Key result
A 10-day postoperative/preoperative hemoglobin ratio <85% was associated with a significant difference in postoperative straight leg raise strength at 2 months compared to a ratio ≧85%.
Why the study?
Does postoperative anemia (Hb ratio <85%) affect hip muscle strength recovery in patients undergoing THA?
Observational (n=82)
Does postoperative anemia (Hb ratio <85%) affect hip muscle strength recovery in patients undergoing THA?
Postoperative anemia, defined by a postoperative/preoperative Hb ratio <85%, is associated with impaired recovery of hip muscle strength after total hip arthroplasty.
Answers are grounded in this paper and cite their sources.
May impair hip strength recovery after THA; hypothesis-generating and requires randomized confirmation before practice change.
BACKGROUND: The presence/absence of postoperative anemia are presumed to have an impact on early recovery after surgery. This study was performed to compare hip muscle strength and hemoglobin during the perioperative period in 82 patients undergoing THA. METHODS: Evaluation of presence/absence of anemia was performed by calculating the 10-day postoperative/preoperative Hb ratio. Muscle strength was investigated before and 2 months after surgery. RESULTS: Postoperative SLR strength showed a significant difference between the patients whose 10-day postoperative/preoperative Hb ratio was <85% and ≧ 85%. CONCLUSION: We need to consider perioperative strategies to minimize anemia in order to improve patient outcomes.

Maezawa et al. (2018) conducted an observational in Total hip arthroplasty (n=82). 10-day postoperative/preoperative hemoglobin ratio <85% vs. 10-day postoperative/preoperative hemoglobin ratio ≧85% was evaluated on Postoperative straight leg raise (SLR) strength at 2 months. A 10-day postoperative/preoperative hemoglobin ratio <85% was associated with a significant difference in postoperative straight leg raise strength at 2 months compared to a ratio ≧85%.
