What exactly was the problem? And was it from an injury or just wear and tear?
-Bone on bone contact for 3.5 - 4 years.
-Limited and decreasing range-of-motion due to bone spurs.
-Involuntary change in my gait. It was becoming difficult to walk like a normal cat no matter how hard I tried (the pain didn't matter, I was starting to walk "differently".)
-I would often wake up at 3am/4a/5am because of the bone on bone pressure.
It was primarily wear and tear. There was no single incident of trauma. Keep in mind I am 49 years old and have a solid history of competitive powerlifting, cycling, wrestling & football (through High School ) bodybuilding, and while not competitive as a runner, I have run several (9) marathons and have completed several endurance events that probably didn't help my hip. Combine that with plenty of drinking and just raising hell. It's odd, I am right handed and therefore "right footed" so for all those years I would use my right leg as my stronger leg. The X-rays show my right hip to be in truly excellent condition. Strange.
Below is the same femoral head seconds after being cut from my femur. It looks much nicer here I think. The shiny strip down the center is a result of bone-on-bone contact for 3+ years. For reference, the doctor's bloody gloved index finger is touching at the top at the 1 o'clock position.
