Advantages and limitations

Advantages

•Reasonable alternative for a young, active patient who wishes to avoid a revision arthroplasty procedure

•Restoration of valgus stability may help to reduce implant wear and need for accelerated revision

•The residual allograft remaining can be folded on top of itself to produce a double-stranded reconstruction of the posterior oblique ligament (POL) and ultimately reinforce the posterior capsule

Limitations

•Limited data on longevity of reconstruction in the setting of beforetal knee arthroplasty

•Arthroplasty surgeons typically have less experience managing this patient presentation in the setting of additional POL injury

•Revision arthroplasty procedure may be needed in future due to accelerated polyethylene wear, especially in chronic situations
