Knee osteoarthritis (OA) is one of the leading causes of disability among the elderly population. This degenerative joint disease is characterized by progressive damage to the articular cartilage and structural alterations of the knee joint, resulting in pain, reduced mobility, and diminished quality of life. This Community Service Program (PKM) aimed to promote early detection of knee OA through simple radiological screening as a preventive strategy to reduce the risk of musculoskeletal disability. The activity was conducted at Asisi Church, South Jakarta, involving 87 participants aged 54–87 years (mean 70.77 ± 7.32 years). Radiological examination was performed using standard anteroposterior knee X-rays, and results were classified according to the Kellgren–Lawrence grading system. Findings revealed that 98.9% of participants exhibited radiological signs of OA, predominantly grade II (60.9%), followed by grade III (21.8%), grade I (11.5%), and grade IV (4.6%), while only 1.1% showed normal results. Female participants (74.7%) predominated across all OA grades, indicating hormonal and biomechanical influences on disease progression. The mean age increased with OA severity, supporting the degenerative theory that aging leads to decreased chondrocyte function and cartilage elasticity. In addition to screening, participants received education on weight management, muscle strengthening exercises, and injury prevention. The results demonstrate that simple radiological screening is an effective, practical, and cost-efficient community-based approach for early detection of knee OA. Integrating such preventive strategies within primary care systems could significantly reduce the burden of disability among the elderly population.

Background: Osteoarthritis is a degenerative disorder that occurs in the articular cartilage characterized by reduced synovial joints, the formation of osteophytes, damage to the ligaments and changes in the bones. The cause of osteoarthritis in the area of Puskesmas Banyuanyar is 46% of the population in one card families still have families who smoke and as much as 22% of people do not do physical activity due to the busy and physical condition. Objective: This investigation was carried out in an effort to improve knowledge on the case of osteoarthritis in the area of Puskesmas Banyuanyar. Method: This activity is a form of dissemination using leaflet media. To find out the results of improved understanding researchers conduct evaluations of pre-implementation and post-implementation. Results: Public dedication through this method of dissemination resulted in increased knowledge in the case of osteoarthritis from the average value of knowledge of 4,4% to 97,6%. Conclusion: Based on the results of the implementation of public service activities such as efforts to improve knowledge in case of osteoartritis, there was an increase in knowledge in PKK community

Osteoarthritis of the knee in the elderly can cause pain due to the degradation of joint cartilage in which the joint cartilage is damaged which is characterized by changes in the joint capsule and damage to the cartilage located at the bone joints. Knee Pain Exercise and warm compresses are two methods that can be used to manage knee osteoarthritis pain.. The purpose of this study was to analyze the effectiveness of knee pain exercise and warm compresses on reducing knee osteoarthritis pain in the elderly. Using a purposive sampling technique, a sample of 40 respondents was drawn from the population of up to 125 people. A cross-over group design technique and a quasi-experimental approach were used in the research design. The instrument used was a Numeric Rating Scale (NRS) observation sheet. The normality of the data was tested using the Kolmogorov-Smirnov. The hypotheses were tested and analyzed using paired samples T test with p-value 0.000 on each variable which means that there is an effect of knee pain exercise and warm compresses on knee osteoarthritis pain. The effectiveness test used independent samples test and it was found that warm compresses had the smallest mean value (2.55), which means that warm compresses were more effective in reducing knee osteoarthritis pain than knee pain exercise. It is expected that the elderly who experience knee osteoarthritis pain do regular exercise which is a physical exercise to reduce knee osteoarthritis pain.
