| description | Background
Osteoarthritis (OA) of the knee with varus deformity is a common degenerative condition that severely impacts mobility and quality of life. Total Knee Arthroplasty (TKA) is the standard surgical treatment for end-stage OA, though varus correction poses technical challenges.
Objectives
To evaluate the clinical, functional, and radiological outcomes of TKA using a posterior cruciate substituting prosthesis in patients with varus knee deformity.
Methods
This prospective observational study included 30 patients (mean age: 63.2 years; 70% female) with primary OA and varus deformity (Kellgren–Lawrence grades III and IV), who underwent TKA at Mahatma Gandhi Memorial Hospital, Warangal. Clinical and functional status were assessed using the Knee Society Score (KSS), while radiological evaluation confirmed prosthetic alignment. Follow-ups were performed at 6 weeks, 3 months, 6 months, and 1 year.
Results
The mean preoperative clinical KSS (56.4) improved significantly to 90.2 postoperatively (p < 0.01), and the functional score improved from 48.3 to 81.6 (p < 0.01). Radiographs showed that all patients achieved neutral mechanical alignment without signs of implant loosening. By 6 weeks, over 80% of patients reported substantial pain relief, restored range of motion, and improved stair-climbing ability. No intraoperative or postoperative complications, such as infection or DVT, were reported. Outcomes were favorable across all deformity severity groups (<10°, 10–20°, >20°).
Conclusion
TKA using posterior cruciate substituting prostheses provides significant functional and radiological improvements in osteoarthritic knees with varus deformity. Proper preoperative planning and surgical precision are key to optimal outcomes.
Recommendations
Preoperative assessment should emphasize deformity severity and soft tissue balance. Surgeons should adopt individualized soft tissue release techniques and confirm mechanical axis restoration intraoperatively. Long-term follow-up and larger sample studies are recommended to assess prosthesis survivorship and late complications. |
