Unicompartmental knee arthroplasty is a logical procedure when the lesion is limited to one femorotibial compartment. The procedure can now be performed through a mini-incision to provide quicker recovery because the extensor mechanism disruption is minimized. We have found the length of the incision varies according to patient mass and muscle tone. Specific instrumentation limited to the replaced compartment and using either an intra- or extramedullary femoral technique provides femorotibial component alignment and allows slight undercorrection of the deformity. Radiographic assessment demonstrates precise implantation of the components is possible with a mini-incision, which is believed important for the long-term results of the arthroplasty. The functional evaluation of patients implanted with unicompartmental knee arthroplasty performed through a mini-incision suggests appropriate kinematics can be restored after the procedure, enhancing the importance of a functional anterior cruciate ligament.

当病变局限于一个股胫关节间室时，单髁膝关节置换术是一种合理的手术方式。由于伸肌机制破坏最小化，现在该手术可通过小切口进行，以实现更快的恢复。我们发现切口长度会因患者体重和肌肉张力而有所不同。仅限于置换间室的特定器械，并采用髓内或髓外股骨技术，可实现股胫关节组件的对线，并允许对畸形进行轻微的欠矫正。影像学评估表明，通过小切口有可能精确植入组件，这被认为对关节置换术的长期效果很重要。对通过小切口进行单髁膝关节置换术的患者进行的功能评估表明，术后可恢复适当的运动学，这增强了功能性前交叉韧带的重要性。
