Published: October 2019

Category: Ankle Introduction/Purpose: The purpose of this study was to describe the mid to long-term clinical and radiological outcomes of an open fixation technique for large primary talar osteochondral defects (OCD): Lift, Drill, Fill and Fix (LDFF). Methods: Nineteen patients underwent an open LDFF surgery. Mean follow-up was 35 months (SD 3.6). Pre-and postoperative clinical assessment included the Foot and Ankle Outcome Score (FAOS) and a numeric rating scale (NRS) on pain at rest and during weight-bearing. Remodeling and bone ingrowth were analyzed on CT at one year post-operatively. Results: 15 out of 19 patients showed remodeling and bone ingrowth after the open LDFF procedure. Patients who did not show remodeling and bone ingrowth were treated by means of an OATS procedure. In the remaining 15 patients available at mid to long-term follow-up, LDFF led to a significant improvement of all FAOS subscales; FAOS-pain improved from 65 to 74 (p=0.014), FAOS-symptoms improved from 60 to 80 (p=0.005), FAOS-ADL improved from 80 to 85 (p=001), FAOS-sport improved from 38 to 61 (p=0.017) and FAOS-QoL improved from 38 to 64 (p=0.025). The NRS of pain at rest significantly improved from 3.2 to 1.2 (p=0.009), and pain during walking significantly improved from 6.5 to 1.6 (p<0.001). No complications occurred. Conclusion: Open LDFF of a talar OCDs show promising mid to long-term clinical and radiological results. A longer follow-up period with more study power is a subsequent necessary step in order to draw firmer conclusions about the longevity of this present procedure.

Category: Hindfoot, Midfoot/Forefoot Introduction/Purpose: Cavovarus foot alignment has been significantly associated with increased rates of chronic ankle instability and osteochondral lesions of the talus. Clinical wisdom suggests that cavovarus foot alignment causes varus stress to the ankle and also predisposes individuals to peroneal tendon pathology. However, no studies have specifically explored this relationship. The purpose of this research is to investigate the association between foot alignment and peroneal tendon pathology. Methods: A retrospective case-control study was conducted of all adult patients in whom a magnetic resonance image (MRI) of the ankle was obtained for any reason at a single institution from 2015-2017. Patients were excluded if they had a charcot foot deformity or if they had undergone prior peroneal tendon, ankle, or hindfoot surgery. Arch alignment was evaluated on lateral weightbearing radiographs of the foot by measuring the adjusted navicular height. Hindfoot alignment was assessed using the Saltzman apparent moment arm method. Peroneal tendon pathology including tears, tendinosis, and tenosynovitis was documented by a fellowship-trained musculoskeletal radiologist using the MRI scan. All numerical variables were converted to categorical variables (e.g. varus, valgus, and normal alignment). Chi-square testing was utilized to determine the association between variables. Results: 195 patients were included in the study (average age 47 years, 61% female). Patients with hindfoot varus had significantly higher rates of peroneus longus (PL) and peroneus brevis (PB) tendon pathology than patients with neutral or valgus alignment (Figure 1 A, B)(PL 39% vs. 31% vs. 20%, p=0.01; PB 44% vs 27% vs. 27%, p=0.04). Patients with pes cavus demonstrated extremely high rates of peroneal tendon pathology, which was significantly higher than patients with neutral or pes planus alignment (Figure 1 C, D)(PL 71% vs. 28% vs. 9%, p<0.0001; PB 75% vs 30% vs. 26%, p<0.0001). Amongst patients with peroneal tendon pathology, there was no difference in the rates of symptomatic vs. asymptomatic findings based on hindfoot or pes alignment. Conclusion: This is the first study to demonstrate a statistically significant association between cavus foot alignment, hindfoot varus alignment, and peroneal tendon pathology. Interestingly, this study demonstrates that patients with cavovarus alignment are not more likely to be symptomatic than patients with normal and planovalgus alignment. This study also reinforces the idea that peroneal pathology found on MRI may not necessarily need surgery, as it is frequently seen in patients without symptoms. This information may be useful in counseling patients considering operative treatment for peroneal tendon pathology and alignment abnormalities.
PROMIS Patient Reported Pain Outcomes Compared With Numerical Pain Score Before and After Ankle Surgery
Authors: Haskell Andrew , Kim Todd 
Published: October 2019

Category: Patient Reported Outcomes Introduction/Purpose: Patient reported outcomes (PRO) are important for measuring clinical changes after surgical intervention. This study compares PROMIS pain intensity, PROMIS pain interference, and a zero-to-ten numerical pain score (NPS) before and after three common ankle surgeries to test the hypothesis that pain improvement is measurable by each scale. In addition, the effects size (ES) of each scale is compared to help determine which scale may provide the most power to detect an improvement in pain. Methods: PRO scores were routinely collected during clinic visits between 2015 and 2018. Over 175 patients who had undergone total ankle replacement, subtalar fusion, or lateral ankle ligament stabilization were identified in the electronic health record using the surgical billing codes for these procedures. The most recent preoperative and postoperative PROs for these patients were compared by Mann-Whitney U, and effect size was calculated using Cohen’s d. Results: For total ankle replacement, NPS, pain intensity, and pain interference all improved (p<0.05) with ES 1.29, 0.95, and 0.63 respectively. For subtalar fusion, NPS, and pain interference improved (p<0.05) with ES 0.86 and 0.54; pain intensity (p=0.21) was unchanged with ES 0.30. For lateral ankle ligament stabilization, NPS, and pain interference improved (p<0.05) with ES 0.49 and 0.59; pain intensity (p=0.49) was unchanged with ES 0.19. Conclusion: While both NPS and PROMIS pain interference consistently demonstrated improvements after common ankle surgeries, NPS is preferable given its single question format and greater effect size in two of the three procedures studies. PROMIS pain intensity did not routinely measure changes in our surgical population questioning its utility.

Category: Ankle, Arthroscopy Introduction/Purpose: Osteochondral lesion of the talar dome (OLT) is common condition that causes pain of ankle joint in juvenile patients. Several surgical options have been available such as excision of detached cartilage fragment, microfracture, autologous cancellous bone graft and osteochondral autografting depending on the status of OLT. Arthroscopic drilling including transmalleolar or retrograde technique could be a good option for OLT patients with stable osteochondral fragment with normal articular surface. Retrograde drilling has an advantage in preventing the iatrogenic articular cartilage injury. This study aimed to clarify the clinical outcome of the retrograde drilling for OLT in juvenile patients. Methods: Our retrospective analysis included 8 patients who underwent retrograde drilling for OLT, in 5 boys and 3 girls, with a mean age of 14.9 years (range, 11-19). Range of motion (ROM) and American Orthopaedic Foot & Ankle Society (AOFAS) ankle- hindfoot score were evaluated as the clinical outcomes. OLTs were classified into 4 grades according to arthroscopic findings by international cartilage research society (ICRS) classification. Radiographic analysis was performed using preoperative and postoperative images. Growth plate was evaluated on plane radiographs, and the location and size of OLT were assessed on computed tomography. The high intensity area of the talus was also measured on T2 fat suppression images. Results: All 8 patients were followed with a mean follow-up period of 2 years, and they had no complication or revision surgery. The mean total ROM were 65.6° preoperatively and 67.1° postoperatively. AOFAS scale improved from 69.3 to 96.7 (p = 0.012). The ICRS 1 and 2 OLT lesions were identified arthroscopically in 5 and 3 patients, respectively. Growth plate remained open in 4 patients, and OLTs were located on the posteromedial in 7 patients, center in 1 patient. The mean size of OLT fragment was 9.8 mm, 6.8 mm and 3.5 mm in length, width and height. Coronal and sagittal T2 fat suppression images demonstrated that the high intensity area of 241.3 mm2, 554.5 mm2 at preoperative status and 190.9 mm2, 302.6 mm2 at final follow-up status. Conclusion: These findings revealed that the retrograde drilling remarkably improved clinical status in juvenile OLT patients. The high intensity area at the talus remained postoperatively, however, that did not affect clinical results. Retrograde drilling procedure should be considered for treating juvenile patients in the early period after detection of the OLT.

Category: Ankle Introduction/Purpose: The purpose of this study was to present the surgical technique and to evaluate the short-term clinical and radiological outcomes of a new press-fit OATS technique for large primary and secondary talar osteochondral defects of the talus, Talar OsteoPeriostic grafting from the Iliac Crest (TOPIC). Methods: Twenty-eight underwent a press-fit TOPIC procedure. Mean age was 38 years (SD 4.6). Pre- and postoperative clinical assessment at 12 months follow-up included the American Orthopaedic Foot & Ankle Society (AOFAS) score, the Short-Form 36 (SF-36) Mental Component Scale (MCS) and Physical Component Scale (PCS), the Numeric Rating Scales (NRS) of pain at rest, during walking and stairclimbing, and the Foot and Ankle Outcome Score (FAOS) including accompanying subscales. Remodeling of the contour of the talus, bone ingrowth and consolidation of the implanted graft were assessed on computed tomography (CT) one year post-operatively. Results: 28 out of 29 patients were available for follow up. The AOFAS significantly improved from 45 to 92 (p=0.001). The NRS on pain during rest improved from 3 to 0 (p=0.001), the NRS during walking improved from 5 to 1 and the NRS during stairclimbing also improved from 5 to 1 (p=0.001). Both components of the SF-36 improved. The PCS improved from 34 to 47 (p=0.001) and the MCS improved from 37 to 66 (p=0.001). Finally all FAOS subscales significantly improved. All patients were satisfied with the procedure and indicated that the level of functioning was good or very good. On the post-operative CT scans, all patients showed remodeling of the talus and all grafts showed consolidation as well as bone ingrowth. No complications occurred. Conclusion: The TOPIC procedure appears to be a very promising surgical treatment option for large primary and secondary talar OCDs. Despite these good short-term clinical and radiological outcomes, a prospective study with longer follow-up is necessary to assess the clinical outcome and the progression of osteoarthritis at the long term.

Published: October 2019

Category: Ankle, Trauma Introduction/Purpose: The purpose of this study was to investigate the immediate impact of removing symptomatic syndesmotic screws on PROMIS outcomes and ankle range of motion (ROM) in patients who had previously undergone ankle fracture open reduction and internal fixation (ORIF) and syndesmotic fixation and later experienced symptomatic syndesmotic screws and functional limitation. Methods: A total of 346 ankle fractures were treated from February 2015 to May of 2018. 58 patients with ankle fractures with syndesmotic instability and fixation who underwent syndesmotic screw removal (SSR) were included in the analysis. Cohort data was collected for 71 patients who underwent ORIF with syndesmotic fixation, but without screw removal during the same study period. Results: Patients who underwent SSR had a statistically significant improvement in the physical function (PF) T-score to 44.5 (p<0.01) in the early post-operative period (average 48 days) after screw removal. The screw removal occurred an average of 184 days after initial ORIF. This PF T-score change also met the minimally clinically important difference. There was no significant difference in PF T-scores between the SSR group and cohort comparison group (44.5 vs 41.6; p=0.06) after screw removal. Removal of symptomatic implants resulted in an early improvement of total arc ankle ROM by 20° (p<0.01). Conclusion: There was an early clinically meaningful and statistically significant improvement in physical function outcomes and ankle ROM after symptomatic syndesmotic screw removal for patients who underwent ankle fracture ORIF with syndesmotic fixation. The final outcomes after screw removal in these patients was similar to the outcomes of asymptomatic patients who did not require syndesmotic screw removal within the same post-operative timeframe.

Category: Ankle, Arthroscopy, Hindfoot, Sports, Trauma Introduction/Purpose: Surgical management of osteochondral lesions of the talus (OLT) present an ongoing treatment challenge. Previously, matrix-induced autologous chondrocyte implantation (MACI) demonstrated improved pain and function at 7-years postoperative, providing evidence that MACI is a reliable method for treating cartilage. However, it is unknown the long- term results of MACI in OLT. The purpose of this study was to assess 13-year clinical follow-up data and the long-term success of this implant by comparing patient reported outcome measures (PROMs) pre-operatively, at 7-years post-operative, and at 13- years post-operative. Methods: A prospective investigation of MACI was performed on 10 patients with OLTs who had failed previous arthroscopic treatment. Of the 10 patients, 9 were available for 7-year and 13-year follow-up. Short Form Health Survey (SF-36) and the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot evaluation were utilized at pre-operative, 7-year, a 13-year postoperative. For each patient, a paired t-test was used to compare 13-year post-operative PROMs to pre-operative PROMs. A single factor analysis of variance (ANOVA) determined whether PROMs were different between pre-operative, 7-year post- operative, and 13-year post-operative time intervals. When a significant difference was detected, a post-hoc Tukey’s determined which time periods were different. Results: SF-36 data at 13-years showed significant improvements in Physical Functioning (p=0.012), Lack of Bodily Pain (p=0.017), and Social Functioning (p=0.007) compared with preoperative data. There were no differences in other components of the SF-36 outcomes (p>0.05). Although the AOFAS was on average 12 points higher at 13-years postoperative, this was not statistically significant (p=0.173). As for comparing PROMs over time, 13-years post-operative PROMs were comparable to 7-years post- operative (Table 1). There were better PROMs for Physical Functioning, Bodily Pain, and Social Functioning at 7- and 13-years post-operative compared to pre-operative while Physical Role Functioning was also better at 7-years post-operative compared to pre-operative. Conclusion: This study shows MACI provides greater pain relief and function at 13-years post-operative with stable long-term follow-up. MACI should be considered for osteochondral lesions that fail initial microfracture.

Category: opioid consumption Introduction/Purpose: The expanding opioid crisis has forced orthopedic surgeons to evaluate their prescribing practices, yet there remains limited evidence to guide providers in achieving safe and effective postoperative analgesia. Our goal was to prospectively evaluate opioid consumption following outpatient foot and ankle surgery and determine predictors of increased narcotic usage. Methods: We prospectively enrolled adult patients scheduled for outpatient foot and ankle surgery and conducted phone and in- person interviews postoperatively to determine pain level, number of pills consumed, satisfaction with pain control, and whether other analgesic medication was used. Interviews were performed at four separate time points: 5 days, 10 days, 2 weeks, and 6 weeks following surgery. Additional data collected included age, gender, payer status, education level, preoperative pain level, procedure performed, whether opioid pain medication had been used by the patient in the 12 months preceding surgery, and the amount of narcotic prescribed postoperatively. Results: Complete data was available for 52 patients (median age, 42 years). The median number of opioids prescribed postoperatively was 45 pills (337.5 morphine milligram equivalents (MMEs)). A refill narcotic prescription was provided for 36.5% of patients. The number of opioid pills consumed following surgery ranged from 0 to 120 (median, 40 pills). Forty-six percent of patients had discontinued the use of opioids by post-op day 10 and 86.5% by post-op day 20. Increased pre-operative pain level (p = 0.02) and an increased quantity of pills prescribed at the first prescription (<0.0001) were significantly associated with increased narcotic consumption. Eighteen (39.1%) patients filled a narcotic prescription in the 12 months prior to surgery, however, narcotic use prior to surgery did not significantly increase total opioid consumption. Conclusion: We found that the median number of opioids consumed following outpatient foot and ankle surgery was 40 pills. Nearly 90% of patients had discontinued narcotic use by 20 days postoperatively. Pre-operative pain level and the number of pills provided at the first prescription were predictive of increased narcotic usage.

Authors: Zhang Mingzhu , Yu Guangrong 
Published: October 2019

Category: Midfoot/Forefoot, Trauma Introduction/Purpose: Prospective analyses of treatment for the first tarsometatarsal joint dislocation with Lisfranc injury. Comparison of open reduction internal fixation (ORIF) and primary arthrodesis was conducted for the injury. Methods: 78 Lisfranc injuries with first tarsometatarsal joint dislocation underwent surgical intervention. They were 46 males and 32 females with mean age of 41.2 years. Two groups were randomized by ORIF group and primary arthrodesis group. 43 patients were performed by ORIF, while primary arthrodesis group including 35 cases. Outcome measures included radiographs, AOFAS scores, VAS and SF-36 scores. Complications and revision rate were analyzed also. Results: 73 patients were followed up for 21 months. At 1.5 years postoperatively, the AOFAS score was 75 and 83 in ORIF group and arthrodesis group. The VAS score was 3.0 and 2.1 separately in two groups. The mean Physical Functioning sores of SF- 36 was 81.2 points and 84.1 points. The Bodily Pain score of SF-36 was 79.3 points and 85.2 points. Redislocation of first tarsometarsal joint were observed in 11 cases among ORIF group.31 patients in ORIF group had pain in midfoot, six of them had persistent pain with the development of deformity or osteoarthrosis. No redislocation and no hardware failure was identified in arthrodesis group. Conclusion: Primary stable arthrodesis of the first ray gives a better short and medium term outcome than open reduction and internal fixation for Lisfranc injury with the first ray dislocation. Possible complication and revision could be avoided by primary arthrodesis for dislocated first ray injuries.

Published: October 2019

Category: Ankle, Ankle Arthritis, Hindfoot Introduction/Purpose: A variety of operative approaches and fixation techniques have been described for tibiotalar (TT) and tibiotalocalcaneal (TTC) arthrodesis. In the past two decades, authors have begun to more robustly examine outcomes of the transfibular approach for TT arthrodesis and expanded its indication to include TTC fusion. The transfibular technique is broadly divided into two categories: 1) Complete excision of fibula 2) Soft tissue preservation techniques with retention of fibula. The purpose of this study was to retrospectively assess the surgery outcomes in transfibular approach and compare the fibula excision versus fibula retention techniques and examine the factors that play into the risk. Methods: Following institutional review board approval, a retrospective review was performed on all patients who underwent TT and TTC arthrodesis through a lateral transfibular approach with minimum 1 year clinical and radiologic follow up. All other operative approach and fixation combinations for arthrodesis were excluded. Primary outcomes examined were union rate, revisions, and complications related to fibula excision versus retention group. Sixteen patients underwent TT and TTC arthrodesis with fibular retention and twelve with fibular excision techniques. Results: The overall union rate was 89%, 87% (14 of 16 ankles) for the fibula retention group, and 91% (11 of 12) for fibula excision group (P = .72). Symptomatic nonunion requiring revision arthrodesis occurred in 6% (1 of 16) of the retention group versus 8% (1 of 12) in the excision group (P = .83). There were no significant differences in individual tibiotalar or subtalar union, reoperation, superficial wound problems, infection and symptomatic hardware rates. Elective hardware removal was performed in 12%(2of 16) in fibular retention group versus 25%(3 of 12) in fibula excision group (P = .39), none of the hardware removal was related to the fibula fixation. Each group had three episodes of reoperation due to non-union, osteomyelitis and painful hardware. Conclusion: Union, reoperation rates were similar in fibula resection versus retention groups. The frequency of infection and wound complication was not significantly different in both groups, despite the wide variety of patient population and preoperative indications.
