Intro- For TKA, there are two types of bearing designs: xed-bearing and mobile-bearing. Round femoral components articulate with a relatively at tibial articular surface in a xed-bearing knee design. Because the insert does not hinder the natural movements of the femoral component, the mobile-bearing (MB) TKA design is thought to allow more exibility of motion than the xed-bearing (FB) variety. Aim and objective: To compare xed bearing and mobile bearing total knee arthroplasty. Material and methods:This study is a prospective type of study done at Seth GS medical college Mumbai, Department of Orthopaedics during August 2019 to June 2021 on patients undergoing total knee arthroplasty. Patients who were to undergo total knee arthroplasty were invited to take part in the study. This study, done on them was explained in detail to them. An informed consent was obtained. Patients fullling the inclusion criteria were listed. Result: Range of motion achieved after mobile arthroplasty was 123.62±2.94 and in xed arthroplasty it was 121.96±2.74. Pain after last follow up in mobile arthroplasty was 48.83±0.62 and for xed arthroplasty was 47.39±0.86. Flexion gap after last follow up in mobile arthroplasty was 24.13±0.45 and in xed was 24.02±0.45. Stability was almost similar in both mobile and xed arthroplasty. Conclusions: there is no signicant difference between xed arthroplasty and mobile arthroplasty as far as Range of motion, Pain ,Flexion gap. Stability was almost similar in both mobile and xed arthroplasty.

INTRODUCTION Debate has persisted for many years about whether to sacrifice or replace the posterior cruciate ligament when performing total knee arthroplasty. A paucity of long-term follow-up studies comparing outcomes between cruciate-retaining and posterior-stabilised knees exist. We aimed to compare results at ten-year follow-up. METHODS A matched paired study comparing a cohort of 107 Zimmer Nexgen® Cruciate Retaining (CR) patients with a cohort of 107 Nexgen Posterior-Stabilised (PS) knees matched for age, sex, body mass index and preoperative American Knee Society score was undertaken. All patients underwent independent clinical assessment and knee society scoring preoperatively and at 1, 3, 5, 7 and 10 years postoperatively. RESULTS Fifty-three patients (49.5%) in the CR group and 44 patients (41.1%) in the PS group were alive at 10-year follow-up. There were no significant differences between the CR and PS groups with regards to functional assessment (P = 0.95), overall range of movement (P = 0.46) or patient satisfaction (P = 1.0) at 10 years. However, there was a significantly better score improvement in range of movement in PS knees compared with CR knees (P = 0.027). There were six revisions (5.6%) in the PS group and 1 (0.93%) in the CR group (P = 0.12). Both CR and PS knees showed excellent survivorship with no significant difference at 10 years (P = 0.068). CONCLUSIONS There were no significant differences in functional score, overall range of motion or patient satisfaction between the Nexgen cruciate retaining and posterior stabilised total knee arthroplasty at 10-year follow-up. However, PS knees had a greater score improvement in range of motion compared with CR knees.

Bearing Design

Total knee arthroplasty using navigation system is known to be more effective than conventional methods in achieving more accurate bone resection and neutral alignment.1 Mobile bearing is also known to reduce wear and automatically correct rotational malalignment of the tibia but the long-term follow-up results of more than 10 years are extremely rare.2, 3 The purpose of this study is to investigate the results of clinical and radiologic long-term follow-up and complications of total knee arthroplasty using navigation and multi-directional mobile bearing.From 2003 to 2006, a total of 111 navigation TKAs using multi-directional mobile bearing design were carried out and reviewed retrospectively. TKAs were performed by two experienced surgeons at one institute. Of the 111 patients, 102 were women and 9 were men. The mean duration of follow-up was 11.4 ± 1.0 years (range, 10.1 to 14.08 years). Clinical outcomes were evaluated in terms of Knee Society Score, Hospital for Special Surgery score, Western Ontario and McMaster University (WOMAC) score, range of motion and complications. Long-term radiological outcomes and survival rates were evaluated at least 10 years.Average preoperative HSS score was 66.5 ± 9.8 and KSS pain and function score were 25.0 ± 11.8 and 44.5 ± 12.3, respectively. Scores improved to 94.1 ± 8.2, 46.6 ± 11.6 and 88.2 ± 14.6 at the last follow up, respectively. Mean preoperative WOMAC scores of 75.8 ± 16.5 improved to 13.8 ± 16.0 at last follow-up. Five knees required re-operation, two for liner breakage, one for liner wear, one for distal femoral fracture and one for infection. The estimated 10-year prosthesis survival rates for any reason and for prosthesis-related problems were 95.5% and 97.4% , respectively.TKAs using each techniques resulted in similar good clinical outcomes and postoperative leg alignments. Robotic and navigation TKA appeared to reduce the number of postoperative leg alignment outliers and revision rate compared to conventional TKA.

The main objective of the current study was to evaluate the success of arthroscopic arthrolysis treatment of patients with knee stiffness after total knee arthroplasty. Six patients who underwent arthroscopic arthrolysis were evaluated retrospectively, all of them being treated conservatively before going for surgery. Results showed significant improvement of range of motion and Knee Society Score at the latest follow up compared to the preoperative values. This study concludes that arthroscopic arthrolysis is an effective and reproductible technique for the treatment of knees stiffness after total knee arthroplasty.

Background and Methods: Postoperative complications may impair the outcome of total knee arthroplasty (TKA). Patellar instability is a major cause of postoperative pain and functional limitation for which revision surgery may be necessary [1]. It may occur after TKA with or without patellar resurfacing. RESULTS AND CONCLUSIONS: Subluxation is more common than dislocation; the incidence of symptomatic instability leading to revision is low (0.5 to 0.8%) [2, 3]. In a multicentre study of low contact stress mobile bearing TKAs, only 6 of 259 revisions were associated with patellar instability, which accounted for a revision rate of 0.1% after a mean follow-up duration of 5.7 years [4]. A revision rate of 12% was reported secondary to complications of the extensor mechanism [5]. The aetiology of patellofemoral instability can be related to (1) the surgical technique and component positioning, (2) extensor mechanism imbalance, and (3) other causes.

Purpose. To compare the mid-term clinical outcomes in Indian patients after total knee arthroplasty (TKA) using a fixed- or mobile-bearing prosthesis. Methods. 120 consecutive patients (50 men and 70 women) aged 55 to 76 (mean, 63) years who had arthritis of the knee with similar deformity and range of motion were randomised to undergo TKA using a fixed- or mobile-bearing prosthesis. Patients with mediolateral instability and infective arthritis were excluded. Knee Society knee and functional scores, range of motion, and the presence of flexion contracture were assessed. Results. The mean follow-up duration was 3.5 (range, 1–4.6) years. The mid-term outcome of the 2 groups was comparable. One patient with a mobile-bearing prosthesis had recurrent dislocation at postoperative week 2, owing to iatrogenic medial collateral ligament injury. Conclusion. Long-term studies of both functional and radiological outcomes are needed to determine the indications for fixed- versus mobile-bearing prostheses.
