Background:
The occurrence of chronic knee dislocation is rare. To the best of our knowledge, total knee arthroplasty for treatment of chronic anterior knee dislocation has not been reported.
Method:
This report describes 3 cases of chronic anterior knee dislocation treated by total knee arthroplasty.
Results:
Three female patients with chronic anterior knee dislocation were treated by hinged prosthesis total knee arthroplasty using the Insall rectus snip approach. At a mean of 17 months (range, 12-24 months) of follow-up, all patients showed a painless stable prosthesis and expressed satisfaction with the results.
Conclusions:
Total knee arthroplasty for chronic anterior knee dislocation is a challenging procedure. The Insall rectus snip approach with quadriceps release and constrained prosthesis is recommended.
