“…In the present study, where patients with unilateral knee OA were included, cutaneous temperature of the anterior joint region of the knee was the only variable presenting a sig nificant difference between affected and unaffected knees. This must have been due to an increase in local catabolic ac tivity in the affected knee, as highlighted by Brito et al [19].…”

“…A recent study [19] aimed at verifying cutaneous tem perature of lower limbs in persons with knee OA and healthy individual observed that male patients tend to present a higher temperature in the thigh, and lower in the knee when compared to the control group.

“…However, the author of this study evaluated pain by questionnaires (Knee Pain Scale and WOMAC pain subscale) [17]. As the mechanisms of pain in OA are still not fully established and understood [3,4], precise methods such as ther mography and the objective evaluation of pain through pressure pain thresholds (a technique already employed by previous studies) [18,19] can bring information about the relationship between pain and cutaneous tempera ture in this disease. Although thermography is a reli able diagnostic tool to detect quantifiable cutaneous temperature patterns in patients with OA [18], a recent study highlights the fact that current scientific literature is still scarce about the employment of this technique in OA [19].…”

Introduction: Osteoarthritis is a common disease in which skin temperature may be included among the pathophysiological factors. Thermography allows the mapping of cutaneous tempera ture and may be employed in the investigation of osteoarthritis. Objectives: To evaluate cutaneous temperature of the lower limbs, as well as to verify its associa tion with pressure pain thresholds in individuals with knee osteoarthritis. Material and methods: This case series study was conducted with individuals of both genders aged 48-77 years with unilateral knee osteoarthritis. Volunteers underwent thermographic evalua tion by an infrared sensor (FLIR T650SC). The anterior region of the thigh and leg and the knee area were evaluated. Pressure pain thresholds (PPT) were evaluated by algometry (Pain Diagnostics, Great Neck, USA) at the vastus medialis, vastus lateralis, rectus femoris, and patellar tendon. Data analy sis was conducted with the statistical package SPSS v.24 for Windows. Comparisons between affected and unaffected sides were made by paired Student's ttest or the MannWhitney U test, and associations between variables were assessed by Pearson or Spearman's correlation coefficient. In all cases, the significance level was set at p ≤ 0.05. Results: Eleven volunteers (63.1 ±9.5 years) participated in this study. When comparing cutaneous temperature, only the region of the knee showed a significant difference between sides (p = 0.02). There were no differences between affected and unaffected knees regarding pain tolerance (PPT) at all sites evaluated. There were also no significant associations between the study variables. Conclusions: Individuals with knee osteoarthritis presented a higher temperature of the affected knee, but this was not associated with pressure pain thresholds.

Objective Inflammation plays a central role in the pathophysiology of rheumatic diseases as well as in osteoarthritis. Temperature, which can be quantified using infrared thermography, provides information about the inflammatory component of joint diseases. This systematic review aims at assessing infrared thermography potential and limitations in these pathologies. Design A systematic review was performed on 3 major databases: PubMed, Cochrane library, and Web of Science, on clinical reports of any level of evidence in English language, published from 1990 to May 2021, with infrared thermography used for diagnosis of osteoarthritis and rheumatic diseases, monitoring disease progression, or response to treatment. Relevant data were extracted, collected in a database, and analyzed for the purpose of this systematic review. Results Of 718 screened articles 32 were found to be eligible for inclusion, for a total of 2094 patients. Nine studies reported the application to osteoarthritis, 21 to rheumatic diseases, 2 on both. The publication trend showed an increasing interest in the last decade. Seven studies investigated the correlation of temperature changes with osteoarthritis, 16 with rheumatic diseases, and 2 with both, whereas 2 focused on the pre-post evaluation to investigate treatment results in patients with osteoarthritis and 5 in patients with rheumatic diseases. A correlation was shown between thermal findings and disease presence and stage, as well as the clinical assessment of disease activity and response to treatment, supporting infrared thermography role in the study and management of rheumatic diseases and osteoarthritis. Conclusions The systematic literature review showed an increasing interest in this technology, with several applications in different joints affected by inflammatory and degenerative pathologies. Infrared thermography proved to be a simple, accurate, noninvasive, and radiation-free method, which could be used in addition to the currently available tools for screening, diagnosis, monitoring of disease progression, and response to medical treatment.

“…They captured the thermal images of the knee with frontal projection and found that the Tsk of the patellar region correlated with X-rays findings. Besides diagnosis, thermography has been used to evaluate the changes in Tsk of OA patients in response to training session [17]. The authors have reported the knee Tsk of patients increased significantly after the exercise when compared to the control subjects.…”

Radiography is a widely used method for grading and tracking the anatomical changes in knee osteoarthritis (OA) patients. The ease of thermography in mapping functional information via the skin temperature (Tsk) helps in the diagnosis of various musculoskeletal diseases. There is a significant involvement of soft tissues in knee OA due to the complex osteoligamentous degeneration, which may affect the knee Tsk. A total of 62 patients with knee OA were analysed using thermography. The mean Tsk was computed by extracting the region of interest from the acquired thermal images using an automatic segmentation technique for frontal, lateral, and medial views. The mean Tsk for grade 1, 2, 3 and 4 were 30.96 ± 0.59, 31.56 ± 0.79, 31.40 ± 1.22, 32.20 ± 0.70˚C respectively. A significant temperature difference was found between grade 2 and 4 (p = 0.02, p = 0.018), grade 3 and 4 (p = 0.03, p = 0.02) for frontal and lateral views; whereas no significant difference was found between grade 2 and 3. Further, 2-way ANOVA test showed that risk factors (like age, BMI and duration of disease) do affect the mean Tsk significantly with a p-value of 0.0003, 0.02, and 0.008. INTRODUCTIONAccording to the world health organization, 9.6% of men and 18% of women over the age of 60 years are affected by Osteoarthritis (OA) [1]. OA is a degenerative disease, where the cartilage of the joints, such as the knee, hip, toe, and fingers deteriorate with time. Although Kellgren and Lawrence (KL) method is the most commonly used grading system for knee OA, however, it has poor objectivity [2]. In a recent study, Gonçalves et al. while reporting on reliability testing for grading of OA using the KL method showed conflicting results [3]. The study reported that the level of agreement in the inter observer analysis was superficial. In contrast to radiography, the thermography captures the infrared (IR) radiations emanated from the body surface and provides the map of skin temperature (Tsk).It is a non-radiative, non-invasive, and non-contact imaging modality. A bone is a highly vascular structure that can lead to high blood flow due to bone remodelling in osteoarthritis [4][5][6].Unlike radiology which only captures structural changes, ther-This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
