Investigation of the efficacy of epidermal growth factor, boric acid and their combination in cartilage injury in rats: An experimental study. Jt Dis Relat Surg 2024; 35:156-168. [PMID: 38108177 PMCID: PMC10746896 DOI: 10.52312/jdrs.2023.1074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 09/15/2023] [Indexed: 12/19/2023] Open
Abstract
OBJECTIVES In this study, we aimed to determine the bioefficacy of epidermal growth factor (EGF), boric acid (BA), and their combination on cartilage injury in rats. MATERIALS AND METHODS In in vitro setting, the cytotoxic effects of BA, EGF, and their combinations using mouse fibroblast cell (L929), human bone osteosarcoma cell (Saos-2), and human adipose derived mesenchymal stem cells (hAD-MSCs) were determined by applying MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] test. In in vivo setting, 72 rats were randomly divided into four groups. A standard chondral defect was created and microfracture was performed in all groups. Group A was determined as the control group. In addition to the standard procedure, Group B received 100 ng/mL of EGF, Group C received a combination of 100 ng/mL of EGF and 10 µg/mL of BA combination, and Group D 20 µg/mL of BA. RESULTS The cytotoxic effect of the combinations of EGF dilutions (1, 5, 10, 25, 50, 100, 200 ng/mL) with BA (100, 300, 500 µg/mL) was observed only in the 72-h application period and in Saos-2. The cytotoxic effect of BA was reduced when combined with EGF. There was no significant difference in the histopathological scores among the groups (p=0.13). CONCLUSION Our study showed that EGF and low-dose BA application had a positive effect on cartilage healing in rats. Significant decreases in recovery scores were observed in the other groups. The combination of EGF and BA promoted osteoblast growth. Detection of lytic lesions in the group treated with 20 µg/mL of BA indicates that BA may have a cytotoxic effect.

Stromal Vascular Fraction Therapy for Knee Osteoarthritis: A Systematic Review. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:2090. [PMID: 38138193 PMCID: PMC10744886 DOI: 10.3390/medicina59122090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 11/22/2023] [Accepted: 11/26/2023] [Indexed: 12/24/2023]
Abstract
Background and Objectives: Knee osteoarthritis (OA) is a widespread joint disease, set to increase due to aging and rising obesity. Beyond cartilage degeneration, OA involves the entire joint, including the synovial fluid, bones, and surrounding muscles. Existing treatments, such as NSAIDs and corticosteroid injections, mainly alleviate symptoms but can have complications. Joint replacement surgeries are definitive but carry surgical risks and are not suitable for all. Stromal vascular fraction (SVF) therapy is a regenerative approach using cells from a patient's adipose tissue. SVF addresses as degenerative and inflammatory aspects, with potential for cartilage formation and tissue regeneration. Unlike traditional treatments, SVF may reverse OA changes. Being autologous, it reduces immunogenic risks. Materials and Methods: A systematic search was undertaken across PubMed, Medline, and Scopus for relevant studies published from 2017 to 2023. Keywords included "SVF", "Knee Osteoarthritis", and "Regenerative Medicine". Results: This systematic search yielded a total of 172 articles. After the removal of duplicates and an initial title and abstract screening, 94 full-text articles were assessed for eligibility. Of these, 22 studies met the inclusion criteria and were subsequently included in this review. Conclusions: This review of SVF therapy for knee OA suggests its potential therapeutic benefits. Most studies confirmed its safety and efficacy, and showed improved clinical outcomes and minimal adverse events. However, differences in study designs and sizes require a careful interpretation of the results. While evidence supports SVF's positive effects, understanding methodological limitations is key. Incorporating SVF is promising, but the approach should prioritize patient safety and rigorous research.

Mid-term results of autologous matrix-induced chondrogenesis surgery with or without scaffolds for arthroscopic treatment of deep talus osteochondral lesions: A comparative study. Jt Dis Relat Surg 2023; 34:613-619. [PMID: 37750266 PMCID: PMC10546858 DOI: 10.52312/jdrs.2023.1197] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 08/04/2023] [Indexed: 09/27/2023] Open
Abstract
OBJECTIVES This study aims to investigate the effectiveness of arthroscopic autologous matrix-induced chondrogenesis (AMIC) procedure with or without polyglycolic acid-hyaluronic acid (PGA-HA)-based cell-free scaffold (CFS) in Bristol Stage 4 and Stage 5 osteochondral lesion of the talus (OLT) ranging between 1.5 and 3 cm2 . PATIENTS AND METHODS Between March 2018 and March 2021, a total of 47 patients with OLTs (29 males, 18 females; mean age: 22.8±2.3 years; range, 18 to 65 years) were retrospectively analyzed. The patients were divided into two groups based on the procedures applied. Patients in the first group (Group 1, n=23) underwent the AMIC procedure alone (curettage, microfracture, and grafting), while patients in the second group (Group 2, n=24) underwent AMIC procedure with PGA-HA-based CFS. The localization of the lesions was evaluated. All OLTs were diagnosed with preoperative radiography and magnetic resonance imaging (MRI). During the preoperative period, lesion stages were evaluated based on the Bristol staging system, and the postoperative results were evaluated based on the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scoring system. RESULTS The mean follow-up was 36.2±5.6 months. In the early period, the three-month functional scores were comparable between the groups. While a significant increase was observed in the American Orthopaedic Foot and Ankle Society (AOFAS) scores from the mean preoperative of 62.71±4.44 points to the postoperative of 86.00±6.58 points in Group 1, a significant increase in the AOFAS score was observed from 65.28±7.91 points to 95.42±4.41 points in Group 2 at 12-month follow-up (p=0.016, p=0.011, respectively). The functional scores tended to progress after 12 months. Radiologically, a complete defect filling was observed in a mean of 10.5±2.7 months. No graft hypertrophy was recorded in any patients. The AOFAS and MOCART scores in Group 2 were found to be statistically significantly higher than that in Group 1 (p=0.034 for AOFAS 1/AOFAS 2 and p=0.006 for MOCART 1/MOCART 2). Overall, there was a positive, but weak, significant correlation between the final AOFAS scores and MOCART scores (r=0.347, p<0.001). CONCLUSION Arthroscopic AMIC procedure in deep OLTs between 1.5 cm2 and 3 cm2 can yield a statistically significant improvement both clinically and radiologically; however, the use of a PGA-HA-based CFS in addition to this procedure can improve the clinical and radiological recovery.

Abstract
OBJECTIVES This study aims to evaluate the efficacy of high-molecular-weight hyaluronic acid (HMWHA) and lactoferrin (LF) injections on temporomandibular joint (TMJ) cartilage and subchondral bone in mono-iodoacetate (MIA)-induced temporomandibular joint osteoarthritis model in rats. MATERIALS AND METHODS In this in vivo study, a total of 24 rats were divided into three groups as follows: saline group (Group 1), HMWHA group (Group 2), and LF group (Group 3) including eight rats in each group. The intra-articular injections were administered once a week for three weeks after osteoarthritis was induced. All animals were euthanized 28 days after induction of osteoarthritis, and TMJs were harvested for histomorphometric, immunohistochemical, and micro-computed tomography (CT) analysis. RESULTS There was no significant difference between the HMWHA and LF groups in terms of the histomorphometric and immunohistochemical analysis results (p>0.05). According to the micro-CT analysis, the LF group had the highest mean bone volume fraction (74.9±0.5) and trabecular thickness (0.122±0.002), while the saline group had the lowest mean values (55.0±0.3 and 0.071±0.002, respectively) (p<0.001). There was no significant difference between the HMWHA and LF groups according to the micro-CT analysis (p>0.05). Both groups had better healing effects than the saline group in all analyses. CONCLUSION Lactoferrin has a healing effect at least as much as HMWHA in MIA-induced TMJ osteoarthritis. We suggest that LF may be evaluated in future clinical studies as a promising agent in the treatment of osteoarthritis.

Abstract
OBJECTIVES The aim of this study was to compare the effects of hyaluronic acid (HA), N-acetyl cysteine (NAC), and deproteinized calf serum on cartilage healing after the creation of traumatic cartilage injury in a rat model. MATERIALS AND METHODS A total of 48 rats, each weighing an average of 350 g, were randomly separated into four groups of 12. An osteochondral defect was created, 2-mm-wide and 3-mm deep in each rat. Injections were made to the knees of the rats as saline solution in Group 1, deproteinized calf serum in Group 2, NAC in Group 3, and HA in Group 4. At the end of 12 weeks, all rats were sacrificed and tissues were evaluated histologically. RESULTS The HA group had a better cell morphology, tissue morphology, surface architecture, and vascularity than the other groups (p<0.001). Matrix staining, chondrocyte clustering, and the assessment scores of the mid, deep, superficial zones, and overall were higher in the HA group than in the other groups (p<0.001). The NAC showed a better tissue morphology, cell morphology, and vascularity than the control group (p=0.003, p<0.001, and p<0.001, respectively). CONCLUSION Hyaluronic acid was the most effective agent in cartilage healing compared to NAC and deproteinized calf serum. In addition, the NAC was more effective compared to the control group.

[PMID: 36362308 PMCID: PMC9658499 DOI: 10.3390/ijms232113517] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 10/28/2022] [Accepted: 10/30/2022] [Indexed: 07/30/2023] Open
Abstract
Adipose tissue contains adult mesenchymal stem cells that may modulate the metabolism when applied to other tissues. Stromal vascular fraction (SVF) can be isolated from adipose tissue mechanically and/or enzymatically. SVF was recently used to decrease the pain and improve the function of knee osteoarthritis (OA) patients. Primary and/or secondary OA causes inflammation and degeneration in joints, and regenerative approaches that may modify the natural course of the disease are limited. SVF may modulate inflammation and initiate regeneration in joint tissues by initiating a paracrine effect. Chemokines released from SVF may slow down degeneration and stimulate regeneration in joints. In this review, we overviewed articular joint cartilage structures and functions, OA, and macro-, micro-, and nano-fat isolation techniques. Mechanic and enzymatic SVF processing techniques were summarized. Clinical outcomes of adipose tissue derived tissue SVF (AD-tSVF) were evaluated. Medical devices that can mechanically isolate AD-tSVF were listed, and publications referring to such devices were summarized. Recent review manuscripts were also systematically evaluated and included. Transferring adipose tissues and cells has its roots in plastic, reconstructive, and aesthetic surgery. Micro- and nano-fat is also transferred to other organs and tissues to stimulate regeneration as it contains regenerative cells. Minimal manipulation of the adipose tissue is recently preferred to isolate the regenerative cells without disrupting them from their natural environment. The number of patients in the follow-up studies are recently increasing. The duration of follow up is also increasing with favorable outcomes from the short- to mid-term. There are however variations for mean age and the severity of knee OA patients between studies. Positive outcomes are related to the higher number of cells in the AD-tSVF. Repetition of injections and concomitant treatments such as combining the AD-tSVF with platelet rich plasma or hyaluronan are not solidified. Good results were obtained when combined with arthroscopic debridement and micro- or nano-fracture techniques for small-sized cartilage defects. The optimum pressure applied to the tissues and cells during filtration and purification of the AD-tSVF is not specified yet. Quantitative monitoring of articular joint cartilage regeneration by ultrasound, MR, and synovial fluid analysis as well as with second-look arthroscopy could improve our current knowledge on AD-tSVF treatment in knee OA. AD-tSVF isolation techniques and technologies have the potential to improve knee OA treatment. The duration of centrifugation, filtration, washing, and purification should however be standardized. Using gravity-only for isolation and filtration could be a reasonable approach to avoid possible complications of other methodologies.

Abstract
OBJECTIVES This study aims to investigate whether ultra-fresh osteochondral allograft (OCA) transplantation was a good therapeutic alternative for the treatment of otherwise challenging, massive osteochondral defects in the knee joint. PATIENTS AND METHODS Between April 2011 and July 2022, a total of 16 ultra-fresh knee transplantations (9 males, 7 females; median age: 30.2 years; range, 14 to 62 years) having large osteochondral defects on femoral condyles were included. The operations were performed by two surgeons. The condition of the patients were evaluated based on regular follow-up physical examinations, imaging studies and by recording and evaluating clinical scores (modified Cincinnati scores, and 2000 International Knee Documentation Committee [IKDC] scores). RESULTS The median follow-up was 65±48 (range, 6 months to 12 years). At two years after transplantation, there was a significant improvement in the modified Cincinnati scores (preoperative score of 35.75 increased to 83.75; p<0.001) and also to the IKDC scores (preoperative score of 28.7 increased to 76.3; p<0.001). One patient developed an early septic complication, and another three patients underwent reoperation after the OCA transplantations for non-septic reasons. CONCLUSION Ultra-fresh OCA transplantation is a good therapeutic alternative for the treatment of otherwise challenging, massive osteochondral defects in the knee joint. Such a shortening of the transplantation time and its positive effect on the better long-term survival of transplanted chondrocytes has not yet been proven; however, the minimizing of transplantation time may create the conditions necessary for successful OCA transplantations many years after the implantation.

Abstract
Subchondral bone marrow lesions (BMLs) are areas of disease within subchondral bone that appear as T1 hypointense and T2 hyperintense ill-defined areas of bone marrow on magnetic resonance imaging. The most common bone marrow lesions include subchondral lesions related to osteoarthritis, osteochondral defects, and avascular necrosis. Emerging therapies include autologous biologic therapeutics, in particular mesenchymal stem cells (MSCs), to maintain and improve cartilage health; MSCs have become a potential treatment option for BMLs given the unmet need for disease modification. Active areas in the preclinical research of bone marrow lesions include the paracrine function of MSCs in pathways of angiogenesis and inflammation, and the use of bioactive scaffolds to optimize the environment for implanted MSCs by facilitating chondrogenesis and higher bone volumes. A review of the clinical data demonstrates improvements in pain and functional outcomes when patients with knee osteoarthritis were treated with MSCs, suggesting that BM-MSCs can be a safe and effective treatment for patients with painful knee osteoarthritis with or without bone marrow lesions. Preliminary data examining MSCs in osteochondral defects suggest they can be beneficial as a subchondral injection alone, or as a surgical augmentation. In patients with hip avascular necrosis, those with earlier stage disease have improved outcomes when core decompression is augmented with MSCs, whereas patients in later stages post-collapse have equivalent outcomes with or without MSC treatment. While the evidence for the use of MSCs in conditions with associated bone marrow lesions seems promising, there remains a need for continued investigation into this treatment as a viable treatment option. Common BMLs include osteoarthritis, osteochondral defects, and avascular necrosis. Patients with knee osteoarthritis treated with MSCs show improved pain and function. MSCs used as subchondral injection or surgical augmentation in osteochondral defects Improved outcomes of early hip avascular necrosis after core decompression with MSCs Additional preclinical and clinical evidence of MSCs as treatment for BMLs is needed.
