Introduction: Robotic-assisted TKA has shown promise in recent years by sharpening the Orthopaedic surgeon’s armoury, allowing the surgeon to reproduce technical excellence via accurate component placement and restoration of the ideal hip-knee-ankle (HKA) mechanical axis consistently and safely. However, the lack of high quality long-term evidence demonstrating its efficacy, unnecessary preoperative radiation, longer operating times and questionable cost-effectiveness have stifled the adoption of robotic systems. In our previous study comparing robotic-assisted versus conventional total knee arthroplasty (TKA), no differences in short-term functional outcomes were observed, despite reduction of radiological outliers. Our patients have now been prospectively followed for two years postoperatively, providing us with an opportunity to evaluate the functional outcomes of robotic-assisted TKA. Objectives: This study aims to determine any functional outcome differences between robotic-assisted and conventional TKA at two years follow-up. Methods: All 60 knees (31 robotic-assisted; 29 conventional) from the initial study cohort were available for analysis. Differences in range of motion, Knee Society (KSS) knee and function scores, Oxford Knee scores (OKS), SF-36 subscale and summative …show more content…
Despite having a higher rate of complications, the robotic-assisted group displayed a trend towards higher scores in SF-36 Quality-of-Life (QOL) measures, with significant differences in SF-36 vitality (p=0.03), role emotional (p=0.02) and a larger proportion of patients achieving SF-36 vitality MCID (48.4% vs 13.8%, p = 0.009). No significant differences in KSS, OKS or satisfaction/expectation rates were noted. The robot-assisted group had a total of 5 complications in 4 patients and the conventional group had 2 complications in 2
The results of the study showed that for perceived physical functioning patients recovered from less than 50% preoperatively to about 80% of that of controls 6-8 months post-surgery. On functional capacity, patients recovered from 70% preoperatively to 80% of that of controls 6-8 months post-surgery. For daily activity, patients recovered from 80% preoperatively to 84% of that of controls at 6 months post-surgery.
Objectives: The aim of this study was to compare these aspects between 2 groups of patients who underwent TKA using CAS or CI, respectively, at a minimum of 10 years follow-up.
Objectives: The purpose of this study was to evaluate the impact of MR versus GR knee design on the kinematics and kinetics of the knee during level ground walking one year after total knee arthroplasty.
These have all been shown to beneficial following knee replacement surgery. Two studies performed by Bade and Stevens-Lapsley found that strength training of the quadriceps and hamstrings following TKA resulted in better long-term outcomes and better performance in functional activities.5,6 Ebert et al. found that manual drainage massage was beneficial for reducing pain and increasing knee ROM after knee replacement surgery.7 According to Brugioni, patellar mobilization is critical for maintaining adequate knee ROM after undergoing a total knee replacement surgery. Gait mechanics and ambulatory endurance are often altered by knee surgery, and therefore, requires gait training to be corrected. Bruin-Olsen et al. found that a specific walking-skill program had better outcomes than traditional physiotherapy after TKA.9 Finally, Storey and colleagues found that indoor and outdoor walking tests moderately correlated with functional walking ability following TKA, which is important to keep in mind when choosing the right clinical objective
When a person is 20% or more over the ideal body weight they are categorized as obese1. The patient also has DJD which made her a poor candidate for the procedure; many times these patients are recommended not to have TKAs 1(p1). Obese patients tend to have total knee replacements at younger ages. 2 The procedure may be more challenging for the surgeon because of difficulty identifying anatomical landmarks.2 (p27) One study from Clinical Orthopaedics and Related Research2 (p26) found that super-obese patients were approximately 3.1 times more likely to experience complications when compared to those of normal weight. Intraoperative complications such as fractures and nerve damage are uncommon in a TKA5 (780). Infection, joint instability, polyethylene wear, and component loosening are several postoperative complications5 (780). Reported finding2 (26) show that super-obese patients had an approximately 9.4 times higher chance of implant loosening that would require revision. Implant loosening typically occurs at the tibial component and with cementless or hybrid TKAs5 (780). As previously mentioned, the patient wanted to work towards meeting several long term goals. She wanted to lose weight, and regain a normal schedule with her job and family. Losing weight would significantly increase her chances of a successful TKA. Since the
The fifth article critiqued is the first update of a clinical practice guideline (CPG) authored by the American Academy of Orthopedic Surgeons (AAOS). The purpose of this systematic review is to evaluate the best available evidence associated with nonsurgical treatment of knee OA. To be included in this study, the subjects must be original research treating knee OA with pain, function, and disability status as the primary outcome measures. Studies were excluded based on design and if they were of very limited strength of evidence. The authors searched the databases PubMed, EMBASE, CINAHL, and Cochrane Register of Controlled Trials. The recommendations in this CPG are based upon the evidence found in these studies. When critiquing the articles, the authors analyzed the quality and applicability of the studies using the Grade Evidence Appraisal System and the PRECIS Instrument. The authors made the following recommendations for braces and insoles.
This study also looked at postoperative pain and analgesic consumption, surgical time and visibility, and intraoperative blood loss. However, the strengths and limitations of this study were evaluated based on how the study was conducted in order to obtain results for knee ROM and functional outcomes. The study had many strengths, including its randomization of patients, its inclusion and exclusion criteria (Figure 1), it was single blind in that patients were not aware of whether their tourniquet was inflated during surgery or not, all surgical techniques were standardized, the same equipment was used for each procedure, and the same physician performed all TKA surgeries. The limitations of the study included the following: the randomization of patients was selected from a previous study, the population size was small (n = 70), and it was unable to be a double blinded study due to the fact that the physician would know regardless of being told whether the tourniquet had been inflated or not depending on the amount of blood in the surgical field.
As the commonality is increasing in proximal tibial osteotomy, imagine being born with the deformity which leads to abnormal distribution of weight bearing stress on your knee. In recent years, there have been new methods discovered for these procedures each of which has certain advantages and disadvantages. This proximal tibial osteotomy procedure is commonly used to realign knee structure no matter what the diagnosis has been. However, physical therapy is a crucial part that goes hand-in-hand with surgery, and for one to understand its function, it is also prominent to apprehend the general recovery process of physical therapy. With this in mind, there are three effective ways to approach the proximal tibial wedge osteotomy: high tibial
All patients included in the study were recalled for subjective, objective, and functional evaluation; the study protocol involved the range of motion (ROM), ligamentous stability, Tegner-Lysholm Score, Modified Cincinnati Rating System Questionnaire, Short Form-12 (SF-12) in addition to the plain radiograph, computed tomography (CT), and magnetic resonance imaging (MRI) of the knee. According to international knee documentation committee (IKDC) score, any development of arthrosis was assessed at the final follow-up.
Objectives: The objective of the current study is to evaluate longitudinally QOL assessed by the JKOM and objective outcomes assessed by the Knee Society Score (KSS) and the Timed Up and Go Test (TUG) for 5 years after bilateral TKA. In addition, QOL and objective outcomes are compared between younger (less than 80 years old at the final follow-up) and older (80 years old or more) age groups.
A total knee replacement (TKA) is the most common joint surgery performed in the United States (Turner, 2011, pp. 27-32). Each year, over 650,000 Americans undergo this surgery (Wittig-Wells, 2015, pp. 45-49). It is an invasive surgery that involves an incision on top of the knee and replacing damaged parts of the knee with artificial parts that are either metal, ceramic or plastic. Someone would get a total knee replacement for damage of the joint, osteoarthritic, posttraumatic, or inflammatory arthritis. The cartilage is damaged, wears away and then you develop bony deformity and contracture of ligaments but it starts out with specific defects or wear of cartilage. The top nursing priorities for a total knee arthroplasty is to “prevent complications, promote optimal mobility, alleviate pain, and provide information about diagnosis, prognosis, and treatment needs” (Doenges, 2014, pg. 627). A possible nursing diagnosis from the patient who is undergoing a TKA might be ‘impaired physical mobility related to pain and discomfort as evidenced by reluctance to attempt movement.’ Another one could be ‘acute pain related to chronic joint disease as evidenced by reports of pain’ (Vera, 2014).
The CRA-method for rotational alignment of the femoral component in TKA is accurate and precise, and there is no need for special instruments or additional preoperative
Methods: After IRB approval, 49 patients who underwent right TKA were prospectively evaluated. All patients underwent a preoperative BRT assessment, and then were tested again at 2, 4 and 6 weeks post-op. At each testing each patient where
et al. also state that immediate postoperative phase starts frome days 1-7 after surgery. The objective was to eliminate pain and swelling, achieve full active knee extension equal to the uninvolved side, restore the ability to control the leg while weight bearing, achieve at least 125˚ of knee flexion. From the main article, author also state that strengthening exercise such as running was allowed at 3-6 months with progressive squatting exercise. The study by Gereon Berschin. et al. also state that for lower extremity strength, the use of squat or squat position was mostly used this guarantees a synergistic activation of knee extensor and flexor groups, thus co-activating the hamstring. From the main article, the author state the knee joint condition at the preoperative and the latest follow-up period was evaluated based on side-to-side differences between the injured and uninjured leg. Test that used by examiners was Lachman test, pivot shift test, poeterior drawer test, manual valgus test, the lysholm knee scale and visual analogue scale (VAS) during follow-up time. This
The measurement of quality of life provides objective evaluations of how and how much the disease influences patients’ life and how patients cope with it. These evaluations may be used as a baseline of outcome measures and should provide framework to determine the impact of any change on patients’ quality of life after surgery.
