Diagnostic Examination of Knee Injuries

The diagnosis of knee injuries is a complex process that begins with a thorough understanding of the circumstances surrounding the accident. For doctors, knowledge of the causes of injury and any previous conditions is essential in order to suggest appropriate treatment. The knee joint has an extremely complex structure, which is why various imaging and physical examinations are necessary to accurately determine the injuries. Establishing the correct diagnosis not only helps identify the type of injury but also plays a key role in planning the appropriate treatment.

After a knee injury, patients often experience swelling, pain, and limited movement. These signs indicate not only the extent of the injury but also the nature of the damage. Doctors decipher the problem using various tests and clinical examinations, but the diagnosis is made based on observations during physical examinations and the patient’s complaints. It is important that the examinations do not cause pain to the patient, as the ability to move the leg is essential for assessing the condition of the knee.

Physical examination to assess the condition of the knee

During the physical examination of the knee, the doctor first analyzes the symptoms described by the patient and then begins the palpation and movement examination of the knee. The location and nature of the swelling and pain provide crucial information about the type of injury. Doctors use various special tests that allow them to quickly, often within a few minutes, establish a diagnosis.

During the examination, the function of the knee ligaments, the range of motion, and stability are also evaluated. Doctors pay attention to ensuring that the examinations do not cause pain, and if there is suspicion of a more serious injury, they proceed cautiously before conducting further examinations. The physical examination alone is not sufficient to confirm the diagnosis; however, in most cases, it provides useful information about the extent and nature of the injury.

Joint fluid sampling and its significance

In cases of knee joint injuries, especially when a hematoma develops, it may be necessary to perform a joint fluid aspiration. This procedure serves not only diagnostic purposes but also has a pain-relieving effect. Removing the fluid reduces the pressure on the tissues, thereby alleviating pain, which is particularly important for the healing process.

During the analysis of the fluid sample, specialists can determine whether there is internal bleeding, which may indicate damage to the knee ligaments or bones. Additionally, if the sample contains fat tissue, it may also suggest a bone injury. Thus, this examination is extremely useful in confirming the diagnosis and can help in developing the appropriate treatment plan.

The role of imaging studies in diagnosis

If the physical examinations and joint fluid analysis raise suspicion of a severe knee injury, further imaging studies become necessary. X-rays are primarily used to detect bone fractures, so they are often performed after accidents. In contrast, magnetic resonance imaging (MRI) can assess the condition of soft tissues, such as menisci, cartilage, ligaments, and muscles.

CT scans can also be useful, as they provide a more detailed view of the knee joint and can help clarify the diagnosis. In special cases, such as after previous surgeries, additional procedures like SPECT/CT may be performed, which combine different imaging techniques to provide even more accurate information about the condition of the knee.

Arthroscopy: diagnosis and treatment in one

If a knee injury requires surgical intervention, arthroscopic examination plays a crucial role in establishing the diagnosis. This minimally invasive procedure allows specialists to directly visualize the internal structures of the knee. The significant advantage of arthroscopy is that it serves not only diagnostic purposes but also provides opportunities for treatment in many cases.

During the examination, the doctor can identify injuries and, if necessary, immediately perform the required interventions, such as treating damaged ligaments or cartilage injuries. This approach can significantly accelerate the healing process and reduce the risk of later complications. Arthroscopic diagnosis and treatment thus offer an effective solution for managing knee injuries, enabling faster rehabilitation and restoration of knee function.
