PurposeThe aim was to compare active heel‐slide exercise (AHSE) + standard physiotherapy (PT) to continuous passive motion (CPM) + standard PT during inpatient rehabilitation of total knee arthroplasty (TKA) patients in terms of postoperative outcomes. MethodsPatients were randomly assigned into AHSE or CPM groups. Both groups received standard PT (range of motion and strengthening exercises, and ambulation) during hospital stay. Patients were evaluated regarding functional outcomes, knee proprioception, pain intensity, active range of motion, knee circumference, length of hospital stay, time for achieving straight leg raise actively, time for achieving 70° knee flexion. ResultsGroups were similar at baseline (n.s.). At discharge, AHSE group was better in terms of pain intensity (p < 0.001), Hospital for Special Surgery knee score (p = 0.001), rise from sitting (p = 0.015), ascend/descend stairs (p = 0.038), and timed up and go test (p = 0.028) compared to CPM group. AHSE group was able to perform the straight leg raise earlier than CPM group during inpatient period (p = 0.001) and demonstrated improved proprioception at discharge and at 3‐month follow‐up (p < 0.05). No statistical differences were detected between groups in other evaluation parameters (n.s.). ConclusionOur findings support AHSE therapy offers a more functional rehabilitation and leads beneficial results for patients following TKA. Therefore, active exercise approach encouraging patients to participate in their rehabilitation should be first choice in acute postoperative rehabilitation following TKA rather than CPM.

Local infiltration analgesia (LIA) is a simple, surgeon-administered technique for the treatment of postoperative pain after total knee arthroplasty (TKA). The aim of the study was to investigate the efficacy of LIA and its effects on functional outcomes in TKA. A total of 135 patients with primary TKA were recruited and randomized either to receive LIA or to receive placebo injection (PI). Pain, active range of motion (ROM), knee function score, functional activities, and hospital length of stay (LOS) were assessed before surgery and from postoperative day (POD) 1 to at discharge. Lower pain scores at rest were recorded on POD1 and POD2 in the LIA group (p = 0.027 and p = 0.020, respectively). Lower pain score on walking was recorded on POD1 in the LIA group (p = 0.002). There was a statistically significant difference in active knee flexion between groups on POD1 (p = 0.038). There was a significant difference in LOS between LIA and PI groups. Shorter stay was seen in LIA group. There were no statistically significant differences between the groups in terms of knee function score and functional outcomes. LIA technique is effective for pain management in the early postoperative period. LIA added benefit for knee function in terms of active knee flexion ROM after TKA. A shorter hospital LOS was observed in LIA group. However, we did not find any differences in groups in terms of functional assessment such as ability to rise from a chair and walking capacity.The level of evidence is randomized controlled trial, level I.
Purpose This study aimed to compare progressive muscle relaxation (PMR) + standard physiotherapy (PT) to standard PT during inpatient rehabilitation of total knee arthroplasty (TKA) patients in terms of post-operative outcomes. The hypothesis was that PMR + standard PT would lead to better pain, function, and neuromuscular outcomes than standard PT. Methods A total of 106 patients were randomly allocated into PMR or standard rehabilitation (SR) groups. Both groups received standard PT during their hospital stay. PMR group additionally performed PMR exercise on post-operative days 1, 2, and 3. Patients were evaluated regarding pain intensity, functional outcomes, muscle strength, active range of motion, knee edema, anxiety, depression, and kinesiophobia. Results There were no diferences between groups at baseline (n.s.). During the inpatient period and at discharge, the PMR group had better results in terms of pain relief (p < 0.05), quadriceps strength (p = 0.001), kinesiophobia level (p = 0.011) compared to the SR group. No diference was detected between groups regarding other evaluation parameters during the inpatient period, at discharge, and third post-operative month (n.s.). The within-group analysis showed statistically signiicant diferences over time in both groups in each variable (p < 0.05). Conclusion Our indings support that PMR therapy ofers beneicial results in subjective and objective measures of TKA patients during the inpatient period. Therefore, PMR therapy could be implemented into the rehabilitation program of TKA patients to enhance their early recovery from various symptoms following TKA. Level of evidence II.
Background:Patients with TKA show impairments in standing balance up to 1 year after surgery. The impaired standing balance in TKA patients was found to be associated with falls risk and decreased functional level. Assessing of standing balance with objective and reliable assessments tools would therefore be extremely useful for determining accurate exercise program, and risks of falling, especially during the rehabilitative period when ambulation is at its most unsteady (1, 2). The stepping maneuver requires adequate strength and motor control to stabilize the body over the stance limb while the other leg is stepping, therefore the Step Test (ST) provides significant information for dynamic standing balance and lower limb motor control (3). The reliability of ST is reported in patient groups such as stroke, however, there is not any study that investigates the reliability of ST in patients with TKA in the current literature.Objectives:The purposes of this study were to determine the test-retest reliability and the minimal detectable change (MDC) of the ST in patients with TKA.Methods:40 patients with TKA due to knee osteoarthritis, operated by the same surgeon, were included in this study. Patients performed trials for ST twice on the same day. Between the first and second trials, patients waited for an hour on sitting position to prevent fatigue. The ST assesses an individual’s ability to place one foot onto a 7.5-cm-high step and then back down to the floor repeatedly as fast as possible for 15 seconds. The score is the number of steps completed in the 15-second period for each lower extremity. Scores for each lower extremity were recorded separately. Prior to the testing, the ST was demonstrated by the tester and all participants were allowed to a practice trial.Results:The ST showed an excellent test-retest reliability (ICC2,1=0.95) in this study. Standard error of measurement (SEM) and MDC95for ST were 0.37 and 1.02, respectively.Conclusion:This study found that the ST has an excellent test–retest reliability in patients with TKA. It is an effective and reliable tool for measuring dynamic standing balance and participant falls. As a performance-based clinical test, the ST is easy to score, can be applied in a short time as part of the routine medical examination. Therefore, inclusion of ST into a more comprehensive battery of performance-based measures of standing balance and lower limb motor control function in subjects with TKA should be considered.References:[1]Si, H.
