ObjectivesThe study evaluated the professional activity of patients after a total cementless hip replacement surgery performed at the age of ≤30 years.Material and MethodsThe study group comprised 87 patients, with 95 total cementless hip replacements. The mean age was 25.7 years. The youngest patient was 17 years old, and the oldest 30 years old. The mean length of observation was 20.1 years, ranging 5–33 years. All patients underwent clinical and radiological evaluations before the surgery, and again in the third, sixth and twelfth months after the surgery. Further follow-up visits were performed every year. The tests were scored according to the Merle d’Aubigné and Postel (MAP) classification, as recommended by the Polish Society of Orthopaedics and Traumatology. Postoperative radiographs were used to assess the position of the endoprosthesis, and the degree of implant healing in the bone tissue. The data was subjected to statistical analysis.ResultsOf the surveyed group, 67 patients were professionally active before the surgery: 34 were white-collar workers, 29 manual workers, and 4 students or school pupils. The remaining 20 had not worked for many years, and were receiving sickness or disability benefits. An excellent result, according to the Kellgren-Lawrence classification, was noted in 22 cases, a good result in 42 cases, and a satisfactory result in 6 cases. In 25 cases, a poor result was observed. All of the patients professionally active before the surgery returned to work following the procedure. A further analysis found that 15 previously-unemployed patients commenced employment following the procedure. The mean length of the sick leave was 196.2 days, and rehabilitation payments were granted in 5 cases.ConclusionsTotal cementless hip replacement is a valuable method of treating osteoarthritis in young patients. All of the patients who worked before the surgery returned to work in the same position and on the same employment conditions. Most of the previously-unemployed patients commenced employment following the procedure.

Wstęp. Coraz większą uwagę w praktyce klinicznej zwraca się na ocenę sprawności sensomotorycznej jako istotnego czynnika determinującego powrót funkcji. Celami niniejszej pracy były: ocena wpływu uszkodzeń związanych z zaawansowaną gonartrozą na zmianę czucia głębokiego i kontroli sensomotorycznej stawu kolanowego, porównanie wyników uzyskanych we własnym teście kontroli sensomotorycznej z obiektywnymi metodami oceny czucia głębokiego, analiza zależności pomię- dzy poziomem czucia głębokiego i sprawnością układu sensomotorycznego a pomiarami stosowanymi w praktyce klinicznej. Materiał i metody. Ocenie poddano grupę osób zdrowych (grupa kontrolna, n=74), grupę pacjentów z chorobą zwyrodnieniową IV st. (grupa 1, n=67) oraz pacjentów po endoprotezoplastyce stawu kolanowego (grupa 2, n=62). Badanych oceniano z wykorzystaniem autorskiego Testu Kontroli Sensomotorycznej (TKS) oraz testu czucia pozycji stawu (JPS). Analizowano również wyniki uzyskane w skalach HSS Knee Score i Stafflstein-Score.Wyniki. W ocenie za pomocą TKS i JPS grupa kontrolna uzyskała wyniki na poziomie odpowiednio 4,9 pkt i 3,9°, natomiast grupa 2 3,7 pkt i 6,7° (p<0,005). W grupie 1 uzyskano 3,2 pkt w TKS, natomiast w JPS 8,2° w kończynie zdrowej i 10,2° w kończynie chorej. Wyniki tej grupy były istotnie gorsze niż grupy kontrolnej oraz grupy 2 (p<0,005). Wnioski. 1. Prezentowany własny test oceniający sprawność sensomotoryczną stawu kolanowego wydaje się obiektywnym i kompleksowym sposobem oceny sprawności kontroli sensomotorycznej stawu kolanowego u pacjentów z gonartrozą i po endoprotezoplastyce stawu kolanowego. 2. Wskazane są dalsze badania z wykorzystaniem autorskiego testu kontroli sensomotorycznej obejmujące próbę jego obiektywizacji z wykorzystaniem specjalistycznych narzędzi pomiarowych.

Introduction. The importance of sensorimotor control assessment as a crucial factor determining functional recovery is being increasingly appreciated in clinical practice. The aim of this study was to assess the inflence of damage associated with severe gonarthrosis on changes in proprioception and sensorimotor control of the knee, compare the results of a new sensorimotor control test developed by the authors with objective methods of proprioception assessment, and analyse the relation between the level of proprioception and sensorimotor system function and the measurements used in clinical practice. Material and methods. We studied a group of healthy persons (control group, n=74), patients with stage 4 knee osteoarthritis (group 1, n=67), and patients after total knee arthroplasty (group 2, n=62). The participants were assessed with a new sensorimotor control test (TKS) and a joint position sense test (JPS). Moreover, we analysed the patients’HSS knee scores and Stafflstein scores.results. In the Control Group, mean TKS and JPS test scores were 4.9 pts and 3.9°, respectively, while the respective results in group 2 were 3.7 pts and 6.7° (p<0.005). In group 1, the TKS score was 3.2 pts and the JPS test result was 8.2° in the unaffcted limb and 10.2° in the affcted limb. The results of this group were signifiantly worse than the scores achieved in the control group and group 2 (p<0.005). conclusions. 1. The new knee sensorimotor control test developed by the present authors appears to provide an objective and comprehensive method to evaluate sensorimotor control of the knee in patients with gonarthrosis and after total knee replacement. 2. Further studies of the new test are advised, including an objective evaluation of the test utilising specialised measuring tools.
