Aims The aim of this study was to determine whether closed suction drain (CSD) use influences recovery of quadriceps strength and to examine the effects of drain use on secondary outcomes: quadriceps activation, intra-articular effusion, bioelectrical measure of swelling, range of movement (ROM), pain, and wound healing complications. Patients and Methods A total of 29 patients undergoing simultaneous bilateral total knee arthroplasty (TKA) were enrolled in a prospective, randomized blinded study. Patients were randomized to receive a CSD in one limb while the contralateral limb had the use of a subcutaneous drain (SCDRN) without the use of suction (‘sham drain’). Isometric quadriceps strength was collected as the primary outcome. Secondary outcomes consisted of quadriceps activation, intra-articular effusion measured via ultrasound, lower limb swelling measured with bioelectrical impendence and limb girth, knee ROM, and pain. Outcomes were assessed preoperatively and postoperatively at day two, two and six weeks, and three months. Differences between limbs were determined using paired Student’s t-tests or Wilcoxon’s signed-rank tests. Results No significant differences were identified between limbs prior to surgery for the primary or secondary outcomes. No significant differences in quadriceps strength were seen between CSD and SCDRN limbs at postoperative day two (p = 0.09), two weeks (primary endpoint) (p = 0.7), six weeks (p = 0.3), or three months (p = 0.5). The secondary outcome of knee extension ROM was significantly greater in the CSD limb compared with the SCDRN (p = 0.01) at two weeks following surgery, but this difference was absent at all other intervals. Secondary outcomes of quadriceps activation, intra-articular effusion, lower limb swelling, and pain were not found to differ significantly at any timepoint following surgery. Conclusion The use of CSD during TKA did not influence quadriceps strength, quadriceps activation, intra-articular effusion, lower limb swelling, ROM, or pain. These results have limited drain use by the authors in primary uncomplicated TKA. Cite this article: Bone Joint J 2019;101-B (7 Supple C):84–90

AbstractWe aimed to investigate the effect of the knee position during the surgical closure on isokinetic muscle strength, clinical score, and range of motion in total knee arthroplasty. Seventy-five eligible patients were enrolled in the study and randomly divided into two groups; wound closure was performed with the knee flexed at 90° in group 1 and knee extended in group 2. All the surgeries were performed by the same surgeon and by the same prosthesis type. All the patients received the same rehabilitation program postoperatively. The primary outcomes were the knee flexion degrees and the American Knee Society Score values at preoperative and postoperative 6 weeks, 3, and 6 months. The secondary outcome was the isokinetic muscle strength measurements of both knees before the surgery and after 6 months. There were no significant differences in the American Knee Society Scores and knee flexion degrees between the flexion and extension groups. However, a significant decrease was found in the extensor muscle strength in the extension group after 6 months of the surgery. The findings of our study are that the closing of the knee in flexion or extension does not affect the postoperative knee flexion degrees and scores in total knee arthroplasty. However, quadriceps strength recovers early if the knee closure is performed in flexion position.

AbstractShort CommunicationsSevere post-operative pain is common after total knee arthroplasty. Patient-controlled analgesia is an alternative method of pain management, whereby a patient administers his or her own pain medication. Patients seem to prefer this method over nurse-administered analgesia. However, it remains unclear whether patients using patient-controlled analgesia devices use higher or lower doses of opioids compared to patients treated with oral opioids.Objectives and MethodsThis retrospective study examined 164 patients undergoing total knee arthroplasty. Post-operatively, 82 patients received oxycodone via intravenous patient-controlled analgesia devices, while the pain medication for 82 patients in the control group was administered by nurses. The main outcome measure was the consumption of intravenous opioid equivalents within 24 h after surgery. Secondary outcome measures were the use of anti-emetic drugs and the length of stay. Furthermore, we evaluated opioid-related adverse event reports.ResultsThe consumption of opioids during the first 24 h after surgery and the use of anti-emetic drugs were similar in both groups. The median opioid dose of intravenous morphine equivalents was 41.1 mg (interquartile range (IQR): 29.5–69.1 mg) in the patient-controlled analgesia group and 40.5 mg (IQR: 32.4–48.6 mg) in the control group, respectively. The median length of stay was 2 days (IQR: 2–3 days) in the patient-controlled analgesia group and 3 days (IQR: 2–3 days) in the control group (p=0.02). The use of anti-emetic drugs was similar in both groups.ConclusionsThe administration of oxycodone via intravenous patient-controlled analgesia devices does not lead to increased opioid or anti-emetic consumptions compared to nurse-administered pain medication after total knee arthroplasty. Patient-controlled analgesia might lead to shortened length of stay.

Test Retest Reliability

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.
