Navigated total knee replacements (TKR) have shown better knee function and quality of life. It also reduces revision rates. The aim of our study is to evaluate short to mid-term clinico-radiological and functional results, survival rate and complications of Gradius knee prosthesis implanted using computer navigation.

We retrospectively reviewed 120 Gradius knee prosthesis, implanted in 68 patients (52 bilateral TKR and 16 unilateral TKR) and followed from Jan 2015 till Jan 2020. Pre-operative & post-operative radiographs, knee society scores (KSS), range of motion (ROM), deformity assessment and gait video recordings were done for all patients.

The mean follow-up was 3.8years (minimum 2-5years).The mean ROM was 2° (0-10) extension to 135° (128°-138°) flexion. The KSS pain score improved from mean of 38.3 (range 26-44) to 90.4 (mean 88-92). The KSS functional score improved from 36.2 (range 28-39) to 92.6 (range 86-94). All patients had excellent to good function during successive follow-ups. The coronal alignment improved from 8° varus to 0.3° varus. Sagittal alignment was corrected from 8° (4°-18°) preoperatively to 2° (0°-8°) postoperatively.

At mid-term our series outlines the better functional and radiological results of Gradius knee prosthesis using navigation as a tool. We recommend a prospective randomized controlled trials comparing navigated versus non-navigated for Gradius knee prosthesis with long-term follow-up.

Many designs of TKR have been developed to optimize the kinematics and improve satisfaction, including the 'medial rotating' philosophy. The purpose of this study is to report the mid-term clinical outcome of MRK knees and evaluate whether resurfacing the patella makes any difference in outcome.

A retrospective analysis was done of 104 MRK total knee replacement done between 2008 and 2017. Patients were called for a review for evaluation of OKS, Baldini and Feller scores. Demographics of the patients, clinical outcome, complications were assessed.

62 had patellar resurfacing. Mean follow-up was 74.45months in non- resurfaced and 54.93months in resurfaced group. Mean flexion range in both groups at final follow-up was 101.45. Median OKS at follow-up was 36 (12-47) in non-resurfaced and 37 (9-48) in resurfaced group. Patella scores were better in resurfaced group-Baldini score median (range) was 90 (25-100) in non-resurfaced v/s 100 (30-100) in resurfaced, Feller score median (range) was 25 (12-30) in non-resurfaced v/s 28 (10-30) (

0.042) in resurfaced. The patellofemoral component of the OKS (Q5 + Q7 + Q12) median showed an improvement from 3 (1-11) to 6.5 (3-11) in non-resurfaced and from 3 (0-12) to 8 (2-12) (

0.039) in resurfaced group. There were five complications overall (4.8%).

These results show a satisfactory outcome at mid-term follow-up. We found a statistically significant difference in Feller score and in the patellofemoral component of OKS between the groups of MRK knee suggesting specific benefits of patellar resurfacing with this implant.

The number of joint replacements in India is set to grow at thehighest rate in the world from 2020 to 2026. It is high time for India to have anefficient and credible registry to help curtail the clinical impact of implant failure at a very early stage by prompt reporting.

Indian Joint Registry has been established by ISHKS with new data forms for reporting. These new detailed forms record, in addition to previous form, component-wise details of implants. Additional useful features include Linking with unique ID like PAN or Aadhaar, thromboprophylaxis, untoward intra-operative event, IJR consent and type of anaesthesia.

There were712 registered surgeons in IJR databasetill June 2020. Total TKRs being reported to registry increased from 1019 in 2006 to 27,000 in 2019. Majority of the patients (98.5%) were diagnosed with osteoarthritis knee. Company-wise distribution unveils that Johnson & Johnson DePuy represents the highest implant usage at over 37%. There has been increased utilisation of uncemented THR over cemented THR from 2006 to 2019. Dual-mobility THRs have gained ground as surgeon preference for the choice of implant.

Effective use of quality registries can lead to better health outcomes at a lower cost for the society. An effective, responsive and sustainable registry in India offers many benefits and should be considered as a key objective. Making the registry function in India successfully will undoubtedly require multi-pronged efforts, but can deliver many benefits both to the patient and to the nation as a whole.

To analyse the incidence of additional soft tissue releases with the lateral parapatellar approach, and the clinical and radiological outcomes of total knee arthroplasties performed using the lateral parapatellar approach for valgus arthritic knees. A review of the existing literature on valgus arthritic knees undergoing knee replacement was performed and our results compared.

This is a prospective cohort study of 50 patients operated by this approach. Operation and clinical records were assessed to determine the number and sequence of soft tissue releases. Functional outcome was measured using the Oxford Knee Score. Radiological assessment included measurement of alignment and implant positioning.

46 patients included. Mean follow-up of 4years. Additional lateral releases were performed in 11 (24%) cases. Mean valgus alignment corrected from 13.1 degrees pre-operatively to 5.7 degrees post-operatively. Oxford Knee Score improved from a mean pre-operative score of 11.9 to a mean post-operative score of 38.3 at final follow-up. Radiographs revealed lateralisation of the tibial component in 4 patients. No immediate or late post-operative wound complications, late instabilities or revisions were observed.

Lateral parapatellar approach is highly effective in correcting the valgus deformity with a low incidence of additional soft tissue releases. Medium-term results indicate an excellent functional outcome with no complications.

With the advances of modern medicine and technology there has been an increase of indications of shoulder reconstruction techniques and shoulder arthroplasty. Consequently, the number of complications and failures have increased in parallel. Not negligible number of cases are driven to an end-stage situation where salvage procedures, such as glenohumeral arthrodesis (GHA) and shoulder resection arthroplasty (SRA), are the only remaining solution.

The current literature on glenohumeral arthrodesis and shoulder resection arthroplasty was reviewed to determine the indications, surgical technique, complications and outcomes. The electronic search was conducted using the MEDLINE and EMBASE databases and the strategies used were "glenohumeral arthrodesis", "glenohumeral fusion", "shoulder arthrodesis" and "shoulder resection arthroplasty".

Indications for glenohumeral arthrodesis (GHA) include brachial plexus injury, tumor resections, chronic infection, failed prosthetic arthroplasty, persistent refractory inx shoulder pathology.

Despite GHA and SRA having negative connotations, in selected patients, these procedures can diminish pain, resolve persistent infections and provide an acceptable shoulder function. Hence, they should be retained as part of the treatment algorithm for complex shoulder pathology.

Ideal surgical positioning and placement of implants during arthroplasty are crucial for long-term survival and optimal functional outcomes. Inadequate bone stock or defects, and anatomical variations can influence the outcomes. Three-dimensional printing (3DP) is an evolving technology that could provide patient-specific instrumentation and implants for arthroplasty, taking into account anatomical variations and defects. However, its application in this field is still not adequately studied and described. The present review was conceptualised to assess the practicality, the pros and cons and the current status of usage of 3DP in the field of hip and knee arthroplasties and joint reconstruction surgeries.

A PubMed database search was conducted and a total number of 135 hits were obtained, out of which only 30 articles were relevant. These 30 studies were assessed to obtain the qualitative evidence of the applicability and the current status of 3D printing in arthroplasty.

Currently, 3DP is used for preoperative planning with 3D models, to assess bone defects and anatomy, to determine the appropriate cuts and to develop patient-specific instrumentation and implants (cages, liners, tibial base plates, femoral stem). Its models can be used for teaching and training young surgeons, as well as patient education regarding the surgical complexities. The outcomes of using customised instrumentations and implants have been promising and 3D printing can evolve into routine practice in the years to come.

3D printing in arthroplasty is an evolving field with promising results; however, current evidence is insufficient to determine significant advantages that can be termed cost effective and readily available.
