The study describes the cardiorespiratory and statistics performance of ice hockey players during the season of 2020 after the COVID-19 lockdown’. Eight elite Czech male players (4 non-COVID-19 and 4 COVID-19 groups) were evaluated before and after the competition season. Players performed a cardiorespiratory exercise test and the maximal oxygen consumption, ventilatory threshold, respiratory compensation point, maximal heart rate and test time were measured. The number of matches, goals and plus/minus statistics were retained. No significant differences between groups before and after the season for all cardiorespiratory responses were found, and the no-COVID-19 group played more games. The conclusion highlights that the cardiorespiratory performance place all players (with and without COVID-19 history) in similar conditions to be prepared for the next season. Due to a wide variation among players’ statistics, based on plus/minus parameters, cannot be established that the 2020 season impaired the players’ statistics.
Východiska: Zvyšující se kvalita onkologické léčby a včasný záchyt nádorů má vliv na počty pacientů, kteří přežijí onkologickou léčbu. Pozornost lékařů, ale i vědců se proto stále více zaměřuje na následky léčby než jen na léčbu samotnou. Jednou z možností, jak pozitivně ovlivnit nežádoucí účinky onkologické léčby, se jeví pohybová aktivita. Metody: Do našeho výzkumu se zapojilo 18 žen po prodělané léčbě karcinomu prsu, 17 z nich výzkum dokončilo (průměrné hodnoty testovaného souboru: 55,9 let, 165,1 cm, 76,9 kg, body mass index (BMI) 28,3). Pacientky, které podepsaly informovaný souhlas, byly rozděleny do tří skupin (SAPA = cvičení pod dohledem 3× týdně, HAPA = cvičení doma 3× týdně a kontrolní skupina bez pohybové aktivity). Celá intervence trvala 12 týdnů a samotná cvičební jednotka obsahovala aerobně-rezistentní složku a jógovou složku. Během cvičení byla u pacientek sledována srdeční frekvence pomocí hrudních pásů a sporttesterů. Pro zhodnocení změn kvality života jsme použili spiroergometrii (VO2peak), bioelektrickou impedanci a spektrální analýzu variability srdeční frekvence. Výsledky: VO2peak se u cvičících skupin zvýšilo v průměru o 5 ml/min/kg (p = 0,082). Podobný trend byl patrný i u některých hodnot složení těla (kosterní svalovina: p = 0,005; beztuková tělesná hmota: p = 0,006). Statistické významnosti nedosáhly hodnoty změn BMI (p = 0,131) a autonomního nervového systému (p = 0,513; p = 0,585). Závěr: I přesto, že naše výsledky naznačují pozitivní trend v ovlivnění kvality života pacientek po léčbě karcinomu prsu pomocí cvičení, je potřeba podobný výzkum zopakovat na větším zkoumaném souboru, abychom mohli naše výsledky potvrdit.
Background: The increasing quality of cancer treatment and early detection of tumors have an impact on the number of patients who survive cancer treatment. Therefore, the attention of physicians as well as scientists is increasingly focused on the consequences of the treatment than just on the treatment itself. One of the ways to positively influence the side effects of oncological treatment seems to be physical activity. Methods: In our research, there were involved 18 women after breast cancer treatment, 17 completed the research (average values of the tested group: 55.9 years, 165.1 cm, 76.9 kg, body mass index (BMI) 28.3). The patients who signed informed consent were divided into 3 groups (SAPA = supervised exercises 3times a week, HAPA = home exercises 3times a week, and a control group without exercises). The whole intervention lasted 12 weeks and the exercise unit itself contained an aerobic-resistant component and a yoga component. During the exercise, the patients‘ heart rate was monitored using a chest belt and sports testers. We used spiroergometry (peak oxygen uptake – VO2peak), bioelectric impedance, and spectral analysis of the heart rate variability to evaluate changes in the quality of life. Results: VO2peak increased in training groups by an average of 5 ml/min/kg (P = 0.082). A similar tendency was evident in some body composition values (skeletal muscle: P = 0.005; fat free mass: P = 0.006). Statistical significance did not reach the values of BMI (P = 0.131) and autonomic nervous system (P = 0.513; P = 0.585). Conclusion: Although our results suggest a positive trend in affecting the quality of life of patients after breast cancer treatment by exercises, similar research needs to be repeated in a larger study to confirm our results.
INTRODUCTION: The aim of this prospective randomised study was to evaluate clinical results and rotational stability at least 2 years after single-bundle anatomic anterior cruciate ligament reconstruction using a quadriceps tendon graft with bone block (BT) and bone-patellar tendon-bone graft (BTB). MATERIALS AND METHODS: In both groups (BT and BTB), 40 patients selected prospectively at random were evaluated. The mean follow-up after the surgery was 28 months (range 24-33 months). A navigation system was used to measure rotational stability of the knee joint. Cincinnati, Lysholm, and IKDC scores and visual analog score (VAS) were used to evaluate clinical results and the non-parametric Wilcoxon test was used for the statistical analysis. RESULTS: After the BT reconstruction, the mean internal rotation of the tibia (IR) was 9.5°. In the contralateral healthy knee joint, IR was 8.6° at average. After the BTB reconstruction, the mean IR was 9.9°. In the contralateral healthy knee joint, IR was 8.7° at average. We did not find any statistically significant difference in IR stability between BT and BTB reconstruction. In terms of clinical results, regarding the VAS, patients perceive significantly more pain after the BTB reconstruction (p < 0.05). Kneeling was reported more difficult and painful after BTB reconstruction. CONCLUSIONS: The BT reconstruction of the ACL provides similar clinical results, less pain, better flexion and the same rotational stability of the knee in comparison with the BTB reconstruction.

PURPOSE OF THE STUDY Knee injuries accompanied by anterior cruciate ligament (ACL) tears can also result in rotational instability of the joint. Subsequent insufficient rotational stability after the ACL reconstruction can be a direct consequence also of injuries to lateral knee structures, specifically the anterolateral ligament (ALL). This residual postoperative rotational instability may be prevented by multiple surgical techniques. The purpose of this study was (1) to evaluate the knee stability in internal rotation after the "anatomical" single-bundle (SB) anterior cruciate ligament reconstruction together with ALL reconstruction compared to the double-bundle (DB) ACL reconstruction two years after surgery; (2) to compare the knee joint stability after the ACL and ALL reconstruction with the healthy contralateral knee joint. MATERIAL AND METHODS All the measurements were conducted by the computer navigation system. The study included 20 patients after the single-bundle ACL and ALL reconstruction and 20 patients after the double-bundle ACL reconstruction. The follow-up examination was carried out at 25 months after surgery on average (24 months at least). All measurements were performed in both the healthy and operated knee. Once the data necessary for navigation were determined, the patient remained in standing position with both feet firmly placed on the mat with intermalleolar distance of 20 cm. Then, at 30-degree flexion of the knee joints, the patient first performed the joint internal rotation by trunk torsion, followed by external rotation. Each measurement was repeated 3 times. A non-parametric t-test was used for statistical processing. RESULTS The mean internal rotation in the injured knee joint was 19.1 degrees preoperatively and 8.1 degrees postoperatively, while in the healthy knee it was 8.4 degrees. External rotation was not assessed. The reported internal rotation in the knees after DB ACL reconstruction was 9.2 degrees (p ≥ 0.05). DISCUSSION The double-bundle ACL reconstruction is a complex technique that can lead to many intraoperative and postoperative complications. Grafts harvested from both hamstrings can have an effect on the rotational stability of the joint. In order to restore the knee rotational stability with fewer potential complications, the method of choice can be the ACL reconstruction using the quadriceps femoris muscle graft and the ALL reconstruction using the gracilis muscle graft, leaving the semitendinosus tendon intact. CONCLUSIONS The obtained values reveal that the single-bundle ACL reconstruction in combination with ALL reconstruction results in the same internal rotational stability in the knee joint as the double-bundle ACL reconstruction. Similar joint rotational stability is observed in all the knee joints reconstructed with the use of these techniques and in the contralateral healthy knee joint. Key words: anterolateral ligament, anterior cruciate ligament, internal rotational stability, objective measurement.

Cílem následujícího textu je nastínění problematiky diagnostiky a terapie aseptických nekróz. Jedná se o početnou skupinu onemocnění pohybového aparátu nejasné etiologie, vznikající anatomicky v predilekčních lokalizacích a zejména v mladém věku jedince. Vzhledem k často nízkému věku pacientů je diagnostika a léčba doménou dětské ortopedie. V dospělé ortopedii se setkáváme převážně s následky těchto onemocnění. Mnohdy jediným řešením pozdních následků onemocnění je chirurgická intervence. Nejasná etiologie onemocnění, různé variace klinických symptomů a často kontroverzní názory na léčbu dělají z aseptických nekróz nejednoduchou ortopedickou nosologickou jednotku. Součástí práce jsou i radiologické nálezy z klinické praxe s ukázkou možného chirurgického řešení.
The aim of the following article is to summarize problems of diagnosis and treatment of avascular or aseptic necrosis. It is a large group of diseases of the musculoskeletal system of unclear etiology, arising anatomically in specific localizations and especially at young age of the individual. Due to young age of patients the diagnosis and treatment is mainly dealt by pediatric orthopeadic surgeons. In adult orthopaedics, we mainly confront with the consequences of these diseases. The late consequences of the disease often lead to surgical way of treatment. The unclear etiology, various variations of symptoms and often controversial opinions on treatment make aseptic necrosis a difficult orthopaedic diagnosis. The article also includes radiological findings from clinical practice with a demonstration of the possible surgical solution.
Bolesti v krajině kyčelního kloubu mají příčinu v mnoha patologických procesech. Diferenciální diagnostika je velice složitá a zdlouhavá. Avaskulární nekróza hlavice kosti stehenní může být jednou z možných příčin bolestí mladých aktivních jedinců s výrazným ovlivněním jejich dalšího života. Tento text shrnuje aktuální poznatky v etiopatogenezi, diagnostice a léčbě idiopatické avaskulární nekrózy hlavice kosti stehenní (AVN).
Pain in the landscape of the hip joint has a cause in many pathological processes. Differential diagnosis is very complex and lengthy. Avascular necrosis of the femoral head can be one of the possible causes of pain in young active individuals with a significant impact on their further life. This text summarizes current knowledge in etiopathogenesis, diagnosis and treatment of idiopathic avascular necrosis of the femoral head (AVN).
PURPOSE OF THE STUDY The elbow is a highly constrained synovial hinge joint that frequently becomes stiff after injury. Grade 4 elbow stiffness (ankylosis) is a strongly limiting factor in the patient s daily activities and is difficult to treat. Hinged external fixation of the elbow provides the advantages of static fixation with the benefits of continued motion of the joint. The goal of our study was to assess the improvement in the range of motion of the elbow after surgical arthrolysis using a posterior extensile approach to the joint with or without using external fixation. MATERIAL AND METHODS Sixteen patients aged between 19 and 46 years with grade 4 elbow stiffness were operated on. The stiffness was caused by the following pathologies: 7 elbow dislocations, 3 radial head fractures, 4 distal humeral fractures, 2 fracture-dislocations. The average range of motion before surgery was 14° (range 0°-20°). The average interval between primary injury and arthrolysis was 24 months (9-60 months). The clinical assessment before and after the surgery was based on the Mayo Elbow Performance Score (MEPS). The average follow-up was 30 months (18-50 months). Arthrolysis was completed by application of an external fixator in eight patients. RESULTS A few common complications were observed, including the injury to adjacent neurovascular structures (two cases of temporary irritation of the ulnar nerve, one case of temporary irritation of the radial nerve) and three cases of pin-track infections. None of the patients showed elbow instability. In Group I, in which external fixation was used, the average MEP score increased from 51 points (range, 30 to 70) to 78 points (range, 55 to 90). The average range of motion at the final follow-up was 93° (range, 75°-135°). In Group II, in which no external fixation was used, the average MEP score increased from 53 points (range, 35 to 70) to 76 points (range, 55 to 85). The gain in flexion-extension was 88° (range, 65°-135°). The final improvement in the range of motion depended mostly on the severity of preoperative stiffness and subsequent surgery. DISCUSSION The surgical arthrolysis of the ankylosed elbow is not a procedure commonly performed by majority of hospitals. A precise surgical technique is a prerequisite for success of the procedure. The type of injury did not seem to influence the final result. Articular external fixation potentially provides stability while permitting the movement. CONCLUSIONS Open arthrolysis of a severe elbow contracture results in a substantial gain in motion (with or without using elbow external fixation) and gives reliable long-lasting results. The minimal improvement in motion provided by the hinge fixator does not justify the associated increase in the risk of complications. Key words:stiffed elbow, arthrolysis, external fixation.
