Conditions
Brief summary
This study will compare postoperative pain, health related quality of life (HRQoL), function, rehabilitation, urinary incontinence, muscle atrophy and component positioning in total hip arthroplasty (THA) using the posterolateral approach (PLA) or the direct superior approach (DSA). In addition, the CT images will be used to validate a new metal artefact reduction technique.
Detailed description
Objective: The primary objective is to evaluate health related quality of life (HRQoL) after THA using the DSA compared to the golden standard PLA in patients with incapacitating hip osteoarthritis after two weeks. The secondary objectives are divided into 1) long-term HRQoL evaluation, 2) physical performance, 3) radiologic muscle atrophy and component placement of the THA, 4) validation of a new metal artifact reduction technique for CT, and 5) relationship urinary incontinence and muscle atrophy. Study design: Multicenter, prospective, double blinded, randomized controlled intervention study in which the used operation method is not shared with the patient until one year after surgery and in which the study researcher is also blinded. Study population: A total of 211 men and women, age ≥ 18 years, with symptomatic hip osteoarthritis in whom THA is indicated. Intervention (if applicable): For this randomized controlled trial (RCT), patients will be randomly allocated in one of two groups: one group receives THA by using PLA, the other group receives THA by using DSA. Main study parameters/endpoints: As primary outcome specifically the Hip Disability and Osteoarthritis Outcome Score- Physical Function Short Form (HOOS-PS) is used for the short-term HRQoL. Secondary parameters/endpoints are split up into different categories. 1) HRQoL evaluation on the long term using patient reported outcome measures (PROMs) (NRS score, Short form-12 (SF-12), HOOS subscales, Global rating of change, and Euro Quality of Life questionnaire). 2) Physical function using physical functioning test (Timed Up and Go test, 40-meter self-paced walk test for hip osteoarthritis and Stair Climb Test). 3) Muscle atrophy measurements using CT scans. Muscle atrophy is expressed in both quantity of muscle volume loss and extend of fatty infiltration using the Goutallier scale. Component placement is measured in different angles. 4) Evaluation of a new metal artifact reduction technique for CT images. 5) Relationship between muscle atrophy and urinary incontinence after total hip replacement. Other study parameters include preoperative demographics such as age and gender, perioperative data such as blood loss, use of analgetics, operation time and postoperative complications such as infection, aseptic loosening and dislocation.

The scans will be reconstructed with a slice thickness of 0.9 of 1 mm and with an additional soft tissue filter. The pre-operative CT scans will be performed with a kilovoltage peak (kVp) of 120. The post-operative scans will be performed at 140 kVp, which helps to mitigate metal artifacts. In addition, the post-operative CT scans will be edited with metal artefact reduction for orthopedic implants (O-MAR; Philips Healthcare).

The angle of the neck of the prosthesis relative to the horizontal plane, angle a, is measured in the coronal slice containing the thickest diameter of the neck and is also measured with respect to the ischial bone.

The anterior opening angle of the cup (angle β) is measured on the axial slice at the middle of the head of the prosthesis in which posterior acetabulum is used as an internal reference. The angle of the neck of the prosthesis relative to the horizontal plane, angle a, is measured in the coronal slice containing the thickest diameter of the neck and is also measured with respect to the ischial bone.

| overall image quality | pre- operatively and 12 months postoperatively | Images will be edited by deep-learning metal artifact reduction technique (DL-MAR) and by O-MAR. The post-surgery images with and without O-MAR and the images with DL-MAR will be scored by four radiologists. During this assessment, the radiologist will also have access to the pre-surgery Computer Tomography (CT) scans. The images with and without O-MAR and with DL-MAR will be scored by the radiologists using a five-point scale. The images will be scored on: overall image quality. A five point scale with score 1-5 will be used, including very poor (1), poor (2), fair (3), good (4) and excellent (5). |

The post-surgery images with and without O-MAR and the images with DL-MAR will be scored by four radiologists. During this assessment, the radiologist will also have access to the pre-surgery Computer Tomography (CT) scans. The images with and without O-MAR and with DL-MAR will be scored by the radiologists using a five-point scale. The images will be scored on: 1) diagnostic confidence for bone, 2) diagnostic confidence for muscle, 3) diagnostic confidence for pelvic organs. a five point scale with score 1-5 will be used, including very poor (1), poor (2), fair (3), good (4) and excellent (5). |

The post-surgery images with and without O-MAR and the images with DL-MAR will be scored by four radiologists. During this assessment, the radiologist will also have access to the pre-surgery Computer Tomography (CT) scans. The images with and without O-MAR and with DL-MAR will be scored by the radiologists using a five-point scale. The images will be scored on: severity of metal artifacts. a five-point scale including severe (1), pronounced (2), moderate (3), mild (4) and none (5) will be used. |
| Incontinence Severity Index (ISI) | pre-operatively and 6 weeks and 12 months postoperatively | this index consists of two questions about the frequency and the quantity of urinary incontinence (92). The value of each question will be multiplied. A higher score means more severe urinary incontinence. |

A four-point Likert scale is used (1 = not at all - 4 = greatly.). A higher total score means a bigger impact. |
| Incontinence after Total Hip Arthroplasty | 6 weeks and 12 months postoperatively | this customized question concerns the opinion of the subject if urinary incontinence is changed after the total hip arthroplasty. This question will only be administered at six weeks and one year postoperatively.participation in daily life, social contacts and emotional status (93). A four-point Likert scale is used (1 = not at all - 4 = greatly.). A higher total score means a bigger impact. |
| Comparing definite cup position with preoperative planned cup position | pre- operatively and 12 months postoperatively | The initial abduction/inclination of the cup, angle α, is measured with respect to ischial bone, which is used as internal reference. The anterior opening angle of cup (angle β) is measured on axial slice at the middle of the head of the prosthesis in which the posterior acetabulum is used as internal reference. The angle of the neck of the prosthesis relative to the horizontal plane, angle a, is measured in coronal slice containing the thickest diameter of the neck and is measured with respect to ischial bone. The anteversion angle of the neck around the vertical axis, angle b, is measured in the axial slice Pre-operative hip component planning will be conducted using X-ray and CT images. Regarding component planning, the use of X-ray is sufficient. 3D planning using CT images will be performed retrospectively. Cup position will be compared between the 2D and 3D planning and with the definite positions |
