Abstract：
OBJECTIVE: To compare clinical outcomes of high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) for anterior medial osteoarthritis (AMOA) as well as offer surgical recommendations through age stratification.
METHODS: Between May 2019 and May 2021, 68 cross-indicated AMOA patients were analyzed. The patients were divided into HTO and UKA groups and further into two age groups of 55-60 and 60-65 years. Additionally, general data, visual analog scale (VAS) score, and Hospital for Special Surgery knee score (HSS) were analyzed.
RESULTS: All the patients were followed up for 18 months. Knee joint HSS significantly improved, and VAS score decreased in both groups (P < 0.05). In the 55-60 age group, HTO showed superior knee HSS at 1 and 3 months (P < 0.05), with no significant difference at 6, 12, and 18 months. HTO had a significantly lower VAS score at one month, and the VAS scores of the two groups decreased gradually with no significant difference. In the 60-65 age group, the UKA group showed superior knee joint HSS at one month, with no significant difference at 3, 6, 12, and 18 months. The UKA group had a significantly lower VAS score at one month, and both groups\' VAS scores decreased gradually with no significant difference.
CONCLUSIONS: Both methods yield satisfactory results for AMOA cross-indications, improving knee joint function. The observed recovery trends have implications for personalized surgical recommendations, guiding interventions based on age-specific considerations for optimal outcomes in anterior medial osteoarthritis cases.

摘要：
目的：比较胫骨高位截骨术（HTO）和单室膝关节置换术（UKA）治疗前内侧骨关节炎（AMOA）的临床效果，并通过年龄分层提供手术建议。
方法：在2019年5月至2021年5月之间，对68例交叉指征AMOA患者进行了分析。将患者分为HTO组和UKA组，并进一步分为55-60岁和60-65岁的两个年龄组。此外,一般数据，视觉模拟量表（VAS）评分，并对特殊外科医院膝关节评分(HSS)进行分析。
结果：所有患者均获随访18个月。膝关节HSS明显改善，两组VAS评分均降低(P<0.05)。在55-60岁年龄段，HTO在1个月和3个月时显示膝关节上HSS（P<0.05）。在6、12和18个月时无显著差异。HTO在一个月时的VAS评分明显较低，两组患者的VAS评分逐渐降低,差异无统计学意义。在60-65岁年龄段，UKA组在1个月时表现为上膝关节HSS，在3、6、12和18个月时无显著差异。UKA组在1个月时的VAS评分明显较低,两组VAS评分均逐渐下降，差异无统计学意义。
结论：两种方法都对AMOA交叉适应症产生了令人满意的结果，改善膝关节功能。观察到的恢复趋势对个性化手术建议有影响，指导基于年龄特定考虑因素的干预措施，以实现前内侧骨关节炎病例的最佳结局。
