“…These values seem higher and exceeds reported FJS scores in healthy adults with no knee issues [9]. When mobile and fixed bearing TKSs were compared with follow up of three years, scores were found to be 77.2 and 61.9, which are comparable to our findings [34].…”

Background: There have been multiple ways to measure outcomes post total knee arthroplasty. Ultimate goal is to replicate a natural joint to allow patients to perform most activities of daily living and give high satisfaction rates. Patient reported outcome measures (PROM) like Forgotten Joint Score (FJS), Oxford Knee Score (OKS)and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) have been validated and used for evaluation of TKA patients. FJS helps to evaluate how natural a prosthesis feels post surgery. Our aim was to study how natural a joint felt or was forgotten 2 year after surgery and how FJS correlates with OKS and WOMAC scores. Materials and Methods : We evaluated 254 total knee replacements with minimum 2 year post TKA. All the patients who were at least 2 year post operative, completed FJS questionnaire where scores are ranged from 0-100; OKS questionnaire where scores are ranged between 0-48; Short – form WOMAC questionnaire where scores are ranged between 0-28. Correlation analysis was performed for FJS with OKS and short - form WOMAC scores. Results: 254 patients with mean age of 65.01 years of which 83 males and 171 females were evaluated with minimum of 24 months follow up and average follow-up of 30.85 months. Average FJS, OKS and SF WOMAC were 77.24, 38.75 & 79.97 respectively. FJS showed good correlation with OKS and SF WOMAC scores. Conclusion : FJS is an easy and equally effective outcome measure, which is valid and reliable like the other common well know measures like OKS and WOMAC. Patients experience a marked improvement in the FJS over the first two years. Patients in our series had good outcomes who had more natural feel of knees or a feeling of “forgotten knees” in their day to day activity after 2 years of surgery.

“…Mean age was 65.01 (28-91) years. All patients in the study had minimum follow up of 24 months with average follow up of 30.85 (24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38) months. Of the total knees 55.12% were left sided and 44.88% were right, in our group 10.63% of patients had valgus knees who underwent TKA.…”

“…Kim et al also reported no influence of PCO and PCOR on flexion angle PCL sacrificing TKA with study involving two groups one with 1.2-mm reduction in the PCO and the other with any reduction. Similar results were found in studies done by Rajshekar K [23] Hanratty et al [24] and Bauer et al [25] on PCL sacrificing TKA whereas Arabori et al [26] on PCL substituting TKA. The significance of PCO appears to be less in the posterior stabilized or posterior-sacrificing knee prosthesis as per the previous studies.…”

Background: Osteoarthritis of the knee is a common clinical problem that affects elderly and few young individuals. It is associated with symptoms like pain, stiffness and limitation of activity. Total Knee Arthroplasty is an effective surgical modality that reduces pain, improves patients' quality of life, and increases functional capability in patients with severe osteoarthritis of knee. Role of Posterior Condylar Offset on Range of movements has always been a controversial topic. The present study has been taken up by us because studies conducted by western authors reported conflicting outcomes. Materials and Methods:This was a prospective study in which Patients with diagnosis of osteoarthritis knee presenting in Department of Orthopaedics at a tertiary care hospital and willing to undergo surgery were included depending upon inclusion and exclusion criteria. Assessment of knee was done preoperatively and postoperatively to obtain functional outcome of TKA clinically by using knee society score and oxford knee score and radiologically to obtain PCO and PCOR. Results: We found no significant correlation between post-operative Posterior Condylar Offset (mean 25.94+/-1.89), Posterior Condylar Offset Ratio (mean 0.45+/-0.02) with Maximum Flexion Angle (mean115.93+/-9.59) with p value 0.136 and 0.995 respectively. Conclusion: Maximum flexion angle after Total Knee Arthroplasty is a multivariate hence Posterior Condylar Offset and Posterior Condylar Offset Ratio cannot be used as an independent variable for the quantification of functional outcome of Total Knee Arthroplasty. Moreover, accurate radiographic measurement of pre-operative Posterior Condylar Offset is not possible as the cartilage thickness remained was not accounted for and also there is an inherent error in the measurement techniques that accounts for inconsistent findings.

“…Several studies have compared patients’ outcomes with PCL-preserved or sacrificed TKA; generally, no significant differences were described between the two groups of patients [ 34 , 43 , 44 , 45 ]. Thippanne et al [ 43 ] reported no statistically significant differences for FJS between 169 PCL-retained TKAs and 178 PCL-sacrificed TKAs. Similarly, Bieganowski et al [ 44 ] compared mean postoperative FJS in 671 TKAs; 236 were treated with a PCL preservation implant and 435 were treated with a posterior stabilized prosthesis.…”

In the last decades, several surgical techniques, such as medial pivot (MP) philosophy and kinematic alignment (KA), have been introduced in total knee arthroplasty (TKA) to improve patients’ outcomes. This retrospective study aims to evaluate the clinical, radiographic, and functional results of PCL preservation or sacrifice in KA MP-TKA. A consecutive series of 147 patients older than 60, with a minimum follow-up of two years, were treated with TKA for severe primary knee osteoarthritis (OA) at the Department of Orthopedics and Traumatology between 1 January 2019, and 1 July 2020. After excluding those not meeting the inclusion criteria, 64 patients were included in the study analysis. Regarding radiographic outcomes, no statistically significant difference was observed between patients with preserved or sacrificed PCL (p > 0.05). A slight improvement in Knee Society Score (KSS), knee and function score, and FJS was observed for the PCL-preserved group, although this superiority tendency was not statistically significant (p > 0.05). PCL-preserved MA MP-TKA reported a statistically significant result in only two questions on the FJS questionnaire (p < 0.05). A slight, non-statistically significant improvement in active ROM was found in the PCL-sacrificed group (p > 0.05). No interventions or revisions were reported in this case series for all treated patients at the final follow-up. No significant differences were described in clinical, radiographic, and functional outcomes in preserved or sacrificed PCL KA MP-TKA. Although not significant, a slight trend toward better clinical outcomes was reported in PCL-preserved KA MP-TKA.
