A study to assess the clinical and functional outcome of sub-vastus approach for total knee arthroplasty

Background Osteoarthritis and rheumatoid arthritis affects all patients of age more than 50 years, requiring total knee replacement. There are two major approaches to total knee replacement- sub-vastus approach and medial parapatellar approach. There is no common consensus on superiority of sub-vastus approach. So, we undertook the present study to evaluate the functional and clinical outcome of total knee replacement via sub-vastus approach in terms of knee society clinical and functional scores and visual analog scale along with monitoring of range of motion in the post-operative knee in the follow up period.

Methods The present prospective and observational study was conducted in the Department of Orthopaedics, Unique Super Speciality Hospital, Indore, Madhya Pradesh for a period of 12 from June 2019-May 2020 with sample size of 30 patients undergoing total knee arthroplasty. All the patients had undergone total knee replacement via sub-vastus approach. The functional and clinical results of our study were compared with available literature.

Results The mean KFS and KCS scores showed a statistically significant improvement over a period of 12 months (p 0.05).

Conclusions On comparing the results of sub-vastus approach with the available literature we found a significant improvement in functional and clinical outcome with a stable improvement in range of motion with very few complications.
