올바른 표현

• 医生检查后说，这位长期重体力劳动者的膝盖半月板已明显磨损，若不及时保守治疗，可能要手术。(After the examination, the doctor said that this long-time heavy laborer’s knee meniscus was already badly worn, and if conservative treatment was not started in time, surgery might be needed.)
• 研究表明，跑步时前脚掌着地比脚跟着地更能减轻膝盖冲击，所以教练常建议系统矫正跑姿。(Studies show that landing on the forefoot while running reduces impact on the knees better than heel striking, so coaches often recommend systematic gait correction.)

피해야 할 표현

• 膝盖 in very formal medical writing where 膝关节 (knee joint) is the precise anatomical term — while 膝盖 is universally understood, formal clinical reports and anatomical descriptions typically use 膝关节 to refer specifically to the joint structure
