Manual Manipulation

Ankle equinus is a well-known clinical entity that has previously been shown to compound a variety of foot and ankle conditions. Treatments for this disorder have included surgery to lengthen the Achilles tendon and daily stretching. This article describes a method of manual manipulation that can immediately and substantially increase ankle joint dorsiflexion. Patients treated with manipulation in the current study demonstrated nearly twice as much dorsiflexion motion as that demonstrated by patients in a prior study who were treated with a 5-minute daily stretching program for 6 months.

Background The definition of equinus varies from less than 0° to less than 25° of dorsiflexion with the foot at 90° to the leg. Despite its pervasive nature and broad association with many lower-extremity conditions, the prevalence of ankle equinus is unclear. Furthermore, there are few data to suggest whether equinus is predominantly a bilateral finding or isolated to the affected limb only. Methods We conducted a prospective cohort study examining consecutive patients attending a single foot and ankle specialty practice. Participation involved an assessment of ankle joint range of motion by a single rater with more than 25 years of clinical experience. We defined ankle equinus as ankle joint dorsiflexion range of motion less than or equal to 0° and severe equinus as less than or equal to –5°. Patients who had previously experienced an Achilles tendon rupture, undergone posterior group lengthening (ie, Achilles tendon or gastrocnemius muscle lengthening), or had conservative or surgical treatment of equinus previously were excluded. Results Of 249 included patients, 61% were female and 79% nondiabetic. The prevalence of ankle equinus was 73% [183 of 249], and nearly all of these patients had bilateral restriction of ankle joint range of motion (prevalence of bilateral ankle equinus was 98.4% [180 of 183] among those with equinus). We also found that ankle equinus was more common in patients with diabetes, higher body mass indexes (BMIs), or overuse symptoms. Conclusions The prevalence of ankle equinus in this sample was higher than previously reported, and nearly all of these patients had bilateral involvement. These data suggest that many people attending foot/ankle specialty clinics will have ankle equinus, and select groups (diabetes, increased BMI, overuse symptoms) are increasingly likely.

Tendon Ruptures

Category: Sports Introduction/Purpose: Diabetes Mellitus (DM) is an epidemic affecting millions of individuals in the United States. Multiple studies have demonstrated an increase in complications in foot and ankle surgery in patients with DM, including wound healing complications, surgical site infections (SSI), or surgical failure. The goal of this study was to retrospectively review outcomes data from the National Surgical Quality Improvement Program (NSQIP) to determine the impact of DM on operative treatment of achilles tendon ruptures. Methods: Using the NSQIP from 2006-2015, patients were identified using common procedure terminology (CPT) for Achilles tendon ruptures. Diabetic and non-diabetic cohorts were evaluated to compare demographics, comorbidities, perioperative details and 30-day outcomes. Statistical evaluation included a power analysis for the primary outcome measure of wound disruption as well as univariate analysis was performed using chi-squared or Fisher’s exact and Wilcoxon signed-rank tests. Results: A total of 2,014 patients were identified having sustained an Achilles tendon rupture. There were 1,981 patients without DM and 33 patients with DM. There were no significant differences in postoperative complications, including SSI, medical complications, and 30-day outcomes between patients with DM and non-DM patients undergoing surgical repair of acute Achilles tendon ruptures. The power analysis for wound disruption showed a P=0.9 with an alpha of 0.05, sample size of n=2014, and Pearson correlation coefficient of r=0.0721 Conclusion: While DM has been shown to have an increase in complications in various foot and ankle procedures, this study demonstrates that there is no significant difference in postoperative complications and 30-day outcomes between patients with DM and non-DM patients undergoing surgical repair of acute Achilles tendon ruptures using the NSQIP database from 2006-2015. Based on this data, patients with diabetes mellitus can be considered adequate surgical candidates for acute Achilles tendon rupture repair.

Background: Clinical measurement of passive dorsiflexion of the ankle joint is essential for the diagnosis of various pathologic conditions of the foot and ankle but is of unreliable precision with high interobserver variability in nonweightbearing tests. This work was designed to develop and test a precise, standardized, and reliable technique for measurement of passive and active ankle range of motion. Methods: The proposed measurement tool is composed of two mobile parallelograms, one attached to the tibia, the second one to the plantar surface of the foot. The parallelograms are connected with a hinge with an angular scale to measure the angle between the foot and tibia. Results: Interobserver correlation between clinical measure-ments for maximal passive foot dorsiflexion were 0.03 with knee extension and 0.38 with knee flexion, while for measurements with the proposed tool they reached 0.89 and 0.97, respectively, with a mean measurement error of 0.9 degrees. Intraobserver correlations reached values of r = 0.98 and 0.99. Conclusions: The proposed tool allows measurement of the ankle range of motion with very high precision and reproducibility far superior to clinical measurements. Clinical Relevance: Precise measurement of ankle range of motion is clinically challenging. With the use of the proposed tool, measurement precision and reliability are decisively improved.

Category: Sports; Other Introduction/Purpose: Achilles tendon ruptures are a common sporting injury, mostly occurring in men over the age of 40. Operative repair of Achilles tendon can lead to earlier return to activity and improved function in the active population. Mini-open repairs have recently been described for effective treatment of Achilles tendon ruptures. We aim to describe our unique mini- open Achilles tendon repair technique and to report our clinical outcomes. Methods: We retrospectively reviewed charts of patients from January 2010 and July 2019 who underwent a 3cm mini-open Achilles tendon repairs, without additional targeting devices, for closed acute Achilles tendon ruptures. Patients were followed up for a minimum of one year. We recorded pre- and postoperative Foot and Ankle Disability Index (FADI), visual analog scale (VAS), and the Foot and Ankle Outcome Score (FAOS) scores. Subgroup analysis were performed for acute repairs (< 2 weeks) and subacute (2-6 weeks). Two-sided student’s t-test to compare preoperative and postoperative outcomes for continuous variables. Chi-square analyses were used to determine the strength of correlation between categorical variables. A p-value of < .05 was considered significant for all statistical analyses. Results: A total of 33 patients met the inclusion criteria and are included in this study. The mean age of our cohort was 43.8 years old (range 22-78) and 78.8% of patients were male. The mean length of follow-up was 4.4 years (range 1.0-9.8 years). The mean time from injury to surgery was 15.6 days (1-45 days). Patients reported a mean return to their previous level of activity at a mean of 5.6 months (range 1.7-22.1). The mean pre- and postoperative outcomes scores improved significantly for both the acute and subacute repair groups (p < 0.05). There were no significant differences for postoperative outcomes scores between the acute and subacute Achilles repair groups (p > 0.05). There were no reported complications in our patient cohort. Conclusion: Patients showed improvements in postoperative patient-reported outcome scores with minimal complications. There were no significant difference in outcomes for acute versus subacute repairs. Our mini-open Achilles tendon repair, which required no additional targeting instrumentation, has shown favorable mid-term results.

The Difference

Category: Pathophysiology Introduction/Purpose: Gastrocnemius eqiunus has been associated with a wide range of foot and ankle pathologies in the literature, however, many still question it’s involvement or existence. A recent response in Foot & Ankle International pointed out an incorrect demonstration of the Silfverskold test in a prior study. With a growing body of literature supporting gastrocnemius equinus as a contributing factor in foot and ankle pain, why do many feel that it still does not exist? It was our hypothesis that unless the examination is performed correctly, the diagnosis can be missed and could be the potential cause for disbelief in its existence or effect on foot and ankle pain. We sought to demonstrate the difference in examination findings when performing the test correctly and incorrectly. Methods: Thirty consecutive patients with conditions associated with gastrocnemius equinus in the literature were included in the study. Each patient was consented and had a Silverskold test performed correctly by inverting and locking the subtalar joint as well as stabilizing the talonavicular joint in order to isolate the ankle joint. We then performed the exam incorrectly without stabilizing the same two joints, allowing motion through the ipsilateral hindfoot and midfoot joints. A long arm goniometer was used to measure the angles with each arm along the length of the fibula and fifth metatarsal. The senior author performed all of the examinations to maintain consistency. The angles were recorded for later review. Results: We found that when the subtalar and talonavicular joints were stabilized, there was almost fifteen degrees less dorsiflexion than when the same joints were not stabilized. The average dorsiflexion when performed in the correct manner was seventy-eight degrees, while the average dorsiflexion with the exam performed incorrectly was ninety-three degrees. Conclusion: We demonstrated that if the examination is not performed correctly, the equinus contracture could go undiagnosed as motion through the hindfoot and midfoot joints can alter the findings. It is important to understand and perform the technique correctly to evaluate for the contracture as it has been shown to be a contributing factor in many foot and ankle problems. If we standardize the examination, there may be less disagreement about its existence or affect on foot and ankle pain.

The present study investigated the mechanical role of the dorsoventral curvature of the Achilles tendon in the conversion of the shortening of the plantarflexor muscles into ankle joint rotation. Dynamic, sagittal-plane magnetic resonance spin-tagged images of the ankle joint were acquired in six healthy subjects during both passive and active plantarflexion movements driven by a magnetic resonance compatible servomotor-controlled foot-pedal device. Several points on these images were tracked to determine the 1) path and deformation of the Achilles tendon, 2) ankle's center of rotation, and 3) tendon moment arms. The degree of mechanical amplification of joint movement was calculated as the ratio of the displacements of the calcaneus and myotendinous junction. In plantarflexion, significant deflection of the Achilles tendon was evident in both the passive (165.7 ± 7.4°; 180° representing a straight tendon) and active trials (166.9 ± 8.8°). This bend in the dorsoventral direction acts to move the Achilles tendon closer to the ankle's center of rotation, resulting in an ∼5% reduction of moment arm length. Over the entire range of movement, the overall displacement of the calcaneus exceeded the displacement of the myotendinous junction by ∼37%, with the mechanical gains being smaller in dorsi- and larger in plantarflexed joint positions. This is the first study to assess noninvasively and in vivo using MRI the curvature of the Achilles tendon during both passive and active plantarflexion movements. The dorsoventral tendon curvature amplifies the shortening of the plantarflexor muscles, resulting in a greater displacement of the tendon's insertion into the calcaneus compared with its origin.

Background: We report the clinical outcomes and complications following our limited open incision Achilles tendon repair technique without instrument guides. Methods: A total of 33 patients were included in this study. We recorded pre- and postoperative scores on the Foot and Ankle Disability Index (FADI), visual analog scale (VAS), and the Foot and Ankle Outcome Score (FAOS). Subgroup analyses were performed for acute (<2 weeks) and subacute (2-6 weeks) Achilles tendon repairs. A P value <.05 was considered significant for all statistical analyses. Results: The median time from injury to surgery was 10.0 days (range, 1-45 days). At a median follow-up of 3.7 years (range, 1.0-9.8 years), the average pre- and postoperative outcome scores improved significantly for the following: FADI index (49.1-98.4, P < .001), VAS (4.8-0.2, P < .001), FAOS Pain (54.8-99.2, P < .001), FAOS Symptoms (84.6-97.0, P < .001), FAOS activities of daily living (61.4-97.2, P < .001), FAOS Sports and Recreational Activity (39.5-98.5, P < .001), and FAOS quality of life (39.7-88.7, P < .001). There were no significant differences between pre- and postoperative outcome scores between the acute and subacute Achilles repair groups. There were no wound complication, reruptures, or reoperations in the entire cohort. Conclusion: Patients showed improvements in postoperative patient-reported outcome scores with minimal complications. There was no significant difference in outcomes for acute vs subacute repairs. Our limited open incision Achilles tendon repair, which required no additional targeting instrumentation, had favorable midterm results. Level of Evidence: Level IV, retrospective case series.

Category: Ankle; Ankle Arthritis Introduction/Purpose: Deficits in ankle joint kinetics following total ankle arthroplasty (TAA) may be attributed to a reduction in the force-generating capacity of ankle joint muscles, but it is also important to consider the alterations to joint structure that may accompany this procedure. One key parameter indicative of joint structure with the potential to be influenced by TAA is the plantarflexion moment arm of the Achilles tendon (ATma). ATma is an indicator of the potential for the tendon force to produce plantarflexion moment that is determined by the three-dimensional line of action of the tendon relative to the ankle joint axis. The purpose of this study was to assess pre-to-post TAA changes in ATma; we hypothesized that pre- and post-TAA moment arms would not be different. Methods: We tested 10 TAA patients (age at surgery: 62.86 +- 9.72 y; height: 1.72 +- 0.08 m; body mass: 97.81 +- 20.89 kg) at pre-operative (˜ 1 mo pre) and post-operative (˜6 mo post) visits. All procedures involving testing of human subjects were approved by the Penn State Hershey Medical Center Institutional Review Board. ATma were measured using a method that combined ultrasound imaging of the tendon with 3D motion tracking of both the ultrasound probe and the ankle joint. The tendon and joint axis were located during trials in which the patients were seated with the knee extended while the ankle joint was voluntarily rotated in the sagittal plane. We also examined sagittal-plane weightbearing radiographs (pre- and post-op) to determine the AP distance from the center of the talar dome to the posterior margin of the calcaneus. Pre- and post-op ATma were compared using a paired t-test and regression. Results: No significant mean differences were found between post-op ATma and pre-op ATma (p = 0.360). Despite this, some patients were found to have large differences between pre- and postoperative ATma. For example, participants 1, 3, and 8 exhibited changes of -54.22%, +64.14% and +123.98% (pre-to-post) respectively (Figure 1). A moderate correlation between pre- and post-op ATma was found (r2 = 0.461, p = 0.031), indicating that only 46.1% of the variance in post-op ATma was explained by pre-op ATma (Figure 1). The normalized AP distance measured from the radiographs did not significantly change on average pre- to post-TAA (p = 0.561), and we found the change in this distance to correlate with the change in ATma (r2 = 0.370, p = 0.062). Conclusion: This is the first investigation of whether TAA alters ATma. Our results supported our hypothesis that pre-operative ATma predicts post-operative ATma. However, our hypothesis is supported only when the mean differences are considered, as there were sizeable differences for individuals. Despite a non-significant average change in ATma following TAA, at the individual level substantial changes in ATma were observed in seven of the 10 patients. Change in ATma was only partly explained by change in the AP position of the talar dome. Change in ATma has potential consequences for function in terms of ankle plantarflexor strength and walking velocity.
