Arthroscopic debridement of the posterior compartment of the knee after total knee arthroplasty is difficult because it is tough to obtain intercondylar notch views. Herein, we performed arthroscopic debridement of the posterior compartment of an infected knee after total knee arthroplasty by using a transseptal portal in a 62-year-old woman with rheumatoid arthritis. Palpation of anatomical la...

PURPOSE The patients expect optimal knee function after Total Knee Arthroplasty. It is necessary to apply appropriate surgical technique and supervised physical therapy. The optimal management of posterior cruciate ligament remains controversial. Both implant designs, i.e., cruciate retaining and posterior substituting, allow the orthopedic surgeon to achieve excellent clinical outcomes, as mea...

Infection is a serious complication after implantation of total knee-prostheses. However, fungal infection is rarely found in periprosthetic joints, and in most reports, the infecting organism is a Candida species. This is a case report of infection after left knee total arthroplasty caused by Malassezia species. The patient is still undergoing antifungal therapy with voriconazole and is still ...

Cruciate-retaining total knee arthroplasty has had high success rates but does not always have optimal functional outcomes. The purpose of this study was to compare 2 polyethylene inserts of varying constraint that were used in a new cruciate-retaining total knee arthroplasty design to determine whether differences were found in clinical or functional outcomes. The use of the newer cruciate-ret...

Total knee arthroplasty has a high success rate. In the interest of enhancing patient outcomes, numerous perioperative interventions have been studied, including preoperative education, preoperative rehabilitation, postoperative inpatient rehabilitation, continuous passive motion, postoperative outpatient rehabilitation, unsupervised in-home exercises, telerehabilitation, and various combinatio...

Ligament balancing is one of the most important surgical techniques for successful total knee arthroplasty. It has traditionally been recommended that medial and lateral as well as flexion and extension gaps are equal. This article reviews the relevant literature and discusses the clinical importance of the aforementioned gaps. Current evidence indicates that achieving medial stability througho...

PURPOSE To identify factors related to knee flexion after total knee arthroplasty in a Chinese population. METHODS Records of 242 total knee arthroplasties were retrospectively reviewed. The parameters evaluated were age, gender, diagnosis, preoperative knee flexion and extension, preoperative flexion arc, tibiofemoral angle, Knee Society knee score and functional score, and implant design. ...

Total knee arthroplasty (TKA) is a satisfactory procedure regarding functional outcome and pain relief. The ever increasing number of total knee arthroplasties and expanding indications have led to a high number of revisions. The principles of revision arthroplasty are to understand the cause of failure, adequate surgical exposure, restoration of limb alignment, achieving appropriate soft tissu...
