Morphine consumption, analgesic requirements, and visual analogue scale (VAS) assessments were significantly lower in group DL during the 24-hour period after surgery. The time to start CPM in the postoperative period was significantly shorter in group DL. Passive joint flexion angle was significantly higher in group DL. Postoperative straight leg lifting time was significantly shorter in group DL. Adding dexmedetomidine to the intra-articular levobupivacaine provided better postoperative pain control and improved rehabilitation period after ACL surgery.Haptic robotic-arm-assisted total knee arthroplasty (RATKA) seeks to leverage three-dimensional planning, intraoperative assessment of ligament laxity, and guided bone preparation to establish and achieve patient-specific targets for implant position. We sought to compare (1) operative details, (2) knee alignment, (3) recovery of knee function, and (4) complications during adoption of this technique to our experience with manual TKA. We compared 120 RATKAs performed between December 2016 and July 2018 to 120 consecutive manual TKAs performed between May 2015 and January 2017. Operative details, lengths of stay (LOS), and discharge dispositions were collected. Tibiofemoral angles, Knee Society Scores (KSS), and ranges of motion were assessed until 3 months postoperatively. Manipulations under anesthesia, complications, and reoperations were tabulated. Mean operative times were 22 minutes longer in RATKA (p  less then  0.001) for this early cohort, but decreased by 27 minutes (p  less then  0.001) from the first 25 RATKA cases to the last 25 RATKA cases. Less articular constraint was used to achieve stability in RATKA (93 vs. 55% cruciate-retaining, p  less then  0.001; 3 vs. 35% posterior stabilized (PS), p  less then  0.001; and 4 vs. 10% varus-valgus constrained, p_ = _0.127). RATKA had lower LOS (2.7 vs. 3.4 days, p  less then  0.001). Discharge dispositions, tibiofemoral angles, KSS, and knee flexion angles did not differ, but manipulations were less common in RATKAs (4 vs. 17%, p = 0.013). We observed less use of constraint, shorter LOS, and fewer manipulations under anesthesia in RATKA, with no increase in complications. Operative times were longer, particularly early in the learning curve, but improved with experience. All measured patient-centered outcomes were equivalent or favored the newer technique, suggesting that RATKA with patient-specific alignment targets does not compromise initial quality. Observed differences may relate to improved ligament balance or diminished need for ligament release.There is no consensus about which graft type should be used in patients who will undergo anterior cruciate ligament (ACL) reconstruction so far. In this study, it was aimed to compare the quality of life, knee functions, and isokinetic muscle strength of patients who underwent ACL reconstruction with hamstring tendon (HT) and bone-tendon-bone (BTB) autografts. Total 40 patients with ACL reconstruction (20 in HT group and 20 in BTB group), at least 1 year after the operation, all injured during sports activity were included in this study. Flexor and extensor muscle groups of both affected and unaffected knees at angular velocities of 60 and 180 degrees/s were recorded. Lysholm knee score questionnaire and Short Form (SF)-36 were administered to all patients before the isokinetic tests. No statistically significant differences were found between the groups at any angular velocity in isokinetic evaluation. Furthermore, there was no statistically significant difference between the groups in regard to Lysholm score. Palazestrant price However, there was a statistically significant difference between the groups in SF-36 physical function domain score (p  less then  0.01). The results demonstrated that the SF-36 questionnaire can easily be applied to this patient population. There was only one significant difference in the SF-36 physical function component scores between the two groups. The quality of life, knee functions, and isokinetic muscle strength were similar in patients who underwent ACL reconstruction with HT and BTB.Historically, intraoperative analysis of knee fracture procedures relied upon a fluoroscopic reduction assessment by the surgeon. This is a subjective assessment due to the lack of linear measurement reference data. Compared with the knee, the ankle and wrist have well-established bony anatomical relationships to guide reduction assessment during fracture treatment. The purpose of this study was to (1) determine the width ratios in the knee (plateau to femur) with aging, and (2) determine knee width changes with aging. One-hundred and fifty consecutive uninjured knee radiographs were reviewed. In all age groups, the width ratio of the articular distal femoral (ADF) to the articular tibial plateau (ATP) is greater than 1.0 and between 1.03 and 1.05. The tibia plateau width is on average 9.34 mm wider and the femoral width is 8.0 mm wider in the 61 to 80 age group than the ATP and the ADF in the younger age groups. In conclusion, the articular tibial plateau width and the articular distal femoral width are nearly equal across ages 20 to 80 years. An absolute articular width value by age cannot be assigned because articular widths change with aging.The primary purpose of this study was to study and compare rates of two salvage operations for patients with chronically infected total knee arthroplasties (1) knee arthrodesis and (2) above knee amputation (AKA). An analysis was performed comparing the inpatient hospital characteristics and complications between the two procedures. Secondarily, we presented rates of all surgically treated periprosthetic total knee infections over a 6-year period. Using the Nationwide Inpatient Sample, we identified all patients with a periprosthetic infection (International Classification of Diseases, Ninth Revision [ICD-9] 996.66) from 2009 to 2014. Subsequently, we identified surgically treated total knee infections through the following ICD-9 codes 00.80 (all component revision), 00.84 (liner exchange), 80.06 (removal of prosthesis), 84.17 (AKA), and 81.22 (knee fusion). From 2009 to 2014, the annual incidence of surgically treated total knee periprosthetic infections increased by 34.9% nationally, while the annual incidence of primary total knees increased by only 13.
