Chief Complaint (CC): A dull pain in both knees with occasional clicking in one or both knees and the sensation of the patella catching.
History of Present Illness (HPI): RF is a 15-year-old male who reports dull pain in both knees. Sometimes one or both knees click, and the patient describes a catching sensation under the patella. He states that the pain has been on and off for the last four months and initially only present after intense activity but has gotten worse since starting track this summer and seems to be present more often than before.
The patient states that the clicking comes and goes and isn’t always present in both knees at the same time. The catching sensation under the patella is more pronounced since he started doing the long jump in track. The patient states that he is able to bear weight as the pain is a dull ache. Icing his knees after sports and taking ibuprofen help to reduce the pain and swelling but both occur more frequently now making it difficult to participate in sports. The patient feels that he may be overdoing it with all of the sports he participates in and is worried about not being able to play soccer if it continues to get worse. The patient rates the pain 7/10 after intense activity.

Lab Tests and Results:
Erythrocyte sedimentation rate (ESR) – Normal
Passive extension-flexion sign- positive- which is tenderness on palpation of the tendon at the inferior pole of the patella.
McMurray test- Negative for locking during joint movement.
MRI- Showed high signal intensity within the proximal posterior central aspect of the tendon at its origin.
- Patellar tendinitis: This is the most likely diagnosis based on the patients HPI, ROS, physical assessment, and diagnostic studies. The patient’s chief complaint was a dull pain in the knees with occasional clicking in one or both knees. The patient is athletic and participates in many sports that continuously put a strain on his knees. The quadriceps angle was greater than ten which suggests patellar tendinitis. The patient plays sports that include a lot of running and jumping which adds strain to the knee joints. The patient was also positive for tenderness on palpation at the inferior pole of the patella bilaterally. Lastly, the MRI was positive for high signal intensity within the proximal posterior central aspect of the tendon where it originates from.
- Osgood Schlatter’s disease: A possible diagnosis as it is a common problem which typically occurs during times of fast growth usually in fit, active boys. Osgood Schlatter’s disease is associated with pain just below the kneecap in one or both knees, often worse after sports especially high impact activities using the quadriceps muscles. However, limping is often a present, and the patient denied limping in the ROS. Pain is greater with stair climbing and kneeling, and the patient did not admit to either. Flexion and extension will increase pain in the tibial tubercle which was not present upon physical exam of the patient.
- Chondromalacia patellae: This is a possible diagnosis due to the presence of knee pain upon palpitation and increased pain with activity. However, chondromalacia patellae are more common in females or persons with a history of knee trauma. The patient is male and denied trauma to either knee. The patient denied a history of misalignment which is also related to chondromalacia patellae. An x-ray of the knee would show irregularities of the patellofemoral joint.
- Medial meniscus tear: This diagnosis is a possibility because it can occur after a twisting injury and the patient participates in sports such as soccer, basketball, and skiing that involve twisting movements. Clicking may be present with a medial meniscus tear which the patient reported and was also appreciated upon physical assessment in the right knee. McMurray test was negative for locking during joint movement. The patient denied difficulty with weight bearing.
- Juvenile rheumatoid arthritis (JRA): Possible due to knee joint soreness and stiffness, however, both typically improve with activity. Joint swelling may also present with JRA and was reported by the patient in his ROS. The patient denied weight loss and fatigue which are common symptoms. The patient also denied night pain. A CBC would show anemia, leukocytosis, and thrombocytosis. The ESR would be elevated.
