Table 1 Different minimally invasive approaches for THA

DAA (direct anterior approach)

8–10-cm incision; no cut to the muscles and tendons; anterior capsule removed; need special table or apparatus; femoral implant limited due to poor exposure

Direct lateral

8–10-cm incision; cut gluteus medius and gluteus minimus; limp in some cases postoperation

Posterolateral

6–8-cm incision; split gluteus medius; limited exposure limp in some cases postoperation

Two incisions

Acetabular component placement through an anterior incision and femoral component through an a small posterior incision; longer operation time; sheer learn curve; procedure complexity
