Abstract
Background:THA and TKA are conventional clinical procedures that offer a long-term solution for serious osteo and rheumatoid arthritis and severe joint deterioration, enhance mobility and overall abber qualitatively the quality of life of millions of patients around the world. However, this method and materials are not without their drawbacks namely implant wear and long hours of rehabilitation, thus the need to continually innovate.
Aim:This research will seek to identify newer implant materials, newer surgical approaches and post surgical rehabilitation techniques for THA and TKA and assess the effectiveness of the innovation.
Methods:The electronic databases of PUBMED, Cochrane, EMBASE, and Web of Science were searched for clinical trials, cohort studies, and meta-analysis of innovations that occurred in the recent decade. Studies were identified through PubMed as well as clinical trial databases, and orthopaedic journals and outcomes were analysed and compared to the following parameters: implant durability, precise positioning, incidence of complications, patient’s improvement, patient satisfaction, and the quality of life.
Results:Recent implant materials introduced in the market include cross-linked polyethylene, ceramics, and titanium alloys; they have overcome the problem of wear resistance and low revision rates. MIS and Robotic assisted surgery is a specialty, which replaces conventional and time tested open surgery provides high degree of accuracy improving recovery period. New postoperative rehabilitation treatments, such as early mobility and telehealth-based physiotherapy and occupational therapy, contribute to improved functional outcomes and valued by patients, decreases the length of stay and readmission rates.
Conclusion:The advancements in materials, in technique, and in postoperative care have raised the bar for joint replacement surgery making the process safer, longer lasting, and more cantered on the end user. Yet, cost and issues of access have remained a contentious issue for constant research in its practical application to be made cost effective and accessible. Such progressive changes show clear evidence of sustained enhancement of patient and service delivery outcomes.
