Abstract

Background: Total knee arthroplasty (TKA) is a surgical procedure designed to alleviate pain and improve function in patients suffering from osteoarthritis. Range of motion is one of the most important factors for patient satisfaction after total knee replacement. The purpose of this study was to assess the effectiveness of a new TKA technique involving patellar resection to enable increased flexion of the knee joint.

Methods: Eighty-four patients suffering from osteoarthritis with an indication for conducting TKA underwent the novel procedure. Pre-operative and post-operative flexion measurements were assessed.

Results: Mean age of patients participating in this study was 62 years. Males and females were 63% and 37 % of total population respectively. The mean pre-operative and post-operative flexion measurements were 97.39±3.33 º and 131.35±4.27 respectively. The mean in flexion measurements was improved by 33.95±5.30 º (p<0.05). The joint was kinematically stable during full flexion, mid-flexion, and extension.

Conclusions: The novel patellar resection technique can be beneficial for the patients. They can able to follow their native lifestyle and perform their daily activities without any hindrance. The mean increase in the range of flexion was 33.95±5.30 º (ranged 30-35 º, p<0.05). This technique allowed patients to have a greater range of flexion as compared to standard and high flexion designs.
