In the study, “Is Cemented or Cementless Femoral Stem Fixation More Durable in Patients Older Than 75 Years of Age? A Comparison of the Best-performing Stem,” the word “cementless” was used in several locations where the word “cemented” was intended. The corrected sentences are listed here (with the word changes marked in bold type):
In the Questions/purposes section of the Abstract, the second question should be: “(2) Are there any diagnoses (such as osteoarthritis [OA] or femoral neck hip fracture) in which the three best-performing cementless stems had better survivorship than one of the three best-performing cemented stems?”
In the Methods section of the Abstract, the sentence should be: “Likewise, among patients with OA and femoral neck fracture, the cumulative percent revision was consistently higher at 1 month postoperatively among those treated with one of the three best-performing cementless stems than those treated with one of the three best-performing cemented stems (OA: HR for best three cementless versus best three cemented = 8.82 [95% CI, 5.08-15.31], p < 0.001; hip fracture: HR for best 3 cementless versus best three cemented = 27.78 [95% CI, 1.39-143.3], p < 0.001).”
In the Introduction, the question should be: “(2) Are there any diagnoses (such as osteoarthritis [OA] or femoral neck hip fracture) in which the three best-performing cementless stems had better survivorship than one of the three best-performing cemented stems?”
In the Results section, the sentence should be: “Likewise, among patients with OA (Fig. 3) and femoral neck fracture (Fig. 4) who were older than 75 years of age, the CPR was consistently higher at 1 month postoperatively among those treated with one of the three best-performing cementless stems than those treated with one of the three best-performing cemented stems (OA: HR for best three cementless versus best three cemented = 8.82 [95% CI, 5.08-15.31], p < 0.001; hip fracture: HR for best three cementless versus best three cemented = 27.78 [95% CI, 1.39-143.3], p < 0.001).”
In the Discussion section, the corrected sentence should be: “In femoral neck fractures, the CPR was consistently higher at 1 month postoperatively among those treated with one of the three best-performing cementless stems than those treated with one of the three best-performing cemented stems.”
The authors apologize for the errors.
