Neglected rotatory knee dislocation: A case report

•We report a unique case of neglected rotatory tibiofemoral dislocation.•Lateral patella dislocation exists in this case.•Taylor spatial frame was used for correction of the tibiofemoral dislocation.•Tibial tubercle osteotomy and transfer was done for optimal patellar alignment.•Multi-disciplinary approach was used in this case for optimal outcome.

We report here a unique case of a 3 year neglected rotatory tibiofemoral dislocation associated with a lateral patellar dislocation. The rotational deformity was gradually corrected using a Taylor spatial frame and the patella was realigned by tibial tubercle osteotomy and transfer. The patient also underwent multiple soft tissue releases and quadricepsplasty to improve knee flexion. At nine year follow-up, the patient has good knee range of motion, a congruent knee joint and a good functional result.Clinical relevance: Taylor spatial frame combined with other orthopedic approaches can be a useful tool while dealing with neglected knee dislocations.
