Introduction: The purpose of this paper is to present a possible treatment in case of inveterated knee dislocation which presented in out Institution as a subtle case after a common knee sprain.

The Case: A 74-year-old female patient with acute knee pain presented to our Institution in the Emergency Room, after a knee sprain occurred 48 hours before. Clinical assessment reported a knee swelling and limitation of the range of motion; no neurovascular complications were found. Knee X-ray was normal except for a lamellar bone detachment on medial condyle. The patient was treated conservatively with knee brace ad no weight-bearing; an MRI and clinical examination were prescribed after 3 weeks. Unfortunately the patient was not compliant and ignored medical prescription: she came back to outpatient clinic after 96 days without MRI with valgus knee and limping. An X-ray was executed and we observed a knee dislocation with disruption of both cruciate land collateral ligaments. In consideration of knee instability and the age of the patient we decided to treat this patient with a rotating hinge knee arthroplasty

Results Patient came back home after 6 days after surgery with good range of motion and good control of pain. After 40 days knee R.O.M. was 0°-90° and a good muscle trophism was observed.

Conclusions: Knee dislocation is a relatively rare but also a potentially serious injury for the patient. A diagnostic classification is essential for accurate diagnosis and treatment, which often requires multidisciplinary approach.

Level of evidence: Level IV case study
