Ultrasound Imaging in Knee Osteoarthritis: Current Role, Recent Advancements, and Future Perspectives

While conventional radiography and MRI have a well-established role in the assessment of patients with knee osteoarthritis, ultrasound is considered a complementary and additional tool. Moreover, the actual usefulness of ultrasound is still a matter of debate in knee osteoarthritis assessment. Despite that, ultrasound offers several advantages and interesting aspects for both current clinical practice and future perspectives. Ultrasound is potentially a helpful tool in the detection of anomalies such as cartilage degradation, osteophytes, and synovitis in cases of knee osteoarthritis. Furthermore, local diagnostic and minimally invasive therapeutic operations pertaining to knee osteoarthritis can be safely guided by real-time ultrasound imaging. We are constantly observing a growing knowledge and awareness among radiologists and other physicians, concerning ultrasound imaging. Ultrasound studies can be extremely useful to track the response to various therapies. For this specific aim, tele-ultrasonography may constitute an easy tool aiding precise and repeated follow-up controls. Moreover, raw radio-frequency data from US backscattering signals contain more information than B-mode imaging. This paves the way for quantitative in-depth analyses of cartilage, bone, and other articular structures. Overall, ultrasound technologies and their rapid evolution have the potential to make a difference at both the research and clinical levels. This narrative review article describes the potential of such technologies and their possible future implications.

Study on the effects of the use of therapeutic ultrasound in the treatment of osteoarticular diseases

Introduction. The use of therapeutic ultrasounds is a method that proved its efficiency in articu-lar and periarticular pathology, in the subacute and chronic stages. The biological effects of the ultrasound use are determined by their interaction with the cellular structures whereas the re-sults depend on the used parameters. The purpose of the survey is to evaluate / identify the ef-fects of using ultrasounds in the treatment of musculoskeletal conditions (lumbar discopathy), knee osteoarthritis). Material and method. The survey was conducted on an outpatient basis in a period of 7 months and it is of the longitudinal type. It included 151 patients diagnosed with low back pain and knee osteoarthritis. The evaluated parameters were: pain, functional skills, articu-lar rigidity and the quality of life. Results. The effects of the use of ultrasounds is found in the decrease of pain, the stiffness of the joints and the contracture of the muscles, as shown by the re-sults of several surveys. Our survey proves that the use of ultrasounds decreases pain and in-creases the functional skills, it influences the physical function more obviously in patients with knee osteoarthritis, which is an aspect found in others surveys. Discussion. The use of a complex ultrasound treatment (in the pulsed way to avoid thermal effects) and kinesiotherapy enabled in our research the decrease of the pain and of the rigidity in the joints, the increase of the function-al skills and the quality of life, whereas these obtained results are in accordance with those of others surveys. Conclusions. The use of the therapeutic ultrasounds can have the following ef-fects: the decrease of the pain and of the joint rigidity, the improvement of the physical capacity for daily activities and the improvement of the quality of life. The use of low intensity ultra-sounds can determine biological effects with actions for a short period or for an average one.

Therapeutic ultrasound for knee osteoarthritis: A systematic review and meta-analysis with grade quality assessment

BACKGROUND

Therapeutic ultrasound (US) is a widely used intervention in physical therapy to manage pain and to aid in the healing of soft tissue.

OBJECTIVE

This systematic review aimed to determine the effects of therapeutic US on knee osteoarthritis (KOA) symptoms.

METHODS

PubMed, MEDLINE, EMBASE, Google Scholar, and the Cochrane databases were searched from inception to April 2019. Randomized controlled trials (RCTs) involving adults with symptomatic KOA that compared therapeutic US with a sham or other control were included. The methodological quality of the trials was assessed at the study level using the Cochrane Risk of Bias tool. The quality of evidence at the outcome level- and overall- was assessed using GRADE methodology. Meta-analyses were conducted using random effects models, and heterogeneity was assessed using the I2 statistic.

RESULTS

Four studies (N = 234 participants) were eligible for inclusion in our primary analyses assessing therapeutic US versus sham. The methodological quality of the included RCTs ranged from moderate to very low. Treatment with therapeutic US resulted in small, statistically significant benefits for pain (approximate 9.6% improvement on a 0-100 visual analog scale [95% confidence interval: 2, 17.4%]) and self-reported measures of function (approximate 12.8% improvement on a 0-100 visual analog scale [0.4, 25.2%]). The overall quality of the evidence was very low. No adverse events were reported in any of the included studies.

CONCLUSIONS

The use of therapeutic US may provide additional benefits to physical therapy regimens in terms of symptom relief in individuals with KOA. However, it is not possible to make any meaningful recommendations for clinical practice due to the small number of applicable RCTs and the low methodological quality of the RCTs deemed eligible for this study.
