This study aimed to determine differences in functional recovery after total hip arthroplasty between a group of patients operated on using a direct lateral approach, an anterolateral minimally invasive approach, and a posterior approach to the hip joint. Arthroplasty is the most commonly performed surgical procedure in orthopedics and is also considered the gold standard for treating the final stage of osteoarthritis. There are several different approaches, but there are still conflicting studies that talk about the benefits of a particular approach. There is an insufficient number of scientific, prospective studies that monitor the basic functional and rehabilitation parameters, which are also indicators of the success of the performed procedure.
