Objective To summarize the effectiveness of bone cement combined with screws for repairing tibial plateau defect in total knee arthroplasty (TKA). Methods Between March 2013 and March 2016, 30 patients were treated with TKA and bone cement combined with screws for repairing tibial plateau defect. Of the 30 patients, 8 were male and 22 were female, with an average age of 64.7 years (range, 55-71 years). And 17 cases were involved in left knees and 13 cases in right knees; 22 cases were osteoarthritis and 8 cases were rheumatoid arthritis. The disease duration ranged from 9 to 27 months (mean, 14 months). Knee Society Score (KSS) was 41.63±6.76. Hospital for Special Surgery Knee Score (HSS) was 38.10±7.00. The varus deformity of knee were involved in 19 cases and valgus deformity in 11 cases. According to the Rand classification criteria, tibial plateau defect were rated as type Ⅱb. Results All incisions healed by first intention, without infection or deep vein thrombosis. All the patients were followed up 27.5 months on average (range, 10-42 months). At last follow-up, HSS score was 90.70±4.18 and KSS score was 93.20±3.75, showing significant differences when compared with preoperative values (t=–58.014, P=0.000; t=–60.629, P=0.000). Conclusion It is a simple and safe method to repair tibial plateau defect complicated with varus and valgus deformities with bone cement and srews in TKA.
