Ultrasound
Doctor, if there is an issue with the knee cartilage, can an ultrasound examination determine the condition?

Dr. Zhou Lizhi reply Orthopedics
Orthopedic ultrasound examination primarily diagnoses and treats soft tissue lesions and cannot differentiate knee cartilage lesions.
If there is indeed a knee cartilage lesion, an arthroscopic examination of the knee should be performed.
Our hospital currently has complete arthroscopic equipment for knee procedures, and we welcome you to visit our orthopedic outpatient clinic for further evaluation and treatment.

Ultrasound is a valuable tool in the assessment of various musculoskeletal conditions, including knee injuries. However, when it comes to diagnosing cartilage issues specifically, its effectiveness is limited. The primary role of ultrasound in knee examinations is to evaluate soft tissue structures, such as ligaments, tendons, and muscles, rather than the cartilage itself.
Knee cartilage problems, such as chondromalacia (softening of the cartilage) or cartilage tears, are typically best assessed using imaging modalities that provide a clearer view of the cartilage structure. Magnetic Resonance Imaging (MRI) is the gold standard for evaluating cartilage integrity because it offers high-resolution images of both soft tissues and cartilage. MRI can reveal subtle changes in cartilage thickness, surface irregularities, and other pathological conditions that ultrasound may not detect.
In your case, if there is a suspicion of knee cartilage issues, an ultrasound may not provide the definitive answers needed. While ultrasound can help identify associated soft tissue injuries, such as ligament tears or effusions (fluid accumulation), it is not designed to visualize cartilage in detail. Therefore, if cartilage pathology is suspected, further imaging with MRI is recommended.
Additionally, it is important to consider the clinical context when interpreting imaging results. Symptoms such as knee pain, swelling, and mechanical symptoms (like locking or catching) can indicate underlying cartilage issues. A thorough clinical examination, combined with appropriate imaging, will provide a more comprehensive understanding of the knee's condition.
In summary, while ultrasound can be useful for assessing certain aspects of knee injuries, it is not the most effective method for diagnosing cartilage problems. If you suspect cartilage damage, it is advisable to discuss the possibility of an MRI with your healthcare provider for a more accurate diagnosis and appropriate treatment plan.
