A new standard radiographic reference for proximal fibular height in children.

abstract：BACKGROUND:Degree of satisfaction with a knee arthroplasty is said to be correlated to reduced pain and better function. During a validation of the Swedish Knee Arthroplasty Register in 1997, previously operated patients were asked how satisfied they were with their knee. A subgroup of "satisfied" patients was identifi...
