For knee pain, how predictive is physical examination for meniscal injury?
The bursae provide cushioning and reduce friction between the bones and the overlying soft tissue structures, such as tendon, muscle, and fat. Inflammation in the bursae in this area may cause pain or swelling in the front of the knee. Injury Something as simple as walking into a hard object may cause damage and bruising of the front of the knee. This can result in pain and tenderness at the site of impact.
Physical Examination of the Knee
Major trauma, such as from falls or vehicle accidents, may also cause knee damage, resulting in significant pain and disability. Although minor injuries are generally temporary, if a person is concerned about their symptoms, it is best to visit a doctor for a full examination. Several symptoms are associated with pain in the front of the knee, such as: pain when squatting or when climbing stairs pain while running or jogging pain in the front of the knee after sitting with the legs bent for long periods of time hearing popping or cracking sounds when bending the knee stiffness, especially when first waking up swelling in the front of the knee bruising around the knee the knee giving out or buckling under pressure A person should always make note of any symptoms they experience and report them to their doctor during examination.

Each symptom may help the doctor identify the underlying cause of the knee pain and make the correct diagnosis. Diagnosis A doctor will conduct a physical exam of the knee and ask the person about their symptoms. They will also test the range of motion and stability of the knee and check for any signs of structural damage to the joint. Other tests that may help them establish the correct diagnosis include: X-ray scans.

DOI: Data sources: MEDLINE searches were performed, as were reviews of various musculoskeletal examination textbooks that describe physical examination maneuvers of the knee. These references were then reviewed for additional references and crossed back to the original description when possible of these named tests. Study selection: All articles that discussed the sensitivity and specificity of the physical examination maneuvers were extracted. This information was reviewed for accuracy and then summarized.
The Blood Meals
Data extraction: Multiple MEDLINE and text searches were performed by using the terms of the test maneuver, the joint tested, and the term physical examination. Any article with this information was reviewed until the article describing the original description was found. Articles dating from that original article to the present were reviewed for information on the sensitivity and specificity of the test. Data synthesis: Literature reviewing the sensitivity and specificity of the tests reviewed is summarized in text and table form.
Common Knee Tests in Orthopedic Examination
The Lachman test seems to be very sensitive and specific for the detection of anterior cruciate ligament tears. For posterior cruciate ligament tears, the posterior drawer test is also very sensitive and specific and is enhanced with other tests, such as the posterior sag sign. For meniscal tears, the McMurray test is very specific but has a very low sensitivity, whereas joint line tenderness has fairly good sensitivity but lacks good specificity. Although collateral ligament testing seems to be sensitive and specific, there is a lack of well-designed studies that scientifically validate the sensitivity and specificity of these tests.
Comprehensive Physical Examination for Instability of the Knee
Common tests for patellofemoral pain and patellar instability lack sensitivity when correlated with pathologic operative findings. Conclusions: Most physical examination tests could be referenced back to an original description, with variable information on the sensitivity and specificity along with other information about the validity of these tests in clinical practice.

Physical Examination of the Knee Exam Overview A complete knee examination is always done for a knee complaint. Both of your knees will be checked, and the results for the injured knee will be compared to those of the healthy knee. Your doctor will also check that the nerves and blood vessels are intact. Your doctor will: Inspect your knee visually for redness, swelling, deformity, or skin changes. Feel your knee palpation for warmth or coolness, swelling, tenderness, blood flow, and sensation. Test your knee's range of motion and listen for sounds. In a passive test, your doctor will move your leg and knee joint. In an active test, you will use your muscles to move your leg and knee joint. At the same time, your doctor will listen for popping, grinding, or clicking sounds. Check your knee ligaments , which stabilize the knee.
Knee Examination
Tests include: The valgus and varus tests, which check the medial and lateral collateral ligaments. In these tests, while you lie on the examining table, your doctor places one hand on your knee joint and the other on your ankle and moves your leg side to side. The posterior drawer test, which checks the posterior cruciate ligament. In this test, you lie on the table with your knee bent at a degree angle and your foot flat on the table. Your doctor will put his or her hands around the top of your leg just below your knee and push straight back on your leg. The Lachman test, which checks the anterior cruciate ligament ACL. In this test, while you lie on the table, your doctor will slightly bend your knee and hold your thigh with one hand.

With the other hand, he or she will hold the upper part of your calf and pull forward. The Lachman test diagnoses a complete ACL tear. The anterior drawer test, which checks the ACL. Your doctor will put his or her hands around the top of your leg just below your knee and pull straight back on your leg. A pivot shift test, which checks the ACL. In this test, the leg is extended and your doctor holds your calf with one hand while twisting the knee and pushing toward the body.

It is often done just before a knee arthroscopy and after anesthesia has completely relaxed the muscles. A McMurray test may be done if your doctor suspects a problem with the menisci based on your medical history and the above exams. In this test, while you lie on the table, your doctor holds your knee and the bottom of your foot. He or she then pushes your leg up bending your knee while turning the leg and pressing on the knee. If there is pain and the sound or feeling of a click, the menisci may be damaged. Arthrometric testing of the knee may also be done. In this test, your doctor will use an instrument to measure the looseness of your knee. This test is especially useful in people whose pain or physical size makes a physical exam difficult.
History and Physical Exam of the Knee
An arthrometer has two sensor pads and a pressure handle that allows your doctor to put force on the knee. The instrument is strapped on to your lower leg so that the sensor pads are placed on the knee cap and the small bump just below it tibial tubercle. Your doctor then measures pressure by pulling or pushing on the pressure handle. Your exam may also include other tests to assess the degree of the injury and to identify damage to other parts of the knee. Why It Is Done A complete physical exam of the knee is always done for a knee complaint, whether the complaint is from a recent or sudden acute injury or from long-lasting or recurrent chronic symptoms.
Knee Physical Exam - Adult
Results In general, in a normal knee exam: The knee has its natural strength. The knee is not tender when touched. Both knees look and move the same way. There are no signs of fluid in or around the knee joint. The knee and leg move normally when the ligaments are examined. There is no abnormal clicking, popping, or grinding when knee structures are moved or stressed. The toes are pink and warm, and there is no numbness in the lower leg or foot. If any of these findings are not true-for example, the knee is tender-you may have a knee injury. But the results of a knee exam vary depending on whether the exam is for a sudden injury to the knee or for long-term symptoms and also depending on how long it has been since the injury occurred. An abnormal finding does not always mean that your knee is injured. Your doctor will use the results of the exam, plus your medical history, to make a diagnosis. What To Think About These tests provide the best information if there is little or no knee swelling, you are able to relax, and your doctor is able to move your knee and leg freely.
Evaluation of Knee Pain: An Urgent Care Approach
If this is not the case, it may be difficult to accurately check your knee. If your knee is red, hot, or very swollen, a knee joint aspiration arthrocentesis may be done, which involves removing fluid from the knee joint. This is done to: Help relieve pain and pressure, which may make the physical exam easier and make you more comfortable. Check joint fluid for possible infection or inflammation. See if there is blood in the joint fluid, which may indicate a tear in a ligament or cartilage. See if there are drops of fat, which may indicate a broken bone. Local anesthetic may be injected after aspiration to reduce pain and make the exam easier. If you are going to have arthroscopy, the knee may be examined in the operating room before the procedure, while you are under general or spinal anesthesia. Blahd, Jr.

Risk factors for tendon rupture include recent fluoroquinolone use, steroid use, DM, RA. Patient cannot SLR. Palpation of a suprapatellar groove if the patella has shifted in position. A lateral X ray may show the patella in a high riding position alta or a low riding position baja , measured formally by the Insall-Salvati ratio. A sunrise view may show patellar fractures. Dislocated knee High impact trauma Laxity in multiple ligaments. Most knee dislocations spontaneously reduce by the time the patient arrives to the emerg, however a reduction does not exclude vascular injury. Neurovascular exam and possible ancillary investigations are required as there is a risk of limb-threatening popliteal injury. Consider imaging for assessment of associated fractures.

Fracture Inability to weight bear, pain, swelling. Usually seen on X-ray, but a CT may be required to appreciate non-displaced fractures. Atraumatic Patellofemoral pain Overuse syndrome, often linked to weakness of the quadriceps muscle. May be associated with other overuse syndromes including chondromalacia patellae, medial plica syndrome, Iliotibial band syndrome lateral knee pain , popliteus tendinitis posterior knee pain.

Pain with firm compression of the patella. No mechanical symptoms eg, locking, catching. Commonly seen in young active female with high Q angle, as this increases the risk for patellar subluxation. Clinical diagnosis, X rays are often normal. Restricted ROM, crepitus. X rays may show joint space narrowing, hypertrophic osteophyte formation and cystic changes but radiographic changes are not necessarily correlated to clinical symptoms. Crystal arthropathy No other infectious symptoms. Unilateral, swollen joint, may have fever. Crystals in synovial fluid AND a negative culture, as the presence of crystals can be co-morbid with septic arthritis.

Septic arthritis Infection from hematogenous spread, open wound, or local spread through the joint space. Unilateral, hot, swollen joint. Fluid is typically opaque and yellow with a positive culture. Pre-patellar effusion, tender to palpation. May mimic a joint effusion or a septic knee. Ultrasound may help differentiate between bursitis and a joint effusion. Aspiration is required if there is any suspicion of infection. Systemic disease ex. Rheumatoid Arthritsi Known history of disease of systemic symptoms including fever, chills, night sweats, fatigue, or unintentional weight loss.

Insidious onset pain with morning stiffness. Management The vast majority of knee injuries can be managed conservatively using RICE restricted activity, ice, compression, and elevation. Topical therapies ex. Patients with suspected ligamentous injuries can be encouraged to weight bear as tolerated within limits of pain, using crutches as-needed for support. In the case of significant instability the patient should be non-weight bearing but should engage in daily ROM. Avoid immobilization with a Zimmer splint for ligamentous injuries as its use can delay rehabilitation, and contribute to atrophy and joint stiffness. Only patients with a soft tissue injury involving a quadriceps tendon rupture, patella tendon rupture, patellar dislocation, or fractured patella require a Zimmer immobilizer. Fractures should be immobilized, referred to orthopaedics, and patients should refrain from weight bearing.

Glucosamine and chondroitin are not recommended. On your assessment she has a large effusion that limits her ROM. You order an X-ray as she is unable to weight bear, and you see a small Segond fracture. She is diagnosed with an ACL tear and discharged home with suggestions for pain control, crutches, and advised to begin ROM exercises early. This young patient should be referred to orthopaedics for consideration of ACL repair before or after her MRI depending on local practice. ACL repair is generally delayed until near full ROM returns and the effusion resolves although this is surgeon dependent. In summary for acute knee injuries take a good history, avoid examining the patient in a chair, ensure appropriate follow-up and discharge instructions including encouraging active ROM and weight bearing as tolerated for ligamentous and meniscal injuries.

Accessed May 29, Reviewing with the Staff The knee is my favorite joint, the anatomy is easy to understand and you can usually make a diagnosis in the ED with a good history and physical exam. This case represents a very common presentation of an acute traumatic knee injury. Remember to examine the joint above and below; a hip injury can masquerade as knee pain and a proximal fibular fracture can be a Maisonneuve fracture that is associated with an ankle eversion injury.

It is also important to examine the patient supine, examining a knee in a chair or wheelchair which is tempting in a busy ED with a shortage of beds! Soft tissue injuries ligamentous and meniscal should not be immobilized in a Zimmer splint as this can contribute to stiffness, atrophy and delay rehabilitation. Active ROM should be encouraged for all ligamentous injuries including ACL tears as well as weight bearing as tolerated unless there is significant instability. Crutches are provided for support. The patient will need follow up for reassessment and an outpatient MRI for a definitive diagnosis. ACL repair is generally delayed until near full ROM returns and the effusion resolves although this is surgeon dependant.

Tricks and tips for physical examination of the multiligament injured knee: what we can not forget
Kneecap Problems Determining the cause of knee pain relies on a proper examination of the knee joint. Learn about how your doctor can examine your knee to determine the source of your knee pain, and what tests can be performed to make the diagnosis. However, not everyone knows there is excess fluid in the knee joint. Your doctor may compress the joint to feel for excess fluid. Fluid in the knee can often be visible above the kneecap and can be compressed in this area. Fluid is also often detected in the back of the knee, which if collected into a pocket of fluid is often referred to as a Baker's cyst. Deformity: As the knee cartilage is worn away, the knees may become progressively knock-kneed or bow-legged.

Limited motion: The range of motion of the knee typically becomes limited if arthritis, bone spurs, and swelling prevent normal mobility. Torn Meniscus Tests used to determine if there is a meniscus tear include: Joint line tenderness: Joint line tenderness is a very non-specific test for a meniscus tear. The area of the meniscus is felt, and a positive test is considered when there is pain in this area. McMurray's test : McMurray's test is performed with the patient lying flat on his back and the examiner bending the knee. A click can be felt over the meniscus tear as the knee is brought from full flexion to full extension. With the knee slightly bent, the examiner stabilizes the thigh while pulling the shin forward. A torn ACL allows the shin to shift too far forward. Anterior drawer test : This test is also performed with the patient lying flat on his back. The knee is bent 90 degrees and the shin is pulled forward to check the stability of the ACL.

Pivot shift test: The pivot shift test can be a difficult maneuver to perform on a patient, especially if they are having discomfort and not able to relax the knee. This test places stress on the knee joint that assesses the rotational stability of the ACL. Common Types of Sports Injuries Other Ligament Injuries For supected injury to other ligaments, including the posterior cruciate ligament PCL , medial collateral ligament MCL , and lateral collateral ligament LCL , these tests may be done: Posterior drawer test : The posterior drawer is performed similarly to the anterior drawer test. This test detects injury to the posterior cruciate ligament PCL. By pushing the shin backward, the function of the PCL is tested. With the patient lying flat, and the knee held slightly bent, the shin is shifted to each side.
Physical Examination of the Knee
Thorough examination of all of the knee structures, including the ligaments and menisci, should be included in every knee evaluation. The examiner must rely on numerous physical exam maneuvers to evaluate these structures. It is crucial not only that these maneuvers are performed correctly but also that the examiner is aware of the sensitivity and specificity of the various tests, as well as the limitations of the tests, to make the most accurate diagnosis possible. In this chapter, we provide a review of the physical examination of the knee followed by a literature-based review of the diagnostic accuracy of the major provocative tests used to diagnose knee injuries.
