Second post in a row (there won't be eleven): just back from doc re. left knee. Diagnosis: mild to possible grade 1 strain of MCL; no lasting damage. Mild strain (not tear) of medial meniscus. No lasting damage. Recovery time (for an old man): another 3 to 5 weeks, all going well. Time to ride (easy gears only; no mashing etc.): in another 10 days of so if the knee feels up to it.
