“…Elsayed et al and Passarelli et al 21,22 reported a significant increase in the KSS in both the BG and NF group compared with the preoperative score; however, no significant difference was observed in the BG or NF group, which suggests that bone grafting does not affect the postoperative function of the knee joint following OWHTO. In addition, Zorzi et al's study 18 showed no statistically significant difference in the meantime to clinical bone union between the BG ( 15,16 also showed no difference in time to clinical or radiologic union between the groups.…”

“…In the NF group, one knee exhibited screw penetration in the posterolateral portion of the knee joint and the other two knees exhibited local irritation that required the removal of the implanted hardware. In Elsayed et al's study, 21 five patients (two in the BG group and three in the NF group) exited bone resorption around the metal; five patients (three in the BG group and two in the NF group) had superficial infections; ten patients (six in the BG group and four in the NF group) developed hematomata; and four patients (three in the BG group and one in the NF group) developed deep venous thrombi. In Zorzi et al's study, 18 the most frequent complication was hematoma, which occurred in two patients in the BG group (8.7%) and in four patients in the NF group (17.4%).…”

“…16,19,21 The lateral tibial cortex was fractured in four cases of Zorzi et al's study, 19 and two of those presented delayed clinical bone union and loss of correction, suggesting that lateral cortical breach may increase the loss of correction and result in delayed clinical bone union. In addition, Elsayed et al's study 21 used correlation analysis to investigate the relationship between the correction rate and pre-and postoperative difference in the posterior tibial slope and found that increased posterior tibial slope would result in a loss of correction in the frontal plane following medial OWHTO. In Alolabi et al's study, 3 and 8% of patients in the AU and AL groups developed nonunion (p ¼ 0.64), 17 but no patient developed nonunion in Cho et al' study.…”

Bone grafting is a good alternative for filling the inevitable void that is created following opening-wedge high tibial osteotomy (OWHTO). This systematic review and meta-analysis evaluated whether bone grafting is necessary for OWHTO and the successful outcomes of OWHTO using either autograft (AU) or allograft (AL). All analyzed studies were acquired from PubMed, Medline, Embase, CNKI, Google Scholar, and Cochrane Library. Data were independently extracted by two coauthors and were analyzed using RevMan5.3. Mean differences, odds ratios, and 95% confidence intervals were calculated. Cochrane Collaboration's Risk of Bias Tool and Newcastle–Ottawa Scale were used to assess the risk of bias. In total, 10 studies were assessed including three randomized controlled trials and seven observational studies. The methodological quality of the trials ranged from low to high. The overall estimate demonstrated that the difference between OWHTO using AU and AL groups and OWHTO using no filling group was not statistically significant for the loss of correction, and complications, but OWHTO using no filling group statistically showed better knee society score. Pooled results of reoperations, lateral cortex breaches, complications, and clinical function assessments showed no significant difference between AU and AL materials. Using AL statistically reduced the operative time compared with using AU. OWHTO with or without bone graft does not affect postoperative complications. No loss of correction was observed due to the lack of bone grafting. In addition, OWHTO without bone graft performs better for postoperative clinical function assessment. Complications and clinical results of medial OWHTO were similar using AL and AU and neither reported a median loss of correction of following OWHTO. Compared with using AU, using AL avoids harvest site complications and reduces operative time. To sum up, OWHTO without any bone graft is recommended for medial unicompartmental osteoarthritis of the knee. Further large-sample, multicenter, high-quality, randomized controlled trials are warranted to verify the outcomes of this meta-analysis.
