Hamilton, NZ, in January 1979.
Keith has tried arthroscopy and various other treatments, and can walk without significant problems, but misses his running so much that he has booked in for a partial knee replacement next week. If you Google "running with a partial knee replacement", you can find instances of runners doing so successfully. You can also find a study that suggests no difference in knee replacement failure rates after seven years between two groups, one of whom exercised more vigorously than advised by their surgeons. However, I couldn't find any website where doctors recommended running, especially long-distance running, after a partial or total knee replacement.
