The proposed advantages of HRA compared to conventional total hip arthroplasty (THA) include improved range of motion and hip function, bone preservation, lower dislocation rates, and easier and safer revision procedures in case of failure (Shimmin et al. 2008).
Theoretical benefits compared to conventional total hip arthroplasty (THA) include bone stock preservation, particularly on the femoral side, improved stability due to the large diameter bearing, improved range of motion and proprioception and technically less difficult revision to a total hip arthroplasty if necessary.
Large size hip articulations may improve range of motion (ROM) and function compared to a 28 mm THA, and the low risk of dislocation allows the patients more activity postoperatively.
Furthermore, the significant correlation found between postoperative PT improvement and clinical outcome appears to indicate that resetting PT to a normal value is important for restoring ambulatory function by improving the range of hip extension.
Improving IR may improve hip range of motion (ROM) or prevent hip pathology.
This systematic review finds that it is not yet possible to establish the extent to which post discharge physiotherapy exercise is effective, in terms of improving function, quality of life, mobility, range of hip joint motion and muscle strength, for osteoarthritic patients following elective primary unilateral total hip arthroplasty.
After treatment, no patient had ankylosis of the hip joint, all patients were able to sit, and the mean range of hip motion significantly improved (p = 0.001); the mean hip flexion after treatment was 79° (range, 30 100°), extension 17° (range, 10 30°), internal rotation 25° (range, 5 35°), external rotation 23° (range, 5 30°), abduction 25° (range, 5 40°), and adduction 17° (range, 5 25°).
Femoral shaft rotational osteotomy restores the functional range of hip motion, while correcting obligate out-toeing and improving knee kinematics.
This study evaluates whether hip bracing in patients with femoroacetabular impingement (FAI) (a) immediately reduces range of hip internal rotation, flexion, adduction, and pain during functional tasks; and (b) improves patient-reported outcomes when worn daily over 4 weeks.
