Introduction.High tibial osteotomy (HTO) is a frequent and effective treatment for unicompartmental gonarthritis.Only a few articles are focused on the treatment Patio Seating Package of infected nonunion.

Patient and Method.A 50-year-old obese patient was operated on by medial opening-wedge HTO.She developed a painful nonunion treated by hardware removal, allograft, and plate fixation.

However, the nonunion persisted.2 years later, cellulitis appeared with an abscess adjacent to the HTO plate.Despite surgical debridement and antibiotics, septic knee arthritis occurred.

In a situation of infected nonunion and septic arthritis with chondrolysis, she was scheduled for a 2-stage total knee replacement (TKR).The infected tibial articular block was first resected and replaced by a cement spacer.After a short interval, the TKR was implanted.

After 2 years, the patient walked pain-free with good knee function.Discussion.In the literature, different efficient treatments exist for infected nonunion after HTO, but comprehensive studies are missing for a consensus treatment.

Current data are mostly based on case reports, since this pathology is quite rare.Conclusion.In a difficult situation of infected nonunion with septic knee arthritis, we performed a 2-stage knee Apparel prosthesis implantation.

This led to an early mobilization and fast recovery.
