Potential of diacerein in combination with aerobic exercise in comprehensive treatment of knee osteoarthritis

BACKGROUND: Knee osteoarthritis is a common degenerative disease characterized by cartilage destruction and inflammatory changes in the synovial membrane. Obesity and metabolic syndrome are significant risk factors that exacerbate inflammatory processes and contribute to the progression of osteoarthritis. Modern treatment methods include both pharmacological agents and non-pharmacological approaches such as aerobic exercise. AIM: To evaluate and compare the effectiveness of diacerein combined with aerobic physical activity (Nordic walking) in the comprehensive treatment of knee osteoarthritis. MATERIALS AND METHODS: The study involved 65 patients aged 45 to 70 years with knee osteoarthritis and metabolic syndrome. The participants were divided into three groups. The first group received diacerein (Artrocare); the second group was engaged in Nordic walking; the third group – a combination of these methods. The visual analog scale of pain, Western Ontario and McMaster University Osteoarthritis (WOMAC) index, quality of life (Short Form-36), glycated hemoglobin levels, and other biochemical parameters were assessed over 16 weeks of observation. RESULTS: The study demonstrated statistically significant reductions in pain levels and improvements in functional parameters in all the groups. The greatest improvements were observed in the group receiving combined therapy. The method showed a significantly positive impact on quality of life and reduced the need for analgesics in comorbid patients. Additionally, the patients with metabolic syndrome showed improved biochemical parameters with the combination of diacerein and Nordic walking. CONCLUSIONS: The combined use of diacerein and Nordic walking is an effective and safe method for treating knee osteoarthritis, particularly in patients with metabolic syndrome. This approach significantly reduces pain, improves joint function, and enhances overall quality patient’s life.

Consideration of the EXiLE test for predicting anaphylaxis after diclofenac etalhyaluronate administration

Diclofenac etalhyaluronate, an active pharmaceutical ingredient in JOYCLU® (JCL), serves as a joint function improvement agent in knee and hip osteoarthritis patients. However, frequent cases of anaphylaxis induced by JCL administration have been reported. Recent clinical research suggests the potential utility of the basophil activation test (BAT) in predicting JCL-induced anaphylaxis. Nonetheless, the BAT is deemed impractical for routine diagnostic testing due to complex procedures involving whole blood stimulation and flow cytometry-based analyses. In the study reported here, an IgE crosslinking-induced luciferase expression (EXiLE) test which uses patient sera without complicated procedures, was performed with patients who had received JCL, with or without subsequent anaphylactic symptoms. The results of this test were then compared with those of the BAT reported in a clinical research study. Of the six BAT-positive JCL-induced anaphylaxis-experienced patients, four were positive in the EXiLE test and all non-experienced patients were negative in both the BAT and EXiLE tests, thus illustrating a high concordance rate of 92.3%. Further validation of testing conditions is expected to improve these rates. Notably, complement inactivation treatment led to a positive EXiLE result in a BAT-negative patient. In conclusion, it appears that the EXiLE test exhibits promise as an alternative to BAT for predicting JCL-induced anaphylaxis, and in so doing offers a simpler diagnostic approach.

Iron Chelators Augment Large Osteochondral Allograft Osseointegration in a Preclinical Canine Model.

Osteochondral allograft transplantation (OCAT) can be a successful joint restoration treatment option for large post-traumatic articular defects but is still associated with significant revision and failure rates. Despite recent advances that have improved OCAT success, insufficient osteochondral allograft (OCA) osseointegration remains a major cause of failure. Deferoxamine (DFO) is an effective angiogenic and osteo-anabolic iron chelator that consistently promotes bone neovascularization and regeneration. This study was designed to investigate local delivery of DFO for augmenting OCA osseointegration using a preclinical canine model for OCAT in the knee and hip as commonly affected joints. On Institutional Animal Care and Use Committee (IACUC) approval, 12 purpose-bred dogs underwent OCAT of the femoral head or femoral condyles with DFO or DFO-free (controls) microspheres in recipient sites. OCA revascularization, cellular repopulation, and integration were evaluated based on functional, diagnostic imaging, microcomputed tomography, histology, and immunohistochemistry outcome measures. Local delivery of DFO into OCAT recipient sites was associated with maintained or improved joint function, superior radiographic appearance, significantly greater trabecular thickness, higher bone volume, and new bone ingrowth compared with DFO-free controls. OCA osseointegration is dependent on cellular repopulation and neovascularization, resulting in new bone ingrowth through creeping substitution, and insufficient osseointegration with resorption and subsidence of the OCA remains a major cause of failure after transplantation. The results of this study suggest that local delivery of DFO using a controlled microsphere release system may reduce resorption and improve revascularization and cellular repopulation to increase new bone ingrowth, potentially expediting OCA osseointegration after transplantation.

Efficacy of hypertonic dextrose (prolotherapy) in early knee osteoarthritis: a short term outcome

Background: Knee osteoarthritis (OA) is a prevalent, painful, and progressive condition significantly affecting patients' quality of life and imposing a social and economic burden. Traditionally managed through symptom relief and joint function improvement, research is increasingly focusing on disease-modifying treatments. Dextrose prolotherapy, a low-cost alternative involving the injection of a hypertonic solution, has shown promise despite limited acceptance in current guidelines. Methods: This prospective cohort study, approved by the Institutional Ethical Board of Jamia Hamdard University, assessed the effects of 12.5% hypertonic dextrose prolotherapy in 92 patients with knee OA. Patients received injections at multiple sites over a 6-week period. Outcomes were evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and visual analog scale (VAS) scores at baseline, 4, 8, 16, and 24 weeks. Results: Significant improvements were observed in both WOMAC and VAS scores. WOMAC scores decreased from 53.83 to 26.70 (p<0.0001), and VAS scores dropped from 7.12 to 3.06 (p<0.0001) at the 24-week follow-up. No major complications were noted, with minimal adverse effects reported. Improvement was consistent across all OA grades. Conclusions: Dextrose prolotherapy demonstrated substantial, sustained improvements in pain and function in knee OA patients. Given its safety, low cost, and efficacy, it represents a viable therapeutic option, especially in resource-constrained settings. Further high-quality randomized controlled trials are needed to confirm these findings and optimize treatment protocols.

Treatment of patients with periprosthetic infection and management of Paprosky type 2C cavitary defects at the stage of articulating spacer installation

Introduction Due to the constant increase in the number of primary and revision hip arthroplasties, the incidence of complications has been also increasing. Periprosthetic joint infection (PJI) is the most common and dangerous complication in joint arthroplasty, including PJI with cavitary defects of the acetabulum (Paprosky type 2C).The purpose of the work was to demonstrate successful results of managing acetabular defects in patients with periprosthetic infection at the stage of installing an articulating spacer.Materials and methods The patients underwent surgical management of cavitary defects of the acetabulum with allobone plastic material at the stage of installation of an articulating spacer impregnated with antibacterial drugs. A clinical and functional assessment of the effectiveness of treatment of patients with PJI of the hip joint, who underwent bone grafting of acetabular defects at the first stage of two-stage revision arthroplasty, was carried out. Remission of the infectious process was assessed according to the ICM 2013 (International Consensus Meeting), and the function of the affected limb was assessed according to the HHS (Harris Hip Score).Results At a 6-month follow-up after implantation, there were no clinical and laboratory manifestations of PJI and radiological signs of instability of the implant components. Bone grafting was evaluated to be satisfactory; the function of the affected joint restored to 80–90 to HHS points. Remission of the infectious process according to ICM was achieved.Discussion Clinical cases studied demonstrate a positive result of treatin PJI with plastic surgery of cavitary defects of the acetabular bottom at the stage of articulating spacer installation. Filling acetabular defects at the sanitizing stage (implantation of a spacer) subsequently provides improvement of primary fixation and osseointegration of the acetabular component when converting the spacer to a permanent implant. This is due to an increase in the contact area of the acetabular component with bone tissue (native bone and remodeled allobone material).Conclusion The treatment of the first clinical case improved joint function from 24 to 85 HHS points, and in the second from 27 to 76 HHS points. The use of defect filling techniques enabled to stop the infection and improve functional results.

Efficacy of disease-modifying osteoarthritis drugs in the treatment of osteoarthritis

Background: Osteoarthritis is the most common form of chronic inflammatory arthritis, and its prevalence is steadily increasing owing to its association with aging. Therefore, understanding and implementing appropriate treatments for osteoarthritis in clinical practice is becoming increasingly important. Additionally, there is active research on a new approach for treating osteoarthritis: disease-modifying osteoarthritis drugs (DMOADs).Current Concepts: Several global osteoarthritis treatment guidelines exist; this article introduces the guidelines of the American College of Rheumatology and Osteoarthritis Research Society International, which are among the most widely recognized. A common theme across various guidelines is that exercise and weight loss are the primary recommended treatments. As for pharmacotherapy, the top recommendations include topical nonsteroidal anti-inflammatory drugs (NSAIDs) and oral NSAIDs. Although multiple classes of drugs such as DMOADs are being actively researched to slow the progression of osteoarthritis, no drug has yet been confirmed to be clinically effective or approved for use.Discussion and Conclusion: A deeper understanding of osteoarthritis treatment can help prevent malpractice and improve patient outcomes. While current treatments focus primarily on symptom management, the development of effective DMOADs holds promise for fundamentally altering the disease course and improving joint function and quality of life.

Efficacy of intra-articular injection of combined platelet-rich-plasma (PRP) and hyaluronic acid (HA) in knee degenerative joint disease: a prospective, randomized, double-blind clinical trial.

Intra-articular injections of hyaluronic acid (HA) and platelet-rich plasma (PRP) represent promising options in the conservative treatment of early stages of knee osteoarthritis (OA). Although the combined use of these two compounds seems to have a synergistic effect in pre-clinical studies, few clinical trials compared the association of PRP and HA with PRP and HA alone. The aim of study is toevaluate the efficacy of combined intra-articular injections of PRP and HA in the treatment of mild to moderate knee OA, compared to PRP and HA alone. One hundred and seventy-four patients were prospectively enrolled and randomized to undergo three intra-articular injections of either HA or PRP or the combination of PRP and HA with a two-week interval period. Patients were evaluated before treatment and after 3, 6, and 12months using Western Ontario and McMaster Universities Osteoarthritis (WOMAC) score, Knee Injury and Osteoarthritis Outcome Score, International Knee Documentation Committee subjective score, Visual Analogue Scale and TEGNER Activity Scores. All the treatments proved to be effective in reducing pain and improving joint function. The analysis of covariance did not show statistically significant differences among the three groups for any of the investigated outcome parameters after 6 and 12months (WOMAC: p = 0.45 and p = 0.64, respectively). No significant differences were found in terms of adverse events (p = 0.49) and painkiller use (p = 0.28 and p = 0.56, respectively) among the three groups. This multicenter, prospective, randomized, double-blind controlled trial revealed that intra-articular injections of PRP + HA, PRP, or HA represent a safe and viable treatment with comparable efficacy in terms of pain relief and functional outcomes in mild to moderate knee OA.

Unveiling the Role of Radiotherapy in Managing Pigmented Villonodular Synovitis (PVNS): A Unique Case Analysis

Background and Aims: Pigmented villonodular synovitis (PVNS) is an uncommon but aggressive proliferative process affecting the synovium. Diffuse pigmented villonodular synovitis (DPVNS) is a type that affects the whole joint and if left untreated, it can lead to joint destruction and osteoarthritis. Only surgical excision can lead to local recurrences in DPVNS. Postoperative radiotherapy can significantly lower the incidences of local recurrences and improve functional outcomes. Materials and Methods: Here we present a rare case report of a lady with biopsy-proven DPVNS where postoperative radiotherapy was given. Results: At a 48-month follow-up, the patient is free of disease with improved joint function. Discussion: Given the improved local control, low morbidity and remarkable improvement in joint functions, postoperative radiotherapy should be routinely considered in cases of DPVNS if complete excision is doubtful.

A comprehensive predictive model for postoperative joint function in robot-assisted total hip arthroplasty patients: combining radiomics and clinical indicators.

Total hip arthroplasty (THA) effectively treats various end-stage hip conditions, offering pain relief and improved joint function. However, surgical outcomes are influenced by multifaceted factors. This research aims to create a predictive model, incorporating radiomic and clinical information, to forecast post-surgery joint function in robot-assisted THA (RA-THA) patients. The study set comprised 136 patients who underwent unilateral RA-THA, which were subsequently partitioned into a training set (n = 95) and a test set (n = 41) for analysis. Preoperative CT imaging was employed to derive 851 radiomic characteristics, selecting those with an intra-class correlation coefficient > 0.75 for analysis. Least absolute shrinkage and selection operator regression reduced redundancy to six significant radiomic features. Clinical data including preoperative Visual Analog Scale (VAS), Harris Hip Score (HHS), and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score were collected. Logistic regression identified significant predictors, and three models were developed. Receiver operating characteristic and decision curves evaluated the models. Preoperative VAS, HHS, WOMAC score, and radiomics feature scores were significant predictors. In the training set, the AUCs were 0.835 (clinical model), 0.757 (radiomic model), and 0.891 (combined model). In the test set, the AUCs were 0.777 (clinical model), 0.824 (radiomic model), and 0.881 (combined model). The constructed nomogram prediction model combines radiological features with relevant clinical data to accurately predict functional outcomes 3years after RA-THA. This model has significant prediction accuracy and broad clinical application prospects and can provide a valuable reference for formulating personalized treatment plans and optimizing patient management strategies.

Efficacy and safety of SKCPT in patients with knee osteoarthritis: A multicenter, randomized, double-blinded, active-controlled phase III clinical trial

Ethnopharmacological relevanceOsteoarthritis (OA) is the most prevalent type of arthritis worldwide and a leading cause of years lost to pain and disability. Among the current pharmacological treatments for OA, symptomatic slow-acting drugs for OA (SYSADOA) induce pain relief and aim to improve joint function by relieving inflammation while causing fewer gastrointestinal and cardiovascular adverse events than non-steroidal anti-inflammatory drugs (NSAIDs). SKCPT is a herbal SYSADOA formulated from Clematis mandshurica, Trichosanthes kirilowii, and Prunella vulgaris powdered extracts. This preparation has been shown to induce cartilage protection and anti-inflammatory effects in preclinical studies and inhibit glycosaminoglycan degradation and catabolic gene expression in human OA chondrocytes and cartilage. Aim of the studyWe aimed to evaluate the non-inferiority of SKCPT to celecoxib and safety for treating knee OA. Materials and methodsThis multicenter, randomized, double-blind, phase III clinical trial enrolled adults with primary knee OA who were randomized (1:1) to SKCPT 300 mg twice daily or celecoxib 200 mg once daily for 12 weeks. ResultsIn total, 278 patients were assigned to treatment (SKCPT, 136; celecoxib, 142) for approximately 12 weeks. The primary endpoint was the mean change of Korean Western Ontario and McMaster Universities Osteoarthritis Index (K-WOMAC) pain subscale scores from baseline to Day 84. The mean change (least squares [LS] mean ± standard error) from baseline to Day 84 was −23.74 ± 1.48 for SKCPT and −25.88 ± 1.44 for celecoxib. The two-sided 95% confidence interval of the difference (LS mean) between groups was [−1.94, 6.20], confirming that the upper limit was less than the non-inferiority margin of 10. Additionally, there were no significant differences in the secondary endpoints (mean changes of K-WOMAC pain, physical, stiffness subscale, and total score, and the frequency and number of doses of rescue medications) between groups at all time points. Differences between groups in adverse events and adverse drug reactions were not significant, and no serious adverse events occurred. ConclusionsSKCPT efficacy was non-inferior, and its safety profile was similar, to celecoxib. Building on previous results showing that SYSADOA reduce NSAID intake, the present results suggest that the SYSADOA SKCPT could effectively replace NSAIDs in knee OA treatment while avoiding long-term side effects.

The applied study to improve the treatment of knee sports injuries in ultimate frisbee players based on personalized exercise prescription: a randomized controlled trial.

Ultimate frisbee can lead to severe sports injuries, especially joint injuries in the lower limbs, such as knee meniscus injuries. This study examines the impact of personalized exercise therapy on knee meniscus injuries in ultimate frisbee players in the Lingnan region of China. Seventy-six patients with confirmed meniscal injuries participated in the study, divided into an intervention group (n = 38) and a control group (n = 38). The control group received standard treatment, including drug therapy and physical therapy. The intervention group received standard treatment plus a personalized exercise regimen based on FITT-VP (frequency, intensity, time, type, volume, and progression) principles, incorporating strength training, aerobic exercise, flexibility training, neuromuscular training, and aquatic exercise. This program was monitored and adjusted over a six-month period through both online and offline methods. The primary outcomes were joint range of motion (ROM), thigh circumference atrophy index (TCAI), Lysholm Rating Scale (LRS) scores, and visual analog scores (VAS). The secondary outcome was the International Knee Documentation Committee (IKDC) score. Data were collected before the intervention, and at 1 month and 6 months after the intervention. Statistical analysis was conducted using SPSS 24.0 and GraphPad 10.0, with a significance level set at α = 0.05. After 1 month, the intervention group showed significantly better results in ROM (116.67 ± 9.063), LRS score (86.316 ± 3.750), and IKDC score (80.473 ± 5.421) compared to the control group (111.784 ± 4.778, 82.579 ± 3.818, and 77.684 ± 4.430, respectively) (p < 0.05). The TCAI (3.219 ± 1.889) and VAS score (1.921 ± 0.673) in the intervention group were significantly lower than those in the control group (5.228 ± 2.131 and 2.710 ± 1.112, respectively) (p < 0.01). After 6 months, the differences in LRS and VAS scores between the groups were not significant. However, the intervention group continued to show significant improvements in ROM (134.934 ± 3.011), TCAI (1.107 ± 1.158), and IKDC score (93.315 ± 1.847) compared to the control group (125.395 ± 18.554, 4.574 ± 1.109, and 87.789 ± 4.437, respectively) (p < 0.05). Personalized exercise prescriptions offer significant therapeutic and rehabilitative benefits for ultimate frisbee players with knee meniscus injuries. This approach helps to reduce symptoms, alleviate pain, and improve joint function, muscle strength, and athletic performance after sports-related injuries.

Effect of oblique insertion at ashi point with long needle on joint function in female patients with knee osteoarthritis of early and middle stages

To compare the improvement of joint function in female patients with early-middle-stage knee osteoarthritis (KOA) treated by oblique insertion at ashi point with long needle and oral celecoxib capsule. A total of 105 female patients with early-middle-stage KOA were randomly divided into an observation group (65 cases, 6 cases dropped out, 3 cases were discontinued) and a control group (40 cases, 6 cases dropped out, 2 cases were discontinued). Patients in the observation group were treated with oblique insertion at ashi point (hard knots of quadriceps femoris, hamstring muscle, popliteal muscle, etc.) with long needle, once every other 3 days, twice a week, for a total of 2 weeks. Patients in the control group were treated with oral celecoxib capsules, 0.2 g each time, once a day for 2 weeks. Both groups started functional exercise after 2 weeks of treatment. The joint function score of Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and pain visual analogue scale (VAS) score of the two groups were observed before and after treatment and after 6 weeks of treatment completion (follow-up), the 12-item short-form health survey (SF-12) score was compared between the two groups before treatment and in follow-up, and the safety of the two groups was evaluated. After treatment and during the follow-up, the joint function scores of WOMAC and VAS scores of the two groups were lower than those before treatment (P<0.05). During the follow-up, the joint function scores of WOMAC and VAS scores were lower than those after treatment (P<0.05), and the SF-12 scores were higher than those before treatment (P<0.05) in the two groups. After treatment, the joint function score of WOMAC of the observation group was lower and the VAS score was higher than those of the control group (P<0.001, P<0.01). During the follow-up, the SF-12 score of the observation group was higher than that of the control group (P<0.05). No serious adverse reactions occurred in both groups. The treatment of oblique insertion at ashi point with long needle can improve the knee joint function and quality of life of female patients with early-middle-staqe KOA, which is better than oral celecoxib capsule.

From Stiffness to Strength: The Role of Physical Activity in Managing Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint inflammation, pain, and potential disability. While pharmacological treatments are central to managing RA, physical activity plays a crucial role in improving patient outcomes. This article explores the influence of physical activity on RA, detailing its benefits, challenges, and best practices. Physical activity offers numerous benefits for RA patients, including reduced pain, improved joint function, enhanced physical mobility, and better mental health. Regular exercise also mitigates the risk of cardiovascular disease, improves bone density, and contributes to overall quality of life. Suitable forms of physical activity for RA patients include low-impact aerobic exercises, strength training, flexibility exercises, balance training, and mind-body practices like yoga and Tai Chi. Despite these benefits, RA patients face challenges in engaging in physical activity, such as pain, fatigue, and psychological barriers. Properly tailored exercise programs, guided by healthcare professionals, can help overcome these challenges, ensuring that patients can safely incorporate physical activity into their management plans. This article highlights the importance of a multidisciplinary approach, integrating physical activity with conventional RA treatments, to optimize patient outcomes and enhance their quality of life.

The effect of radiation synovectomy with phosphorus-32 on the pain and swelling in 31 RA patients with resistant monoarthritis of the knee.

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by symmetric polyarthritis. RA is routinely treated by various systemic drugs; on the other hand, administration of intra-articular corticosteroids or different types of synovectomies can be used in case of systemic medication's failure. Chemical, radio isotopic, and surgical synovectomies are being used as therapeutic options for chronic synovitis to improve joint function. Chemical synovectomy is not well tolerated, and the long-term response is relatively low. Surgical synovectomy has a better success rate, but it recommends higher expenses. In radiation synovectomy, radioactive labeled particles are applied directly in the articular cavity, followed by homogeneous distribution in joint. Next, the radioactive particles are transported in the depth of synovia and phagocytized by inflammatory cells. Finally, the radiation leads to fibrosis and sclerosis of formerly inflamed synovial membrane; thus, it stops the inflammation and reduces the symptoms. It has a success rate of 40-100% and its effect can be similar to surgical synovectomy. Thirty-one patients with resistant monoarthritis of the knee were enrolled in this study. One millicurie of phosphorus-32 was injected into patients' knee via US guide. Saline was injected afterwards to prevent leakage. Direct pressure was performed after removing the needle and the knee was flexed slowly to ensure homogenous distribution and fixed with a splint for 1 to 2weeks. Patients were followed up after 2weeks, 1month, 2months, and 6months. The following variables were assessed by the treating rheumatologist: patients' pain, joint tenderness, effusion, and ROM. At the time of injection and after the first week, patients were investigated for any complication including infection, necrosis, pain, and swelling. The effect of clinical characteristics and demographic data on existing complications and the changes of pain, joint tenderness, effusion, and ROM was assessed. Thirty-one patients with the mean age of 54.5 ± 12.2years and the mean disease duration of 12 ± 6.5years were enrolled in this study. Mean DAS-28 ESR score for our patients was 4 ± 0.7. The pain, effusion, and reduced ROM were decreased significantly after all follow-up intervals. Knee tenderness was not affected in the first 2weeks, but it was reduced significantly after 1, 2, and 6months. No serious complications like infection and necrosis were reported through our study. 51.6% and 54.8% of our patients reported pain and swelling in the administration site. Furthermore, 19.4% and 16.1% of patients reported deterioration of pain and effusion in the first week of injection. In our study, we demonstrated that pain, tenderness, effusion, and ROM are improved after radiation synovectomy with phosphorus-32. We also showed that there was no serious adverse effect like infection and necrosis. However, more than half of our patients experienced pain and swelling of injection site at the time of administration. Key points • We demonstrated the efficacy of radiation synovectomy as a medication for monoarthritis. • The results of our study can lead to a bigger clinical trial to assess the benefits and adverse effects of radiation synovectomy in comparison to treatment with local or systemic corticosteroids.

The combined application of pulsed electromagnetic fields and platelet-rich plasma in the treatment of early-stage knee osteoarthritis: A randomized clinical trial.

This study aims to evaluate the therapeutic efficacy of combined treatment with pulsed electromagnetic fields (PEMFs) and platelet-rich plasma (PRP) injection in improving pain and functional mobility among patients with early-stage knee osteoarthritis (KOA). We hypothesize that this combined therapy can yield superior treatment outcomes. Based on the different treatment regimens, we divided 48 patients diagnosed with Kellgren-Lawrence grades I-III KOA into 3 groups: the PRP group, the PEMFs group, and the PRP + PEMFs group. Each subtype of KOA patients was randomly assigned to different treatment groups. In the PRP group, patients received intra-articular injections of leukocyte-rich platelet-rich plasma once a month for 3 consecutive months. In the PEMFs group, patients receive low-frequency PEMFs irradiation therapy with a frequency of 30 Hz and intensity of 1.5 mT, once daily, 5 times a week, for a consecutive treatment period of 12 weeks. In the PRP + PEMFs group, patients receive both of the aforementioned treatment protocol. The treatment effects on patients are evaluated at baseline and at weeks 4, 8, and 12 post-treatment. Assessment parameters include visual analog scale for pain, Western Ontario and McMaster Universities Osteoarthritis Index, Lequesne Index score, and knee joint range of motion. From the 4th to the 12th week of treatment, the visual analog scale scores, Western Ontario and McMaster Universities Osteoarthritis Index scores, and Lequesne index scores of patients in all 3 groups gradually decreased, while knee joint mobility gradually increased (P < .05). At weeks 4, 8, and 12 after treatment, the PRP combined with PEMFs group showed significantly better scores compared to the PRP group and the PEMFs group, with statistically significant differences (P < .05). A total of 7 patients experienced adverse reactions such as knee joint swelling, low-grade fever, and worsening knee joint pain after treatment, all of which disappeared within 1 week after treatment. The incidence of complications did not differ significantly among the 3 groups (P = .67). PRP, PEMFs, and the combination of PRP and PEMFs therapy all effectively alleviate knee joint pain and improve joint function. However, compared to single treatment modalities, the combined therapy of PRP and PEMFs demonstrates more pronounced efficacy.

Prospective comparative study of medial parapatellar and medial subvastus approaches in total knee arthroplasty

Introduction Total knee arthroplasty (TKA) is the treatment of end-stage osteoarthritis in patients who failed to respond to conservative treatment in providing significant pain relief and improving joint function. The medial parapatellar approach (MPP) allows adequate patellar eversion and sufficient knee flexion to expose the knee joint, but the incision through the quadriceps tendon may impair the extensor mechanism of the knee post-operatively. The subvastus approach (SV) completely spares both the quadriceps tendon and muscle and provides adequate exposure of the knee joint for the replacement procedure, SV maintains integrity of the patellar blood supply and reduces post-operative pain resulting in shorter hospital stay.The aim of this prospective study was to compare the results of the medial parapatellar and subvastus approaches in primary total knee arthroplasty (TKA) regarding postoperative pain, recovery of muscle strength, range of knee motion and return to regular daily activities.Materials and Methods Sixty patients underwent TKA at El-Hadara university hospital in Alexandria. The medial parapatellar apphroach (MPP) was performed in 30 patients while the subvastus approach (SV) was used for the other 30 patients. The choice of approach was randomly assigned.Results The statistical analysis of the results at the end of a 6-month follow-up showed that there were no significant differences between the patients in group 1 (MPP) and group 2 (SV) with respect to age, gender, comorbidity, side operated or body mass index (BMI). Regarding the functional knee scores (IKDC, WOMAC), there were no differences at 4 weeks, 3 months and 6 months postoperatively between the two groups. However, we found better outcomes in the SV group regarding the VAS score during the first five postoperative days, earlier quadriceps recovery by assessment of Straight Leg Raising test (SLR), while the operative time was longer in the SV group with less blood collected postoperatively in hemovac drain in the same group.Discussion In our study during the operation via the MPP approach, the index suture positioned at the superomedial border of the patella and the opposite suture on the medial retinacular flap had enabled the surgeon to avoid patellar maltracking during closure of the wound. In the SV group, the L-shaped incision of the medial capsule was considered an efficient landmark for accurate soft tissue closure avoiding the patellar maltracking.Conclusion The subvastus approach offers the advantage of keeping the integrity of quadriceps muscle and the extensor mechanism remains intact post-surgery. It causes less pain and less blood loss postoperatively than the regular parapatellar approach. The patient could recover the knee function in a shorter time with fewer complications, which is greatly in line with the concept of ERAS (Enhanced Recovery After Surgery).

The Role of External Application of Ancestral Poultices in the Treatment of Spondyloarthropathies in the Elderly

With the aging of the population, geriatric spinal and joint diseases have become an important factor affecting the quality of life of the elderly. Traditional Chinese medicine (TCM) treatments, due to their unique theoretical basis and practical experience, have shown some potential in relieving pain and improving joint function. Based on this, the role of external application of ancestral plasters on the treatment of spinal joint diseases in the elderly is discussed below for reference.

Critical evaluation of the current role of SYSADOA in the management of osteoarthritis (literature review)

Background. Osteoarthritis is a common chronic disease characterized by progressive degradation of all joint components and inflammation. The priority issue in the management of OA is sear­ching for drugs that simultaneously relieve symptoms, modify the course of the disease, and are safe for use. Symptoma­tic slow-ac­ting drugs (SYSADOA) are of considerable interest due to their potential to slow cartilage degeneration and potential osteoarthritis di­sease mo­difying effect. The purpose of the study was to ana­lyze current literature data on several types of SYSADOA, their biological role, mecha­nisms of effect on joints, effectiveness and safetye. ­Materials and methods. An analytical review of literature data was conducted using the ana­lysis of scientific databases PubMed, Web of Science, Scopus, Google Scholar for the period 2005–2024, the search was conducted using the keywords “osteoarthritis”, “SYSADOA”, “DMOAD”, “effectiveness”, “safety”. Results. Glucosamine salts (GA) and chondroitin sulfate (CS) are the most stu­died slow-acting drugs and have positive biological effects on joint tissues. Prescription salts of GA and CS have effect of pain relieve and joint function improvement as separate agents and also potentiate the effect in combination. Studies revealed limiting of cartilage volume loss and joint space narrowing – a potential DMOAD effect of these drugs. GA salts and CS drugs are safe, as they have no difference in the frequency of side effects compared to placebo. The quality of drugs largely depends on the type of raw materials and technological production process, which are not standardized now. Conclusions. The role of SYSADOA in the treatment of OA has not been definitively determined, and studies on the effectiveness of drugs such as SYSADOA and the study of their DMOAD effect are still ongoing. Further stu­dies should focus on the use of pharmacological class SYSADOA that have been properly purified and quality strictly supervised.

The Effectiveness of a Single Hyaluronic Acid Injection in Improving Symptoms and Muscular Strength in Patients with Knee Osteoarthritis: A Multicenter, Retrospective Study.

Knee osteoarthritis (KOA) is a progressive and multifactorial disease that leads to joint pain, muscle weakness, physical disability, and decreased quality of life. In KOA, the quantity of hyaluronic acid (HA) and the molecular weight (MW) are decreased, leading to joint pain due to increased wear of the knee articular cartilage. Arthrogenic muscle inhibition, which is usually found in patients with KOA, is associated with joint inflammation, pain, and swelling, also causing muscle atrophy, primarily of the anterior thigh muscles, and hindering the rehabilitation process. The aim of our work was to determine if a single HA infiltration could minimize the effects of arthrogenic muscle inhibition in patients with KOA in the short term, using isokinetic dynamometry to evaluate the strength of the knee extensor and flexor muscles of the thigh. Thirty patients with KOA who underwent both clinical and isokinetic assessment, and that received a single injection of HA, were retrospectively included. Our results showed that a single intra-articular injection of HA significantly reduces pain and improves joint function at four weeks, while non-statistically significant improvements were observed for the reference isokinetic parameter (maximum torque) at both 90°/s and 180°/s. Further high-quality studies are necessary to confirm the results of our study.

Therapeutic effect of San Bi Tang combined with glucosamine sulfate capsules in cold-dampness-type knee osteoarthritis.

Cold-dampness-type knee osteoarthritis is a common middle-aged and elderly disease, but its pathogenesis is not fully understood, and its clinical treatment has limitations. Glucosamine sulfate capsules are commonly used for treating arthritis, and San Bi Tang is a classic formula of traditional Chinese medicine (TCM) that has the effects of warming yang, dispelling dampness, relaxing muscles, and activating collaterals. This research hypothesized that the combination of modified San Bi Tang and glucosamine sulfate capsules could enhance the clinical efficacy of treating cold-dampness-type knee osteoarthritis through complementary effects. To analyze the clinical efficacy of San Bi Tang combined with glucosamine sulfate capsules when treating cold-dampness-type knee osteoarthritis. A total of 110 patients with cold-dampness-type knee osteoarthritis were selected as research subjects and randomly divided into a control group and an experimental group of 55 cases each. The control group received only treatment with glucosamine sulfate capsules, while the experimental group received additional treatment with modified San Bi Tang for a duration of 5 wk. The patients' knee joint functions, liver and kidney function indicators, adverse reactions, and vital signs were evaluated and analyzed using SPSS 26.0 software. Before treatment, the two groups' genders, ages, and scores were not significantly different, indicating comparability. Both groups' scores improved after treatment, which could indicate pain and knee joint function improvement, but the test group had better scores. The TCM-specific symptoms and the clinical efficacy of the treatment in the test group were higher. Before and after treatment, there were no abnormalities in the patients' liver and kidney function indicators. The combination of modified San Bi Tang and glucosamine sulfate capsules is superior to treatment with sulfated glucosamine alone and has high safety.
