BACKGROUND Patellofemoral joint replacement is a successful treatment option for isolated patellofemoral osteoarthritis. However, results of later conversion to total knee replacement may be compromised by periprosthetic bone loss. Previous clinical studies have demonstrated a decrease in distal femoral bone mineral density after patellofemoral joint replacement. It is unclear whether this is d...

background osteoarthritis (oa) is a multifactorial, disabling and degenerative disease that worsens with age and affects patient’s health-related quality of life (hrqol). objectives the current study aimed to assess if age and comorbidities have an influence on knee oa and knee replacement outcome before and after the surgery. methods a quasi-experimental intervention study was conducted on a s...

The results of primary total knee replacement performed on a group of haemophiliac patients in a single institution by the same surgeon using the same surgical technique and prosthesis are reported. A total of 35 primary replacements in 30 patients were carried out between 1996 and 2005 and were reviewed retrospectively. The mean age of the patients was 31 years (24 to 42) and the mean follow-u...

Surgeries for total knee replacement (TKR) are increasing and in this context there is a need to develop new protocols for management and use of blood transfusion therapy. Autologous blood reduces the need for allogeneic blood transfusion and the aim of the present study was to verify the safety and the clinical efficacy. An observational retrospective study has been conducted on 124 patients, ...

Chemical prophylaxis is known to reduce the venographic prevalence of deep-vein thrombosis (DVT) after total knee replacement (TKR), but it is uncertain whether this affects the incidence of symptoms. Further analysis depends on the basic epidemiology of thromboembolic symptoms. We therefore studied the pattern of such symptoms in a consecutive series of 1000 patients with primary TKR, with par...

EditorÐRahman and colleagues 1 make the interesting observation that obstructed breathing in post-operative patients was more common when they were awake than when they were asleep. This seems to contradict our study 2 where we found obstructed breathing postoperatively only when patients were asleep. There were important differences between the two studies. We 2 divided 32 patients into two eq...

PURPOSE OF THE STUDY The objective of the study was to find out to what extent anatomical changes due to high osteotomy of the tibia affect knee function after total knee arthroplasty. MATERIAL Of the patients with knee osteoarthritis treated by cemented total PFC prostheses in 1995, two groups were selected. Group I consisted of 50 patients who had knee replacement without previous tibial os...

OBJECTIVES To determine the infection rate and identify the risk factors of primary total knee replacement in a general hospital and discuss possible preventive measure. DESIGN Retrospective study. SETTING Regional hospital, Hong Kong. PATIENTS All cases of primary total knee replacement performed between the period July 1997 and June 2006 were reviewed. MAIN OUTCOME MEASURES Infection ...

The intramedullary alignment guides used in total knee replacement disrupt the intramedullary vessels, resulting in greater postoperative blood loss. The use of an autologous bone plug to seal the intramedullary femoral canal has been shown to be effective in reducing postoperative bleeding. The authors present a simple technique to create a bone plug from the anterior chamfer femoral cut to pe...

BACKGROUND AND PURPOSE It is unclear whether mobile-bearing (MB) total knee arthroplasties reduce the risk of tibial component loosening compared to fixed-bearing (FB) designs. This randomized study investigated implant migration, periprosthetic bone mineral density (BMD), and patient-reported outcomes (Oxford knee score)-all at 2 years-for the P.F.C. Sigma Cruciate Retaining total knee arthrop...
