With torn medial patello-femoral ligament and medial patella retinaculum. Note that impaction injury can occur almost anywhere at the lateral femoral condyle (although commonly anterolaterally).

Is intra-articular pathology associated with MCL edema on MR imaging of the non-traumatic knee?
Conclusions: We confirmed that MCL edema is associated with osteoarthritis, but is also associated with meniscal tears, meniscal extrusion, and chondromalacia. In addition, MCL edema can be seen in patients without intra-articular pathology, recent trauma or MCL abnormality on physical examination.

"CONCLUSION: Selective fatty atrophy of the ADQ is not a rare finding on MR examination
of the foot and ankle, being seen in 6.3% of all studies and in 7.5% of all studies in females.The clinical relevance of selective ADQ atrophy seen on MRI is uncertain."

Conclusion: Prevalence of fatty muscle atrophy of the ADM muscle—classically considered to represent entrapment neuropathy—is between 4% and 11% in both asymptomatic volunteers and patients with foot pain, and it increases with age.
