Abstract
Osteochondral defects are caused by injury to both the articular cartilage and subchondral bone within skeletal joints. They can lead to irreversible joint damage and increase the risk of progression to osteoarthritis. Current treatments for osteochondral injuries are not curative and only target symptoms, highlighting the need for a tissue engineering solution. Scaffold-based approaches can be used to assist osteochondral tissue regeneration, where biomaterials tailored to the properties of cartilage and bone are used to restore the defect and minimise the risk of further joint degeneration. This review captures original research studies published since 2015, on multiphasic scaffolds used to treat osteochondral defects in animal models. These studies used an extensive range of biomaterials for scaffold fabrication, consisting mainly of natural and synthetic polymers. Different methods were used to create multiphasic scaffold designs, including by integrating or fabricating multiple layers, creating gradients, or through the addition of factors such as minerals, growth factors, and cells. The studies used a variety of animals to model osteochondral defects, where rabbits were the most commonly chosen and the vast majority of studies reported small rather than large animal models. The few available clinical studies reporting cell-free scaffolds have shown promising early-stage results in osteochondral repair, but long-term follow-up is necessary to demonstrate consistency in defect restoration. Overall, preclinical studies of multiphasic scaffolds show favourable results in simultaneously regenerating cartilage and bone in animal models of osteochondral defects, suggesting that biomaterials-based tissue engineering strategies may be a promising solution.

The Frequency and Severity of Complications in Surgical Treatment of Osteochondral Lesions of the Talus: A Systematic Review and Meta-Analysis of 6,962 Lesions. Cartilage 2023; 14:180-197. [PMID: 37144397 PMCID: PMC10416205 DOI: 10.1177/19476035231154746] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 01/18/2023] [Accepted: 01/18/2023] [Indexed: 05/06/2023] Open
Abstract
OBJECTIVE The primary aim was to determine and compare the complication rate of different surgical treatment options for osteochondral lesions of the talus (OLTs). The secondary aim was to analyze and compare the severity and types of complications. DESIGN A literature search was performed in MEDLINE (PubMed), EMBASE (Ovid), and the Cochrane Library. Methodological quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS). Primary outcome was the complication rate per surgical treatment option. Secondary outcomes included the severity (using the Modified Clavien-Dindo-Sink Complication Classification System for Orthopedic Surgery) and types of complications. The primary outcome, the severity, and the sub-analyses were analyzed using a random effects model. A moderator test for subgroup-analysis was used to determine differences. The types of complications were presented as rates. RESULTS In all, 178 articles from the literature search were included for analysis, comprising 6,962 OLTs with a pooled mean age of 35.5 years and follow-up of 46.3 months. Methodological quality was fair. The overall complication rate was 5% (4%-6%; treatment group effect, P = 0.0015). Analysis resulted in rates from 3% (2%-4%) for matrix-assisted bone marrow stimulation to 15% (5%-35%) for metal implants. Nerve injury was the most observed complication. CONCLUSIONS In 1 out of 20 patients treated surgically for an OLT, a complication occurs. Metal implants have a significantly higher complication rate compared with other treatment modalities. No life-threatening complications were reported.

Abstract
This systematic review aimed to summarize the full range of complications reported following ankle arthroscopy and the frequency at which they occur. A computer-based search was performed in PubMed, Embase, Emcare, and ISI Web of Science. Two-stage title/abstract and full-text screening was performed independently by two reviewers. English-language original research studies reporting perioperative complications in a cohort of at least ten patients undergoing ankle arthroscopy were included. Complications were pooled across included studies in order to derive an overall complication rate. Quality assessment was performed using the Oxford Centre for Evidence-Based Medicine levels of evidence classification. A total of 150 studies describing 7,942 cases of ankle arthroscopy in 7,777 patients were included. The overall pooled complication rate was 325/7,942 (4.09%). The most common complication was neurological injury, accounting for 180/325 (55.4%) of all complications. Of these, 59 (32.7%) affected the superficial peroneal nerve. Overall, 36/180 (20%) of all nerve injuries were permanent. The overall complication rate following anterior ankle arthroscopy was 205/4,709 (4.35%) compared to a rate of 35/528 (6.6%) following posterior arthroscopy. Neurological injury occurred in 52/1,998 (2.6%) of anterior cases using distraction, compared to 59/2,711 (2.2%) in cases with no distraction. The overall rate of major complications was 16/7,942 (0.2%), with the most common major complication - deep vein thrombosis - occurring in five cases. This comprehensive systematic review demonstrates that ankle arthroscopy is a safe procedure with a low overall complication rate. The majority of complications are minor, with potentially life-threatening complications reported in only 0.2% of patients.

Abstract
Purpose
Operative treatment of talar osteochondral lesions is challenging with various treatment options. The aims were (i) to compare patient populations between the different treatment options in terms of demographic data and lesion size and (ii) to correlate the outcome with demographic parameters and preoperative scores.
Methods
A systemic review was conducted according to the PRISMA guidelines. The electronic databases Pubmed (MEDLINE) and Embase were screened for reports with the following inclusion criteria: minimum 2-year follow-up after operative treatment of a talar osteochondral lesion in at least ten adult patients and published between 2000 and 2020.
Results
Forty-five papers were included. Small lesions were treated using BMS, while large lesions with ACI. There was no difference in age between the treatment groups. There was a correlation between preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score and change in AOFAS score (R = −0.849, P < 0.001) as well as AOFAS score at follow-up (R = 0.421, P = 0.008). Preoperative size of the cartilage lesion correlates with preoperative AOFAS scores (R= −0.634, P = 0.001) and with change in AOFAS score (R = 0.656, P < 0.001) but not with AOFAS score at follow-up. Due to the heterogeneity of the studies, a comparison of the outcome between the different operative techniques was not possible.
Conclusion
Patient groups with bigger lesions and inferior preoperative scores did improve the most after surgery.

Abstract
Background: Magnetic resonance imaging (MRI) is commonly used for evaluation of ankle cartilage repair, yet its association with clinical outcome is controversial. This study analyzes the correlation between MRI and clinical outcome after cartilage repair of the talus including bone marrow stimulation, cell-based techniques, as well as restoration with allo- or autografting. Methods: A systematic search was performed in MEDLINE, Embase, and Cochrane Collaboration. Articles were screened for correlation of MRI and clinical outcome. Guidelines of Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) were used. Chi-square test and regression analysis were performed to identify variables that determine correlation between clinical and radiologic outcome. Results: Of 2687 articles, a total of 43 studies (total 1212 cases) were included with a mean Coleman score of 57 (range, 33-70). Overall, 93% were case series, and 5% were retrospective and 2% prospective cohort studies. Associations between clinical outcome and ≥1 imaging variable were found in 21 studies (49%). Of 24 studies (56%) using the composite magnetic resonance observation of cartilage repair tissue (MOCART) score, 7 (29%) reported a correlation of the composite score with clinical outcome. Defect fill was associated with clinical outcome in 5 studies (12%), and 5 studies (50%) reported a correlation of T2 mapping and clinical outcome. Advanced age, shorter follow-up, and larger study size were associated with established correlation between clinical and radiographic outcome (P = .021, P = .028, and P = .033). Conclusion: Interpreting MRI in prediction of clinical outcome in ankle cartilage repair remains challenging; however, it seems to hold some value in reflecting clinical outcome in patients with advanced age and/or at a shorter follow-up. Yet, further research is warranted to optimize postoperative MRI protocols and assessments allowing for a more comprehensive repair tissue evaluation, which eventually reflect clinical outcome in patients after cartilage repair of the ankle. Level of Evidence: Level III, systematic review and meta-analysis.

Abstract
The aim of this meta-analysis was to compare the efficacy and safety between the microfracture (MFx) and augmented microfracture (MFx+) techniques for articular cartilage defects of the talus (OLTs). PubMed and EMBASE were searched from January 1950 to October 2020. Only randomized controlled trials, quasi-randomized controlled trials, and observational studies (retrospective and prospective) applying MFx and MFx+ techniques to treat talar cartilage defects were selected. Ten trials with 492 patients were included. There was significant difference in final American Orthopaedic Foot & Ankle Society score (AOFAS) (mean difference [MD] = 7.07; 95% confidence interval [CI], 3.70-10.44; p < .01), AOFAS change (MD = 7.97; 95% CI, 4.27-11.66; p < .01), visual analog scale (VAS) change score (MD = 0.44; 95% CI, 0.29-0.59; p < .01), Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score (MD = 12.51; 95% CI, 7.16-17.86; p < .01), complication (RR = 0.33; 95% CI, 0.16-0.69; p < .01), and revision (Relative risk = 0.34; 95% CI, 0.15-0.77; p < .05), between the MFx and MFx+ groups. No significant difference was observed for final VAS pain score (MD = -0.53; 95% CI, -1.2 to 1.05; p = .13) and Tegner scale (MD = 0.31; 95% CI, -1.05 to 1.66; p = .66) in either group. Our results suggest that augmented microfracture is superior to microfracture alone in the treatment of talar OLTs based on the AOFAS, MOCART, VAS score, complication rate, and revision ratio. Therefore, microfracture with augmentation should be considered as a treatment for OLTs of talus. However, more randomized trials are still required to determine the long-term superiority of MFx+.

Abstract
PURPOSE To compare the results of bone marrow stimulation (BMS) versus autologous osteochondral transfer (AOT) as primary surgical option for large cystic osteochondral lesion of talus (OLT) and to further distinguish factors associated with clinical failures and overall survival. METHODS We retrospectively analyzed patients with symptomatic large cystic OLT (>300 mm3) who underwent either primary BMS or AOT between January 2001 and January 2016 with a minimum follow-up of 36 months. Lesion surface area and volume were measured on magnetic resonance imaging. Clinical outcomes were assessed using pain visual analog scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, and Foot and Ankle Outcome Score (FAOS). Survival outcomes and factors associated with clinical failures were evaluated using Kaplan-Meier analysis and Cox regression analyses, respectively. RESULTS Fifty of the total 853 patients had large cystic OLTs. Thirty-two patients underwent primary BMS, and 18 patients underwent primary AOT. Mean follow-up period was 118 months, and average lesion surface area and volume were 152.8 mm2 and 850.7 mm3, respectively. The primary AOT group showed significantly superior improvements in clinical outcomes compared with the BMS group at last follow-up (P = .001). Fourteen patients in the primary BMS group and 2 patients in the primary AOT group experienced clinical failure. Kaplan-Meier analysis showed a superior survival rate of primary AOT (P = .042). Syndesmosis widening (hazard ratio 12.361; P = .004) and large lesion surface area (hazard ratio 1.011; P = .014) were significant relative risks of clinical failure in the primary BMS group. However, lesion volume showed no significant relationship with clinical failure. CONCLUSION Long-term results of primary AOT showed superior clinical improvements and survival rate in treating large cystic OLT. Risk factors for failure in the primary BMS group were large lesion surface area and syndesmosis widening. STUDY DESIGN Retrospective comparative study LEVEL OF EVIDENCE: III.

Abstract
Introduction: The use of orthobiologics as supplemental treatment for foot and ankle pathologies have increased in the past decades. They have been used to improve the healing of bone and soft tissue injuries. There have been several studies that examined the use of biologics for knee and hip pathologies but the foot and ankle construct has unique features that must be considered.Areas covered: The biologics for foot and ankle injuries that are covered in this review are platelet-rich plasma (PRP), stem cells, growth factors, hyaluronic acid, bone grafts, bone substitutes, and scaffolds. These modalities are used in the treatment of pathologies related to tendon and soft tissue as well as cartilage.Expert opinion: The utilization of biological adjuncts for improved repair and regeneration of ankle injuries represents a promising future in our efforts to address difficult clinical problems. The application of concentrated bone marrow and PRP each represents the most widely studied and commonly used injection therapies with early clinical studies demonstrating promising results, research is also being done using other potential therapies such as stem cells and growth factors; further investigation and outcome data are still needed.

Abstract
BACKGROUND The aim of this study was to compare the clinical and magnetic resonance imaging (MRI) outcomes of arthroscopic microfracture (MF) plus chitosan-glycerol phosphate/blood implant and MF alone for the treatment of the osteochondral lesions of the talus (OCLTs). METHODS Patients who underwent either MF plus chitosan (group 1, n = 32) or MF alone (group 2, n = 31) between 2015 and 2019 in 2 separate time periods were retrospectively analyzed. Visual analog scale (VAS) score and American Orthopaedic Foot & Ankle Society (AOFAS) score were used for clinical evaluation. The magnetic resonance observation of cartilage repair tissue (MOCART) system was used for MRI evaluation. The mean follow-up time was 32 ± 13 months (range, 12-61 months). RESULTS Postoperatively, we detected significant improvements in both groups in terms of VAS and AOFAS scores. However, we observed no statistically significant difference between groups in terms of clinical scores, except the mean VAS function score, which was significantly higher in group 1 (P = .022). According to MOCART scale, complete repair with the filling of the chondral defect and intactness of the surface of the repair tissue were more common in group 1. However, these parameters did not significantly differ between groups (P = .257 and .242, respectively). CONCLUSION Arthroscopic MF plus chitosan glycerol phosphate/blood implant did not result in better clinical and MRI outcomes compared with MF alone in the treatment of OCLTs.

Abstract
BACKGROUND The aim of this study was to evaluate the clinical and radiologic results of 2 different scaffolds with hyaluronan or chitosan-based structure used in the treatment of talus osteochondral lesions. METHODS Eighty-one patients who underwent chondral lesion repair with hyaluronan (n = 42) or chitosan-based (n = 39) scaffold were included. American Orthopaedic Foot & Ankle Society (AOFAS) and visual analog scale (VAS) scores were evaluated within and between groups preoperatively and at the 3rd, 12th, and 24th month postoperatively. In all patients, magnetic resonance imaging was performed between the 12 and 18th month postoperatively and compared with magnetic resonance observation of cartilage repair tissue (MOCART) scoring. RESULTS Within-group evaluations revealed significant improvements in AOFAS and VAS scores at postoperative 3 and 12 months. The postoperative 24th-month results of AOFAS scores in any group did not differ significantly from the 12th-month results. There was no significant difference between the groups in comparison of AOFAS, VAS, and MOCART scores at any time period. CONCLUSION Both scaffolds were found to be effective in cartilage healing but had no clinical or radiologic superiority to each other. This is the first study to compare the use of different cell-free scaffold types in osteochondral defects of the talus. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Clinical Outcomes of Osteochondral Lesions of the Talus With Large Subchondral Cysts Treated With Osteotomy and Autologous Chondral Grafts: Minimum 2-Year Follow-up and Second-Look Evaluation. Orthop J Sports Med 2020; 8:2325967120937798. [PMID: 32782905 PMCID: PMC7388127 DOI: 10.1177/2325967120937798] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Accepted: 03/12/2020] [Indexed: 11/20/2022] Open
Abstract
Background: Osteochondral lesions of the talus (OLTs) with large subchondral cysts are
challenging to treat. Purpose: To determine the safety and efficacy of autologous chondral grafting and
malleolus osteotomy for treating OLTs associated with large subchondral
cysts. Study Design: Case series; Level of evidence, 4. Methods: A total of 19 patients underwent autologous chondral grafting and malleolus
osteotomy. We obtained the visual analog scale (VAS), American Orthopaedic
Foot and Ankle Society (AOFAS) ankle-hindfoot, and magnetic resonance
observation of cartilage repair tissue (MOCART) scores at 1 and 2 years
postoperatively. The International Cartilage Repair Society (ICRS) score was
collected 2 years postoperatively during second-look arthroscopic
surgery. Results: In all patients, the osteotomy site healed without nonunion or malunion. Only
1 patient developed joint space narrowing. No donor site complications
occurred. The mean AOFAS score significantly improved at 1 year (from 72.8 ±
4.8 preoperatively to 93.7 ± 4.6; t = –13.708;
P < .0001). The 1- and 2-year AOFAS scores were
similar (t = –0.755; P = .455), indicating
stable improvement. The mean VAS score significantly decreased at 1 year
(from 4.68 ± 0.67 preoperatively to 0.47 ± 0.69; t =
18.974; P < .0001). The 1- and 2-year VAS scores were
similar (t = –0.705; P = .455), as were
the 1- and 2-year MOCART scores (64.2 ± 7.5 vs 67.4 ± 7.3, respectively;
t = –1.312; P = .198). The ICRS scores
were as follows: 7 points (abnormal) in 1 (5.2%) patient, 8 to 11 points
(nearly normal) in 9 (47.4%) patients, and 12 points (normal) in 9 (47.4%)
patients. Conclusion: Osteotomy combined with autologous osteochondral transplantation provided
good functional outcomes in patients with OLTs and large subchondral cysts.
Second-look arthroscopic surgery showed healthy cartilage healing.

Abstract
INTRODUCTION Large cystic osteochondral lesions of the talus (OLTs) have been shown to have inferior clinical outcomes after reparative techniques such as bone marrow stimulation. Autologous osteochondral transplantation has been viewed as an alternative choice for treating these lesions, but donor-site morbidity has limited its application. Excellent clinical outcomes have been shown in repairing these types of lesions with autologous osteoperiosteal grafts, and these outcomes are achieved at a low cost and without donor-site morbidity in the normal knee joint. This will be the first randomised controlled trial to compare the two surgical techniques, and recommendations for the treatment of patients with large cystic OLTs will be provided. METHODS AND ANALYSIS A non-inferiority randomised controlled trial will be conducted. A total of 70 participants with clinically diagnosed large cystic OLTs will be randomly allocated to either the experimental group or the control group at a ratio of 1:1. The experimental group will be treated with autologous osteoperiosteal cylinder graft transplantation, while the control group will be treated with autologous osteochondral transplantation. The primary outcome measure will be the American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score and the Short Form 12 (SF-12) questionnaire. Secondary outcome measures will include the secondary arthroscopy International Cartilage Repair Society score, the Magnetic Resonance Observation of Cartilage Repair Tissue score, the Tegner activity level score, the visual analogue scale, routine X-rays, CT and complications. These parameters will be evaluated preoperatively, as well as at 3, 6, 12, 24, 36 and 60 months postoperatively. In this trial, we hypothesised that both procedures offer good results for the treatment of patients with large cystic OLTs, and occurrence of donor-site morbidity in autologous osteoperiosteal cylinder graft transplantation group is less than that in autologous osteochondral transplantation group. ETHICS AND DISSEMINATION The current study was approved by the board of research ethics of Peking University Third Hospital Medical Science Research Ethics Committee. The results of this study will be presented at national and international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT03347877.

Abstract
PURPOSE OF REVIEW The use of biologics in orthopedics is becoming increasingly popular as an adjuvant in healing musculoskeletal injuries. Though many biologics involved in the management of foot and ankle injuries are used based on physician preference, reports of improved outcomes when combined with standard operative treatment has led to further clinical interest especially in foot and ankle trauma. RECENT FINDINGS The most recent studies have shown benefits for biologic use in patients predisposed to poor bone and soft tissue healing. Biologics have shown benefit in treating soft tissue injuries such as Achilles ruptures as well as the complications of trauma such as non-unions and osteoarthritis. Biologics have shown some benefit in improving functional and pain scores, as well as reducing time to heal in foot and ankle traumatic injuries, with particular success shown with patients that have risk factors for poor healing. As the use of biologics continues to increase, there is a need for high-level studies to confirm early findings of lower level reports.
