From 2004 to 2014 there were conducted more than 400 operations with the use of ceramic- polyethylene prostheses in the Hospital №13 (clinical base of the Department of Traumatology and Orthopedics of Peoples’ Friendship University of Russia). In any case there were no signs of aseptic loosening of prosthesis components. Nowadays the use of low friction ceramic-polyethylene friction pair in hip arthroplasty is widespread for most patients with hip joint pathology in all age groups.

A comparative analysis of the clinical, functional and radiological results of total hip arthroplasty (THA) in pts with primary osteoarthritis (PA) was carried out. The aim was to improve the results of THA in pts with degenerative diseases of the hip joint based on the choice of the optimal type of components fixation. The study included 125 patients (68 women, 57 men) with primary coxarthritis who underwent 125 operations of unilateral THA. All pts were divided into two groups depending on the type of components fixation. Group I (N = 63; average age 69.8 ± 3.1; from 34 to 75 years) included pts with cementless fixation (DePuy, Zimmer, titanium cups, titanium stems such as Corail and Zweymuller), in group II (N = 62; average age 67.2 ± 2.7; from 44 to 87 years) — with cement fixation (Zimmer, Smith & Nephew — low-profile Muller cup, Muller stem). Metal-polyethylene friction pair and head size 32 mm were used in all cases. Evaluation of the results was carried out on 2, 6 months, 1, 5, 10 years after the operation and included: functional state assessment (Harris Hip Score), radiographs analysis, as well as the frequency of complications and revision interventions. There were no significant differences in the incidence of deep periprosthetic infection, thromboembolic complications, hematomas, paraarticular ossifications, aseptic loosening, dislocations and revision interventions. There was faster positive dynamics in the early period (up to 6 months) when using cemented THA. Subsequently all the indicators were comparable in both groups. Osteolysis at the border of implant fixation was recorded in two cases in group I and in 11 cases in group II (p < 0,05). In group I, eight periprosthetic intraoperative fractures of the proximal hip were recorded; in group II, this complication was obtained in one pt (p < 0.05). Stress-shielding syndrome was detected in six pts from group I. This complication was not detected in group II (p < 0.05). Thus, both methods are comparable in results and can be equally applicable for the surgical treatment of patients with primary osteoarthritis, which can significantly expand the possibilities of specialized medical care and effective rehabilitation of this category of patients.

Kallikrein Activity

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.
