I am getting over two knee surgeries this last year, one ACL reconstuction and lateral release followed by a ACL revision and a PCL reconstruction along with alot of meniscus work. Due to the damage I inflicted on myself, the doc allowed me to ride road, but no mountain last summer and fall, I've rehabed my knee and was approved to ride on the mountain again for this upcomming spring and summer. I ride clipless on road (crankbros candys) but I am somewhat hesitant on going back to riding clipless on the mountain I am leaning to platforms. I am looking for both postitive and negative for clipless and platform, I know that there are tons of threads about pedal selection but I am hoping to hear from persons who have experienced knee surgery and how it impacted their pedal selection. Thank you for your input. JK
