Summary
Preoperative testosterone therapy in older men undergoing knee replacement surgery showed a trend toward reduced hospital stays and improved early functional recovery, particularly in standing ability. Further research is recommended to confirm these benefits.
Area of Science:
- Orthopedic Surgery
- Endocrinology
- Geriatric Medicine
Background:
- Older patients often experience slower recovery and extended rehabilitation after knee replacement surgery.
- Supraphysiological testosterone (T) administration is known to significantly increase muscle strength.
Purpose of the Study:
- To investigate the hypothesis that preoperative testosterone therapy improves functional recovery in older men undergoing knee replacement.
- To assess the impact of preoperative testosterone therapy on hospital stay duration in this patient group.
Main Methods:
- A double-blinded, placebo-controlled pilot trial was conducted.
- Twenty-five male participants, with a mean age of 70, received either supraphysiological testosterone (600 mg T enanthate weekly for 4 weeks) or a placebo before elective knee replacement surgery.
- Outcomes measured included length of hospital stay and functional ability assessed by the Functional Independence Measure (FIM) score.
Main Results:
- The testosterone group showed a nonsignificant reduction in mean hospital stay (5.9 days vs. 6.8 days, P = .15).
- Significant improvement in the ability to stand was observed on postoperative Day 3 in the testosterone group (mean FIM score 5.2 vs. 4.0, P = .04).
- Trends towards improved walking and stair climbing were noted, with no complications attributed to testosterone therapy.
Conclusions:
- Preoperative supraphysiological testosterone administration may offer clinical benefits for older men undergoing knee replacement surgery.
- Larger studies with extended preoperative testosterone courses are warranted to validate these findings in older surgical patients.
