This questionnaire has been validated in different populations of patients. The present study aimed to determine the validation status of the Persian version of ZCQ.

Investigating the correlation between hip abductor muscle strength and width in anteroposterior pelvic radiographs in hip revision candidates following previous total hip arthroplasty: a cross-sectional study.

Unlabelled: The changes in strength of hip abductor muscles after total hip arthroplasty may depend on its anatomical parameters. In the present study the correlation between the strength of the hip abductor muscles before hip revision surgery and the diameter of the abductor muscles in the pelvic anterior posterior X-ray was investigated.

Methods: This cross-sectional study included the patients underwent hip arthroplasty and were candidates for revision surgery.

Direct posterior approach to posterior cruciate ligament bony avulsion fractures: a case series introducing a new surgical technique.

Failure to properly treat this injury causes instability in the knee. Although various surgical approaches have been introduced for this injury, there is controversy regarding selecting the suitable method under certain conditions.
