- Original description
In elderly patients undergoing arthroplasty surgery, postoperative recovery quality is closely related to preoperative physical reserve. Sarcopenia and reduced muscle quality can increase postoperative complications. This prospective observational study aims to investigate whether preoperative Handgrip Strength (HGS) and muscle stiffness measured by Shear Wave Elastography (SWE) can predict the quality of recovery at postoperative 24 hours (assessed via the Quality of Recovery-15 [QoR-15T] score) in patients aged 60 and older undergoing elective total knee or hip arthroplasty.Read full original descriptionShow less
The Impact of Preoperative Functional Reserve and Muscle Stiffness on Postoperative Quality of Recovery in Elective Lower Extremity Arthroplasty Surgeries
In elderly patients undergoing arthroplasty surgery, postoperative recovery quality is closely related to preoperative physical reserve. Sarcopenia and reduced muscle quality can increase postoperative complications. This prospective observational study aims to investigate whether preoperative Handgrip Strength (HGS) and muscle stiffness measured by Shear Wave Elastography (SWE) can predict the quality of recovery at postoperative 24 hours (assessed via the Quality of Recovery-15 [QoR-15T] score) in patients aged 60 and older undergoing elective total knee or hip arthroplasty.
Inclusion: Patients aged 60 years and older; Scheduled for elective unilateral total knee arthroplasty (TKA) or total hip arthroplasty (THA); American Society of Anesthesiologists (ASA) Physical Status classification I, II, or III; Six-Item Screener (SIS) score > 4 (indicating preserved baseline cognitive status); Voluntary participation with signed written informed consent.
Exclusion: Emergency surgical procedures; History of upper extremity surgery, trauma, or pathology precluding handgrip or biceps brachii measurement; Significant baseline cognitive impairment (Six-Item Screener [SIS] score ≤ 4); ASA Physical Status classification IV or V; Refusal to provide consent or withdrawal from the study.
