Background: Femoroacetabular impingement syndrome (FAI) is a complex, often post-traumatically developing impairment of the hip joint. It is characterized by ambiguous symptomatology, which makes early diagnosis difficult. Aim: The study was conducted to evaluate the applicability of a triaxial gyroscopic sensor in routine practice as an additional indication criterion for operative versus conservative treatment procedures. Methods: Ninety-two patients were included in the experimental retrospective study and 62 completed the examination. All patients signed informed consent. A gyroscopic sensor was placed on the right side of the pelvis above the hip joint and patients walked approximately 15 steps. Data were also evaluated while the patients climbed stairs. A complete clinical examination of the dynamics and physiological movements in the joint was performed. The data measured by the gyroscopic sensor were processed using differential geometry methods and subsequently evaluated using spectral analysis and neural networks. Results: FAI diagnosis using gyroscopic measurement is fast and easy to implement. Our approach to processing the gyroscopic signals used to detect the stage of osteoarthritis and post-traumatic FAI could lead to more accurate detection and capture early in FAI development. Conclusions: The obtained data are easily evaluated, interpretable, and beneficial in the diagnosis of the early stages of FAI. The results of the study show that this approach can lead to more accurate and early detection of osteoarthritis and post-traumatic FAI.

PURPOSE OF THE STUDY Femoroacetabular impingement syndrome is a complex, often post-traumatically developing impairment of the hip joint, characterized by ambiguous symptomatology, which makes early diagnosis diffi cult, especially in the early stages. Experimental retrospective study was carried out to evaluate the usability of a triaxial gyroscopic sensor in routine practice as an additional indication criterion for operative versus conservative treatment procedures. MATERIAL AND METHODS 92 patients were included in the retrospective study, and 62 completed the investigation. All patients signed informed consent. A gyroscopic sensor was placed on the right side of the pelvis above the hip joint, and the patients walked approximately 15 steps. Furthermore, an evaluation of the data during stair climbing and a complete clinical examination of the dynamics and physiological movements in the joint was carried out. Data measured with a gyroscopic sensor were processed using differential geometry methods and then evaluated using spectral analysis and neural networks. The proposed technique of diagnosing FAI using gyroscope measurement is a fast, easy-to-perform method. RESULTS Our approach in processing gyroscopic signals used to detect the stage of arthrosis and post-traumatically developing FAI could lead to more accurate early detection and capture in the early stages. CONCLUSIONS The obtained data are easily evaluated, interpretable and benefi cial in diagnosing the early stages of FAI. The results of the conducted research showed this approach to more accurate early detection of arthrosis and post-traumatically developing FAI.

Osteoarthritis is the most common type of degenerative joint disease and affects millions of people. In this paper, we propose a non-obtrusive and straightforward method to assess the progression of osteoarthritis. In standard medicine praxis, osteoarthritis is observed with X-rays. In this study, we use widely available wearable sensors with gyroscopes to make the observation. Two novel methods are proposed for gyroscope data processing. A small-scale study has shown that these methods can be used to monitor osteoarthritis's progression, and to differentiate between healthy subjects and subjects with femoroacetabular impingement syndrome.

Cíl: Zhodnocení přínosu náhrady předního zkříženého vazu při léčbě jeho parciální ruptury. Materiál a metoda: Do retrospektivní studie bylo zahrnuto 72 pacientů s artroskopicky verifikovanou parciální rupturou předního zkříženého vazu od 1/2010 do 12/2012. Z tohoto souboru 40 pacientů podstoupilo náhradu vazu. Sledované parametry byly objektivní nestabilita kloubu, časový interval k plné fyzické aktivitě a subjektivně hodnocená bolest a nestabilita kloubu. Sběr dat byl prováděn retrospektivně z ambulantních záznamů. Vyhodnocení bylo provedeno vzájemným porovnáním výsledků obou skupin. Výsledky: Při vyšetření ve třetím měsíci pociťovali subjektivní nestabilitu tři operovaní pacienti a devět neoperovaných při běžné zátěži. V šestém měsíci udali subjektivní nestabilitu dva operovaní pacienti a devět konzervativně léčených při běžné zátěži. Při sportovní zátěži jeden operovaný a 10 neoperovaných. Ve 12. měsíci pociťoval nestabilitu při běžné zátěži jeden operovaný a devět neoperovaných. Při sportovní aktivitě nepociťoval subjektivní nestabilitu žádný operovaný pacient, konzervativně léčených ji udávalo 14 pa cientů. V hodnocení subjektivní bolesti při běžné zátěži ve třetím měsíci bylo bez obtíží 16 operovaných a 11 neoperovaných pacientů. V šestém měsíci při sportovní aktivitě bylo bez obtíží 10 operovaných a tři konzervativně léčení pacienti, při běžné zátěži 14 operovaných a 10 neoperovaných pacientů. Ve 12. měsíci u operovaných pacientů bylo při běžné zátěži bez obtíží devět, při sportovních aktivitách 11. U neoperované skupiny bylo devět pacientů bez obtíží u běžné aktivity a tři při sportu. Závěr: Pacienti po nahrazení předního zkříženého vazu měli menší obtíže charakteru klidových i pozátěžových bolestí kloubu. Tato skutečnost platila v průběhu celého monitorovaného období a také u nich pro běhl plynulejší návrat k původním sportovním aktivitám.
Aim of the study: Evaluation of anterior cruciate ligament replacement as therapy option in case of partial rupture of this ligament. Material and methods: 72 patients with arthroscopically verified partial rupture of the anterior cruciate ligament (ACL) between 1/2010 and 12/2012 were included in the retrospective study. From this group 40 patients had undergone ACL replacement surgery. Parameters monitored were objective instability of joint, the time interval to full physicall activity and subjectively felt pain and joint instability. Data collection was carried out retrospectively from the out-patient records. The results oft he two groups were compared. Results: During examination in the third month, three operated and 9 non-operated patients felt instability during normal load. In the 6th month two operated and 9 conservatively treated patients complained of instability at normal load, and 1 operated and 10 non-operated during sports load. In the 12th month during normal load 1 of the operated and 9 of the non-operated patients reported to feel instability. Non of the operatred patients felt subjective instability during the sports activity, compared to 14 conservatively treated patients who complained of instability. In the subjective evaluation of pain during normal loads in the 3rd month, 16 operated and 11 non-ope rated patients haven’t experienced diffi culties. In the sixth month during sports 10 operated and 3 conservatively treated patients were without diffi culties and under normal load 14 operated and 10 non-operated patients did not complain. After 12 months in the operated group 9 during normal activities and 11 during sports were without complaints. In the non-operated group, 9 patients with normal activity and 3 patients during sports activities had no complaints. Conclusion: Patients who underwent ACL replacement for partial ACL lesion had less problems during normal and sport activities. This was true fort the whole follow-up period. Their return tot he previous sport activities was more smooth.
