The aims of this study were to investigate the extent of early postoperative change in standing hip rotation angle (HRAng) in patients with osteoarthritis (OA) undergoing THA and to consider a possible mechanism behind this.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Materials and Methods:<\/jats:title>\n            <jats:p>A total of 82 hips (82 patients; 63 women and 19 men) undergoing unilateral primary THA with total capsulectomy were included. We characterized the standing HRAng and internal\/external range of motion (ROM) in the prone position before THA and 2 weeks after THA. Acetabular\/cup and femoral\/stem anteversion, combined anteversion (CA), and leg length discrepancy were also characterized. Correlations were examined postoperatively between the HRAng and the other analyzed variables.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              The median standing HRAng showed a significant internal shift from external to more medial position (6.3\u00b0 to 1.7\u00b0) 2 weeks after THA (\n              <jats:italic>P<\/jats:italic>\n              &lt;.0001). The postoperative change in standing HRAng was significantly negatively correlated with the difference between the postoperative femoral anteversion and the stem anteversion (\n              <jats:italic>r<\/jats:italic>\n              <jats:sub>s<\/jats:sub>\n              =\u22120.429,\n              <jats:italic>P<\/jats:italic>\n              &lt;.0001) and with the pre- to postoperative change in CA (\n              <jats:italic>r<\/jats:italic>\n              <jats:sub>s<\/jats:sub>\n              =\u22120.3012,\n              <jats:italic>P<\/jats:italic>\n              =.0063).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion:<\/jats:title>\n            <jats:p>\n              This study demonstrated that the extent of the rotational shift of the distal femur toward medial direction was significantly associated with increasing stem anteversion and CA. This phenomenon can be interpreted as a compensatory mechanism for maintaining the relative positional relationship between the pelvis and the proximal femur using proprioception. Therefore, we conclude that the extracapsular\/extra-articular components may be prominent determinants of joint position sense.
