Background: Treatment of osteochondral lesions of the talus (OLTs) in children presents a difficult clinical challenge, with few large series reported. Purpose: To evaluate functional and radiographic outcomes for children and adolescents undergoing arthroscopic treatment of symptomatic OLT with a minimum follow-up of 2 years. Study Design: Case series; Level of evidence, 4. Methods: Patients were identified who had symptomatic OLT treated arthroscopically with marrow stimulation techniques. Inclusion criteria were age ≤18 years, symptomatic chronic OLT as the surgical indication, failure of nonoperative treatment, and minimum follow-up of 24 months. Outcome measures included Foot Function Index, American Orthopaedic Foot and Ankle Society Hindfoot Score, Tegner Activity Scale, 36-Item Short Form Health Survey (Short Form-36, v 2), visual analog scale, ankle range of motion, and patient satisfaction survey. Weightbearing radiographs were compared with preoperative radiographs via an ankle arthritis classification system. Magnetic resonance imaging (MRI) was used to evaluate postoperative lesion characteristics per the MOCART scale (magnetic resonance observation of cartilage repair tissue). The size, location, lesion stability, traumatic etiology, skeletal maturity, and length of follow-up were recorded and analyzed through univariate logistic regression. Results: The study group consisted of 22 patients (11 male, 11 female) with a mean age of 14.4 years (range, 8-18 years) and a mean follow-up of 8.3 years (range, 2-27 years). Of 22 patients, 20 were satisfied with the results from surgery and would recommend it to others. Mean follow-up visual analog scale for pain was reported as 2.2 on a 10-point scale, and mean American Orthopaedic Foot and Ankle Society score at follow-up was 86.6. Mean postoperative Foot Function Index scores for the study group were as follows: pain, 17.1; disability, 16.5; activity, 4.7; and overall, 38.7. Mean Short Form-36 physical component score was 50.7. Postoperative radiographs indicated a van Dijk osteoarthritis grade of 0 in 56%, I in 38%, II in 6%, and III in 0%. Postoperative MRI MOCART scores showed complete filling of the cartilage in 27% of cases, complete graft integration in 22%, and intact repair surface in 22%, with a mean MOCART score of 48.0. No correlation was found between radiographic and MRI findings and clinical outcomes. None of the prognostic factors were significantly associated with patient satisfaction, progression of arthritis, or MOCART scores. Conclusion: Arthroscopic treatment of symptomatic OLT in adolescent patients (≤18 years) demonstrated high functional outcomes, high clinical satisfaction rates, and minimal radiographic osteoarthritic progression despite low MOCART scores.

Background: Autologous matrix-induced chondrogenesis (AMIC) has become an interesting treatment option for osteochondral lesions of the talus (OLTs) with promising clinical short- to midterm results. Purpose: To investigate the clinical and radiological outcome of the AMIC procedure for OLTs, extending the follow-up to 8 years. Study Design: Case series; Level of evidence, 4. Methods: Thirty-three patients (mean age, 35.1 years; body mass index, 26.8) with osteochondral lesions of the medial talar dome were retrospectively evaluated after open AMIC repair at a mean follow-up of 4.7 years (range, 2.3-8.0 years). Patients requiring additional surgical procedures were excluded. All OLTs (mean size, 0.9 cm2; range, 0.4-2.3 cm2) were approached through a medial malleolar osteotomy, and 28 patients received subchondral autologous bone grafting. Data analysis included the visual analog scale for pain, the American Orthopaedic Foot and Ankle Society score for ankle function, the Tegner score for sports activity, and the MOCART (magnetic resonance observation of cartilage repair tissue) scoring system for repair cartilage and subchondral bone evaluation. Results: Mean ± SD visual analog scale score improved significantly from 6.4 ± 1.9 preoperatively to 1.4 ± 2.0 at latest follow-up ( P < .001). The mean American Orthopaedic Foot and Ankle Society score was 93.0 ± 7.5 (range, 75-100). The Tegner score improved significantly from 3.5 ± 1.8 preoperatively to 5.2 ± 1.7 at latest follow-up ( P < .001), and 79% returned to their previous sports levels. The MOCART score averaged 60.6 ± 21.2 (range, 0-100). Complete filling of the defect was seen in 88% of cases, but 52% showed hypertrophy of the cartilage layer. All but 1 patient showed persistent subchondral bone edema. The patient’s age and body mass index, the size of the osteochondral lesion, and the MOCART score did not show significant correlation with the clinical outcome. There were no cases of revision surgery for failed AMIC. Fifty-eight percent underwent reoperation, mainly for symptomatic hardware after malleolar osteotomy. Conclusion: AMIC for osteochondral talar lesions led to significant pain reduction, recovery of ankle function, and successful return to sport. The MOCART score did not correlate with the good clinical results; the interpretation of postoperative imaging remains therefore challenging.

Marrow Edema

Background Bone marrow edema (BME) of the talus is a rare, mostly self-limiting cause of foot and ankle pain. We sought to investigate in patients with idiopathic BME of the talus the effectiveness of pulsed electromagnetic fields and to determine the effect of this therapy on magnetic resonance imaging findings. Methods Six patients with BME of the talus confirmed by magnetic resonance imaging were enrolled. Pain was quantified with a visual analog scale from 0 (no pain) to 10 (the worst pain imaginable). The clinical outcome was assessed using the American Orthopaedic Foot and Ankle Society scoring system. Treatment consisted of pulsed electromagnetic field stimulation 8 h/d for 30 days. The device used generated pulses 1.3 milliseconds in duration, with a frequency of 75 Hz and a mean ± SD induced electric field of 3.5 ± 0.5 mV. Results The mean American Orthopaedic Foot and Ankle Society score improved from 59.4 (range, 40–66) before treatment to 94 (range, 80–100) at the last follow-up. The visual analog scale score decreased significantly from 5.6 (range, 4–7) before treatment to 1 (range, 0–2) at the last follow-up. Magnetic resonance imaging showed that BME improved after 1 month of treatment and resolved completely within 3 months in 5 patients, with normal signal intensity and no signs of progression to avascular necrosis. Conclusions A significant reduction in BME area was associated with a significant decrease in pain within 3 months of beginning treatment.

The Impact

Background: The purpose of the study was to assess the functional and radiologic outcomes after AT-AMIC (arthroscopic talus autologous matrix–induced chondrogenesis) in 2 weight groups of patients with osteochondral lesions of the talus (OLTs): patients with BMI <25 (Healthy Weight Group [HG]) and with BMI ≥25 (Overweight Group [OG]). Methods: Thirty-seven patients were evaluated. HG was composed of 21 patients (BMI = 21.90 ± 1.94), whereas OG consisted of 16 patients (BMI = 27.41 ± 1.98). All patients were treated with AT-AMIC repair for OLTs. Magnetic resonance imaging (MRI), computed tomography (CT), Visual Analgoue Scale (VAS) for pain, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle and Hindfoot score and Short-Form Health Survey (SF-12) were administered preoperatively (T0) and at 6 (T1), 12 (T2), and 24 (T3) months postoperatively. Results: In both groups, we found a significant difference for clinical and radiologic parameters with analysis of variance for repeated measures through 4 time points ( P < .001). In HG, AOFAS increased at every follow-up ( P < .05), whereas in OG, AOFAS improved only between T2 and T3 ( P = .0104). In OG we found a significant difference comparing CT and MRI at each follow-up; in HG this difference was found only at T0 ( P < .0001) and T1 ( P = .0492). Finally, OG presented a significantly larger lesion measured with MRI at T0 ( P = .033). Conclusions: OLTs in overweight patients were characterized by a larger preoperative size. At final follow-up, both groups showed a significant clinical improvement. AT-AMIC can be considered a safe and reliable procedure, regardless of weight, with a significant improvement also in quality of life. Level of Evidence: Level III, comparative study.

There has been no consensus on the treatment or prognosis of Hepple stage V osteochondral lesions of the talus (OLTs), especially for lesions greater than 1.5 cm2in size. The objective of this study was to investigate the clinical outcomes achieved upon application of a platelet-rich plasma (PRP) scaffold with a cancellous bone autograft for Hepple stage V OLTs. Fourteen patients (mean age, 39 years) were treated with a cancellous bone graft and a PRP scaffold between 2013 and 2015. The mean time to surgical treatment was 23.5 months. Ankle X-ray and magnetic resonance imaging were performed at the final follow-up. Functional outcomes were evaluated according to the Visual Analog Scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and Short Form 36 (SF-36) score. The range of motion (ROM) of the ankle joint and complications also were recorded. Thirteen patients completed the full follow-up, with a mean follow-up duration of 18 months. MRI demonstrated the complete regeneration of subchondral bone and cartilage in all patients. The postoperative VAS, AOFAS ankle and hindfoot, and SF-36 scores were improved significantly (allP<0.001) without obvious complications. We suggest that, for the Hepple stage V OLTs, management with cancellous bone graft and PRP scaffold may be a safe and effective treatment.

Background The purpose of the present study was to retrospectively compare the outcomes of patients who underwent arthroscopic thermal capsular shrinkage with those who underwent both arthroscopic thermal capsular shrinkage and arthroscopic osteochondral lesion (OCL) treatment with microfractures. Our hypothesis was that the simultaneous treatment does not negatively affect the outcome of the combined surgical procedure by influencing the postoperative rehabilitation protocol and does not significantly differ from capsular shrinkage alone in terms of subjective and objective outcomes. Methods Seventy-six patients with chronic ankle instability were treated at our department from 2004 to 2012 and reviewed retrospectively. Forty-two patients underwent arthroscopic thermal-assisted capsular shrinkage (group A), and 34 patients underwent combined arthroscopic capsular shrinkage and microfractures for OCL lesions of the talus (group B). All patients underwent a four-step surgical procedure including synovectomy, debridement, capsular shrinkage, and bracing and nonweightbearing for 21 days. In patients with OCL lesions, microfractures of the OCL were associated. Clinical assessment included objective examination, the American Orthopaedic Foot and Ankle Society ankle and hindfoot scoring system, Karlsson-Peterson score, Tegner activity level, and Sefton articular stability scale. Results The median follow-up was 6 years (range, 2–9 years). The median postoperative visual analogue scale score, American Orthopaedic Foot and Ankle Society score, and Tegner score were improved from the preoperative level for both groups (P &lt; .001). No significant difference was found between the two groups for the subjective scores and satisfaction rate (P = not significant). Similarly, no significant difference regarding the incidence of range-of-motion restriction was reported between the two groups (P = not significant). Conclusions The association of microfractures for the treatment of osteochondral lesions does not affect the outcome following arthroscopic treatment for chronic ankle instability up to 6 years from surgery.

Background. Osteochondral lesions of the talus (OLT) are difficult to treat because of the poor intrinsic healing capability of articular cartilage. Matrix-induced autologous chondrocyte implantation (MACI) has been shown to be a reliable method for treating cartilage lesions that fail to respond to traditional microfracture and debridement. The purpose of this study was to assess 7-year clinical follow-up data of this technique and demonstrate midterm success of this implant. Methods. A prospective investigation of MACI was performed on 10 patients with OLTs who had failed previous arthroscopic treatment. In all, 5 male and 5 female patients were included in the study. Of the 10 patients, 9 were available for 7-year follow-up. Functional and clinical evaluations were done at 7 years postoperatively using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot evaluation and the Short Form Health Survey (SF-36) and compared with preoperative values. Results. SF-36 data at 7 years showed significant improvements in Physical Functioning (P < .01), Lack of Bodily Pain (P < .1), and Social Functioning (P < .001) compared with preoperative data. The mean AOFAS hindfoot scores of the 9 patients at 7 years was 78.3 ± 18.1 (P = .05) compared with their preoperative mean of 61.8 ± 14.3. Conclusions. MACI provides a stable midterm chondral replacement strategy for osteochondral lesions that fail initial microfracture. Levels of Evidence: Level IV: Prospective case series

Category: Ankle; Arthroscopy Introduction/Purpose: The purpose of the present study was to evaluate the outcomes of arthroscopic microfracture for osteochondral lesions of the talus, in patients of older than 60 years old. Methods: Sixteen patients (16 ankles) with osteochondral lesions of the talus were treated by arthroscopic microfracture from October 2012 to June 2019. As two patients were lost to follow-up, Fourteen patients (14 ankles) participated in the study. There were 6 men (42.9%) and 8 women (57.1%) of average age 67.4years (range 60-77) at the time of surgery. Clinical outcome evaluations were performed using Foot and Ankle Outcome Score (FAOS) and patient’s satisfaction after surgery at a mean follow-up of 50.8 months. Results: Mean FAOS scores improved from SYMPTOM 68.2 points (range 39-86), PAIN 65.1 points (range 36-94), ADL 69.4 points (range 32-99), SPORTS 45.4 points (range 25-80), QOL 47.1 points (range 13-94) preoperatively to SYMPTOM 94.8 points (range 68-100), PAIN 91.1 points (range 48-100), ADL 93.3 points (range 59-100), SPORTS 71.8 points (range 30-100), QOL 79.8 points (range 25-100) at final follow up. Very satisfaction in 4 (29%), Satisfaction in 7 (50%), Fair in 2 (14%), Dissatisfaction in 1 (7%), and reason for dissatisfaction was persistent pain after surgery. Conclusion: Arthroscopic microfracture for osteochondral lesions of the talus is a safe and effective procedure for old age patient.

In this retrospective study, we aim to assess the safety and feasibility of adapting subtalar arthroereisis (SA) for type I osteogenesis imperfecta (OI) patients with symptomatic flatfoot. From December 2013 to January 2018, six type I OI patients (five girls and one boy, 12 feet) with symptomatic flexible flatfoot were treated with SA and the Vulpius procedure. All the patients were ambulatory and skeletally immature with failed conservative treatment and unsatisfactory life quality. The median age at the time of surgery was 10 years (range 5–11), and the median follow-up period was 55 months (range 33–83). All functional and radiographic parameters improved (p < 0.05) after the procedure at the latest follow-up. The median American Orthopaedic Foot and Ankle Society ankle-hindfoot scale improved from 68 (range 38–80) to 95 (range 71–97). All of the patients ambulated well without significant complications. The weight-bearing radiographs showed maintained correction of the tarsal bone alignment with intact bony surfaces adjacent to implants during the post-operative follow-up period. This is the very first study on symptomatic flatfoot in pediatric patients with type I OI. Our data suggest that SA is a potentially viable approach, as functional improvements and maintained radiographic correction without significant complication were observed.

Objective Arthroscopic “one-step” technique based on bone marrow–derived cell transplantation (BMDCT) have achieved good results in repairing osteochondral lesions of the talus (OLT), overcoming important drawbacks of older techniques. It may be particularly adequate for the treatment of athletes in order to permit a safe and stable return to sports. The aim of this study was to report the results at 48 months of a series of athletes and the factors influencing the return to sports. Design Case series. A total of 140 athletes underwent a “one-step” BMDCT repair of OLT. All the patients had the cells harvested from the iliac crest, condensed and loaded on a scaffold, and then implanted. Patients were evaluated clinically by the American Orthopaedic Foot and Ankle Society (AOFAS) scores and Halasi score. Results AOFAS score improved from 58.7 ± 13.5 preoperatively to 90.6 ± 8.6 ( P < 0.005) at 24 months, and to 90.9 ± 10.7 at 48 months. Halasi score was 6.88 ± 1.8 preinjury, 4.08 ± 1.7 preoperatively, and 5.56 ± 2.0 at final follow-up. At the final follow-up, all the patients (beside 1 failure and 3 lost) were able to return to activity and 72.8% were able to resume sports at preinjury level. Conclusions “One-step” BMDCT repair of OLT had good clinical results that was durable over time in athletes, permitting a return to sports at preinjury level in the majority of patients. The preoperative presence of impingement and articular degeneration were the main negative prognostic factors.

Abstract INTRODUCTION Spinal cord stimulation is commonly used for neuropathic pain modulation. The major side effect is the onset of paresthesia. The authors describe a new stimulation design that suppresses pain as well as, or even better than, the currently used stimulation, but without creating paresthesia. METHODS A spinal cord electrode (Lamitrode) for neuropathic pain was implanted in 12 patients via laminectomy: 4 at the C2 level and 7 at the T8–T9 level for cervicobrachialgia and lumboischialgia, respectively (1 at T11 at another center). During external stimulation, the patients received the classic tonic stimulation (40 or 50 Hz) and the new burst stimulation (40-Hz burst with 5 spikes at 500 Hz per burst). RESULTS Pain scores were measured using a visual analog scale and the McGill Short Form preoperatively and during tonic and burst stimulation. Paresthesia was scored as present or not present. Burst stimulation was significantly better for pain suppression, by both the visual analog scale score and the McGill Short Form score. Paresthesia was present in 92% of patients during tonic stimulation, and in only 17% during burst stimulation. Average follow-up was 20.5 months. CONCLUSION The authors present a new method of spinal cord stimulation using bursts that suppress neuropathic pain without the mandatory paresthesia. Pain suppression seems as good as or potentially better than that achieved with the currently used stimulation. Average follow-up after nearly 2 years (20.5 months) suggests that this stimulation design is stable.
