Looking for thoughts on management of this patient. 53 year ol | MedRophine Science

Looking for thoughts on management of this patient. 53 year old pathologist with BMI 32 who presented to me 3 months ago with acute onset knee pain. Plain films showed some patellofemoral arthrosis. MRI at that time showed what looked like major stress reaction in medial femoral condyle and some changes in the medial meniscus and mild cartilage wear in the medial compartment. We unloaded him for 6 weeks and he did well with almost normal resumption of activity. Then recurrent acute onset of severe weight bearing pain medially. Repeat MRI shows what looks like a subchondral insufficiency fracture, worsening medial compartment cartilage thinning and patellofemoral arthritis. ACL intact. Full range of motion.
Question?????
Is he a good candidate for a medial uni with the patellofemoral cartilage loss of all of his oain is medial and he did no
