Medial arthrosis of the knee is an evolutionary pathology that occurs due to progressive muscle imbalance. The muscles of the knee region have a large imbalance caused by the difference of power and lever arm. With the progression of life, this imbalance manifests itself more importantly, especially due to the loss of muscle strength due to aging. Pathological postures begin to occur and determine areas of support and pressure harmful to the joint. Meniscal injury is typical in the evolution of this pathology, as well as cartilage injury. The recognition of this pathology enables good results with less aggressive treatments, such as correction of muscle imbalance and consequent reeducation of joint support. Economic and partial meniscectomy brings good results in the early stages of the degenerative process. Progressive evolution leads to knee degeneration and the consequent need for broader surgeries.
膝关节内侧关节炎是一种因肌肉逐渐失衡而出现的渐进性病理状况。膝关节区域的肌肉存在由力量和力臂差异导致的巨大失衡。随着年龄增长，这种失衡愈发明显，尤其是由于肌肉力量丧失。病理性姿势开始出现，并确定对关节有害的支撑和压力区域。在这种病理状况的发展过程中，半月板损伤以及软骨损伤都很典型。认识到这种病理状况有助于通过不太激进的治疗取得良好效果，比如纠正肌肉失衡以及随后对关节支撑进行再训练。在退变过程的早期，经济性部分半月板切除术能带来良好效果。病情的逐渐发展会导致膝关节退变，进而需要更广泛的手术。
