More information on hip relacement is as follows.

To prevent the joint dislocation or subluxation when the joint is unstable in the early postoperative days and weeks, the patient must avoid full ROM of operated hip.

If a posterolateral incision is made, excessive hip flexion and adduction beyond neutral must be avoided. During the first post operative days, avoid hip flexion past 45 degree and adduction past neutral during range of motion and ADLs. By two to three week postoperatively the patient is usually allowed to flex the hip to 90 degree. However, many surgeons agree to achieve the hip flexion up to 90 degree during the first two to three weeks.

If procedure involved an anterolateral approach, the patient should avoid hyperextension of hip as well as adduction past neutral.

Excessive hip Rotation must also be limited while tissue heals. If posterolateral approach is used, avoid internal rotation of hip. If anterolateral incision is used, avoid external rotation of hip.

Patients with cemented joint replacements can bear weight as tolerated unless the operative procedure involved a soft tissue repair or internal fixation of bone. Usually with cemented approach full weight bearing is started on the second post operative day while re-educating gait usually with walker or elbow crutches. However, with uncemented approach gait pattern is non weight bearing for 6 weeks, then partial weight bearing for 6 weeks. Walking aid must be used for 3 months.

Activities of daily living should be adapted as follows:

Have the patient transfer to the sound side.
Have the patient avoid sitting in low soft chair.
Suggest the patient to use raised toilet seat.
Do not allow the patient to excessively bend trunk over the operated hip when rising from a chair or to pick up an object from the floor.
Do not allow the patient to cross his legs.
Suggest to the patient that he or she sleep with an abduction pillow and to avoid sleeping on the side for atleast 8 to 12 weeks.
Do not turn your legs inwards.
An assistive such as walker, elbow crutch or stick is necessary to perform activities of daily livings.
Driving is not allowed for 6 weeks because there is loss of proprioceptive input to the hip joint.
