AbstractDemographic changes have resulted in an increase in the number of older patients diagnosed with degenerative joint disease. Developments in the field of joint arthroplasty allow a broader population to improve their lifestyles. An increased demand for knee arthroplasty has led to a rise in operations performed worldwide. Although there has been a constant propagation of technology and an increase in medical staffing at a professional level, many patients still encounter complications. Though rare, these factors may lead to life-threatening scenarios and a devastating effect on the success of the operation. One such rare complication includes periprosthetic fractures around the knee, a complex injury which requires a cautious and experienced approach. In this review, we analyze the prevalence, risk factors and classification, investigation and treatment options for periprosthetic fractures with total knee arthroplasty.

Introduction: Total knee arthroplasty represents a major advance in the treatment of degenerative joint disease. It provides excellent restoration of joint function and pain relief. The primary indication for total knee arthroplasty is to relieve pain caused by severe arthritis, with or without significant deformity. This study is to assess psychological impact pre and post arthroplasty. Materials and method: A prospective study on a cohort of patients from June 2010 untill December 2011 admitted to Hospital Tengku Ampuan Afzan for total knee replacement. Cognition tested using DASS21 (Depression Anxiety Stress Scales 21). Questionnaires were distributed 2 days before the operation and 6 months after the operation during clinic follow up. Verbal consent acquired from the patients before giving the questionnaires. Sets of questions are self-administered. Results: As for DASS 21 analysis, pre and post-operative depression was 19.91±4.92 and 6.42±3.64 respectively. Moderate depression became normal post-operative. Questions regarding positive feeling, courage to do things, hope, self- appreciation and the meaning of life were asked pre and post operatively. Pre-operative anxiety was 19.49±4.92 and post-operative anxieties at 6 months were 6.42±3.64. Severe anxiety became normal after 6 months. Patients were asked about mouth dryness, difficulty in breathing on resting, tremor, panicking and unnecessary anxiety pre and post operatively. Post-operative stress improved tremendously from 22.47±4.27 down to 8.56±3.42. Conclusion: As a conclusion, total knee arthroplasty is well accepted in Malaysia. It improves patients’ social and emotional well-being. With the current advancement in total knee arthroplasty, surgeons not only looking into the post-operative physical function, they also look after the cognitive function as the outcome measure of total knee arthroplasty.

AbstractAs with most new surgical technologies, there is an associated learning curve with robotic-assisted total knee arthroplasty (TKA) before surgeons can expect ease of use to be similar to that of manual cases. Therefore, the purpose of this study was to (1) assess robotic-assisted versus manual operative times of two joint reconstructive surgeons separately as well as (2) find an overall learning curve. A total of 240 robotic-assisted TKAs performed by two board-certified surgeons were analyzed. The cases were sequentially grouped into 20 cases and a learning curve was created based on mean operative times. For each surgeon, mean operative times for their first 20 and last 20 robotic-assisted cases were compared with 20 randomly selected manual cases performed by that surgeon as controls prior to the initiation of the robotic-assisted cases. Each of the surgeons first 20 robotic assisted, last 20 robotic assisted, and 20 controls were then combined to create 3 cohorts of 40 cases for analysis. Surgeon 1: First and last robotic cohort operative times were 81 and 70 minutes (p < 0.05). Mean operative times for the first 20 robotic-assisted cases and manual cases were 81 versus 68 minutes (p < 0.05). Mean operative times for the last 20 robotic-assisted cases and manual cases were 70 versus 68 minutes (p > 0.05). Surgeon 2: First and last robotic cohort operative times were 117 and 98 minutes (p < 0.05). Mean operative times for the first 20 robotic-assisted cases and manual cases were 117 versus 95 (p < 0.05). Mean operative times for the last 20 robotic-cohort cases and manual cases were 98 versus 95 (p > 0.05). A similar trend occurred when the times of two surgeons were combined. The data from this study effectively create a learning curve for the use of robotic-assisted TKA. As both surgeons completed their total cases numbers within similar time frames, these data imply that within a few months, a board-certified orthopaedic joint arthroplasty surgeon should be able to adequately perform robotic TKA without adding any operative times.
