I shattered my tibia plateau on a dirt bike in my early 20’s, I’m 58 now. I skied on this knee for 30 years with out any compromise. I finally had it replaced three years ago, and I’m still skiing.
Similar story here. I had a tibial plateau at 29yo. Bone graft (only 2 screws) and meniscus repair. Had the hardware removed 10 months after original surgery. I was skiing about 3 1/2 months afterward and have continued to ski every season since. I'm now at 57yo and finally having it replaced.
