Common Knee conditions - chronic

Question 1

Patellofemoral pain syndrome (PFPS)

Answer 1

Rule out/consider patella tendinopathy

MOI: Develops from chronic overload (e.g., excessive running load), poor knee biomechanics, abnormal anatomical alignement
(runners with a combinat° of >: Hip: ADD, IR, Ext; Knee: valgus, IR; Foot pronation; Ankle DF)

S&S: Mild to moderate pain over the PFJ that can be diffuse or vague

CA: Anterior knee/PFJ P°: squatting, climb stairs, running, jogging and/or hopping
Patella palpation (P°)
Knee Ext strength <

Grind/Clarke’s test

Question 2

Patella tendinopathy
“Jumper’s knee”

Answer 2

Difficult to distinguish from PFPS and may co-exist

RF/MOI: Common in repetitive jumping activities/sports; common among athletes and people who increase activity to quickly

S&S: Localised P° at patella tendon

CT: Patella tendon P° with: jumping, running, jogging and/or hopping
