Meta-Analysis
PURPOSE
The objective of this study was to provide a comprehensive review of the existing literature regarding the treatment of osteochondral lesions of the talus (OLT) using autologous matrix-induced chondrogenesis (AMIC), while also discussing the mid-long term functional outcomes, complications, and surgical failure rate.
METHODS
We searched Embase, PubMed, and Web of Science for studies on OLT treated with AMIC with an average follow-up of at least 2 years. Publication information, patient data, functional scores, surgical failure rate, and complications were extracted.
RESULTS
A total of 15 studies were screened and included, with 12 case series selected for meta-analysis and 3 non-randomized controlled studies chosen for descriptive analysis. The improvements in the Visual Analog Scale (VAS), the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot, and Tegner scores at the last follow-up were (SMD = - 2.825, 95% CI - 3.343 to - 2.306, P < 0.001), (SMD = 2.73, 95% CI 1.60 to 3.86, P < 0.001), (SMD = 0.85, 95% CI 0.5 to 1.2, P < 0.001) respectively compared to preoperative values. The surgery failure rate was 11% (95% CI 8-15%), with a total of 12 patients experiencing complications.
CONCLUSION
The use of AMIC demonstrates a positive impact on pain management, functional improvement, and mobility enhancement in patients with OLT. It is worth noting that the choice of stent for AMIC, patient age, and OLT size can influence the ultimate clinical outcomes. This study provides evidences supporting the safety and efficacy of AMIC as a viable treatment option in real-world medical practice.

Review
Temporomandibular disorders (TMDs) are a heterogeneous group of musculoskeletal and neuromuscular conditions involving the temporomandibular joint (TMJ), masticatory muscles, and associated structures. Mesenchymal stromal/stem cells (MSCs) have emerged as a promising therapy for TMJ repair. This systematic review aims to consolidate findings from the preclinical animal studies evaluating MSC-based therapies, including MSCs, their secretome, and extracellular vesicles (EVs), for the treatment of TMJ cartilage/osteochondral defects and osteoarthritis (OA). Following the PRISMA guidelines, PubMed, Embase, Scopus, and Cochrane Library databases were searched for relevant studies. A total of 23 studies involving 125 , 149 , 470 , and 74 were identified. Compliance with the ARRIVE guidelines was evaluated for quality assessment, while the SYRCLE risk of bias tool was used to assess the risk of bias for the studies. Generally, MSC-based therapies demonstrated efficacy in TMJ repair across animal models of TMJ defects and OA. In most studies, animals treated with MSCs, their derived secretome, or EVs displayed improved morphological, histological, molecular, and behavioral pain outcomes, coupled with positive effects on cellular proliferation, migration, and matrix synthesis, as well as immunomodulation. However, unclear risk in bias and incomplete reporting highlight the need for standardized outcome measurements and reporting in future investigations.

Cartilage Apr 2024To systematically review the literature and analyze clinical outcomes and return-to-sport after surgical management of cartilage injuries in football players.
OBJECTIVE
To systematically review the literature and analyze clinical outcomes and return-to-sport after surgical management of cartilage injuries in football players.
DESIGN
A systematic literature review was performed in August 2023 on PubMed, WebOfScience, and Cochrane Library to collect studies on surgical strategies for cartilage lesions in football players. Methodological quality and risk of bias were assessed with the modified Coleman Methodology score and RoB2 and RoBANS2 tools.
RESULTS
Fifteen studies on 409 football players (86% men, 14% women) were included: nine prospective and two retrospective case series, one randomized controlled trial, one prospective comparative study, one case report, and one survey. Bone marrow stimulation (BMS) techniques were the most documented. The lesion size influenced the treatment choice: debridement was used for small lesions (1.1 cm), BMS, osteochondral autograft transplantation (OAT), matrix-assisted autologous chondrocytes transplantation (MACT), and scaffold-augmented BMS for small/mid-size lesions (2.2-3.0 cm), and autologous chondrocytes implantation (ACI) for larger lesions (5.8 cm). The surgical options yielded different results in terms of clinical outcome and return-to-sport, with fastest recovery for debridement and scaffold-augmented BMS. The current evidence is limited with large methodological quality variation (modified Coleman Methodology score 43.5/100) and a high risk of bias.
CONCLUSIONS
Decision-making in cartilage injuries seems to privilege early return-to-sport, making debridement and microfractures the most used techniques. The lesion size influences the treatment choice. However, the current evidence is limited. Further studies are needed to confirm these findings and establish a case-based approach to treat cartilage injuries in football players based on the specific patient and lesion characteristics and the treatments' potential in terms of both return-to-sport and long-term results.

Review
The damping system ensured by the osteochondral (OC) unit is essential to deploy the forces generated within load-bearing joints during locomotion, allowing furthermore low-friction sliding motion between bone segments. The OC unit is a multi-layer structure including articular cartilage, as well as subchondral and trabecular bone. The interplay between the OC tissues is essential in maintaining the joint functionality; altered loading patterns can trigger biological processes that could lead to degenerative joint diseases like osteoarthritis. Currently, no effective treatments are available to avoid degeneration beyond tissues' recovery capabilities. A thorough comprehension on the mechanical behaviour of the OC unit is essential to (i) soundly elucidate its overall response to intra-articular loads for developing diagnostic tools capable of detecting non-physiological strain levels, (ii) properly evaluate the efficacy of innovative treatments in restoring physiological strain levels, and (iii) optimize regenerative medicine approaches as potential and less-invasive alternatives to arthroplasty when irreversible damage has occurred. Therefore, the leading aim of this review was to provide an overview of the state-of-the-art-up to 2022-about the mechanical behaviour of the OC unit. A systematic search is performed, according to PRISMA standards, by focusing on studies that experimentally assess the human lower-limb joints' OC tissues. A multi-criteria decision-making method is proposed to quantitatively evaluate eligible studies, in order to highlight only the insights retrieved through sound and robust approaches. This review revealed that studies on human lower limbs are focusing on the knee and articular cartilage, while hip and trabecular bone studies are declining, and the ankle and subchondral bone are poorly investigated. Compression and indentation are the most common experimental techniques studying the mechanical behaviour of the OC tissues, with indentation also being able to provide information at the micro- and nanoscales. While a certain comparability among studies was highlighted, none of the identified testing protocols are currently recognised as standard for any of the OC tissues. The fibril-network-reinforced poro-viscoelastic constitutive model has become common for describing the response of the articular cartilage, while the models describing the mechanical behaviour of mineralised tissues are usually simpler (i.e., linear elastic, elasto-plastic). Most advanced studies have tested and modelled multiple tissues of the same OC unit but have done so individually rather than through integrated approaches. Therefore, efforts should be made in simultaneously evaluating the comprehensive response of the OC unit to intra-articular loads and the interplay between the OC tissues. In this regard, a multidisciplinary approach combining complementary techniques, e.g., full-field imaging, mechanical testing, and computational approaches, should be implemented and validated. Furthermore, the next challenge entails transferring this assessment to a non-invasive approach, allowing its application in vivo, in order to increase its diagnostic and prognostic potential.

Review
: Sever's disease, or calcaneal apophysitis, stands as the most prevalent cause of heel pain in children, often linked to sports like soccer, Australian football, and basketball. While various therapies are documented in the scientific literature, the standard choice is conservative treatment. Thus, the objective of this research was to assess the effectiveness of diverse conservative methods and techniques in alleviating Sever's disease symptoms. Systematic searches were conducted in October 2023 in PubMed, Web of Science, Scopus, SportDiscus, and PEDro, using terms like Osteochondritis, Osteochondrosis, Apophysitis, Sever's disease, Calcaneus, Adolescent, Child, and Childhood. The PEDro scale gauged methodological quality, and the Cochrane Risk of Bias tool evaluated the risk of bias. : Eight randomized controlled studies were included, featuring commonly used treatments such as insoles, therapeutic exercises, Kinesio taping, and foot orthoses. The methodological quality was generally good, with an average PEDro score of 6.75 points. Regarding bias, four articles had low risk, three had high risk, and one had some concern. Conservative treatment emerges as an effective option for alleviating symptoms associated with Sever's disease.

BACKGROUND
Retrograde drilling is an established surgical technique to treat osteochondral lesions of the talus (OLT). It involves non-trans-articular drilling to induce subchondral bone revascularization and bone formation without damaging the overlying articular cartilage. The present study aimed to elucidate the heterogeneity of clinical studies on retrograde drilling for OLT.
DESIGN
A systematic search of the MEDLINE, Web of Science, EMBASE, and Cochrane Library databases for studies published between January 1996 and August 27, 2022, was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by two independent reviewers. The included studies were evaluated for their level of evidence (LoE) and quality of evidence (QoE) using the Modified Coleman Methodology Score. Variables reporting surgical and clinical outcomes and complications were evaluated.
RESULTS
Eleven studies with 207 ankles were included (mean follow-up period = 31.1 months). The mean LoE was 3.8 (LoE 3: two studies, LoE 4: nine studies), and the mean QoE was 50.8 (fair: three studies, poor: eight studies). Ten studies used the American Orthopedic Foot and Ankle Society (AOFAS) score, which improved from 57.9 preoperatively to 86.1 postoperatively. The period and protocol of conservative treatment, lesion character, surgical technique, and postoperative protocol were inconsistent or underreported.
CONCLUSIONS
This systematic review revealed that low LoE and poor QoE, coupled with heterogeneity among the included studies, impede definitive conclusions regarding the effectiveness of this technique. Consequently, well-designed clinical trials are essential to develop standardized clinical guidelines for using retrograde drilling in OLT.

Review
PURPOSE
Various surgical treatments have been described for the treatment of reverse Hill-Sachs lesions (rHSls) sized between 20% and 50% in the case of posterior shoulder dislocation. The aim of this systematic review is to report the clinical and radiological outcomes of subscapularis or lesser tuberosity transfer (McLaughlin and modified procedures) compared to bone or osteochondral autograft or allograft.
METHODS
A systematic review was performed on five medical databases up to December 2022. The inclusion criteria were clinical studies of all levels of evidence describing clinical or radiological outcomes of either procedure. The assessment of the quality of evidence was performed with the Modified Coleman Score.
RESULTS
A total of 14 studies (five prospective and nine retrospective) were included. A total of 153 patients (155 shoulders, 78.4% male) with a mean age of 37.2 (22-79) years were reviewed at an average follow-up of 53.1 (7.1-294) months. No relevant difference was found for the clinical scores, range of motion, complications and redislocation rate between the two treatments. Radiological osteoarthritis (OA) was reported in 11% (10/87) in the McLaughlin group and in 21% (16/73) in the humeral reconstruction group.
CONCLUSIONS
McLaughlin and anatomic humeral reconstruction lead to similar satisfactory clinical results and a low redislocation rate in the treatment of rHSls. Anatomic humeral reconstruction seems associated with an increased risk of OA progression.

Review
BACKGROUND
Osteochondritis dissecans (OCD) of the capitellum is a well-described condition that most commonly affects adolescent throwing athletes and gymnasts. There is no gold standard rehabilitation protocol or timing for return to sport (RTS) after surgical management of OCD of the capitellum.
HYPOTHESIS/PURPOSE
The purpose of the study was to identify in the existing literature any criteria used for RTS following surgical treatment of OCD of the capitellum. The hypothesis was that surgeons would utilize length of time rather than functional criteria or performance benchmarks for RTS.
METHODS
Level 1 to 4 studies evaluating athletes who underwent surgery for OCD of the capitellum with a minimum follow-up of 1-year were included. Studies not describing RTS criteria, including less than 1-year follow-up, non-operative management only, and revision procedures were excluded. Each study was analyzed for RTS criteria, RTS rate, RTS timeline, sport played, level of competition, graft source (if utilized), and postoperative rehabilitation parameters. Assessment of bias and methodological quality was performed using the Coleman methodology score and RTS value assessment.
RESULTS
All studies reported a rehabilitation protocol with immobilization followed by bracing with progressive range of motion. RTS rate was 80.9% (233/288). The majority of studies reported using time-based criteria for RTS (11/15). The most commonly reported timeline was 6 months (range: 3-12 months).
CONCLUSION
The overall RTS rate after surgical treatment of capitellar OCD is high with no consensus on RTS criteria. The two most consistent RTS criteria reported in the literature are return of elbow range of motion and healing demonstrated on postoperative imaging. There is a wide range of time to RTS in the literature, which may be sport dependent. Further research is needed to develop functional and performance-based metrics to better standardize RTS criteria and rehabilitation protocols.

OBJECTIVE
Uniformity of reporting is a requisite to be able to compare results of clinical studies on the treatment of osteochondral lesions of the talus (OLT). The primary aim of this study was to evaluate the frequency and quality of reporting of size, morphology, and location of OLTs.
DESIGN
A literature search was performed from 1996 to 2023 to identify clinical studies on surgical treatment of OLTs. Screening was performed by 2 reviewers, who subsequently graded the quality using the methodological index for non-randomized studies (MINORS). The primary outcome was the frequency and qualitative assessment of reporting of size, morphology, and location.
RESULTS
Of 3,074 articles, 262 articles were included. This comprised a total of 11,785 patients. Size was reported in 248 (95%) of the articles and was described with a measure for surface area in 83%, however, in 56%, definition of measurement is unknown. Intraclass coefficient (ICC) value for the reliability of size measurement was 0.94 for computed tomography (CT) scan and 0.87 for MRI scan. Morphology was reported in 172 (66%) of the articles and using a classification system in 23% of the studies. Location was reported in 220 (84%) of the studies.
CONCLUSION
No consensus was found on the reporting of morphology, with non-validated classification systems and different terminologies used. For location, reporting in 9 zones is underreported. Size was well reported and measurements are more reliable for CT compared with MRI. As these prognostic factors guide clinical decision-making, we advocate the development of a standardized and validated OLT classification to reach uniform reporting in literature.

Orthopaedic Journal of Sports Medicine Feb 2024Limited literature is available regarding the effect of subchondral cysts on the surgical outcomes for treatment of osteochondral lesion of the talus (OLT).
BACKGROUND
Limited literature is available regarding the effect of subchondral cysts on the surgical outcomes for treatment of osteochondral lesion of the talus (OLT).
PURPOSE
To conduct a systematic review and meta-analysis of studies comparing surgical outcomes between OLTs with and without cysts.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, the authors searched PubMed, Embase, Web of Science, and the Cochrane Library for relevant studies published up to January 7, 2023. The 4375 retrieved studies were screened, and 9 articles (level of evidence, 2-4) were included, which comprised 165 patients with OLT and subchondral cysts (cyst group) and 223 without cysts (noncyst group). After data extraction, mean differences in outcome scores (American Orthopaedic Foot and Ankle Society [AOFAS] Ankle Hindfoot Scale, visual analog scale [VAS] score for pain) and adverse events were compared between the groups.
RESULTS
Functional scores improved after surgery in both groups, with the cyst group having a significantly higher AOFAS score than the noncyst group ( = .005; = 0%); subgroup analysis revealed that this difference was attributable to the size of the osteochondral lesion and the type of surgical procedure. No significant difference was found between the cyst and noncyst groups in VAS pain scores ( = .77; = 0%) or postoperative adverse events ( = .35; = 0%).
CONCLUSION
The results of this review indicated that patients with subchondral cysts improved with surgical treatment of OLT. A relatively low level of evidence was available to indicate that surgical treatment for small OLTs with subchondral cysts will result in better clinical outcomes compared with OLTs without cysts.
