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.

Background: Arthroscopic microfracture can effectively treat osteochondral lesions of the talus (OLTs). However, very few studies have reported on symptomatic improvement duration and time when symptomatic improvement ceases. This study aimed to investigate the clinical outcome changes after arthroscopic microfracture in patients with OLT. Methods: Among patients who underwent arthroscopic microfracture for OLT, 70 patients were available for follow-up for more than 3 years. Of these, 6 patients who showed worsening or no improvement in the 6 months after surgery were excluded, and a total of 64 patients were included in the analysis. To analyze and compare the clinical outcome changes according to time, the visual analog scale (VAS) and American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores were evaluated every 3 months up to 1 year postoperatively and every 1 year thereafter. The clinical outcome differences based on the lesion size, lesion location, lesion containment, presence of cyst and bone marrow edema, age, sex, and obesity were analyzed. Results: The preoperative and final follow-up VAS scores significantly improved from 6.2 ± 1.1 to 1.2 ± 1.1 ( P< .05) and the AOFAS score from 63.1 ± 7.3 to 91.0 ± 7.3 ( P< .05). The overall success rate for arthroscopic microfracture in this study was 88.6%. The postoperative VAS and AOFAS scores at 3, 6, 9, 12, 24, and 36 months were 3.7 ± 1.4, 2.5 ± 1.3, 2.0 ± 1.1, 1.6 ± 1.2, 1.2 ± 1.2, and 1.3 ± 1.2 and 74.7 ± 10.3, 80.5 ± 8.9, 84.3 ± 7.4, 88.3 ± 7.3, 91.1 ± 7.2, and 90.8 ± 7.5, respectively, showing significant improvements up to 2 years. After 2 years, the symptoms did not improve but were maintained at a certain level up to 3 years. No clinical outcome differences based on the lesion size, lesion containment, presence of cyst and bone marrow edema, age, sex, and obesity were observed. Conclusion: Symptomatic improvement early after arthroscopic microfracture for OLT was observed continuously for up to 2 years postoperatively. Symptom improvement was maintained without worsening for up to 3 years after surgery. Determining the final outcome of microfracture at least after 2 years would be reasonable. Level of Evidence: Level IV, case series.

Anterior Ankle Impingement

Objective To determine potential predictive associations between patient-/lesion-specific factors, clinical outcome and anterior ankle impingement in patients that underwent isolated autologous matrix-induced chondrogenesis (AMIC) for an osteochondral lesion of the talus (OLT). Design Thirty-five patients with a mean age of 34.7 ± 15 years who underwent isolated cartilage repair with AMIC for OLTs were evaluated at a mean follow-up of 4.5 ± 1.9 years. Patients completed AOFAS (American Orthopaedic Foot and Ankle Society) scores at final follow-up, as well as Tegner scores at final follow-up and retrospectively for preinjury and presurgery time points. Pearson correlation and multivariate regression models were used to distinguish associations between patient-/lesion-specific factors, the need for subsequent surgery due to anterior ankle impingement and patient-reported outcomes. Results At final follow-up, AOFAS and Tegner scores averaged 92.6 ± 8.3 and 5.1 ± 1.8, respectively. Both body mass index (BMI) and duration of symptoms were independent predictors for postoperative AOFAS and Δ preinjury to postsurgery Tegner with positive smoking status showing a trend toward worse AOFAS scores, but this did not reach statistical significance ( P = 0.054). Nine patients (25.7%) required subsequent surgery due to anterior ankle impingement. Smoking was the only factor that showed significant correlation with postoperative anterior ankle impingement with an odds ratio of 10.61 when adjusted for BMI and duration of symptoms (95% CI, 1.04-108.57; P = 0.047). Conclusion In particular, patients with normal BMI and chronic symptoms benefit from AMIC for the treatment of OLTs. Conversely, smoking cessation should be considered before AMIC due to the increased risk of subsequent surgery and possibly worse clinical outcome seen in active smokers.

Marrow Stimulation

Category: Ankle; Arthroscopy Introduction/Purpose: Bone marrow stimulation procedures, specifically microfracture, have become a common treatment technique for osteochondral lesions of the talus (OLT). Such procedures have been shown to be effective among a variety of patient populations at postoperative time points up to about 5 years (references?). While microfracture has been shown to be effective in short- to medium-term follow-up, there is a paucity of literature demonstrating the long-term efficacy of this procedure. Recently, the development of additional treatment techniques has been explored, with deterioration of the resultant fibrocartilage being a particular concern with microfracture. The purpose of this study is to determine the long-term effectiveness of microfracture bone marrow stimulation for treatment of OLTs in patients at least 10 years removed from surgery. Methods: A retrospective review of patients undergoing microfracture of an OLT with a single fellowship-trained orthopaedic foot and ankle surgeon at least 10 years prior was performed. Patients meeting the inclusion criteria were contacted to complete the Foot & Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) and Sports subscales, visual analog scale (VAS) for pain, as well as surveyed regarding their satisfaction with the outcome of the procedure using a 5-point Likert scale. In addition to medical chart review, patients were asked directly over the phone about any subsequent foot and ankle procedures needed, any injections necessary, and whether they wore an ankle brace/orthotic in the time following the procedure. Patient demographics including sex, age at time of surgery, laterality of surgery, and surgical history following their index procedure were reviewed. Descriptive statistics were calculated for patient demographics and survey responses to assess functional outcomes. Results: Forty-two patients were contacted and completed postoperative surveys. Average patient age at the time of the procedure was 38.6 years, and 24 patients (57%) were male. On average, FAAM-ADL score was 86.57 (+-20.85), Sports score was 72.31 (+-30.48), and VAS pain score was 19.52 (scale of 0-100). Patients reported being satisfied with the outcome of the procedure in 35 of 42 cases (83.3%). Five patients (11.9%) had other foot/ankle procedures since their microfracture, with 3 directly addressing the talus in some fashion. Three patients (7.1%) received injection(s) in their ankle in the follow-up period, and 9 patients (21.4%) reported wearing a brace since the time of surgery with 6 patients (14.3%) reporting it as a direct relation to their OLT and surgery. Conclusion: This study demonstrates that microfracture is an effective functional treatment for OLT in the long term, and addresses the valid questions posed about the ability for the procedure to produce durable fibrocartilage. Patients report average functional and pain assessment scores at the 10-year postoperative mark consistent with a generally successful and effective treatment.

Background: The treatment of symptomatic cartilage defects of the patella is particularly challenging, and no gold standard is currently available. Purpose: To evaluate the clinical results of a biphasic cell-free collagen-hydroxyapatite scaffold and to evaluate osteochondral tissue regeneration with magnetic resonance imaging (MRI). Study Design: Case series; Level of evidence, 4. Methods: Thirty-four patients (18 men and 16 women; mean ± SD: age, 30.0 ± 10 years) were treated by scaffold implantation for knee chondral or osteochondral lesions of the patella (area, 2.1 ± 1 cm2). The clinical evaluation was performed prospectively at 12 and 24 months via the IKDC (International Knee Documentation Committee; objective and subjective) and Tegner scores. MRI evaluation was performed at both follow-ups in 18 lesions through the MOCART score (magnetic resonance observation of cartilage repair tissue) and specific subchondral bone parameters. Results: A statistically significant improvement in all the scores was observed at 12- and 24-month follow-up as compared with the basal evaluation. The IKDC subjective score improved from 39.5 ± 14.5 to 61.9 ± 14.5 at 12 months ( P > .0005) with a further increase to 67.6 ± 17.4 at 24 months of follow-up (12-24 months, P = .020). The MRI evaluation showed a stable value of the MOCART score between 12 and 24 months, with a complete filling of the cartilage in 87.0% of the lesions, complete integration of the graft in 95.7%, and intact repair tissue surface in 69.6% at final follow-up. The presence of osteophytes or more extensive bony overgrowth was documented in 47.8% of the patients of this series, but no correlation was found between MRI findings and clinical outcome. Conclusion: The implantation of a cell-free collagen-hydroxyapatite osteochondral scaffold provided a clinical improvement at short-term follow-up for the treatment of patellar cartilage defects. Women had lower outcomes, and the need for realignment procedures led to a slower recovery. MRI evaluation showed some abnormal findings with the presence of bone overgrowth, but no correlation has been found with the clinical outcome.

Category: Ankle, Trauma Introduction/Purpose: Osteochondral lesions (OCL) are described as any defect involving both the articular surface and the subchondral bone of the talus. They are commonly associated with acute ankle injuries occurring often in active population. Bone marrow stimulation with microfracture is a standard reparative treatment for OCD however decline in related functional outcome has been reported. BST-CarGel contains chitosan which binds to negatively charged cartilage surface acting as biocompatible scaffold. This allows repair tissue with significant filling volume and proper integration into the surroundings. There has been reported better quantitative and qualitative cartilage repair tissue at 12 months with BST-CarGel. We first report on clinical results of bone marrow stimulation and BST-Cargel for recalcitrant talar OCL in patients previously treated with microfracture alone in a prospective study. Methods: This prospective single surgeon series was limited to patients with symptomatic OCL who previously had arthroscopic debridement and microfracture for same lesion. The pre-operative evaluation of all patients involved clinical assessment, weight bearing plain radiographs and magnetic resonance imaging of ankle joint. Inclusion criteria were age 18-55 years, single focal OCL of talus less than 3 cm2 and previous microfracture. Exclusion criteria was evidence of ankle osteoarthritis and allergy to chitosan or known hypersensitivity to crustaceans such as shrimp, lobster, and crab. Functional outcome assessment was measured using Foot and Ankle outcome score (FAOS) and EQ5D (Health related quality of life) pre and post-operatively. We used paired Student’s t-test for statistical analysis. Values for p < 0.05 were regarded as significant. The surgical technique used have been previously described in literature for OCL of the talus treated with bone marrow stimulation and Cargel. Results: There were fourteen patients who were treated with arthroscopic BST-Cargel with BMS and followed up prospectively. There was no loss to follow-up. The mean follow-up post-operatively was 28 months. There were eight males and six females in the study group. Patient mean age at the time of operation was 42 years (21–60 years). The mean size of talar OCL treated was 2.8 cm2 . Mean FAOS score for symptoms pre-operatively was 41.7 and post-operative was 52.8 (P<0.01). Mean FAOS pain subscale pre-operatively was 45.7 and post-operatively 55.6 (P<0.01). FAOS function and daily living score pre-operatively was 41.4 and post-operatively was 55.8 (P<0.01). Mean FAOS quality of life score was 39.2 pre-operatively and post-operative score 57.2 (P<0.01). EQ5D pre-operatively was 15 and post-operatively was 8 (P<0.01). Conclusion: We noted statistically significant improvement in each subscale of The Foot and Ankle Outcome questionnaire scores post-operatively. There was also significant improvement in generic health status instrument EQ-5D. We also noted talar OCL improvement on MRI scan taken pre and post BST-CarGel treatment. Recalcitrant OCL of talus present considerable challenge with persistent pain, functional limitations and secondary osteoarthritis. BST-Cargel treatment in our clinical study improved functional outcome scores similar to previously reported hip and knee studies. It requires standard arthroscopic technique and no complications were observed in our study.

Background: Arthroscopic microfracture for osteochondral lesions of the talus (OLT) has shown good functional outcomes. However, some studies have reported that functional outcomes deteriorate over time after surgery. Purpose: To use various functional scoring systems to evaluate functional outcomes in a large sample of patients with OLT treated by arthroscopic microfracture. Study Design: Case series; Level of evidence, 4. Methods: The study cohort consisted of 165 ankles (156 patients) that underwent arthroscopic microfracture for small to mid-sized OLT. The mean lesion size was 73 mm2 (range, 17-146 mm2), and the mean follow-up period was 6.7 years (range, 2.0-13.6 years). The Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale, visual analog scale (VAS) for pain, and 36-Item Short Form Health Survey (SF-36) were used to compare the functional outcomes between the preoperative and final follow-up assessments. Results: The mean FAOS significantly improved in regard to all subscores ( P < .001). The AOFAS ankle-hindfoot scale showed an improvement from 71.0 points (range, 47.0-84.0) preoperatively to 89.5 points (range, 63.0-100) at the final follow-up ( P < .001). The VAS score showed an improvement from 6.2 points (range, 4.0-9.0) preoperatively to 1.7 points (range, 0-6.0) at the final follow-up ( P < .001). The mean SF-36 score improved from 62.4 points (range, 27.4-76.6) preoperatively to 76.2 points (range, 42.1-98.0) at the final follow-up ( P < .001). Among 165 ankles, 22 ankles (13.3%) underwent repeat arthroscopic surgery for evaluation of repaired cartilage status. Conclusion: Arthroscopic microfracture showed good functional outcomes and improved quality of life with maintenance of satisfactory outcomes at a mean follow-up of 6.7 years. Therefore, arthroscopic microfracture seems to be reliable as a first-line treatment for OLT at an intermediate-term follow-up.

Category: Arthroscopy Introduction/Purpose: Bone marrow stimulation techniques, specifically arthroscopic microfracture, have become the therapy of choice for osteochondral lesions of the talus (OLTs) less than 15 mm2 in size. Traditionally, the microfracture site is protected with a postoperative non-weightbearing period of 6-8 weeks. However, recent research has suggested postoperative early weight bearing (EWB) after microfracture may produce outcomes equivalent to delayed weight bearing (DWB). We performed a prospective, randomized trial to determine whether the results of EWB after microfracture for OLTs are equivalent to DWB. Methods: We randomized 37 patients (37 ankles) undergoing arthroscopic microfracture for OLTs to either EWB or DWB protocols. The EWB cohort was allowed to bear weight as tolerated two weeks after surgery, while the DWB cohort was held non-weightbearing until six weeks postoperatively. We collected demographic data, mechanism of injury, lesion size and stage, Numeric Rating System pain scores (NRS), and American Academy of Orthopaedic Surgery Foot and Ankle Questionnaire (AAOS) functional scores preoperatively, then at 6 weeks, 3 months, 6 months, 1 year, and 2 years postoperatively. Results: There were no differences between the two cohorts in terms of patient age, mechanism of injury, lesion size, or lesion stage. The mean age at surgery was 34.1 years (range 21-50 years). 70.4% of the lesions were lateral, 22.2% were medial, and the remainder were central. The EWB group demonstrated statistically significant improvement in AAOS scores at the six week follow-up appointment. There were no significant AAOS score differences at the other time points. NRS pain scores were not significantly different at any time point. Both groups showed mild deterioration of results over time. Conclusion: Early weightbearing after microfracture for OLTs was associated with improved AAOS scores in the short term, without demonstrating poorer function or pain at 2 year follow up. This study supports early weightbearing after arthroscopic microfracture for osteochondral lesions of the talus.

Category: Arthroscopy Introduction/Purpose: With reported incidence rates ranging from 40% to 70% post ankle sprains and fractures, osteochondral lesions of the talus (OLT) are not uncommon. However, management of such defects remains challenging. Microfracturing is considered the standard treatment for symptomatic OLTs.Larger lesions however typically require more invasive restorative procedures such as autologous osteochondral transplantation. Microfracture results are variable due to the fact that the resulting reparative fibrocartilage is weaker and biomechanically inferior to native hyaline cartilage. In this study, we examine the functional and radiological outcomes following use of a new arthroscopic technique utilizing a mixture of micronized allograft cartilage matrix (BioCartilage) (Arthrex, Naples, FL) soaked in Bone Marrow Aspirate Concentrate (BMAC) to fill OLTs. Methods: Eighty-six consecutive patients treated for OLT using arthroscopic debridement and BioCartilage matrix soaked in BMAC were identified. All patients were treated by a single fellowship-trained sports medicine and foot and ankle surgeon. Functional outcomes were assessed using the Foot and Ankle Outcome Score (FAOS) and Patient-Reported Outcomes Measurement Information System (PROMIS). This information was obtained from a prospective registry at the authors’ institution. Wilcoxon signed rank tests were used to determine statistical significance between pre and postoperative clinical scores. Additionally, an attending radiologist assessed the reparative cartilage morphology on postoperative MRI scans. This was evaluated and scored using a modified magnetic resonance observation of cartilage tissue (MOCART) scoring system. Results: Thirty-one patients (19 Females; 12 Males) with a mean age of 37.8 years (Range 15–54) had a minimum follow-up duration of 12 months and were thus included in this review. Mean follow-up duration was 15.8 months (Range 12 –25.7). The mean patient BMI was 27.4 (Range 19.6 – 39.4), while the average osteochondral lesion size was 85.9 mm2 (Range 35 – 220). The Physical Function domain of the PROMIS score, demonstrated statistically significant change, improving from 40.63 ±8.31 to 48.31 ±10.07 (p=0.02). The Pain Intensity domain also improved significantly from 49.06 ±9.32 to 42.14 ±9.38 (p=0.03). The Pain Interference domain and FAOS scores did improve but not reaching statistical significance. The mean MRI MOCART score was 69 ±13.34 with 13.3 months average follow-up duration. Conclusion: Achieving the longest duration possible of symptom-free functioning postoperatively is the main goal of any cartilage repair procedure. Augmentation of an articular lesion’s infill with BioCartilage and BMAC may help enhance the biomechanical properties of the reparative fibrocartilage construct and its longevity. Our initial findings demonstrate favorable patient-reported outcomes. Moreover, postoperative MRIs demonstrate the majority of the lesions showed either complete or hypertrophic infill, complete or hypertrophic integration, homogenous repair tissue, and isointense signals. Long-term studies prospectively assessing the effectiveness of this technique in maintaining pain-free-function of the ankle joint are warranted.

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: Osteochondral lesions of the talus (OLT) are a common and challenging condition treated by the orthopedic foot and ankle surgeon. Multiple operative treatment modalities have been recommended, and there are several factors that need to be considered when devising a treatment plan. In this study, we retrospectively reviewed a group of patients treated operatively for osteochondral lesions of the talus to determine factors that may have affected outcome. Methods: A retrospective chart review of clinical, radiographic and operative records was performed for all patients treated for OLTs via marrow stimulation technique. All had a minimum followup of 6 months or until return to full activity, preoperative magnetic resonance imaging (MRI) of the OLT to determine size, and failure of nonoperative treatment. Results: A total of 130 patients were included in the study. This included 64 males and 66 females. The average patient age at the time of surgery was 35.1 ± 13.7 (range, 12 to 73) years. The average followup was 37.2 ± 40.2 (range, 7.43 to 247) weeks. The average size of the lesion was 0.84 ± 0.67 cm2. There were 20 lesions larger than 1.5 cm2 and 110 lesions smaller than 1.5 cm2. There were 113 contained lesions and 17 uncontained lesions. OLTs larger than 1.5 cm2 and uncontained lesions were associated with a poor clinical outcome. Conclusions: The treatment of osteochondral lesions of the talus remains a challenge to the foot and ankle surgeon. Arthroscopic debridement and drilling will often provide satisfactory results. However, larger lesions and uncontained lesions are often associated with inferior functional outcomes and may require a more extensive initial procedure.
