Addressing the Challenges of Orthopaedic Bone Cement Removal

Advances in Major Joint Replacements

Hip, knee, and shoulder implants have positively impacted millions worldwide, reshaping lives and restoring mobility. With these surgeries becoming increasingly common among individuals over the age of 50 the annual occurrence of these procedures is projected to exceed 5 million by 2030¹.

However, challenges persist. Approximately 7% of hip, knee, and shoulder implants necessitate replacement due to issues like implant failure, infection, loosening, or bone fractures². For certain individuals, this could mean undergoing the complex and often painful process of revision surgery up to three times within their lifetime³. Notably intricate, these procedures are challenging on both patients and healthcare providers⁴.

Implant Fixation: Unveiling the Approaches

The process of implant fixation within major joints around two primary techniques: Uncemented and Cemented. Uncemented fixation involves securely anchoring the implant into the bone, allowing natural bone integration, while Cemented fixation utilises bone cement, a resilient compound comprising Polymethyl Methacrylate (PMMA)—to establish implant fixation and stability. However, the formidable challenge lies in the durability of bone cement, which proves difficult to remove and poses intricate surgical hurdles.

Rising Demand for Orthopaedics Revision Surgery

As the global population ages, the prevalence of joint replacements is growing. By 2030 the population of 60+ years is estimated to reach 1.4 billion⁵. This demographic stands as the largest beneficiaries of major joint implants, leading active, independent lives.

The pressing need to replace current orthopaedic implants presents a multidimensional challenge. These intricate surgeries impact not only the patients’ quality of life and mobility but also place strain on healthcare resources, extending to overburdened systems and providers. The surge in demand for revision surgery exacerbates issues such as prolonged waiting times for elective surgeries, decreased operating theatre availability, high surgical costs, suboptimal patient outcomes, heightened blood transfusion requirements during surgery, delayed rehabilitation, sluggish recovery, and increased procedure expenses.
