In a hip replacement, which type allows for faster exercise and weight bearing?

In the context of hip replacement procedures, cemented hip implants are designed to provide immediate stability and fixation to the bone by using a polymer-based cement. This allows for quicker rehabilitation and earlier weight bearing compared to non-cemented options. Patients with cemented implants typically experience a more secure attachment to the bone right after surgery, which facilitates faster recovery times and enables them to start exercises and weight-bearing activities sooner.

Non-cemented implants, while promoting biological fixation through bone growth over time, generally require a longer period before the patient can safely bear weight, as it takes time for bone to grow into the implant. Hybrid systems use a combination of cemented and non-cemented parts, which can vary in terms of recovery speed and weight-bearing protocols. Modified is not a standard category in hip replacement terminology; thus, it would not be relevant.

Cemented implants are therefore preferred for patients who may need a quicker return to function, such as those with higher activity demands or those ensuring a shorter recovery time post-surgery.
