Application of the Endomodel rotating hinge knee prosthesis for knee osteoarthritis.
One hundred thirty-six knees were treated with the Endomodel rotating hinge knee prosthesis as primary total knee arthroplasty (TKA). The indications for surgery included osteoarthritis (110 knees), rheumatoid arthritis (18 knees), and osteonecrosis (8 knees). Patients were divided into four study groups according to follow-up duration. Group A was followed up from 10 to 15 years, group B from 8 to 10 years, group C from 5 to 8 years, and group D from 2 to 5 years. The Hospital for Special Surgery knee score, as well as each parameter individually, showed statistically significant improvement in all groups postoperatively. A total of 88.23% were rated as excellent, 3.67% as good, and 8.08% as fair. The results suggest that the Endomodel rotating hinge prosthesis can be considered a good alternative for primary TKA in cases of serious axial deformity and collateral ligament deficiency and in rheumatoid arthritis patients.
