简要总结
The objective of this study is to analyze subjects having a normal hip and compare the in vivo kinematics to subjects requiring a total hip arthroplasty (THA) due to having a diseased hip and then later post-operative to their implanted hip. Ten subjects will have a normal hip, ten hips will be diseased, requiring a THA and then those ten diseased hips will be re-analyzed at least six months post-operatively after implantation of a THA.

结局指标
主要结局
Magnitude of Hip Separation During Primary Heel Strike
时间窗: Approximately 2 years postoperatively.
Negative values indicate hip compression, position values indicate hip separation. All "Diseased Hip" subjects were re-analyzed approximately 2 years postoperatively to yield the "Implanted Hip" group.
Magnitude of Hip Separation During Primary Toe Off
时间窗: Approximately 2 years postoperatively.
Negative values indicate hip compression, position values indicate hip separation. All "Diseased Hip" subjects were re-analyzed approximately 2 years postoperatively to yield the "Implanted Hip" group.
Magnitude of Hip Separation During Contra-lateral Toe Off
时间窗: Approximately 2 years postoperatively.
Negative values indicate hip compression, position values indicate hip separation. All "Diseased Hip" subjects were re-analyzed approximately 2 years postoperatively to yield the "Implanted Hip" group.
Magnitude of Hip Separation During Contra-lateral Heel Strike
时间窗: Approximately 2 years postoperatively.
Negative values indicate hip compression, position values indicate hip separation. All "Diseased Hip" subjects were re-analyzed approximately 2 years postoperatively to yield the "Implanted Hip" group.
