suffered with refractory neuropathic pain over the lateral border of the foot without any obvious abnormality. CONCLUSIONS: Ultrasound-guided percutaneous release with the use of a fine cutting device could be an alternative option for the treatment of persistent plantar fasciitis. The technique is not without complications, and a mild but statistically significant decline in pain levels from early to short term has been detected. Therefore, the long-term outcomes of this technique need to be investigated before we can advocate its routine use.

Age, Body Mass Index, and Spur Size Associated with Patients' Symptoms in Plantar Fasciitis.

Background: Plantar fasciitis is a common cause of heel pain affecting 10% of the general population. This study aimed to investigate the specific symptoms in patients with plantar fasciitis using the Foot and Ankle Outcome Score (FAOS) questionnaire and their relationship with demographic and radiographic factors. Methods: We retrospectively analyzed 73 consecutive patients (mean age, 53.8 ± 10.0 years; 20 men and 53 women) with plantar fasciitis who had visited our foot and ankle clinic and undergone weight-bearing foot X-ray examinations. Their demographic data, anteroposterior and lateral talo-first metatarsal angles, intermetatarsal and hallux valgus angles, and responses to the FAOS questionnaire were recorded. Results: The quality-of-life subscale showed the lowest score of all FAOS subscales. Age was significantly correlated with quality of life (r = 0.297, p = 0.011), and body mass index was correlated with the function in sports and recreational activities (r = -0.251, p = 0.032). Age and body mass index were statistically significantly correlated with calcaneal spur size (r = 0.274, p = 0.027 and r = 0.324, p = 0.008, respectively). The calcaneal spur size was significantly correlated with pain (r = -0.348, p = 0.004), function in daily living (r = -0.410, p = 0.001), and function in sports and recreational activities (r = -0.439, p < 0.001). Conclusions: Demographic factors were associated with specific symptoms in patients with plantar fasciitis. Calcaneal spur size was the only radiographic parameter correlated with symptoms. These findings help communicate with patients, set appropriate treatment goals, and evaluate treatment effectiveness.
