Put your right hip in, put your right hip out

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Hip replacement is a common procedure in the US, often necessitated by arthritis-related pain and joint degeneration.
• Current artificial hip joints have a lifespan of 10-20 years, potentially requiring revision surgery.
• Infection, though rare (<1%), can lead to severe complications and multiple surgeries.

Purpose of the Study:

• To provide an overview of current hip replacement procedures and emerging trends.
• To discuss various surgical techniques and their implications for patient recovery and outcomes.
• To highlight developing issues concerning hip replacement devices.

Main Methods:

• Review of current hip replacement surgical techniques, including conventional, minimally invasive surgery (MIS), MIS anterior-hip arthroplasty, and hip resurfacing.
• Discussion of fixation methods (cement, cementless, hybrid).
• Consideration of computer-assisted surgery and emerging device-related concerns.

Main Results:

• Minimally invasive surgery (MIS) reduces soft-tissue dissection compared to conventional methods.
• MIS anterior-hip arthroplasty is associated with shorter recovery times.
• Hip resurfacing offers an alternative, potentially better suited for younger, active patients.

Conclusions:

• Multiple surgical options exist for hip replacement, catering to different patient needs and potentially improving outcomes.
• Advancements like MIS and computer-assisted surgery aim to enhance precision and recovery.
• Ongoing considerations include device longevity, infection management, and device safety through registries and recall monitoring.
