Comparison of Hip Functional Value and Quality of Life Between Cemented and Uncemented Hip Arthroplasty Patients

Introduction. Hip arthroplasty is aimed to reduce pain and restore hip joint function. Until now, the most optimal method for fixation in Hip Arthroplasty is controversial. The purpose of this study was to analyze the comparison of hip functional value and quality of life between cemented and uncemented hip arthroplasty patients. Methods. This study used cross sectional design. Data were collected via medical record and SF-12 questionnaire and Oxford hip score in patients who have received hip arthroplasty at general hospital Dr. Moh. Hoesin Palembang. Results: There were 43 cases found, consisting of 28 cemented cases and 15 uncemented cases. The average age was 60.42 ± 19.44 years with an age range of 24-88 years. 20 subjects (46.4%) and 23 subjects (53.5%) women. The most preoperative diagnosis was trauma / fracture (69.8%), followed by osteoarthritis (16.3%), osteonecrosis (4.7%). Previous normality tests have been done with the Sapiro-Wilk test and homogeneity test. A comparison of hip functional values ​​between cemented and uncemented hip arthroplasty patients had a value of p = 0.76 (p <0.05) meaning there was no significant difference. Comparison of quality of life between cemented and uncemented hip arthroplasty patients has a value of p = 0.592 (p <0.05) which also means there is no significant difference. Conclusion: There was no difference in pelvic functional value and quality of life between cemented and uncemented hip arthroplasty patients.

Hydroxyapatite Hip Arthroplasty in Osteoporotic Bone: A Study in Female Patients Over the Age of Sixty

Uncemented hip arthroplasty is gaining interest. However, it is alleged that uncemented hip implants fail in osteoporotic bone because of early loosening and a higher incidence of periprosthetic fractures. Will Hydroxyapatite Ceramic Coated Hips (HAC) bond on to the osteoporotic bone and continue to function well in this vulnerable group of patients? Post-menopausal women are prone to develop osteoporosis. They are seen too frequently with wrist, hip and spinal crush fractures following minor low impact injuries. These ladies also contribute to the cohort of patents requiring hip arthroplasty for all the usual diagnoses including sub capital fractures. This is a study of HAC hip arthroplasty in female patients over the age of sixty which includes women with osteoporosis.

Unrestricted Weight Bearing and Intensive Physiotherapy after Uncemented Total Hip Arthroplasty

Background and Aims: The effectiveness of partial weightbearing after hip surgery has been questioned as well as the need of intensive physiotherapy. Material and Methods: 36 patients (average age 54.4, 19 women) operated with uncemented hip arthroplasty were randomized either to unrestricted weightbearing (UWB) combined with intensive physiotherapy or to partial weightbearing (PWB) for 3 months combined with a short self-training program. The load during walking and the muscle strength (MS) in abduction was measured preoperative and subsequent up to 12 months. Results: The average peak load on the operated leg at one week was 39.0 kg for the UWB and 25.8 for the PWB group (P = 0.009) while at three months 70.0 and 31.7 (P = 0.001) respectively. At 6 and 12 months there were no differences between the groups. The muscle strength increased in both groups up to six months but there were no differences between the groups. Conclusions: Even though patients applied more load than the recommended 15 kg most patients were able to comply with partial weightbearing fairly well. The effect of intensive physiotherapy on the muscle strength after hip arthroplasty is questionable.
