[Chinese expert consensus on clinical practice of daytime hip arthroplasty].

Daytime hip arthroplasty refers to a medical procedure where a patient undergoes admission, surgery, and discharge all within a single day (24 hours). The establishment of daytime hip arthroplasty centers signifies a significant paradigm shift in the development model of modern hospitals. While numerous nationally accredited large medical institutions are undertaking daytime hip arthroplasty in various forms and scales, there remains a lack of standardized system processes and criteria. In this context, the National Clinical Research Center for Geriatric Disorders (Xiangya Hospital), Bone and Joint Specialty Committee of the China Ambulatory Surgery Alliance, Joint Surgery Branch of the Chinese Orthopedic Association, and Osteoarthritis Study Group of the Chinese Association of Orthopedic Surgeons have collaboratively organized experts in the relevant field domestically. Leveraging international experiences in daytime hip arthroplasty and integrating them with the clinical practices of well-established medical institutions conducting daytime surgeries in China, they have arrived at consensus recommendations. These recommendations cover the establishment of daytime hip arthroplasty centers, policies, procedures, and perioperative management. The ultimate goal is to provide reference points and guidance for the standardized implementation of daytime hip arthroplasty.

[Expert consensus on surgical treatment of patellofemoral osteoarthritis].

Patellofemoral osteoarthritis (PFOA) is one of the most common causes of anterior knee pain in middle-aged and elderly population. In general, elementary therapy and drug therapy are the preferred choices for PFOA management. However, for those who cannot achieve satisfactory effectiveness with standard non-surgical treatment, surgical therapy stands as an alternative treatment. The surgical therapy includes repair surgery and reconstruction surgery. The choice of surgical plans for PFOA management mainly depends on the etiology, pathogenesis, location, and severity of the lesions. To aid clinical decision-making, the National Clinical Research Center for Geriatric Disorders (Xiangya Hospital) and the Joint Surgery Branch of the Chinese Orthopedic Association arranged nationwide orthopedic specialists to set up a work panel. After reviewing the research progress of surgical therapy and the latest guidelines and consensus for PFOA management, the work panel discussed repeatedly to reach this consensus. The present consensus aims to provide valid evidences for clinical practices of the surgical therapy of PFOA, so as to avoid inappropriate and irregular treatment behaviors, reduce surgical trauma, improve surgical efficacy and the quality of life, and to ease the burden of PFOA.
