It is established that patients and surgeons share different perceptions regarding total knee replacement (TKA). This study's objective was to determine patient perceptions regarding TKA as well as the influence of the various information sources in shaping these perceptions. All patients presenting with knee pain for evaluation of TKA were offered a questionnaire. Multivariate statistical analysis correlated response and demographic variables. Approximately 81% of patients felt the main reason for TKA was to alleviate pain, whereas only 19% felt return to sports-related activities was the main reason. Approximately 37% of patients felt TKAs should last for 20 years or more, which was strongly correlated with TV, newspaper, or Internet exposure (p ≤ 0.01). Approximately 38% of respondents had heard of partial knee replacement, whereas relatively few had received information regarding patient-specific, gender-specific, mobile-bearing, or high-flexion TKA designs. Men were likelier than women to get their information from friends, family, or another patient (p = 0.04). Although most respondents perceived pain relief as the primary goal, patients getting information from the media are likelier to expect TKA to last longer than 20 years. This suggests direct-to-patient marketing with such claims as 30-year durability may influence patient perceptions regarding TKA.
已证实患者和外科医生对全膝关节置换术（TKA）有着不同的认知。本研究的目的是确定患者对TKA的认知以及各种信息来源在形成这些认知方面的影响。所有因膝关节疼痛前来评估TKA的患者都被提供了一份问卷。多变量统计分析将回答与人口统计学变量相关联。约81%的患者认为TKA的主要原因是缓解疼痛，而只有19%的患者认为恢复与运动相关的活动是主要原因。约37%的患者认为TKA应该持续20年或更长时间，这与电视、报纸或网络曝光密切相关（p≤0.01）。约38%的受访者听说过部分膝关节置换术，而相对较少的人收到过关于患者特定、性别特定、活动平台或高屈曲TKA设计的信息。男性比女性更有可能从朋友、家人或其他患者那里获取信息（p = 0.04）。尽管大多数受访者将疼痛缓解视为主要目标，但从媒体获取信息的患者更有可能期望TKA持续超过20年。这表明以30年耐用性等说法进行直接面向患者的营销可能会影响患者对TKA的认知。
