Hip offset parameters and functional outcomes following total hip arthroplasty: association with performance, strength, and patient-reported outcomes

While offset restoration did not relate to global functional tests such as TUG or WOMAC, patients with decreased global offset exhibited persistent abductor weakness, and contralateral offset parameters were associated with pain perception. These findings highlight the complexity of the relationship between offset and functional recovery and emphasize the importance of accurate offset restoration and bilateral biomechanical assessment in optimizing long-term outcomes following THA.
