This case shows a constellation of findings in knee trauma: 

• peripheral radial tear of the PHMM. 
• medial femoral condyle osteochondritis dissecans (OCD) with subchondral edematous marrow signal as well as marrow edema signal of the lateral femoral condyle and posterior tibial plateau.
• high grade partial thickness tear of the medial collateral ligament.
• minimal joint effusion.

The morale is never get staisfied with a finding (satisfaction of search); once you get a finding, search for another.
