Osteoid osteoma is a primary benign bone tumor with rare intra-articular occurrence. Our case report describes a rare case of a 21-year-old man with long-term severe pain in the right hip region caused by osteoid osteoma managed by arthroscopic excision. The clinical finding of pains and a limited range of motion did not correlate with the normal plain X-ray finding. The osteoid osteoma was suspected based on the CT scan. In literature, several methods of resection of intraarticular osteoid osteoma of the hip are described. Since our department has long specialised in arthroscopic hip surgery and based on the available examinations the tumor appeared to be located within the arthroscopic reach, we decided for arthroscopic resection of the tumor. Our study comprises a detailed description of the entire surgical procedure, the used arthroscopic approaches and the arthroscopic technique of tumor excision. The histological examination of samples taken from the mass confirmed the suspected osteoid osteoma. The success of arthroscopic excision of the tumor was later confirmed also by very positive postoperative recovery when the patient very soon experienced a considerable reduction of pain observed during our five-year follow-up of the patient (Day 13, Week 2 and 6, Year 1, 2 and 5). During the follow-up period, an increase of the Harris Hip Score (13.5 preoperatively vs 76.6/91/94/96/96 postoperatively) and a decrease in VAS (9 preoperatively vs. 3/1/1/1/1) were reported. The follow-up CT and MRI performed at 2 or 5 years after surgery did not show tumor recurrence. The case report includes also illustrations consisting of X-rays, CT and MRI scans before and after surgery as well as multiple scans taken intraoperatively. It has to be emphasized that this is a rare case and an evaluation of a larger group of patients would be necessary to verify the successful outcomes of arthroscopic technique in treatment of the hip joint osteoid osteoma.

PURPOSE OF THE STUDY We present the results of the retrospective study comparing the clinical outcomes of outside-in versus all-inside suture techniques of unstable RAMP lesions (RL) of the medial meniscus in patients with simultaneous ACL lesion with a minimum two-year follow-up. MATERIAL AND METHODS The retrospective evaluation covered two groups of patients who underwent the arthroscopic repair of unstable RL in combination with anterior cruciate ligament reconstruction (ACLR). Group 1 included 42 patients (28 men/24 women). Group 2 consisted of 36 patients (21 men/15 women). In Group 1, RL suture repair using the outside-in technique by posteromedial approach with absorbable PDS suture was performed, while in Group 2 the all-inside technique of RL suture via the standard anteromedial portal was applied using the Fast-Fix system (Smith Nephew, USA). The evaluation was done preoperatively and postoperatively with the mean follow-up of 27.9 months in Group 1 and 30.1 months in Group 2. The patients were assessed using the subjective IKDC score and the side-to-side difference (SSD) in ventral laxity was measured by Genourob (GNRB) laximeter at the applied pressure of 134 N and 250 N. Moreover, the failure rate of RAMP lesion repair, ACL graft, necessity of secondary partial meniscectomy and return to pre-injury level of sport were analysed. RESULTS The median IKDC score increased in Group 1 from 56 points preoperatively to 92 points postoperatively and in Group 2 from 58 points preoperatively to 90 points postoperatively (p>0.05). The median value of SSD in ventral laxity of the knee measured by the GNRB laximeter at the applied pressure of 134 N in Group 1 was 5.6 mm preoperatively and 1.9 mm postoperatively and in Group 2 it was 5.9 mm preoperatively and 2.3 mm postoperatively. At the pressure of 250 N, the median value in Group 1 was 7.9 mm preoperatively and 2.7 mm postoperatively and in Group 2 it was 8.1 mm preoperatively and 3.2 mm postoperatively. When comparing the SSD of the groups postoperatively, no statistically significant difference was found (p>0.05). Revision arthroscopy was performed in 8 patients. In 1 patient (2.4 %) in Group 1 and in 4 patients (11.1%) in Group 2 a rerupture of the RL of the meniscus occurred and partial meniscectomy was performed. In Group 2, statistically significant higher occurrence of the RL suture failure (p<0.05) was reported and there was a need to perform partial medial meniscectomy (p<0.05). The ACL graft failure was observed in 2 patients (4.7%) in Group 1 and in 3 patients (8.3%) in Group 2 (p>0.05). 31 evaluated patients (73.8%) from Group 1 and 24 patients (66.7%) from Group 2 (p>0.05) returned to the pre-injury level of sports activities. DISCUSSION When comparing the outcomes of individual techniques of the RL repair published in recent literature with our conclusions, we may state that the results of subjective as well as objective criteria achieved were similar to those reported by other authors worldwide. No study has so far been published which would compare the outcomes of the by us presented two surgical techniques of the RL suture in an ACL-deficient knee with a minimum follow-up of 24 months. CONCLUSIONS Both the surgical techniques of unstable RL repair in combination with the ACLR using a tendon graft result in a statistically significant improvement of clinical outcomes postoperatively. In Group 2, with the all-inside RL repair, a statistically significant higher failure rate of RL repair was confirmed as well as the need to perform secondary partial meniscectomy compared to Group 1. Key words: RAMP lesion, ACL-deficient knee, unstable medial meniscus lesion, repair of meniscus, all-inside technique, posteromedial technique, ACL reconstruction.
INTRODUCTION: Hip arthroscopy is a common procedure in hip preservation surgery. Its complication rate is relatively low. This prospective multicentric study evaluates complication rate in patients undergoing primary hip arthroscopy. MATERIALS AND METHODS: The study cohort consisted of 908 patients mean age of 37 years (14-67 years). Patients were prospectively included in the study in the years 2009-2017. All complications were recorded and evaluated. The minimum follow-up was 36 months. Results were statistically evaluated and risk factors for complications were identified. RESULTS: The overall complication rate was 7.3% (67/908 cases), the minor complication rate of 4.9% (45/908 cases) and the major complication rate 2.4% (22/908 cases). The most common severe complications were iatrogenic cartilage damage and instrument breakage, while the most common minor complications were perineal hypoaesthesia and heterotopic ossifications. The conversion rate to total hip replacement was 4.2% (39/908 patients). CONCLUSION: Hip arthroscopy is a safe procedure with low complication rates. Surgeon training and experience greatly influence the complication rates.

Tick-borne encephalitis exhibits profound inter-annual fluctuations in incidence. Previous studies showed that three-fifths of the variation can be explained in terms of four superimposed oscillations: a quasi-biennial, triennial, pentennial, and a decadal cycle. This study was conducted to determine how these cycles could be influenced by climate change. Epidemiological data, spanning from the 1970s to the present, and originating from six regions/countries bridging Scandinavia and the Mediterranean, represented a temporal/latitudinal gradient. Spectral analysis of time series was used to determine variation in the cycles' length/amplitude with respect to these gradients. The analysis showed that-whereas the lengths of the shorter cycles do not vary substantially-cycles in the decadal band tend to be longer southwards. When comparing the disease's oscillations before- and after the mid-1990s, a shift towards longer oscillations was detected in the pentennial-decadal band, but not in the biennial- triennial band. Simultaneously, oscillations in the latter band increased in intensity whereas the decadal oscillations weakened. In summary, the rhythm of the cycles has been altered by climate change. Lengthened cycles may be explained by prolonged survival of some animal hosts, and consequently greater inertia in herd immunity changes, slowing down a feedback loop between the herd immunity and amount of virus circulating in nature.
