Abstract
Total hip arthroplasty is one of the most commonly performed Orthopaedic procedure in the twenty-first century as it has been shown that THA provides excellent pain relief and improved quality of life for patients with painful arthritis of the hip.
The national trends indicate that the prevalence of diabetes mellitus (DM) is increasing rapidly and the number of patients with diabetes and osteoarthritis seeking an arthroplasty also can be expected to increase with time
Diabetes contributes to poor Orthopaedic surgical outcomes including infection, increased pain and stiffness, decreased joint function, and reduction of implant survivorship requiring subsequent revision surgery
Common indications for THA are primary osteoarthritis hip and secondary osteoarthritis due to avascular necrosis of femoral head, fracture acetabulum and fracture femoral neck.
The aim of this study was to compare the outcome of primary total hip arthroplasty in diabetic and non-diabetic group.
This is a prospective study included forty patients divided into two groups; a diabetic group included twenty patients and a non-diabetic group included twenty patients.
Significant difference was found between pre-operative and post-operative Harris hip score in the two groups (P<0.001) showing the improvement of the functional outcome after the procedure.
The results showed no difference between the two groups as for functional outcome, higher infection rate was found among diabetic patients, though it was statistically insignificant.
The diabetic group had significantly higher hospital stay (p=0.047), increased total cost and increased need for post-operative blood transfusion (p=0.004) in comparison to the non-diabetic group.
This study also confirmed the negative impact of infection on the post-operative functional outcome as the infection was associated with poorer outcome (p=0.010) in addition to the effect of the weight on the functional outcome as increased body weight was associated with poorer outcome (p=0.005).
In general the results of our study were comparable to the results reported by other studies. Most of the patients in our study achieved satisfactory outcome and the number of patients who required revision surgery was very low.
