Freedom in Osteoarthritis of the Knee

The first peak of the external knee abduction moment (KAM) is often used as a surrogate measure of the medial compartment loading and has been correlated with pain and progression of knee osteoarthritis (OA). As a result, reducing the KAM is often the target of conservative interventions. OA should be considered as a “Whole Person” disease, including ecological psychosocial aspects. Scientists have developed gait alteration strategies to reduce the KAM. They attempted to force into a new position any particular part without reference to the pattern of the whole. We propose an alternative approach: in the vicinity of a special configuration of the knee, some or all of the components of the knee become overloaded. This study has shown that when six lines $1′,$2′,$3′,$4′,$5′,$6′ are so situated that forces acting along them equilibrate when applied to one degree of freedom, 1° F knee, a certain determinant vanishes. We wish to define the six lines as the knee complex in involution by virtue of some constraint upon the knee.

Study of oral glucosamine, methylsulfonylmethane and their combination in osteoarthritis of the knee

Background: Osteoarthritis (OA) of the knee is the most common degenerative joint disorder that results in disability and increased morbidity. Conventional treatment of OA with non-steroidal anti-inflammatory drugs (NSAIDs) often leads to serious adverse side effects that may increase morbidity and mortality. Glucosamine and Methylsulfonylmethane (MSM) have anti-inflammatory and analgesic properties which may supplement NSAIDs. Hence this study was aimed to determine the effectiveness and safety of these drugs in the management of knee OAMethods: 76 (63.33%) female and 44 (36.67%) male patients of OA of the knees were divided equally into four groups depending upon the therapy with Glucosamine or MSM or their combination (study groups) or none of them (control group) for 12 weeks. After the written consent, a detail Clinical History& Examination, Biochemical investigations, X-rays of chest and knees and ECG were done. The outcome of the treatment was assessed by Western Ontario and McMaster University Osteoarthritis (WOMAC) Index and for any adverse drug effects.Results: After 12 weeks of study there was significant decrease in mean WOMAC pain scores (27.29-39.13) and total aggregate scores (23.53-37.14%) in study groups (p<0.01-p<0.001) as compared to control group (14.28 % and 8.82% respectively). Besides the relief of pain and improvement in physical functions were superior in patients treated with combination therapy. Conclusions: This study showed Glucosamine & MSM are effective in the management of OA of knee and are safe health supplement to NSAIDs while their combination was more superior and effective.

Intra- and extra-capsular ganglia at the gastrocnemius origin and association with meniscal tears and severity of osteoarthritis of the knee joint

Background The association between size of ganglia or type of ganglia (intra-articular or extra-articular) and meniscal tears or severity of the osteoarthritis (OA) is not evaluated. Purpose To evaluate the prevalence, size, and location of intra- and extra-capsular ganglia at the gastrocnemius origin and to assess their associations with meniscal injury and grades of OA. Material and Methods This study included 301 consecutive patients who had knee pain and had undergone magnetic resonance imaging (MRI) of the knee. We evaluated presence of ganglia at the gastrocnemius muscle origin site and diagnosed whether it was an intra-capsular located or mixed-capsular located (intra-capsular and extra-capsular) and then measured the diameter of each ganglion. After two weeks, we evaluated whether articular cartilage injury existed. The presence of a meniscal tear was also recorded. Results A total of 186 patients (93%) had intra- and extra-capsular ganglia. Intra-capsular ganglia were found in 183 cases (91%) and mixed-capsular ganglia were found in 16 cases (8%). In cases with intra- and extra-capsular ganglia, more meniscal tears were found ( P = 0.029). Intra-capsular ganglia showed more meniscal tears ( P = 0.021). Intra-capsular ganglia were more likely to have high-grade OA ( P = 0.043). Patients who had a meniscal tear displayed larger-sized ganglia, especially of the intra-capsular type ( P = 0.044). Conclusion Patients with intra- and extra-capsular ganglia, especially of the intra-capsular type, are more likely to have meniscal injury and more severe OA. Patients with a meniscal tear or OA are more likely to have larger intra- and extra-capsular ganglia, especially of the intra-capsular type.

Is Culture Expansion Necessary in Autologous Mesenchymal Stromal Cell Therapy to Obtain Superior Results in the Management of Knee Osteoarthritis?—Meta-Analysis of Randomized Controlled Trials

Study Design: Meta-analysis. Objectives: We aimed to analyze the impact of cultured expansion of autologous mesenchymal stromal cells (MSCs) in the management of osteoarthritis of the knee from randomized controlled trials (RCTs) available in the literature. Materials and Methods: We conducted independent and duplicate electronic database searches including PubMed, Embase, Web of Science, and Cochrane Library until August 2021 for RCTs analyzing the efficacy and safety of culture-expanded compared to non-cultured autologous MSCs in the management of knee osteoarthritis. The Visual Analog Score (VAS) for pain, Western Ontario McMaster University’s Osteoarthritis Index (WOMAC), Lysholm score, Knee Osteoarthritis Outcome Score (KOOS), and adverse events were the analyzed outcomes. Analysis was performed in R-platform using OpenMeta [Analyst] software. Results: Overall, 17 studies involving 767 patients were included for analysis. None of the studies made a direct comparison of the culture expanded and non-cultured MSCs, hence we pooled the results of all the included studies of non-cultured and cultured types of MSC sources and made a comparative analysis of the outcomes. At six months, culture expanded MSCs showed significantly better improvement (p < 0.001) in VAS outcome. Uncultured MSCs, on the other hand, demonstrated significant VAS improvement in the long term (12 months) in VAS (p < 0.001), WOMAC (p = 0.025), KOOS score (p = 0.016) where cultured-expanded MSCs failed to demonstrate a significant change. Culturing of MSCs did not significantly increase the complications noted (p = 0.485). On sub-group analysis, adipose-derived uncultured MSCs outperformed culture-expanded MSCs at both short term (six months) and long term (12 months) in functional outcome parameters such as WOMAC (p < 0.001, p = 0.025), Lysholm (p < 0.006), and KOOS (p < 0.003) scores, respectively, compared to their controls. Conclusions: We identified a void in literature evaluating the impact of culture expansion of MSCs for use in knee osteoarthritis. Our indirect analysis of literature showed that culture expansion of autologous MSCs is not a necessary factor to obtain superior results in the management of knee osteoarthritis. Moreover, while using uncultured autologous MSCs, we recommend MSCs of adipose origin to obtain superior functional outcomes. However, we urge future trials of sufficient quality to validate our findings to arrive at a consensus on the need for culture expansion of MSCs for use in cellular therapy of knee osteoarthritis.

Results of use of polyacrylamide gel Noltrexsin in patients with different grades of gonarthrosis in outpatient practice

Introduction. Osteoarthritis of the knee joints is the most common joint disease affecting more than 80% of people over 55 years of age. The priority method for the treatment of gonarthrosis is the use of local injection therapy with the introduction of synovial fluid endoprostheses based on hyaluronic acid, included in the Second Step of the ESCEO 2019 algorithm. Viscoelastic polyacrylamide gels for intra-articular administration since 2003 have also shown their high effciency in the symptomatic OA treatment. Since 2018, the new 3rd generation PAAG endoprosthesis of synovial fluid, Noltrexsin, has been actively used.Objective. To compare the efficacy and safety of Noltrexsin viscoprosthesis use with oral NSAIDs in patients with grade I-III of gonarthrosis.Materials and methods. 40 patients with gonarthrosis participated in a comparative study of the effcacy and safety of injection therapy Noltrexsin 4.0 ml No. 2 (study group, А) and oral administration of NSAIDs 200 mg per day (comparison group, В). NSAIDs were taken in groups A and B, the duration of therapy in both groups was 1 month. The results were evaluated by standard examination methods, including measuring the range of motion in the joint and scoring of physical signs, tests with walking up the stairs and at a distance, VAS, WOMAC, Lequesne Index.Results. In group А, a more signifcant reduction in pain according to VAS was revealed to 15–20 mm at the grade I–II of gonarthrosis and up to 25–30 mm in the grade III, a decrease in the Lequesne index to 1–2 and 3–4 points, respectively. In group В with a standard therapy, and then on-demand within 6 months, a decrease in VAS was revealed on the 8–9th day, and after 6 months the level of pain at the grade I–II did not exceed 20–25 mm, at the grade 3 it did not decrease below 40–45 mm. The Lequesne Index decreased to 2 points at the grade I–II and to 6–7 points at the grade III. Changes of WOMAC index correlated with VAS.Conclusions. 1. Noltrexsin can be used as a safe endoprosthesis of synovial fluid in the form of local injection therapy in patients with insufficient effect of chondroprotectors and NSAIDs. 2. Noltrexsin is recommended for use at all stages of arthrosis, as well as in comorbid patients.

Method Categorization of Stem Cell Therapy for Degenerative Osteoarthritis of the Knee: A Review

Current clinical applications of mesenchymal stem cell therapy for osteoarthritis lack consistency because there are no established criteria for clinical processes. We aimed to systematically organize stem cell treatment methods by reviewing the literature. The treatment methods used in 27 clinical trials were examined and reviewed. The clinical processes were separated into seven categories: cell donor, cell source, cell preparation, delivery methods, lesion preparation, concomitant procedures, and evaluation. Stem cell donors were sub-classified as autologous and allogeneic, and stem cell sources included bone marrow, adipose tissue, peripheral blood, synovium, placenta, and umbilical cord. Mesenchymal stem cells can be prepared by the expansion or isolation process and attached directly to cartilage defects using matrices or injected into joints under arthroscopic observation. The lesion preparation category can be divided into three subcategories: chondroplasty, microfracture, and subchondral drilling. The concomitant procedure category describes adjuvant surgery, such as high tibial osteotomy. Classification codes were assigned for each subcategory to provide a useful and convenient method for organizing documents associated with stem cell treatment. This classification system will help researchers choose more unified treatment methods, which will facilitate the efficient comparison and verification of future clinical outcomes of stem cell therapy for osteoarthritis.
