Is the EQ-5D-5L a responsive test to evaluate results in elective foot and ankle surgery?

PURPOSE: To analyze the responsiveness and the minimally clinical important change (MCIC) of the EuroQol (EQ) 5D-5 L score in patients that had undergone foot/ankle surgery. METHODS: Patients that underwent elective foot/ankle surgery from January 2019 to December 2020 were included. They were assessed with the EQ-5D-5L, visual analogue pain scale and Manchester Oxford Foot Questionnaire (MOXFQ) preoperatively and 1 year postoperatively. The pre-post differences of all variables, Effect Size (ES) and MCIC were analyzed. RESULTS: 167 patients. All variables showed a significant pre-post improvement. The ES for EQ-index and EQ-VAS were 0.61 and 0.33 respectively. MCIC for EQ-index was 0.17 and EQ-VAS was 8.54. MOXFQ index ES was 1.46 and the MCIC was 23.8. VAS decreased from 59.4 to 26.62. CONCLUSION: The EQ-5D-5L is a sensitive test to detect changes after elective foot and ankle surgery with good responsiveness relative to the ES values in the EQ-index. LEVEL OF EVIDENCE: II.

Halving the usage of rigid-soled postoperative shoes does not affect outcomes in forefoot reconstruction surgery.

BACKGROUND: Postoperative shoes are commonly used after forefoot surgery. This study's aim was to demonstrate that reducing rigid-soled shoe time to 3 weeks neither compromises functional outcomes nor does it produce complications. METHODS: Prospective cohort study: 6 weeks versus 3 weeks of rigid postoperative shoe (100 and 96 patients respectively), after forefoot surgery with stable osteotomies. Manchester-Oxford Foot Questionnaire (MOXFQ) and pain Visual Analog Scale (VAS) were studied preoperative and one year postoperative. Radiological angles were also assessed after removing the rigid shoe and at 6 months. RESULTS: The MOXFQ index and pain VAS depicted similar results in each group (group A: 29.8 and 25.7; group B: 32.7 and 23.7) with no differences between them (p = .43 Vs. p = .58). Moreover, no differences were reported in their differential angles (HV differential-angle p = .44, IM differential-angle p = .18) or in their complication rate. CONCLUSION: In forefoot surgery with stable osteotomies, shortening the postoperative shoe time to 3 weeks, neither impairs clinical results nor the initial correction angle.

Outcome Assessment Performance of the SF-36, Manchester-Oxford Foot Questionnaire and AOFAS in Forefoot Reconstruction Surgery.

The purpose of this study was to investigate the measurement properties of the Short Form 36 (SF-36) to detect real change after forefoot reconstruction surgery. Responsiveness and minimally important change estimates were compared with those from the Manchester-Oxford Foot Questionnaire (MOXFQ) and the American Orthopaedic Foot and Ankle Society (AOFAS) measures. Eighty-three patients awaiting surgery were recruited. Patients completed pre- and 12 months postoperative the SF-36 and the MOXFQ. A surgeon assessed the AOFAS scores. The responsiveness to change was determined using the effect size (ES), the minimal detectable change (MDC) and the minimal clinically important change. Two subscales of the SF-36 demonstrated significant improvement, bodily pain (BP) and mental health. Only the BP domain appeared the most responsive with an ES of 0.73. All domains of the MOXFQ and AOFAS produced much larger effect sizes (ES > 1.5). MDC values for the majority of the SF-36 domains fell within measurement error except for the BP domain. Fewer patients showed significant improvement when compared with the MOXFQ pain domain. In conclusion, the SF-36 measuring tool proved to be neither reliable nor responsive enough to detect real change after forefoot surgery. Though the BP domain appeared to be the most responsive, it failed to detect meaningful change when compared to the MOXFQ-Pain and the Visual Analogue Scale.

Proximal Medial Gastrocnemius Release Versus Open Plantar Fasciotomy for the Surgical Treatment in Recalcitrant Plantar Fasciitis.

BACKGROUND: Plantar fasciitis is a common cause of foot pain. If conservative treatment fails, there is no consensus as to the best surgical management for recalcitrant plantar fasciitis (RPF). The aim of this study was to compare the results obtained from proximal medial gastrocnemius release (PMGR) with those obtained from open plantar fasciotomy (OPF) in terms of pain, satisfaction, health-related quality of life, and American Orthopaedic Foot & Ankle Society (AOFAS) score. METHODS: This is a prospective randomized trial conducted between 2012 and 2016. Patients with RPF for at least 9 months were included. Diagnosis was clinically made. The exclusion criteria were neuropathic heel pain; a history of previous foot fracture, surgery, or deformity; rheumatoid arthritis; or the need for long-term analgesic administration. After ruling out other conditions with magnetic resonance or ultrasound imaging, patients were randomized to be operated on with OPF or PMGR independently of the Silfverskjold test. Follow-up was carried out for up to 1 year. The AOFAS, visual analog scale (VAS) for pain, SF-36, and Likert scale for satisfaction were used to evaluate the results obtained. The analysis was done with 21 patients in the OPF group and 15 in the PMGR group. The demographic data (age, sex, body mass index, duration of symptoms, and positivity to the Silfverskjold test) of the groups were comparable. RESULTS: No differences were found in terms of the AOFAS (P = .24), VAS (P = .14), or any item of the SF-36. Satisfaction was very good in 85.8% of the PMGR group and 89.5% of the OPF group (P = .27). Faster recovery was observed in the PMGR group. CONCLUSION: OPF and PMGR provided good results for patients with RPF. Neither was superior to the other relative to pain, AOFAS score, satisfaction, or the SF-36. We recommend PMGR as the first option in RPF surgical management in order to avoid potential biomechanical complications related to OPF. LEVEL OF EVIDENCE: Level I, therapeutic randomized controlled trial.

Foot and ankle infections: Debridement, early fixation and rifampicin provide earlier recovery of function and quality of life.

BACKGROUND: Infection after foot and ankle fractures is a major concern for orthopedic surgeons. It is widely believed that final osteosynthesis should be delayed until the infection is cured. However, there is no literature that supports this practice. In addition, the delay impairs patient function and quality of life (QoL). METHODS: In the present study, four cases of ankle infection treated with aggressive debridement, early fixation and antibiofilm antibiotics are described. It is thought that, like other implant related infections, ankle infections can be rapidly treated with the definitive fixation and by curing the infection to make for a fast recovery of QoL and function. RESULTS: The infections were caused by MSSA and Pseudomonas aeruginosa in case 1, MSSA in case 2 and MRSA as well as K. pneumonia in case 3. Case 4 was a culture negative infection. They were susceptible to antibiofilm antibiotics (the gram-negative bacilli susceptible to ciprofloxacin and the gram-positive cocci susceptible to rifampicin). Cases 1, 3 and 4 were treated with a tibio-talo-calcaneal arthrodesis and case 2 was treated with a de-rotational fibular osteotomy and a medial closing wedge supramalleolar osteotomy. All cases improved at a median time of 4 weeks in terms of quality of life (SF-36) and function (AOFAS). At 2-years follow-up, no recurrence of infection was observed in any of the cases. All the cases achieved fusion or osteotomy healing at final follow-up. CONCLUSIONS: Early fixation after debridement combined with antibiofilm antibiotics can be performed in foot and ankle inflections to provide early recovery of QoL and function in patients.

Relationship of Plantar Fascia Thickness and Preoperative Pain, Function, and Quality of Life in Recalcitrant Plantar Fasciitis.

BACKGROUND: The measurement of plantar fascia thickness has been advocated as a diagnostic and prognostic instrument in patients with plantar fasciitis, but there are no data relative to it in recalcitrant plantar fasciitis. The aim of the study is to evaluate the correlation between plantar fascia thickness and pain, functional score, and health perception in patients with this condition. METHODS: Thirty-eight feet were studied with ultrasound and magnetic resonance imaging to measure plantar fascia thickness. The visual analogue scale (VAS), American Orthopaedic Foot & Ankle Society Hindfoot Score (AOFAS), and SF-36 were then recorded for each patient. The relationship between the fascia and these scores was analyzed to evaluate the correlation of thickness with pain, functional level, and health perception of patients. RESULTS: In patients with recalcitrant plantar fasciitis, plantar fascia thickness did not correlate with pain (VAS), AOFAS, or any item of the SF-36. CONCLUSION: The thickness of the plantar fascia in patients with recalcitrant plantar fasciitis did not correlate with its clinical impact, and thus, we believe it should not be used in treatment planning. LEVEL OF EVIDENCE: Level IV, case series.

Corticosteroid Injection for the Treatment of Morton's Neuroma: A Prospective, Double-Blinded, Randomized, Placebo-Controlled Trial.

BACKGROUND: The effectiveness of corticosteroid injection for the treatment of Morton's neuroma is unclear. In addition, most of the studies related to it are case-control or retrospective case series. The purpose of this study was to compare the effectiveness between corticosteroid injection associated with local anesthetic and local anesthetic alone (placebo control group) for the treatment of Morton's neuroma. METHODS: Forty-one patients with a diagnosis of Morton's neuroma were randomized to receive 3 injections of either a corticosteroid plus a local anesthetic or a local anesthetic alone. The patients and the researcher who collected data were blinded to the treatment groups. The visual analog scale for pain and the American Orthopaedic Foot & Ankle Score (metatarsophalangeal/interphalangeal score) were obtained at baseline, after each injection, and at 3 and 6 months after the last injection. RESULTS: There were no significant between-group differences in terms of pain and function improvement at 3 and 6 months after treatment completion in comparison with baseline values. At the end of the study, 17 (48.5%) patients requested surgical excision of the neuroma: 7 (44%) in the experimental group and 10 (53%) in the control group ( P = 1.0). CONCLUSION: The injection of a corticosteroid plus a local anesthetic was not superior to a local anesthetic alone in terms of pain and function improvement in patients with Morton's neuroma. LEVEL OF EVIDENCE: Level I, randomized controlled trial.

Influence of Hindfoot Malalignment on Hallux Valgus Operative Outcomes.

BACKGROUND: Hindfoot deformity has been described as a risk factor for poor hallux valgus (HV) surgery outcomes. However, there has been no study that demonstrates it. The purpose of this investigation was to evaluate the influence of hindfoot misalignment in HV surgery results. METHODS: All patients operated on for HV during 2010 and 2011 at 3 university hospitals were included. The preoperative and 2-year postoperative radiologic data included the HV and the intermetatarsal (IM) angles, the naviculocuboid overlap (NC), the talonavicular coverage (TN) angle, the talus-first metatarsal (T-1MT) angle, as well as the calcaneal pitch (CP) angle. Additionally, the Short Form-36 questionnaire version 2.0 (SF-36) and the American Orthopaedic Foot & Ankle Society (AOFAS) score, satisfaction and recurrence were also analyzed. A total of 207 met the inclusion criteria. There were 26 patients (12.6%) who could not be assessed at the 2-year follow-up. Patients were allocated to a varus, normal, or a valgus hindfoot tertile using the values for the CP, NC, TN, and T-1MT angles. RESULTS: No significant differences (P > .05) were found between the groups when the HV or IM angles, AOFAS, SF-36 Mental Composite Scale, SF-36 Physical Composite Scale, or satisfaction were compared. Similarly, no significant and strong correlations were observed (P > .05, ρ < 0.3) between any of the mentioned hindfoot measures and the outcomes scales. CONCLUSION: No influence of hindfoot misalignment on HV surgery outcomes was found in the present study in terms of correction, pain, function, satisfaction, or quality of life. Patients with hindfoot misalignment did not obtain worse outcomes in HV surgery. LEVEL OF EVIDENCE: Level II, prognostic, comparative study.

Prospective comparative study between two different fixation techniques in meniscal allograft transplantation.

PURPOSE: To compare the functional and radiographic results between two different horn fixation techniques for meniscal allograft transplant. METHODS: This is a prospective study of 88 meniscal allograft transplants with a mean 5-year follow-up. Forty transplants were performed on the medial compartment and 48 on the lateral compartment. The same surgeon performed all surgeries. Thirty-three grafts were fixed only with sutures (Group A) and 55 only with bony fixation (Group B). Both groups were comparable in terms of age, laterality, time since meniscectomy and preoperative functional and radiographic status. Functional assessment was done with Lysholm and Tegner scores and the Visual Analogical Scale for pain. Joint space narrowing was evaluated in the Rosenberg view. RESULTS: There was a significant improvement in Lysholm, Tegner and VAS scores without differences between Group A and Group B (n.s.). Radiographic evaluation did not show any joint space narrowing (n.s.). No differences in the comparison of all the variables of the two compartments were found. There were complications in 33.3 % of patients in Group A that including 7 graft tears (21.4 %) and in which there was an allograft failure rate of 9 %. Group B showed complications in 16.4 % of the patients and included 4 graft tears (7.3 %, n.s.) with an allograft failure rate of 3.6 %. CONCLUSIONS: Meniscal allograft transplantation with either technique provided good functional and radiographic results at mid-term follow-up. Both graft fixation methods showed no differences relative to functional and radiographic results. There was a considerably higher rate of complications in transplantations performed with the only-suture technique than those with bony fixation, although the difference was not statistically significant with the numbers available. The results suggest that similar functional results should be expected whether the meniscal graft includes bone plugs or not. However, graft tears seem to happen more frequently if the MAT is performed without bony fixation. LEVEL OF EVIDENCE: Prospective comparative study, Level II.

Suture-only fixation technique leads to a higher degree of extrusion than bony fixation in meniscal allograft transplantation.

BACKGROUND: Most of the published series of transplanted menisci have consistently shown some degree of allograft extrusion. The speculation is that this meniscal extrusion may be caused by the soft tissue technique used to fix the allograft. HYPOTHESIS: The percentage of extruded meniscal graft would be higher if the allograft were only fixed with sutures rather than with associated bony fixation. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: We performed a prospective series of 88 meniscal allograft transplantations. Thirty-three of the grafts were fixed with the suture-only technique (group A). The remaining 55 cases were performed with the bone plug method (group B). All patients were studied with magnetic resonance imaging (MRI) at a minimum 3 years' follow-up to determine the degree of meniscal extrusion. The time between surgery and MRI evaluation was 40 months (range, 36-48 months) in both groups. Meniscal extrusion was measured on coronal MRI. The percentage of the meniscal body width that was extruded was calculated. The average percentage of extrusion for each group was compared. The Lysholm score was analyzed in relation to the fixation method and degree of meniscal extrusion. Tears of the allograft that required surgical intervention were also reported. RESULTS: The average percentage of meniscal tissue extruded in group A was 36.3% ± 13.7% without differences between the medial (35.9% ± 18.1%) and lateral (38.3% ± 14.4%) compartments (P = .84). Group B had a mean 28.13% ± 12.2% of the meniscal body extruded without differences between the medial (25.8% ± 16.2%) and lateral (30.14% ± 13.5%) compartments. A higher percentage of extruded meniscal tissue was found in group A than in group B (P < .001). No association between the degree of meniscal extrusion and the functional score was observed (P = .4). Graft tears were observed in 21.4% of the cases in group A and in 7.3% of the cases in group B (P = .09). CONCLUSION: A meniscal allograft fixed with the suture-only technique showed a significantly higher degree of extruded meniscal body than that fixed with the bony fixation method, with no influence on the functional outcome. There was also a considerably higher rate of graft tears observed in those menisci fixed only with sutures, although this difference was not statistically significant with the numbers available.

Meniscal allograft transplantation without bone blocks: a 5- to 8-year follow-up of 33 patients.

PURPOSE: The purpose of this study was to evaluate the functional and radiographic results on a midterm basis, as well as complications, in an initial series of meniscal allograft transplantations performed with suture fixation without any bone block. METHODS: A series of 33 meniscal allograft transplantations were performed at our institution from January 2001 to October 2003. Inclusion criteria were patients with compartmental joint line pain due to a previous meniscectomy. There were 24 men and 9 women with a mean age of 38.8 years (range, 21 to 54 years). The functional outcomes were evaluated by use of Lysholm and Tegner scores at a mean and minimum follow-up of 6.5 years and 5 years, respectively. A visual analog scale for pain was also used. Radiographic assessment included joint space narrowing on the Rosenberg view and magnetic resonance imaging evaluation. RESULTS: The Lysholm and Tegner scores significantly improved from 65.4 to 88.6 (P < .001) and from 3.1 to 5.5 (P < .001), respectively, after surgery. The visual analog scale score significantly dropped from 6.4 to 1.5 (P < .001). The radiographic evaluation did not show any joint space narrowing (P = .38). Meniscal extrusion was a constant finding, averaging 36.3% of total meniscal size. According to the Van Arkel criteria, the survival rate was 87.8% at 6.5 years. The rate of complications was 33%. CONCLUSIONS: This study suggests that this procedure provides significant pain relief and functional improvement in selected symptomatic individuals on a midterm basis. However, there was a high rate of complications (33%) and revision surgery. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
