Abstract
BACKGROUND Total knee arthroplasty (TKA) is a feasible and cost-effective procedure. However, resurfacing of the patella sparks a heated debate. Anterior knee pain after TKA was supposed to be correlated to the patellofemoral joint, and the resurface of the patella was believed to be effective to avoid this complication. AIM A meta-analysis was performed to update current evidence concerning the outcomes of patellar resurfacing versus retaining for total knee arthroplasty. The first outcomes of interest were to compare the rate of anterior knee pain and revision surgeries. MATERIAL AND METHODS This study was conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA). A comprehensive review of the literature was conducted accessing the main databases: Embase, Google Scholar, PubMed, Scopus. All the prospective clinical trials comparing the outcomes between patellar resurfacing versus retaining were included in this study. Only articles classified as level of evidence I to II were considered for inclusion. Only studies reporting a minimum 24 months follow-up were included. The following data were extracted: demographic baseline, anterior knee pain, reoperations, clinical scores (HSS, KSS and related subscales) and range of motion (ROM). Studies solely reporting quantitative data under the outcomes of interest were included. RESULTS In favor of the resurfacing group, we observed a statistically significant reduced rate of anterior knee pain (odd ratio 1.73) and reoperation (odd ratio 3.24). In the resurfacing group, a prevalence of anterior knee pain of 11.15% was detected, whereas in the retaining group it amounted to 17.39%. Furthermore, a greater KSS pain (+ 0.97%), KSS clinical (+ 0.23%), KSS functional (+ 2.44%), KSS overall (+ 2.47%) and HSS (+ 5.64%) were reported. In the retaining group, we found a better range of motion (+ 3.09°). CONCLUSION Based on the main findings of this meta-analysis, patellar resurfaced TKA was demonstrated to have performed superior overall. Patellar resurfacing detected a lower rate of postoperative anterior knee pain and reoperation. Moreover, the resurfacing group showed greater value of the HSS, KSS and related subscales. In favor of the retaining group, a slightly better ROM was evidenced. LEVEL OF EVIDENCE Level II, meta-analysis of prospective clinical trials.

Abstract
Total knee arthroplasty (TKA) is the best treatment for advanced knee osteoarthritis and it has proven to be durable and effective. Anterior knee pain (AKP) is still one of the most frequent complications after TKA, but sometimes no recognized macroscopic causes can be found. The correct treatment of patella is considered the key for a proper management of AKP. The inclusion of patellar resurfacing during TKA has been described as a potential method for the reduction of AKP. After surgeons started to resurface the patella, new complications emerged, such as component failure, instability, fracture, tendon rupture, and soft tissue impingement. Patelloplasty has been proposed as a good alternative to resurfacing but whether or not to resurface the patella is still a controversial topic in the literature. Therefore, patellofemoral joint is a complex critical aspect in TKA and choosing between the several options of treatment of patella could not be sufficient. In this review, evidence-based studies do not succeed in resolving this difficult argument. The accurate management of the so-called “third space” should include an accurate assessment of cartilage layers, balance of soft tissue, preoperative anterior tracking, and positioning of the femoral and tibial components. In fact, the selection of suitable implants and adherence to proper surgical technique are the fundamental principles for the success of TKA.

J Arthroplasty 2018; 33:1962-1971.e3. [PMID: 29398258 DOI: 10.1016/j.arth.2017.12.024] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2017] [Revised: 11/30/2017] [Accepted: 12/20/2017] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND A systematic review and meta-analysis was performed to investigate the risks associated with anterior knee pain (AKP) following primary total knee arthroplasty (TKA). METHODS A computerized search was performed of the following databases: MEDLINE, Embase, and Cochrane Central (published prior to July 2017). A total of 37 studies, which included 1641 cases of AKP and 168,090 TKAs, were included in the meta-analysis. RESULTS A subgroup analysis revealed that compared with those without the following medical conditions, patients who had an infrapatellar fat pad excision and more than 12 months of follow-up (odds ratio [OR] 12.58, 95% confidence interval [CI] 3.245-48.781) were more likely to have AKP after TKA. Circumpatellar electrocautery (>12 months: OR 0.50, 95% CI 0.326-0.760; ≤12 months: OR 0.59, 95% CI 0.408-0.867) and patellar resurfacing (OR 0.25, 95% CI 0.131-0.485) may decrease the risk of AKP. Other factors, including the prosthesis bearing type (mobile bearing or fixed bearing) and the approach (midvastus compared with the medial parapatellar approach), were not significant risk factors for AKP. CONCLUSION The use of strategies such as patellar denervation and patellar resurfacing in primary TKA is recommended because they are safe and result in good clinical outcomes in preventing AKP. Caution should be taken when using an infrapatellar fat pad excision, because there is an increased risk of AKP at long-term follow-up (>12 months). Future studies should investigate these different strategies to confirm the underlying mechanisms and help prevent the occurrence of AKP after TKA. The timing of AKP onset remains unclear and requires further research.

Abstract
INTRODUCTION We report a short-term monocentric retrospective evaluation of cementless total knee arthroplasty (TKA) in a population suffering from chronic inflammatory rheumatism. MATERIALS AND METHODS We have reviewed 23 patients (34 knees) with an average age of 55 years (range 26-78), bearing a TKA for chronic inflammatory rheumatisms with a 6-year follow-up (range 3-12); 78% suffered from rheumatoid arthritis and 15% from juvenile rheumatoid arthritis. We used a cementless total prosthesis sacrificing the posterior cruciate ligament and bearing an ultra-congruent rotational tibial insert, the Natural Knee (NK2™) (Zimmer(®), Warsaw, IN, USA). At last follow-up, an independent surgeon performed a clinical assessment for pain, function and quality of life using International Knee Documentation Committee score, International Knee Society (IKS) score and Devane's score. A radiographic study evaluated secondary fixation according to the radiographic index of the Knee Society and according to Ewald's score. RESULTS The mean postoperative IKS score was 83 points (range 40-100) for the knee score and 74 points (range 20-100) for the function score. Radiographic assessment came across only one case of loosening, concerning the tibial component on an asymptomatic patient. We came across the following complications: 1 early infection, 2 important postoperative flessum deformity having needed an arthrolysis, 1 supracondylar fracture of the femur and 1 fracture of the patellar component. Survival rate at 6-year follow-up is 97% taking into account one case of revision. CONCLUSION Non-cementation of this implant in chronic inflammatory rheumatism does not result in a higher rate of loosening. In this series, patients own satisfaction, function of the knee and survival rate are rather good. LEVEL OF EVIDENCE Retrospective, no control group, Level IV.

Abstract
OBJECTIVE To compare the results of primary total knee arthroplasty with patellar reshaping or resurfacing. METHODS One hundred thirty-three patients were randomized into patellar reshaping group and patellar resurfacing group. Patellar reshaping includes resecting the partial lateral facet of the patella and the osteophytes surrounding the patella, trimming the patella to match the trochlea of the femoral component. The minimum follow-up time was 7 years. The outcome was measured by anterior knee pain rate, Knee Society clinical score, and radiographs. RESULTS Eight patients in the reshaping group (12.5%) and 10 patients in the resurfacing group (14.7%) complained of anterior knee pain (P=0.712). Meanwhile, there were no significant differences between the two groups in terms of total Knee Society score, Knee Society pain score, Knee Society function score, as well as anterior knee pain rate. CONCLUSIONS With the numbers available, there was no significant difference between the groups treated with patellar reshaping or patellar resurfacing with regard to the KSS, anterior knee pain rate and radiographs. We prefer reshaping the patella to resurfacing the patella because the former preserves sufficient patellar bone stock and can easily be converted to patellar replacement if patients complain of recurrent anterior knee pain.

Validity of published outcome data concerning Anatomic Graduated Component total knee arthroplasty: a structured literature review including arthroplasty register data. INTERNATIONAL ORTHOPAEDICS 2011; 36:51-6. [PMID: 21487670 DOI: 10.1007/s00264-011-1255-1] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/19/2011] [Accepted: 03/23/2011] [Indexed: 10/18/2022]
Abstract
PURPOSE Total knee arthroplasty (TKA) as a treatment for end-stage osteoarthritis of the knee shows good results in terms of patient satisfaction. For the assessment of outcome and revision rate after total joint arthroplasty, there are two major data sources: clinical studies and national arthroplasty registers. The purpose of this study was to analyse the outcome of Anatomic Graduated Component (AGC) TKA reported in clinical studies and to perform a comparison with the outcome reported by national arthroplasty registers. METHODS A systematic literature review was performed using standardised methodology in order to determine the outcome and revision rate of AGC TKA. In a comprehensive meta-analysis of clinical studies and worldwide register results we examined the quality of the basic data and the occurrence and influence of potential bias factors. Confidence intervals were calculated to determine the statistical significance of differences. RESULTS We found significant differences as regards the revision rate measured in revisions per 100 observed component years. Compared to worldwide register data it turned out to be significantly lower in clinical studies published by the implant development team. Actually, they reported a revision rate of 0.18 revisions per 100 observed component years, whereas annual reports of national arthroplasty registers report 0.74 revisions per 100 observed component years. A comparison of the results from national arthroplasty registers of different countries revealed a significantly higher revision rate for Denmark in relation to worldwide register data. CONCLUSIONS A conventional meta-analysis of clinical studies is affected by the influence of the development team and therefore subject to bias. For the assessment of outcome arthroplasty register data should be rated as superior and, being used as reference data for the detection of potential bias factors in the clinical literature, could make an essential contribution to the quality of scientific meta-analysis.

Abstract
Controversies existing over resurfacing the patella in total knee arthroplasty remain in the literature. The purpose of this review was to evaluate the effectiveness of resurfacing versus nonresurfacing the patella in total knee arthroplasty. We searched the Cochrane Library, MEDLINE and EMBASE for published randomised clinical trials relevant to patellar resurfacing. The relative risk of reoperation was significantly lower for the patellar resurfacing group than for the nonresurfacing group (relative risk 0.57, 95% confidence interval 0.38-0.84, P =0.004). The overall incidence of postoperative anterior knee pain of the 1,421 knees included was 12.9% in the patellar resurfacing group and 24.1% in the nonresurfacing group. The existing evidence indicates that patellar resurfacing can reduce the risk of reoperation with no improvement in postoperative knee function or patient satisfaction over total knee arthroplasty without patellar resurfacing. Whether it can decrease the incidence of anterior knee pain remains uncertain.
