Will Total Knee Replacement Ever Provide Normal Knee Function?

AbstractKnee osteoarthritis or gonarthrosis is considered the most common joint disease, affecting more than 70% of subjects aged over 65 years. Its occurrence is increasing with age and is more problematic with the current rise in the incidence of obesity. In severe and advanced cases, total knee arthroplasty is recommended as a gold standard therapy for pain relief, restoration of normal knee function, and quality of life improvement. There are numerous controversies whether total knee arthroplasty is able to reach and provide end-point outcomes and restore previous function of the knee joint. Studies suggest that the surgeons’ experience, type of prosthesis used, associated pathology, underlying pathologies, risk factors, continuous passive movement, and patient expectations about the surgery may influence the outcomes to a great extent. “Normal knee function” is a statement that is hardly defined in the current literature, as authors usually refer to subjective results when analyzing outcomes. Objective results may be more straightforward, but they do not always symbolize the actual state that the patient is reporting or the actual quality of life. Our objective was to analyze and present summaries of the current literature regarding normal knee function restoration after total knee replacement surgery. Our literature review results confirm the hypothesis that subjective and objective results are difficult to interpret and unravel. Complex future trials may bring supplementary and clearer conclusions regarding knee function and kinematics, clinical improvement, patient satisfaction, and quality of life.

Knee Pathology

According to epidemiological studies, osteoarthritis accounts for 10–12 % of all cases of musculoskeletal diseases. In the general structure of knee pathology, degenerative diseases make up 57.8 %. The urgency of the problems of gonarthrosis is due to not only its widespread prevalence, but also the high risk of developing knee dysfunction, accompanied by a significant reduction in the quality of life of patients and often leading to partial or permanent disability of patients. Gonarthrosis has significant gender features. Women account for about 70 % of the number of patients, while men had this disease almost 2 times less often, but other data indicate that the incidence of gonarthrosis in men under 60 years of age is higher, and in women it begins to increase after 65 years. Knee replacement is a leading method in the treatment of knee osteoarthritis stages III–IV. The tendency towards an increase in the total number of surgeries leads to an increase in the frequency of complications and unsatisfactory results: according to some authors, from 3.3 to 13.2 % of patients complain of knee replacement outcomes. Studies of long-term complaints after arthroplasty have shown that in addition to pain reduction, some patients had an increase in varus angle when bending the knee while walking but they didn’t mark an improvement in gait parameters compared to preoperative examination. After unilateral total knee arthroplasty, the load patterns of the frontal plane in the operated knee remain pathological in the long run. After knee arthroplasty, there is muscle weakness, and studies have shown changes in all muscles of the lower extremity. Weakening of some muscles led to compensatory strengthening of others. Studies of the effect of preoperative rehabilitation on the outcome of knee arthroplasty have shown its low efficiency. Many studies have studied motor activity of patients after total knee arthroplasty in recent years. Not only gait features, but also movements of the pelvis, trunk and upper extremities are studied. Modern methods of diagnosing spatial oscillations of the body when walking have shown that disorders of body movements — excessive hand movements, pelvic loosening, asymmetrical flexion of the knee joints, etc., after arthroplasty are preserved in patients and restore slowly, and some disorders remain forever. Conclusions. Knee arthroplasty relieves pain, improves quality of life, but according to many authors, patients complain of incomplete restoration of the functionality of the prosthetic limb. According to the researchers, the main cause for incomplete reco-very of gait parameters is the difference in the frontal angles of the knee joint flexion and the difference in the length of the steps. Special training exercises can reduce the asymmetry of the steps, but it is difficult to completely restore the symmetry of the steps within 2 years. Studies of the effect of preoperative rehabilitation on the outcome of knee arthroplasty have shown its low effectiveness.

Summary Purpose Purpose of this retrospective study was to evaluate our own results after total knee replacement in patients with haemophilia. Patients, material, method: 30 patients with haemophilia who underwent total knee replacement between 1987 and 2005 were included. We used the clinical and radiological Knee Society Score. Furthermore, the Petterson and the Arnold and Hilgartner score were applied. Results: The mean age at the time of surgery was 43.2 (27–66). At the time of follow- up examination the mean age was 51.6 (30–82) years. The mean follow-up was 7.1 (2–20) years. Preoperative, he mean Arnold and Hilgartner score was 4.17 (± 0.59) and the mean Petterson-Score was 9 ± 2.29. Compared to the preoperative deficiency in knee function (KSS-Score 88.17 ± 33.58) an improvement with 166.67 (± 22.73) points was seen. 1 patient showed an aseptic loosening after 11 years. Discussion: Total knee replacement in patients with haemophilia improves knee function and quality of life. The results of our study represent results in earlier published studies. Compared to a non-haemo-philic normal population the rate of perioper-ative complications was not increased.

Abstract Background: To identify patients’ self-reported health-related quality of life (HRQoL) before and after total knee arthroplasty (TKA) and determine factors contributing to any heterogeneity in HRQoL. Methods: This prospective multicentre study included 404 patients with knee osteoarthritis who underwent TKA between 1 April and 30 December 2019 and in whom HRQoL was assessed preoperatively and at 7 days and 1, 3, and 6 months postoperatively. Sociodemographic characteristics were assessed using a general information questionnaire; disability, using the Knee Injury and Osteoarthritis Outcome Score; pain, using the visual analogue scale (VAS) score; and HRQoL, using the European Quality of Life Five Dimension Five Level (EQ-5D-5L) score. Potential heterogeneity and factors influencing longitudinal changes in HRQoL were analysed using a growth mixture model.Results: The mean EQ-5D-5L score improved from 0.69 preoperatively to 0.90 at 6 months postoperatively. Two types of longitudinal heterogeneity were identified: (1) a group of patients with a small and slow improvement in HRQoL and (2) a group of patients who showed marked and rapid improvement in HRQoL. The main characteristics of the latter group were a monthly family income >2000 yuan, exercising for approximately 30 min daily, and better knee function at baseline. Baseline knee function and change in knee function were significantly associated with the percentage change in HRQoL.Conclusions: HRQoL improved considerably after TKA. However, there was some heterogeneity in the changes in HRQoL depending on certain patient characteristics. Targeted interventions should focus on these differences to optimise the outcomes of TKA.

Abstract Background The purpose of this study was to determine the mid-term clinical, radiographic and health-related quality of life (HRQoL) outcomes and define the survival rate in patients who had undergone revision total knee arthroplasty (TKA) using the single rotating hinged knee (RHK) design. Methods Between January 2004 and December 2013, 125 revision TKAs were performed at our institution using the single RHK implant. We conducted both a retrospective analysis of prospectively collected outcome data of these patients and a prospective follow-up study of all 39 living patients (41 knees). The follow-up phase included an optional extra follow-up visit, PROM questionnaires, and plain radiographs. Results The ten-year Kaplan-Meier survival rate of the revision RHK knees was 81.7% (95% CI 71.9–91.6%) with re-revision for any reason as the endpoint. Overall, 15 knees (12% of the total) underwent re-revision surgery during the follow-up. The median follow-up was 6.2 years (range, 0–12.7 years) post-operatively for the baseline group. One mechanical hinge mechanism-related failure occurred without any history of trauma or infection. At the time of the final follow-up, the majority of patients evinced a fairly good clinical outcome measured with patient-reported outcome measures and none of the components were radiographically loose. Conclusion We found that in patients undergoing complex revision TKA, fairly good functional outcome and quality of life can be achieved using an RHK implant. Further, it seems that in this type of patient cohort, revision TKA using an RHK implant relieves pain more than it improves ability to function. The NexGen® RHK design can be regarded as a suitable option in complex revision TKA.

There is known to be a decrease in quality of life and perceived occupational performance and satisfaction following total knee arthroplasty (TKA). This study was planned to examine the effectiveness of a client-centered (CC) intervention with the telerehabilitation (TR) method on the quality of life, perceived occupational performance, and satisfaction after TKA. A total of 38 patients who had undergone TKA were randomly assigned to the CC and control groups. A 12-day intervention program was applied to the CC group. The Nottingham Health Profile (NHP) and Canadian Occupational Performance Measure (COPM) were applied before and after intervention. The 12-day intervention showed a strong effect on all parameters in the CC group ( p<.001). In the postintervention comparisons, a significant difference was found in favor of the CC group ( p < .001). CC interventions with the TR method can be used in post-TKA interventions.

AimsThis study investigated the influence of body mass index (BMI) on patients’ function and quality of life ten years after total knee arthroplasty (TKA).Patients and MethodsA total of 126 patients who underwent unilateral TKA in 2006 were prospectively included in this retrospective study. They were categorized into two groups based on BMI: < 30 kg/m2(control) and ≥ 30 kg/m2(obese). Functional outcome was assessed using the Knee Society Function Score (KSFS), Knee Society Knee Score (KSKS), and Oxford Knee Score (OKS). Quality of life was assessed using the Physical (PCS) and Mental Component Scores (MCS) of the 36-Item Short-Form Health Survey.ResultsPatients in the obese group underwent TKA at a younger age (mean, 63.0 years, sd 8.0) compared with the control group (mean, 65.6 years, sd 7.6; p = 0.03). Preoperatively, both groups had comparable functional and quality-of-life scores. Ten years postoperatively, the control group had significantly higher OKS and MCS compared with the obese group (OKS, mean 18 (sd 5) vs mean 22 (sd 10), p = 0.03; MCS, mean 56 (sd 10) vs mean 50 (sd 11), p = 0.01). After applying multiple linear regression with the various outcomes scores as dependent variables and age, gender, and Charlson Comorbidity Index as independent variables, there was a clear association between obesity and poorer outcome in KSFS, OKS, and MCS at ten years postoperatively (p < 0.01 in both KSFS and OKS, and p = 0.03 in MCS). Both groups had a high satisfaction rate (97.8% in the control group vs 87.9% in the obese group, p = 0.11) and fulfillment of expectations at ten years (98.9% in the control group vs 100% in the obese group, p = 0.32).ConclusionAlthough both obese and non-obese patients have significant improvements in function and quality of life postoperatively, obese patients tend to have smaller improvements in the OKS and MCS ten years postoperatively. It is important to counsel patients on the importance of weight management to achieve a more sustained outcome after TKA. Cite this article: Bone Joint J 2018;100-B:579–83.
