Abstract:
Objective To introduce the application scene,operating steps and preliminary clinical effect of tibial bone mass preservation technique in medial unicompartmental knee arthroplasty(MUKA).Methods A total of 15 patients with antero-medial knee osteoarthritis(AMOA)treated in this hospital from May 2022 to May 2023 were selected as the study subjects.The tibial bone mass preservation technique was a-dopted to complete MUKA(fixed platform prosthesis).The operating time,intraoperative bleeding volume,hospitalization duration and operation complications were recorded.The VAS score before operation and in last follow up,range of motion(ROM)of knee joint,Knee Society Score(KSS),hip and knee stomping angle(HKA)of lower extremity in the operation side and image results were recorded to evaluate the clinical effect.Results The operations in 15 cases were successfully completed.The average operation time was(82.73±9.97)min,mean intraoperative bleeding volume was(21.00±9.49)mL and average hospital stay was(4.9±1.4)d.There was no intraoperative nerve,vascular and medial collateral ligament injury,no iatro-genic fracture,and no postoperative surgical site infection.All patients were followed up for average(5.87±2.77)months.The VAS score of knee joint,ROM,KSS and HKA angle of lower limb in the operated side were significantly improved compared with before operation(P<0.05).There was no prosthesis loosening,displacement or fragmentation,and no obvious degeneration aggravation of the lateral compartment of the knee joint.Conclusion The tibial bone mass preservation technique is a simple,effective and reliable method to deal with the slightly tight flexion space after tibial osteotomy during MUKA,and the postoperative clinical efficacy and imaging results are excellent.
