BackgroundTo evaluate the midterm clinical outcome, functional outcome, associated complications, and survivorship of high-flexion posterior-stabilized rotating-platform total knee arthroplasty.MethodsWe prospectively analyzed 701 knees in 501 patients, who underwent total knee arthroplasty using high-flexion posterior-stabilized rotating-platform prosthesis. Patients were assessed preoperatively and postoperatively for their ability to kneel, do full squats, do half squats, and sit cross-legged by using a patient-administered questionnaire.ResultsSignificant improvement was seen in patient-reported outcomes at the mean follow-up of 5.5 (range, 5-7) years. Mean flexion achieved postoperatively was 135° (range, 120°-150°) from a mean preoperative flexion of 108.8° (range, 90°-120°). Ninety-five percent of patients were able to sit cross-legged, 90% were able to kneel, 70% were able to perform a half squat, and 20% were able to perform a full squat.ConclusionsPosterior-stabilized, rotating-platform, high-flexion design provides good postoperative flexion, functional outcome, and good midterm survivorship.
Scapholunate dissociation is the most common carpal instability. We are presenting an interesting case of a 24yr old male with scapholunate instability following trauma. Appropriate investigations were done and surgical intervention was done on the same day. The ruptured ligaments were repaired and bony components scapholunate and scaphocapitate were corrected and fixed. Patient was immobilized in plaster for 8 weeks following which active mobilization exercises were started. The functional results were excellent and we have reported them using the mayo wrist score.

INTRODUCTION:The Scapholunate dissociation is an injury to ligaments in the wrist that can lead to loosening of carpal bones. The risk factors are Ulna minus configuration, slope of radial articular surface and Lunotriquetral coalition. The main pathology is rotatory subluxation of the Scaphoid bone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
