OBJECTIVES
This study aimed to evaluate the effects of the combined hydrolyzed type 2 collagen, methylsulfonylmethane (MSM), glucosamine sulfate (GS), and chondroitin sulfate (CS) supplement on knee pain intensity in patients with knee osteoarthritis (OA).
PATIENTS AND METHODS
This multicenter, observational, noninterventional study included 98 patients (78 females, 20 males; mean age: 52.8±6.5 years; range, 40 to 64 years) who had Grade 1-3 knee OA between May 2022 and November 2022. The patients were prescribed the combination of hydrolyzed type 2 collagen, MSM, GS, and CS as a supplement for knee OA. The sachet form of the combined supplement containing 1250 mg hydrolyzed type 2 collagen, 750 mg MSM, 750 mg GS, and 400 mg CS was used once daily for two consecutive months. Patients were evaluated according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analog Scale (VAS)-pain, and Health Assessment Questionnaire (HAQ). Patients were scheduled to visit for follow-up four weeks (Visit 2) and eight weeks (Visit 3) after Visit 1 (baseline; day 0 of the study).
RESULTS
For the VAS-pain, WOMAC, WOMAC-subscale, and HAQ scores, the differences in improvement between the three visits were significant (p<0.001 for all). The patient compliance with the supplement was a median of 96.77%, both for Visit 2 and Visit 3.
CONCLUSION
The combination of hydrolyzed type 2 collagen, MSM, GS, and CS for eight weeks in knee OA was considered an effective and safe nutritional supplement.

OBJECTIVES
This study aims to compare the efficacy of intra-articular platelet-rich plasma (PRP) injections over a saline placebo in terms of reduction of pain and impact on quality of life among patients with hip osteoarthritis.
PATIENTS AND METHODS
A total of 60 patients (29 males, 31 females, mean age: 57.9±7.3 years; range, 47 to 69 years) with known hip osteoarthritis of Kellgren-Lawrance (KL) Grades 2/3 were randomized into placebo (n=30) and PRP groups (n=30) between June 2014 and June 2015. Both groups received intra-articular injections into the hip joint under ultrasound guidance for three consecutive weeks. The patients were followed for six months, and pain reduction was assessed using the Visual Analog Scale (VAS), Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire, and Short Form Health Survey-36 (SF-36).
RESULTS
Intra-articular PRP treatment showed no advantage over a saline placebo in terms of VAS scores during activity. Both groups showed a significant improvement in VAS activity scores at one and six months. The placebo group showed improvements in VAS resting scores, whereas the PRP group did not. Both groups showed no improvement in WOMAC-total scores. Both groups showed no significant improvement across most SF-36 domains with the exception of improved physical role functioning at one month and general health at one and six months in the placebo group.
CONCLUSION
Intra-articular injections of PRP show no significant difference compared to a saline placebo over a period of six months on pain, function, and quality of life scores in patients with hip osteoarthritis.

INTRODUCTION AND AIM
Osteoarthritis (OA) is a noninflammatory joint disease. If OA of the knee causes pain, decreased muscle strength and joint stiffness, exercise therapy is one of the most effective treatments for the disease. The aim of the present study was to evaluate the effect of aquatherapy on pain intensity and performance in women with OA with the assumption that it causes weightlessness.
METHODS
This is a quasiexperimental study. The sample size included 60 people who were randomly divided into experimental and control groups. The visual analogue scale was used to assess pain and timed up and go test (TUG), 30 Second Sit to Stand Test (30-S-CS), and 40-meter fast-paced walk test (40 MW) were used to assess performance. Data analysis was carried out using SPSS ver. 22.
RESULTS
The results of the present study showed a decrease in pain intensity from moderate to mild intensity. Also, physical performance dimensions in patients with OA were improved, so that the average TUG increased from 14.06 to 8.8 s. The average S-CS frequency increased from 4.86 to 8.4 s and 90 MW decreased from the average 93.43 to 72.66 s.
DISCUSSION AND CONCLUSION
Lower limb muscle strength, and physical performance can be improved and pain intensity can be reduced in patients with OA by performing aquatherapy three times a week for 8 weeks.

INTRODUCTION
Short stem prostheses were originally designed for younger and more active patients. In recent years, they have been increasingly offered to older patients. This study evaluates the mid-to long-term survival of a short stem prosthesis and the changes in periprosthetic bone density following implantation of a cementless short hip stem in patients over 60 years of age.
METHODS
118 patients aged over 60 received short stem prostheses. Clinical examination included Harris Hip Score (HHS) and Hip Disability and Osteoarthritis Outcome Score (HOOS). 93 patients were followed clinically for at least five years. 53 patients underwent dual-energy x-ray absorptiometry (DXA) and radiographic evaluation. Follow-up intervals were preoperative and postoperative (t), at approximately six months (t), at approximately two years (t), and at approximately five years or later (t).
RESULTS
Over a mean 6.7-year observation period for all 118 patients, one stem revision occurred due to a traumatic periprosthetic stem fracture. The five-year survival rate for the endpoint in 95 at-risk patients is 99.2%. HHS improved significantly from t 55.3 ± 11.5 (range 30-79) to t 95.3 ± 8.6 (range 57-100) at a mean of 8.0 years (p < 0.001). HOOS improved significantly in each subscale (p < 0.001). Bone mineral density (BMD) was available for review in 53 patients after a mean of 7.1 years. BMD increased from t to t in region of interest (ROI) 3 (+0.4%) and ROI 6 (+2.9%) and decreased in ROI 1 (-10.3%), ROI 2 (-9.8%), ROI 4 (-5.3%), ROI 5 (-3.4%) and ROI 7 (-23.1%).
CONCLUSIONS
The evaluated short stem prosthesis shows a remarkably high survival rate in elderly patients, accompanied by excellent clinical results. Load transfer measurements show a metaphyseal-diaphyseal pattern with a trend towards increased diaphyseal transfer over the period observed.

INTRODUCTION AND PURPOSE
Ensuring proper femoral component alignment post-Total Knee Arthroplasty (TKA) is crucial for normal patellofemoral (PF) kinematics. However, the customary 3° external rotation relative to the Posterior Condylar Axis (PC Axis) may not universally apply, and the expected final femoral component rotation remains unclear in functionally aligned knees. This study examines the relation between the Transepicondylar Axis (TEA) and PC axis, known as Posterior Condylar Angle (PCA) in Indian patients along with factors influencing PCA, and the feasibility of reproducing patient-specific PCA using image-guided Cuvis joint robot.
METHODS
Forty patients (52 Knees) with primary osteoarthritis and varus deformity were prospectively evaluated. Native PCA was determined using CT-based J planner. Pre-operative patellar shape, PF tilt, PF shift, final femoral component rotation (representing post-operative PCA), final patellar tracking, and post-operative functional and radiological assessment at 3 months were recorded.
RESULTS
Study participants averaged 64.3 years of age, with a female-to-male ratio of 23 to 17. Varus deformities varied, with IA2 being most prevalent, and sagittal plane deformities included fixed flexion (34.6 %) and hyperextension (44.2 %). The average PCA was 1.9° (range: 0°-7.3°), with most knees (41 out of 52) below 3°. The majority had Wiberg type 1 patellae, with pre-operative patellar tilt averaging 5.63°, reducing post-operatively to 4.43°. Most patients (37 out of 40) achieved excellent Knee Society functional scores at the 3-month mark. Complications included one case of delayed wound healing and one femoral array pin breakage. Notably, our study revealed a significant deviation in PCA from the commonly reported 3° in Western literature, underscoring the need for region-specific considerations in TKA planning.
CONCLUSION
PCA of our population is statistically different from customary 3° followed with jig system. Image guided Robotics helps to identify patients specific PCA and reproducing the same was more commonly possible in patients with reducible Varus deformity.

Review
BACKGROUND
Anterior cruciate ligament (ACL) rupture is a prevalent sports injury with rising rates attributed to increased population participation in sports activities. ACL rupture can lead to severe knee complications including cartilage damage, torn meniscus, and osteoarthritis. Current treatment options include conservative measures and surgical interventions. However, debates persist regarding the optimal approach.
PURPOSE
This analysis intended to compare the function, knee stability, and incidence rate of secondary surgery between conservative and surgical treatments in ACL rupture patients.
METHODS
A systematic search was performed via Embase, Ovid Medline, PubMed, Cochrane Library, Web of Science, and Google Scholar for reporting outcomes of conservative and surgical treatments after ACL rupture. The outcomes included patient-reported outcome measures (PROMs), knee stability, the need for secondary meniscal surgery, delayed ACL reconstruction surgery, and revision ACL reconstruction surgery. Outcomes were analyzed using mean differences or odd ratios (OR) with 95 % CIs.
RESULTS
11 studies were included with 1516 patients. For PROMs, our evidence indicated no differences in KOOS Pain, KOOS Symptoms, KOOS Sport/Rec, KOOS ADL, and KOOS QOL. (all p > 0.05). for knee stability, pivot shift (OR, 0.14; p < 0.001), Lachman test (OR, 0.06; p < 0.001), and tibia translation (p < 0.001) were evaluated, and the available evidence favored surgical treatment over conservative treatment. For the incidence rate of any secondary surgery after the first diagnosis, the surgical group showed a lower rate of meniscal surgery with statistical significance (OR, 0.37; p < 0.001). The average rate of revision ACL reconstruction is 5.80 %, while the rate of delayed ACL reconstruction after conservative treatment is 18.51 %.
CONCLUSION
Currently, there is insufficient empirical evidence to advocate a systematic surgical reconstruction for any patient who tore his ACL. This review found no differences in function outcomes between conservative and surgical treatments. Regarding knee stability and secondary meniscal surgery, the results prefer the surgical treatments. The occurrence rate of revision and delayed ACL reconstruction are non-negligible factors that must be fully understood by both surgeons and patients before choosing a suitable treatment.

Review
INTRODUCTION
Osteoarthritis (OA) is a common degenerative disorder of the synovial joints and is usually an age-related disease that occurs due to continuous wear and tear of the cartilage in the joints. Presently, there is no proven medical management to halt the progression of the disease in the early stages. The purpose of our systematic review is to analyze the possible metabolites and metabolic pathways that are specifically involved in OA pathogenesis and early treatment of the disease.
MATERIALS AND METHODS
The articles were collected from PubMed, Cochrane, Google Scholar, Embase, and Scopus databases. "Knee", "Osteoarthritis", "Proteomics", "Lipidomics", "Metabolomics", "Metabolic Methods", and metabolic* were employed for finding the articles. Only original articles with human or animal OA models with healthy controls were included.
RESULTS
From the initial screening, a total of 458 articles were identified from the 5 research databases. From these, 297 articles were selected in the end for screening, of which 53 papers were selected for full-text screening. Finally, 50 articles were taken for the review based on body fluid: 6 urine studies, 15 plasma studies, 16 synovial fluid studies, 11 serum studies, 4 joint tissue studies, and 1 fecal study. Many metabolites were found to be elevated in OA. Some of these metabolites can be used to stage the OA Three pathways that were found to be commonly involved are the TCA cycle, the glycolytic pathway, and the lipid metabolism.
CONCLUSION
All these studies showed a vast array of metabolites and metabolic pathways associated with OA. Metabolites like lysophospholipids, phospholipids, arginine, BCCA, and histidine were identified as potential biomarkers of OA but a definite association was not identified, Three pathways (glycolytic pathway, TCA cycle, and lipid metabolic pathways) have been found as highly significant in OA pathogenesis. These metabolic pathways could provide novel therapeutic targets for the prevention and progression of the disease.

Review
BACKGROUND
Exosomes are the smallest extracellular vesicles (30-150 nm) secreted by all cell types, including synovial fluid. However, because biological fluids are complex, heterogeneous, and contain contaminants, their isolation is difficult and time-consuming. Furthermore, the pathophysiology of osteoarthritis (OA) involves exosomes carrying complex components that cause macrophages to release chemokines and proinflammatory cytokines. This narrative review aims to provide in-depth insights into exosome biology, isolation techniques, role in OA pathophysiology, and potential role in future OA therapeutics.
METHODS
A literature search was conducted using PubMed, Scopus, and Web of Science databases for studies involving exosomes in the osteoarthritis using keywords "Exosomes" and "Osteoarthritis". Relevant articles in the last 15 years involving both human and animal models were included. Studies involving exosomes in other inflammatory diseases were excluded.
RESULTS
Despite some progress, conventional techniques for isolating exosomes remain laborious and difficult, requiring intricate and time-consuming procedures across various body fluids and sample origins. Moreover, exosomes are involved in various physiological processes associated with OA, like cartilage calcification, degradation of osteoarthritic joints, and inflammation.
CONCLUSION
The process of achieving standardization, integration, and high throughput of exosome isolation equipment is challenging and time-consuming. The integration of various methodologies can be employed to effectively address specific issues by leveraging their complementary benefits. Exosomes have the potential to effectively repair damaged cartilage OA, reduce inflammation, and maintain a balance between the formation and breakdown of cartilage matrix, therefore showing promise as a therapeutic option for OA.

Review
INTRODUCTION
Hip osteoarthritis (OA) is one of the leading causes of disability and morbidity worldwide. It is estimated to affect 9.2% individuals globally with age over 45 years. Conventional treatment modalities have limitations and side-effects. To overcome these limitations, over the last decade, there has been an increased interest in the use of orthobiologics derived from autologous sources including platelet-rich plasma (PRP), bone-marrow aspirate concentrate (BMAC) and adipose tissue derived formulations. This review qualitatively presents the in-vitro, pre-clinical, clinical and on-going clinical studies exploring the safety and efficacy of BMAC for management of hip OA.
MATERIALS AND METHODS
The electronic database search was done through PubMed, Embase, Web of Science, Scopus, ProQuest and Google Scholar till February 2024. The search terms used were "osteoarthritis" OR "hip osteoarthritis" OR "orthobiologics" OR "efficacy or use of orthobiologic treatment" OR "bone-marrow concentrate" OR "bone-marrow aspirate concentrate", AND "BMAC". The inclusion criteria were clinical studies of any level of evidence written in the English language, published till February 2024, evaluating the safety and efficacy of intra-articular administration of BMAC for the management of hip OA.
RESULTS
A total of 5 studies were included in this review for qualitative data synthesis. The total number of patients who participated in the study was 182, ranging from 4 to 112 in a single study. No adverse events were reported throughout the duration of the study. In addition, intra-articular administration of BMAC led to reduced pain, and improved function and overall quality of life (QoL).
CONCLUSION
The results from this review demonstrated that administration of BMAC is safe and potentially efficacious in terms of reducing pain, improving function and overall QoL of patients with hip OA in short- and mid-term average follow-up based on the included studies. Nonetheless, more adequately powered, multi-center, prospective, double-blind, non-randomized and randomized controlled trials with long-term follow-up are warranted to establish long-term safety and efficacy of BMAC for management of hip OA and justify its routine clinical use.

Review
INTRODUCTION
The knee is the most commonly affected joint in osteoarthritis (OA), affecting millions of people worldwide. Knee OA significantly impacts the activities of daily living (ADL) along with affecting overall quality of life of patients (QoL), thereby leading to substantial socio-economic burden. Conservative therapies are prioritized, resorting to surgery only when needed. However, these traditional approaches have limitations. Regenerative medicine, involving the use of orthobiologics, including autologous peripheral blood-derived orthobiologics such as growth factor concentrate (GFC), has evolved and shown potential for managing knee OA. The primary goal of this review is to summarize the results of in vitro, preclinical and clinical studies involving GFC for the management of knee OA.
METHODS
Multiple databases (PubMed, Scopus, Google Scholar, Web of Science and Embase) were searched applying terms for the intervention 'GFC' and treatment 'knee OA' for the studies published in the English language to March 10, 2024.
RESULTS
Only three clinical studies met our pre-defined criteria and were included in this review.
CONCLUSION
Intra-articular administration of GFC is safe and potentially efficacious to manage OA of the knee. More, adequately powered, multi-center, prospective, RCTs are warranted to demonstrate the long-term effectiveness of GFC in patients suffering from mild-to-moderate knee OA and to justify its routine clinical use. Further studies evaluating the efficacy of GFC compared to other orthobiologics are also required to allow physicians/surgeons to choose the optimal orthobiologic for the treatment of OA of the knee.
