Following a medial femoral condyle osteochondral autograft mosaicplasty, which of the following statements best describes the fixation of the graft?
Graft fixation strength increases linearly with time until subchondral union at 3 months
Graft fixation strength initially decreases during the early healing phase, and then increases with subchondral bone healing
Graft fixation strength does not change during the first 3 months following surgery
Graft fixation strength is enhanced by early weight bearing
Graft fixation strength initially increases over the first 6 weeks, then recedes with bony remodeling
A 24-year-old female has moderate arthrosis of the medial facet of the patella and the medial femoral condyle. Which of the following procedures is contraindicated?
Anterior (Maquet) tibial tubercle osteotomy
Anteromedial (Fulkerson) tibial tubercle osteotomy
Anterolateral tibial tubercle osteotomy
Medial opening wedge high tibial osteotomy
Lateral closing wedge high tibial osteotomy
A patient with a symptomatic chondral defect undergoes the arthroscopic procedure seen in Figure A. The reparative tissue would best be described as which of the following?
A 32-year-old female is referred to you for definitive treatment of a symptomatic focal chondral defect on her medial femoral condyle. A photograph from a recent diagnostic arthroscopy shows the defect (Figure A), which measured 25 x 25mm after debridement. What surgical treatment would you recommend?
Osteochondral autograft with 1-2 plugs
All of the following are acceptable scenarios for the use of autologous chondrocyte implantation (ACI) in the patellofemoral joint EXCEPT:

HPI - 2 w ago patient felt intense (10/10) left knee pain while playing football without any obvious injury. Localized tender edema developed on his left upper tibila metaphysis on the medial side. After a short oral NSAID regimen and ice application his pain subsided almost completely (2/10). He underwent CT and MRI (+IV paramagnetic agent) examination
What is your opinion on cruciate ligaments integrity based on 02-21-2018 MRI sequences?
HPI - 36 year old active male with lateral knee pain. Previous hx of acl recon. Did well with that. Recently started to have lateral knee pain.
Initial arthroscopy did reveal Grade 3-4 lateral joint chondromalacia. Well contained lesions. This was debrided and microfractured. ACL graft was intact.
Continued to have pain. all pain is lateral knee.
Now my Plan is for ACI vs DeNovo.
Full length scanogram films shows mechanical axis falls through the lateral joint. Not terrible but not normal either.
Any indication for distal femoral osteotomy along with cartilage restoration? Stage or do at same time?
Plan of care?
HPI - Painless knee crepitus
What is the MRI finding?
