Hayley, aged 11 years, is a grade 6 student who presents with her mother, Jenna, after an injury sustained during an Australian Rules Football match over the weekend. Hayley jumped up to contest a ball but felt a ‘pop’ in her right knee as she landed; she attempted to walk off the pitch, but she had to limp off with the assistance of her coach.
The knee was iced, and Hayley hopped to the car to return home. She reports that the knee is ‘swollen’ and ‘sore’ but that she has regained some movement over the past 24 hours. She is still unable to weight- bear through the right leg. 1.What further information would you gather on history-taking? 2.What tests would you include on examination of Hayley’s knee? 3.What are three likely differential diagnoses? What is the emergent management of Hayley’s right knee? 4.What views are required on initial X-ray, and what intra- articular pathology can potentially be identified? 5.What other imaging modalities would be appropriate now? 6.What is the significance of the fracture, and what are the management options for this injury? 7.What is the process of rehabilitation after treatment for ACL injuries? When can patients return to sport? 8.What is the most likely differential diagnosis, and what is the probability of occurrence? 9.What is the most likely differential diagnosis, and what is the probability of occurrence? #Week15_Case2
Douglas, aged 57 years, is a man who owns and runs a clothing store. He woke up three days ago with a painful, hot and swollen right knee. He has not experienced any trauma to the area. He has had gout in his left first toe previously but no issues with his knee. The pain is on the medial aspect of his knee and is worse when he walks or moves the knee. He has treated it so far with ice and by taking paracetamol, which has had minimal effect. Douglas is unable to work because of the knee pain. 1.What differential diagnoses would you consider? 2.How is a knee joint aspirate helpful in this setting? What would you specifically request on the pathology form and why? 3.Is ultrasonography helpful in the setting of atraumatic knee pain? 4.What are the four classic radiographic signs of osteoarthritis? 5.What X-rays would you order (ie what would you write on the request form)? 6.Regarding Douglas’ presentation and diagnosis, what measures would you put in place to manage his flare-up of osteoarthritis? 7.What impact does an elevated BMI have on knee osteoarthritis? 8.What other strategies would you recommend to maximise ongoing nonoperative management of osteoarthritis? #Week15_Case1
