Among many factors such as age, body mass index, pain intensity, and limb strength, it turns out that walking speed was the most significant factor. According to the study, patients who can walk at a speed of 1 meter per second, or about 3.5 kilometers per hour, are most likely to achieve the best surgical outcomes. This applies to pain relief, improved functional ability, and even the ability to forget about the artificial joint in daily life. As hip replacement techniques evolve and their success rates increase worldwide, a recent Japanese study reveals a simple yet highly influential factor in determining surgical outcomes and recovery quality: walking speed before the operation.
