CRISTALJAMA 2022
Effect of Aspirin vs Enoxaparin on Symptomatic Venous Thromboembolism in Patients Undergoing Hip or Knee Arthroplasty: The CRISTAL Randomized Trial.
Aspirin failed to show non-inferiority and was associated with a significantly higher rate of symptomatic VTE than enoxaparin, mainly driven by below-knee DVT. There was no significant difference in death or major bleeding.

Aspirin or Rivaroxaban for VTE Prophylaxis after Hip or Knee Arthroplasty.
Aspirin was non-inferior to rivaroxaban for symptomatic VTE, with low event rates in both groups. There was no significant difference in major or clinically relevant bleeding.

Dislocations after total hip-replacement arthroplasties.
Cups within about 15 degrees (plus or minus 10) of anteversion and 40 degrees (plus or minus 10) of inclination dislocated less often than those outside this 'safe zone'; increased anteversion was linked to anterior dislocation, and risk was highest early after surgery and in previously operated hips.
