We present a case of chronic anterior dislocation of knee in a 65-year-old female. She was suffering from type 1 neurofibromatosis and was having an intra-articular ganglion cyst of size 7 cm × 4 cm in between the patella and anterior aspect of the lower end of femur. We performed semi-constrained knee arthroplasty after excising the intra-articular ganglion cyst with satisfactory results. Postoperatively, the patient became ambulant with painless stable knee.
