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.

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.

Background: This prospective clinical study was performed to compare the clinical outcomes between patients with cruciate-retaining (CR) and cruciate-substituting (CS) total knee arthroplasty (TKA). Methods: from July 2018 to June 2019, 52 patients (32 females and 20 males) with a total of 70 knees with a mean age of 61.11 years (range, 46 to 78 years) were enrolled in this study. Patients were randomly divided into two groups including group A (Cruciate-Retaining Total Knee Arthroplasty (CR-TKA) underwent 35 CR TKA, and group B (Cruciate-Substituting Total Knee Arthroplasty (CS-TKA) underwent 35 CS total knee Arthroplasty. The evaluation parameters included knee scores, pain score, functional scores, radiographs of the knees and ROM (Range of motion). Regular follow up done at 4 weeks, 12weeks and then every 6 months. All data were collected and analyzed with the help of suitable statistical parameters. Results: Both designs give equal and good results. We preferred CR Knees in relatively young patients and patients with smaller knees as its bone conserving implant and CS knees in patients with Inflammatory arthritis, patient with severe Varus or flexion deformity, when tibia cut is more than 10 mm and when intra-operatively findings suggestive of non-functional posterior Cruciate ligament. However, in our short term randomized interventional study Posterior Cruciate substitution Total Knee Arthroplasty had a marginally better outcome than the posterior Cruciate retaining in terms of range of motion but it needs a long-term analysis. Key words: Cruciate substitution Total Knee Arthroplasty, Cruciate-Retaining Total Knee Arthroplasty, Knee scores, Pain score

Medial collateral ligament injury during primary total knee arthroplasty is a recognised complication potentially resulting in valgus instability, suboptimal patient outcomes and a higher rate of revision or reoperation. Options for management include primary repair with or without augmentation, reconstruction or immediate conversion to prosthesis with greater constraint, in conjunction with various postoperative rehabilitation protocols. Inconsistent recommendations throughout the orthopaedic literature have made the approach to managing this complication problematic. The objective of this study was to review the available literature to date comparing intraoperative and postoperative management options for primary total knee arthroplasty complicated by recognised injury to the medial collateral ligament. This systematic literature review was prospectively registered with PROSPERO (#CRD42014008866) and performed in accordance with PRISMA guidelines including a PRISMA flow diagram. Five articles satisfied the inclusion criteria. Each was a retrospective, observational cohort or case series with small numbers reported, inconsistent methodology and incompletely reported outcomes. Four of the five studies managing medial collateral ligament injury during total knee arthroplasty (47/84 patients) with direct repair with or without autograft augmentation reported good outcomes with no revision or reoperation required for symptomatic instability over a follow-up period of 16 months to almost 8 years. The fifth study with a follow-up to 10 years and a high rate of conversion to unlinked semi constrained total knee arthroplasty implant (30/37 patients) reported a greater incidence of revision due to instability, in patients in whom the medial collateral ligament injury was directly repaired without added constraint. Overall balance of evidence is in favour of satisfactory outcomes without symptomatic instability following direct repair with or without augmentation of an medial collateral ligament injury recognised intraoperatively during total knee arthroplasty. An implant with greater constraint may have reduced longevity in younger, more active patients through aseptic loosening. In elderly or less mobile patients, and in situations where the medial collateral ligament repair is deemed poor quality or incomplete, an implant with greater constraint would seem prudent. In patients where direct repair with or without augmentation was used, a period of 4-6 weeks of unrestricted rehabilitation in a hinged knee brace should be followed.
