Pre-surgery knee joint loading patterns during walking predict the presence and severity of anterior knee pain after total knee arthroplasty

Introduction: Anterior knee pain following total knee arthroplasty is estimated to occur in 4-49% of patients. Some orthopedic surgeons use circumpatellar electrocautery (diathermy) to reduce the prevalence of postsurgical anterior knee pain; however, the extent of its use is unknown. Materials and Methodology: In April 2009, a postal questionnaire was sent to all 98 departments of orthopedic surgery in The Netherlands. The questions focused on the frequency of total knee arthroplasties, patellar resurfacing, and the use of circumpatellar electrocautery. Results: The response rate was 92%. A total of 18,876 TKAs, 2,096 unicompartmental knee arthroplasties, and 215 patellofemoral arthroplasties are performed yearly in The Netherlands by the responding orthopedic surgeons. Of the orthopedic surgeons performing TKA, 13% always use patellar resurfacing in total knee arthroplasty for osteoarthritis, 49% use selective patellar resurfacing, and 38% never use it. Fifty-six percent of orthopedic surgeons use circumpatellar electrocautery when not resurfacing the patella, and 32% use electrocautery when resurfacing the patella. Conclusion: There is no consensus among Dutch orthopedic surgeons on the use of patellar resurfacing or circumpatellar electrocautery in total knee replacement performed for osteoarthritis. A prospective clinical trial is currently underway to fully evaluate the effect of circumpatellar electrocautery on the prevalence of anterior knee pain following total knee arthroplasty.

Background: Anterior knee pain (AKP) following total knee arthroplasty (TKA) is one of the complication which cause dissatisfaction in patients. Incidence estimated to be 4-49%. The aim of our study is to know the efficacy of patelloplasty with circumpatellar denervation with diathermy in reducing AKP in primary TKA.Methods: A total of 130 unilateral TKAs’ are divided into 2 groups. Group I (control) includes 65 patients in which only patelloplasty was done. Group II (intervention) includes 65 patients in which both patelloplasty and circumpatellar denervation with diathermy was done and analysed. Mean follow up period was 18 months. Patients were assessed both preoperatively and postoperatively at final follow up.Results: The overall incidence of AKP at follow up (18 months) was 16.9%, with 7.7% in the intervention group and 26.1% in the control group (p<0.05). Western Ontario and McMaster Universities osteoarthritis index scores were significantly better in intervention group when compared to control group (28.71±3.948 vs 31.40±3.860). Better results were also found in knee society scores for intervention group compared to control group (166.57±7.941 vs 161.23±11.219); Feller patellar score of intervention group was significantly better when compared to control group (23.28±2.546 vs 20.69±3.729); the range of knee flexion was similar in both the groups (94.62±12.6 vs 93.54±10.7). In terms of pain referred by the patient at 72 hrs postoperatively, there was statistically significant difference observed according to visual analogue scale.Conclusions: There is statistically significant difference with respect to AKP in patients who have undergone patelloplasty with circumpatellar denervation using diathermy compared with patelloplasty alone.

Abstract Background Anterior knee pain (AKP) is the most common complication of total knee arthroplasty (TKA). It is unclear which procedure of addressing AKP is preferable. Some data suggest patellar denervation (PD) provides effective AKP prevention. The purpose was to assess the effectiveness and safety of PD in primary TKA.Methods A meta-analysis was performed of randomized clinical trials (RCTs) from inception to March 26, 2020, using PubMed, Embase, Web of Science and Cochrane Library. Study-specific RR and MD were aggregated using random or fixed effects models. The outcomes were incidences of AKP, PS (patellar scores), VAS (visual analogue scale), ROM (range of motion), KSS knee (American Knee Society knee scores), KSS function (American Knee Society function scores), incidence of complications and revisions.Results Ten RCTs involving 1196 knees were included. The meta-analysis showed no significant in PD group on the incidence of AKP (RR = 0.64; 95% CI 0.37, 1.11; p = 0.11) with moderate heterogeneity (P < 0.01, I2 = 84%). Our results indicated PD had a significantly better VAS (MD = − 0.25; 95% CI -0.41, -0.09; p < 0.01), ROM (MD = 7.68; 95% CI 0.34, 15.20; p = 0.04) and PS (MD = 0.91; 95% CI 0.36, 1.46; p < 0.01). However, there was no significant difference no matter in KSS knee, KSS function, complications or revisions.Conclusions This meta-analysis showed that no difference in AKP between PD and NPD in patients undergoing non-resurfaced TKA. PD could improve clinical outcome in VAS, post-operative ROM and PS.
