Abstract
Background: This study was aimed at comparing the efficacy and safety of bicompartmental knee arthroplasty (BKA) and total knee arthroplasty (TKA) in treating bicompartmental knee osteoarthritis through a systematic evaluation and meta-analysis.
Methods: A comprehensive systematic literature search of the Pub Med, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov databases was performed to identify the relevant scientific literature published until 1st March 2024. The eligible studies were evaluated for quality assessment and data extraction, and meta-analysis was performed using Review Manager 4.1 software.
Results: A total of 1378 studies were identified. Based on strict inclusion criteria, 12 studies were finally included in this meta-analysis. The results of the analysis revealed that BKA yielded better postoperative outcomes than TKA, in terms of Knee Society Score (KSS) Knee Score, Function Score, and range of knee flexion (P = 0.02; P < 0.0001; P = 0.0005, respectively). Intraoperative bleeding in the BKA group was significantly lower than that in the TKA group (P = 0.02), although postoperative complications (P < 0.05) were higher and operative time (P = 0.04) was longer in the BKA group. However, the two groups did not show any significant difference in terms of Oxford knee score and WOMAC pain score (P = 0.53 and P = 0.96, respectively).
Discussion: Our present results indicate that while BKA affords better improvement in knee function and quality of life in bicompartmental knee osteoarthritis than TKA, it also increases complications and operative time. Therefore, further studies are warranted to confirm these results and assess long-term outcomes and cost-effectiveness.
期刊介绍：
Journal of Orthopaedic Surgery and Research is an open access journal that encompasses all aspects of clinical and basic research studies related to musculoskeletal issues.
Orthopaedic research is conducted at clinical and basic science levels. With the advancement of new technologies and the increasing expectation and demand from doctors and patients, we are witnessing an enormous growth in clinical orthopaedic research, particularly in the fields of traumatology, spinal surgery, joint replacement, sports medicine, musculoskeletal tumour management, hand microsurgery, foot and ankle surgery, paediatric orthopaedic, and orthopaedic rehabilitation. The involvement of basic science ranges from molecular, cellular, structural and functional perspectives to tissue engineering, gait analysis, automation and robotic surgery. Implant and biomaterial designs are new disciplines that complement clinical applications.
JOSR encourages the publication of multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines, which will be the trend in the coming decades.
