“…It is pointed out that the changes of proprioceptive sensation and neuromuscular control are the main reasons of these effects [14]. Keitkamp et al have indicated that balance training can significantly increase the standing time of one leg on the unstable interface, but strength training cannot enhance it [15]. Meanwhile, balance training can increase the maximum contractile strength of knee flexion and extension under isokinetic condition.…”

Background. Total knee arthroplasty is one of the most effective methods for the treatment of end-stage knee osteoarthritis, but 10% of patients still show insufficient function, strength, and mobility. Continuous nursing service plays an important role in the rehabilitation of patients undergoing total knee arthroplasty. For discharged and convalescent patients, the traditional follow-up model cannot solve the nursing problems of discharged patients. How to meet the health needs of discharged patients under the limited nursing resources has become an existing problem. Objective. To explore the effect of proprioception and balance training combined with continuous nursing on Berg balance scale (BBS) score and Hospital for Special Surgery (HSS) score of patients undergoing total knee arthroplasty (TKA) is the objective of this study. Methods. Sixty patients undergoing TKA in our hospital from December 2019 to April 2021 were enrolled. The patients were randomly assigned into the control group and the study group. The control group received continuous nursing, and the study group received proprioception and balance training combined with continuous nursing. Results. The nursing satisfaction of the study group was higher than that of the control group ( P < 0.05 ). The HSS scores at discharge, 1 month, 3 months, and 6 months after discharge in the study group were higher than those in the control group ( P < 0.05 ). It was higher in the study group than in the control group at 1 month, 3 months, and 6 months after discharge ( P < 0.05 ). The pain catastrophizing score of the study group at discharge was lower than that of the control group at 1 month, 3 months, and 6 months after discharge ( P < 0.05 ). The BBS scores at discharge, 1 month, 3 months, and 6 months after discharge in the study group were higher than those in the control group ( P < 0.05 ). The Lindmark balance scores at discharge, 1 month, 3 months, and 6 months after discharge in the study group were lower than those in the control group ( P < 0.05 ). Conclusion. Proprioception and balance training combined with continuous nursing can effectively promote the recovery of knee joint function of patients after TKA, enhance patients’ pain catastrophizing grade, enhance patients’ quality of life, effectively promote patients’ knee joint function and BBS score, and promote the improvement of disease.

“…Surgeons performing total knee arthroplasty (TKA) and considering different alignment options and instrumentation are interested in the accuracy and time it takes to make the distal and posterior femoral bone resections that determine the setting of the femoral component [ 7 ]. Technology proponents argue that robotic, navigation, and patient-specific instrumentation more accurately hit the femoral target than manual instruments [ 12 , 14 , 22 , 28 ]. Whereas manual instrument proponents argue that technology lengthens the operation, adds expense, and induces stacked errors arising from transforming images into a 3D model, planning the resection planes, and registering instruments [ 1 , 4 , 5 ].…”

Purpose Surgeons performing total knee arthroplasty (TKA) are interested in the accuracy and time it takes to make the four femoral resections that determine the setting of the femoral component. A method for quantifying the error of each resection is the thickness, measured by a caliper, minus the femoral target. The present study tested the hypothesis that the mean deviation of the resection from the femoral target, the percentage of resections with a deviation of ± 0.5, 1.0, 1.5, and 2.0 mm, and the time to complete the femoral cuts were not different between experienced (E) and less-experienced (LE) surgeons performing unrestricted caliper verified kinematically aligned (KA) TKA with manual instruments. Methods This study analyzed intraoperative verification worksheets from 203 patients treated by ten E surgeons and 58 patients treated by four LE surgeons. The worksheet recorded (1) the thickness of the femoral target for the distal medial (DM), distal lateral (DL), posterior medial (PM), and posterior lateral (PL) resections and the caliper thickness of the resections with a resolution of 0.5 mm, and (2) the time to complete them. The most accurate resection has a mean difference ± standard deviation of 0 ± 0.0 mm. Results The accuracy of the 1044 initial resections (261 patients) was significantly closer to the femoral target for E vs. the LE surgeons: 0.0 ± 0.4 vs. − 0.3 ± 0.5 for the DM, 0.0 ± 0.5 vs. − 0.4 ± 0.6 for the DL, − 0.1 ± 0.5 vs. − 0.2 ± 0.5 PM, and − 0.1 ± 0.5 vs. − 0.4 ± 0.6 for the PL resections (p ≤ 0.0248). E surgeons completed the femoral resections in 12 min; 5 min faster than LE surgeons (p < 0.0001). Conclusions Because the mean difference in femoral resections with manual instruments for E vs. LE surgeons was < 0.5 mm which is within the caliper’s resolution, differences in accuracy were not clinically relevant. Surgeons exploring other alignment options and robotic, navigation, and patient-specific instrumentation might find these values helpful when deciding to change. Level of evidence III; case–control study.

“…In order to achieve that, a computer-assisted, pinless navigation device (Knee 2.6, Brainlab AG, Feldkirchen, Germany) was used for 30 patients. The accuracy of this system has already been investigated in several studies and was verified to be a precise and reliable pinless navigation system [ 7 , 8 , 9 , 10 ]. The setup consisted of a stand-alone computer with infrared cameras, controlled by a touch screen, and a pointer with reflector spheres as well as a reflector array.…”

Purpose: In contrast to total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA) is a true resurfacing procedure, as none of the ligaments are replaced or released, and the pre-arthritic leg alignment is the major goal. As such, the alignment of the tibial component plays a crucial role in postoperative knee function and long-term survival. Pinless navigation has shown reliable results in total knee arthroplasty. To the best of our knowledge, the use of pinless navigation has not been investigated for UKA. Therefore, the present study investigated whether implantation of the tibial component in 3° varus, which is closer to the anatomical axis, is feasible with a pinless optical navigation system. Methods: 60 patients with the diagnosis of an unicompartmental arthritis, were eligible for UKA and treated with implantation in 3° varus alignment of the tibial component. Two groups were established. In the treatment group the tibial component was aligned using a pinless navigation technique. In the control group, a conventional extramedullary alignment guide was used. A clinical and radiographic follow up took place within 1 year of operation. Results: 57 Patients were eligible for analysis. No clinical incidents were noted in the follow up period. The desired target value, the position of the tibial component, was accurately achieved with an average of 3° medial inclination using the pinless navigation as well as using the conventional technique. Mean incision to suture time was negligible between the two techniques. The mean suture time was 43.2 min with pinless navigation and 42.7 min with the conventional technique. Conclusions: With pinless navigation in UKA, a method was presented that made it possible to achieve sled prosthesis alignment at the level of a high-volume surgeon. These results were achieved with an irrelevant increase of surgical time and without placement of pins.
