The well-cemented total hip arthroplasty (THA) theory and practice refer to a surgical technique where prosthetic components of the hip joint are securely fixed in place using bone cement, specifically polymethylmethacrylate (PMMA). This approach is primarily indicated for patients with osteoarthritis, rheumatoid arthritis, or hip fractures, particularly in older individuals with less demanding physical activity levels. The theory emphasizes that the effective use of cement creates a stable interface between the bone and the implant, enhancing initial fixation and promoting long-term durability. Practically, the procedure involves meticulous preparation of the femur and acetabulum, ensuring optimal cement application to fill any voids and provide a robust bond. Surgeons must pay attention to factors such as cement viscosity, temperature, and polymerization time, as these influence the strength of the bond. Over the years, advances in cementing techniques, including improved instrumentation and the use of modern cements, have contributed to reduced complications and improved outcomes. Postoperative rehabilitation plays a critical role in the success of well-cemented THA, focusing on restoring mobility and strength while minimizing complications such as dislocation or infection. Long-term studies have shown that well-cemented implants can provide excellent survivorship rates, making them a reliable choice in hip arthroplasty. However, ongoing research continues to explore the long-term effects and durability of cemented versus cementless implants, guiding future practices in orthopedic surgery. In summary, the well-cemented total hip arthroplasty theory and practice represent a cornerstone of hip replacement techniques, blending surgical skill with scientific understanding to optimize patient outcomes.
