It is impossible to comment on the specifics of your knee, but perhaps I can give you some general information. First, the microfracture surgery that you had, had NOTHING to do with your meniscus. It was to attempt to regenerate the articular cartilage in your patellafemoral joint. In general, microfacture has about80% success rate after 2 years, and the results deteriorate over time. In general, cartilage restoration procedures have better outcomes if the algnment issues that caused the problems are corrected as well. This istrue for MF, ACI and OATS. It sounds as if this has not been done for you. On option then, is a patella realignment procedure. I favor the procedure known as Fulkerson Procedure or anteromedialization of the tibial tubercle.
While joint replacement procedures are definitive, we like to avoid them in young patients when possible, because of the limitted longevity of the components. However, if your quality of life is poor and all other options have been exhausted. Knee replacement can be extremely effective. Whether, total knee, partial knee, or patellafemoral replacement is best can only be determined ny examining you and reviewing your xrays.
