https://community.usms.org/swimming/f/general/9002/breaststroke-with-replaced-kneesI started swimming again about a year ago (after a 45 year layoff). For the past 6-8 months I have been doing 12-15000+ yards a week, almost all breaststroke, lots of repeats.

I think I have some rotation in my ankles, maybe 40-60 degrees.<div style="clear:both;"></div>https://community.usms.org/thread/141780?ContentTypeID=1Tue, 23 Mar 2010 08:28:06 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:620686f2-8874-4f4c-9bd2-c2f99a43d4f3Allen StarkI am not sure what you mean by can&#39;t bend past 90 degrees.Do you mean you can&#39;t flex the knee joint more than that or you can&#39;t externally rotate your ankles.Without knowing I can&#39;t comment.I definitely think you are starting off with too much breaststroke.I&#39;d ease into it more,no more than 200 BR at a time at first with the rest other strokes.If your shoulders are an issue do BR pull with dolphin kick with fins.<div style="clear:both;"></div>
