Summary
Removing postoperative restrictions after total hip arthroplasty (THA) does not increase dislocation risk. This study confirms a low incidence of dislocation in patients undergoing primary THA without early functional restrictions.
Area of Science:
- Orthopedic Surgery
- Arthroplasty Research
- Patient Rehabilitation Protocols
Background:
- Previous research indicated no increased dislocation risk after removing functional restrictions post-primary total hip arthroplasty (THA).
- Current practice guidelines require updated evidence on dislocation incidence following THA with no-restriction protocols.
Purpose of the Study:
- To evaluate the incidence of early dislocation after primary THA under a no-restriction postoperative protocol.
- To inform current practice guidelines for THA patient management.
Main Methods:
- A cohort of 2532 patients (2764 hips) underwent primary THA between 2005 and 2007 using direct anterior or anterolateral approaches.
- Patients received no traditional functional restrictions (e.g., elevated seats, abduction pillows).
- Follow-up was conducted on 2386 patients (2612 hips) for a minimum of 6 months.
Main Results:
- A low incidence of dislocation (0.15%, 4 hips) was observed in the followed cohort.
- Dislocations occurred at a mean of 5 days postoperatively and were not related to high-impact trauma.
- Specific cases included a patient with hip dysplasia, two during toileting, and one idiopathic dislocation.
Conclusions:
- A no-restriction protocol is associated with a low incidence of early dislocation after primary THA.
- The findings support the safety of omitting early postoperative functional restrictions in primary THA patients.
