Purpose:
To determine if hip movement precautions reduce hip prosthesis dislocation rates post hip arthroplasty using a posterior surgical approach compared to minimal or no movement restrictions.
Materials And Methods:
This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered prospectively. CINAHL, MEDLINE and Embase were searched from inception until September 2020 supplemented by citation tracking. Studies were included if patients had a hip arthroplasty using a posterior surgical approach with comparative data on hip movement precautions or minimal to no movement restrictions. Methodological quality was evaluated using the Downs and Black checklist.
Results:
From a yield of 8 studies, meta-analysis of 7 studies and 9599 total hip arthroplasties, there was low quality evidence of no increased risk of dislocation (RR = 0.98, 95%CI 0.58 to 1.67) for patients prescribed minimal or no hip movement restrictions compared with patients prescribed hip movement precautions. There were 121/5440 dislocations (2.2%) in the movement precaution group and 90/4159 dislocations in the minimally restricted group (2.2%).
Conclusions:
Dislocation rates after total hip arthroplasty are low irrespective of movement precaution allocation. Resources allocated to implementing hip movement precautions may be better directed towards other clinical areas.IMPLICATIONS FOR REHABILITATIONThere was no difference in hip prosthesis dislocation rate between patients who received hip movement precautions compared to patients who received minimal or no restrictions after total hip arthroplasty using a posterior surgical approach.Health professionals involved in prescribing and monitoring adherence to hip movement precautions after total hip arthroplasty may be better allocating their resources to other areas of clinical care.Falls were associated with the greatest number of prosthesis dislocations, accounting for 24% of dislocations; resources may be better allocated towards evidence-based strategies to reduce falls.
