Abstract

Background: In orthopaedic surgery, long-term outcome and prognosis are very crucial. Surgical methods to the knee joint and its surrounding structures vary, but they are all designed to provide the best access to a pathological area while protecting vital surrounding tissues. A perfectly aligned knee is required for installing a rotating platform device, which MPA can easily create. The subvastus method, on the other hand, allows for a perfect lateral exposure and a completely positioned knee.
Currently, the medial patellar approach is favoured for Total Knee Replacement, however our theory suggests that the lateral corner can be better viewed with the subvastus approach, making it a superior option for Rotating Platform Device insertion in varus, valgus, and stiff knee situations.
Aim: To determine the outcome of subvastus approach in all types of knee pathologies using mobile bearing rotating platform implant design.
Materials and Methods: We conducted prospective analysis of patients with limited preoperative ROM (flexion ?90°) of the knee who underwent TKA using subvastus approach and presenting the 6 months results. There were a total 60 patients (60 knees) with mean age 63 (range 49–79 years) years. The mean preoperative flexion was 44°.
Results: Postoperatively knee flexion improved by mean 95° (P < 0> Conclusions: Our findings show that employing the subvastus method, gratifying TKA results can be achieved in varus, valgus, and stiff knee cases with restricted preoperative ROM while maintaining the benefits of early mobilisation, reduced post-operative discomfort, and patient satisfaction.
