ABSTRACT

Medial parapatellar approach is the arthrotomy technique most commonly used for total knee arthroplasty; to avoid the disadvantages of this, minimally invasive approaches can be performed, such as the subvastus approach, of which less vascular injury has been reported in the literature. The objective of the present work was to identify the difference of transoperative bleeding from the subvastus approach versus the medial parapatellar approach in primary total knee arthroplasty. Methods: We retrospectively studied 69 patients who underwent primary total knee arthroplasty during the period from January 1, 2017 to May 1, 2018, of the 44 (63.77%) had medial parapatellar surgical approach and 25 patients (36.23%) subvastus approach. The trans surgical bleeding between both approaches was sought as the main variable. Results: The quantified bleeding for the medial parapatellar approach had a mean of 862 ml and a standard deviation of 269 ml, for the subvastus approach a mean of 487 ml and a standard deviation of 141 ml with a p value = 0.018. Conclusion: We identified a lower blood loss by performing the subvastus approach compared to the medial parapatellar approach (862 ml vs 487 ml).
