I fractured my knee, along with my femur (same leg) in 2007 in an RTC. I recovered well following a couple of operations. I began rehab and going to the gym soon after the accident and still enjoy training to this day. One thing I have noticed over the years, is that however hard I push it, my left quad will always be smaller than my right ("good" leg). I do get a pump, and there is clear muscle definition, but it's not quite the same. Obviously there is probably good reason for this, does anyone have this problem or know what the cause is? I am right handed/footed, so I guess there could always be an inherent weakness in my left leg, but there is no doubt my accident is also a cause. Any info would be appreciated.
