[Conventional vs minimally invasive total hip arthroplasty. A prospective study of rehabilitation and complications]
1Orthopedic Surgery, Center for Computer Assisted and Reconstructive Surgery, Tufts University School of Medicine, Harvard Medical School, New England Baptist Hospital, 125 Parker Hill Avenue Suite 545, Boston, MA 02120, USA.
Background:
In a prospective, nonrandomized study the outcome in terms of rehabilitation and complications of total hip arthroplasty (THA) through a superior capsulotomy exposure (study group) was compared to THA performed through a direct lateral exposure (control group).
Patients And Methods:
The study group (106 THA) and the control group (107 THA) were controlled for complexity and had no significant differences in age, sex, diagnosis, or body mass index.
Results:
The study group had improved recovery at 6 weeks after surgery which was statistically significant (p<0.001). In addition, the study group had a lower incidence of perioperative complications.
Conclusion:
The current study demonstrates the potential that less-invasive surgical techniques with the philosophy of maximally preserving the abductors, posterior capsule, and short rotators may result in a safer operation with an accelerated recovery.
