Early postoperative straight leg raise is associated with shorter length of stay after unilateral total knee arthroplasty

Abstract

Purpose: Shorter length of stay (LOS) after total knee arthroplasty (TKA) is cost-effective. Straight leg raise (SLR) is a common exercise prescribed after TKA, but the significance of early postoperative SLR is unknown. The primary aim of this study is to evaluate the association between early postoperative SLR and LOS. Secondary aims are to explore associations among early postoperative SLR, time to ambulation, and time to stairs climbing and identify factors related to postoperative SLR. Methods: 888 TKAs (888 knees, 865 patients) performed at a tertiary hospital in 2016 were included for this retrospective study. All TKAs were performed with medial parapatellar approach and tourniquet. Time to events (SLR, ambulation, stair climbing), LOS and factors influencing these events were analysed using a multivariate Poisson regression model and logistic regression. Results: Patients who performed SLR on postoperative day 1 (POD1) had shorter LOS than those who did not (adjusted Mean Ratio (aMR) = 0.846, p < 0.001), with estimated mean LOS being 3.5 days and 4.1 days, respectively. Performing SLR on POD1 was also associated with shorter time to ambulation (aMR = 0.789; p < 0.001) and stair climbing (aMR = 0.811, p < 0.001). Female gender and higher rest pain on POD1 were associated with delayed postoperative SLR. Conclusion: Performing SLR on POD1 after TKA is associated with shorter LOS, time to ambulation, and time to stair climbing. Early postoperative SLR can prognosticate early recovery and discharge. Optimization of preoperative muscle strength and postoperative pain may be important in early recovery after TKA.

Adductor Canal Block Does not Confer Better Immediate Postoperative Pain Relief after Total Knee Arthroplasty

“…19 In their study, Suh et al found that SLR was associated with shorter LOS and faster time to ambulation. 23 There were no statistically significant differences in patients' ability to actively perform SLR between groups in our study, which suggests that although the ACB likely confers some motor blockade, it is not enough to cause any significant weakness.…”

Efficacy of Tourniquet Use in Total Knee Arthroplasty: A Retrospective Cohort Review

“…Ishii et al. found no correlation of SLR to standing up and walking [ 16 ]; however, a more recent study found that the ability to perform an SLR on POD 1 led to decreased time to ambulation, stair climbing, and a decrease in length of stay in the hospital [ 17 ]. Our study demonstrated a statistically significant difference in the patient’s ability to perform an SLR on POD 1, with 100% of patients in the NT group able to SLR while only 77% of patients in the T group were able to SLR ( P < .001).…”

Rehabilitation of Geriatric Burn Patient Post-Meek Micrograft with Bilateral Partial Calcanectomy: A Case Report

“…Early rehabilitation in geriatric burn patients is crucial in mitigating complications, reducing duration of hospital stay, improving over-all strength, maximizing functional outcome, and quality of life. 9 Bedside exercises, such as straight leg raises, were essential in promoting strengthening of the quadriceps muscles, improving pain control, and promoting better functional recovery over time.…”
