Respond to at least two of your colleagues on 2 different days who were assigned different case studies than you. Analyze the possible conditions from your colleagues’ differential diagnoses. Determine which of the conditions you would reject and why. Identify the most likely condition, and justify your reasoning.

Differential Diagnosis (DDx):
1. Osgood-Schlatter Disease: A common cause of knee pain in growing adolescents. It is an inflammation of the area just underneath the knee where the ligament from the patellar tendon attaches to the tibia. It is most often happening during growth spurts, when bones, muscles, tendons, and other structures are rapidly changing. Because physical activity puts additional stress on bones and muscles, for example, children who partake in athletics — especially running and jumping are at an increased risk for this condition. However, less active adolescents might as well experience this issue. (American Academy of Orthopedic Surgeons, 2018).
2. Patellar tendonitis: Patients with overuse of the legs has a probable comorbidity (Rebella, 2015).
3. Patellar instability: Knee catching or “clicking” with movement, pain, excessive patellar movement (Mahmoud, 2016).
4. Left Osteochondritis Dissecans: Pain, left knee (Jones & Williams, 2016).
5. Left Medial Meniscus Tear: Clicking in the knee noted on exam, pain (Dains, Baumann, & Scheibel, 2016).
