Modular bicompartmental arthroplasty is an emerging knee-resurfacing approach that provides a conservative alternative to total knee arthroplasty. Isolated bicompartmental arthritis involving the medial or lateral and patellofemoral compartments, but with no significant deformity or bone deficiency, preserved motion, and intact cruciate ligaments, can be effectively managed with this treatment method. For the many young and active patients with isolated bicompartmental arthritis, given the potential durability of the procedure and the prosthesis, it is appropriate to use an approach that is more conservative than total knee arthroplasty. Robotic arm assistance for modular bicompartmental arthroplasty optimizes component position and alignment, which may improve system performance and long-term durability. In addition, a percentage of patients who undergo isolated unicompartmental or patellofemoral arthroplasty may later develop progressive arthritis in an unresurfaced compartment. Their cases may be effectively managed with a staged modular approach to resurfacing the degenerating compartment, but additional study is needed.
模块化双室关节成形术是一种新兴的膝关节表面置换方法，为全膝关节置换提供了一种保守的替代方案。对于仅累及内侧或外侧以及髌股关节间室、但无明显畸形或骨缺损、保留运动功能且交叉韧带完整的孤立性双室关节炎，可采用这种治疗方法有效处理。对于许多患有孤立性双室关节炎的年轻活跃患者，考虑到该手术及假体的潜在耐用性，采用比全膝关节置换更保守的方法是合适的。模块化双室关节成形术的机器人手臂辅助可优化假体组件的位置和对线，这可能会改善系统性能和长期耐用性。此外，一部分接受孤立性单室或髌股关节置换术的患者，后期可能会在未进行表面置换的关节间室出现进行性关节炎。他们的病例可通过分期模块化方法有效处理退变的关节间室，但仍需进一步研究。
