<p>Total hip arthroplasty (THA) has completely revolutionised the nature in which the arthritic hip is treated, and is considered to be one of the most successful orthopaedic interventions of its generation (1). With over 100 years of operative history, this review examines the progression of the operation from its origins, together with highlighting the materials and techniques that have contributed to its development. Knowledge of its history contributes to a greater understanding of THA, such as the reasons behind selection of prosthetic materials in certain patient groups, while demonstrating the importance of critically analyzing research to continually determine best operative practice. Finally, we describe current areas of research being undertaken to further advance techniques and improve outcomes.</p>

Results of acetabular reconstruction with tantalum constructions were analyzed for 56 patients (25 men and 31 women) aged 35 to 70 years. Primary arthroplasty was performed in 30 and revision intervention in 26 patients. In case of primary total hip arthroplasty the following etiologic factors were considered: posttraumatic acetabulum deformity (21 patients), deficit of acetabular walls resulted from dysplasia (4), femoral head protrusion (5). Evaluation of the defect and selection of tantalum construction were made using defect classification by W.G. Paprosky. Results were assessed by Harris scale at terms 3,6 and 12 months after operation and every year thereafter. Excellent, good and satisfactory results were achieved in 96.8% of cases. The most common complication was the dislocation of hip implant head. It developed in 2 patients after revision arthroplasty and in 1 patient after primary total hip arthroplasty.

SummaryThe behaviour of the contact system was studied in 40 patients with total hip arthroplasty, by measuring plasma prekallikrein, spontaneous kallikrein activity and factor XII. In the literature it had been shown that patients with complications from this operation had decreased prekallikrein and increased kallikrein activity (M. Nakahara. Acta orthop scand 1982; 53: 591-6). In the present study, comprising patients with and without pain and proven loosening of the hip prosthesis, these findings could only partially be confirmed. Patients with a loosened prosthesis had significantly lower prekallikrein (mean 0.78 ± 0.28 U/ml; p <0.01) than patients without problems, but no detectable kallikrein activity in plasma. Patients with pain but no loosening had normal prekallikrein (1.04 ±0 0.26 U/ml) and also no demonstrable kallikrein activity. Factor XII was normal in all patient groups. It is concluded that decreased prekallikrein is limited to patients with a loosened hip prosthesis, with or without pain.

AbstractMeasuring patient satisfaction and surgical outcomes following total joint arthroplasty remains controversial with most tools failing to account for both surgeon and patient satisfaction in regard to outcomes. The purpose of this study was to use “The Forgotten Joint Score” questionnaire to assess clinical outcomes comparing patients who underwent a total hip arthroplasty (THA) with those who underwent a total knee arthroplasty (TKA). We conducted a retrospective review of patients who underwent primary THA or TKA between September 2016 and September 2019 and responded to the Forgotten Joint Score-12 (FJS-12) questionnaire at least at one of three time periods (3, 12, and 21 months), postoperatively. An electronic patient rehabilitation application was used to administer the questionnaire. Collected variables included demographic data (age, gender, race, body mass index [BMI], and smoking status), length of stay (LOS), and FJS-12 scores. t-test and chi-square were used to determine significance. Linear regression was used to account for demographic differences. A p-value of less than 0.05 was considered statistically significant. Of the 2,359 patients included in this study, 1,469 underwent a THA and 890 underwent a TKA. Demographic differences were observed between the two groups with the TKA group being older, with higher BMI, higher American Society of Anesthesiologists scores, and longer LOS. Accounting for the differences in demographic data, THA patients consistently had higher scores at 3 months (53.72 vs. 24.96; p < 0.001), 12 months (66.00 vs. 43.57; p < 0.001), and 21 months (73.45 vs. 47.22; p < 0.001). FJS-12 scores for patients that underwent THA were significantly higher in comparison to TKA patients at 3, 12, and 21 months postoperatively. Increasing patient age led to a marginal increase in FJS-12 score in both cohorts. With higher FJS-12 scores, patients who underwent THA may experience a more positive evolution with their surgery postoperatively than those who had TKA.
