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 pechnique 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.

The purpose of this study was to evaluate the effectiveness of the minimally invasive sacroiliac joint stabilization by triangular titanium implants in patients with sacroiliac joint dysfunction. MATERIAL AND METHODS The prospective study evaluated the patients who had underwent a minimally invasive sacroiliac joint stabilization for sacroiliac joint dysfunction with the use of iFuse® implants. The surgery was performed solely under fluoroscopic guidance or together with the use of O-arm O2® mobile imaging system. The clinical condition, the Visual Analogue Scale preoperatively and one year postoperatively, previous surgeries in the lumbar spine region, the use of O-arm and occurrence of complications were recorded. The minimum follow-up period was 1 year. RESULTS The group was composed of 20 patients, of whom 4 men and 16 women. The mean age was 48.9 years. The surgeries covered 21 sacroiliac joints. Improvement of the clinical condition was reported in 17 cases (81.0%), no relief was observed in 4 cases (19%). The mean VAS score was 6.1 points preoperatively and decreased to 2.9 points postoperatively (p=0.0001). CONCLUSIONS The minimally invasive sacroiliac joint stabilization should be reserved for patients experiencing an intractable pain originating from the sacroiliac joint, in whom all non-operative therapy failed. Key words minimally invasive sacroiliac joint stabilization, sacroiliac joint dysfunction, O-arm.PURPOSE OF THE STUDY The increasing number of hip fractures puts enormous demand on our level 1 trauma centre. Because we have to synchronize hip fracture treatment with all other injuries delays to surgery can occur. In this study, we analysed the reasons for delay to surgery and how it impacts on mortality of hip fracture patients in our institution. MATERIAL AND METHODS We retrospectively studied 641 patients operated for hip fractures in one year period. Investigated characteristics were age, gender, American Society of Anaesthesiologists score (ASA), time of hospital admission, time of surgery, type of surgery, anticoagulant therapy (ACT) and non-routine pre-operative tests (NRPT). Trochanteric (TF) and femoral neck fractures (FNF) were analysed separately. The surgery in first 48 hours was considered early. The time of death was obtained from the federal database. Univariate and multivariable analysis were performed. check details P-values less then 0.05 were considered statistically significant. RESULTS All tested characteristics were significantly different in both time groups. Delay to surgery was significantly influenced by the type of surgery - arthroplasty, odds ratio (OR) 17.2, ACT (OR 6.9) and NRPT (OR 4.0) in FNF group of patients and by ACT (OR 31.1) and ASA (OR 2.2) in TF. 30-day mortality rate was 5.1% and 1-year mortality was 18.4%. ASA (OR 1.9), preinjury residence (OR 1.4) and age (OR 1.1) had statistical influence on survival, but not delay to surgery. CONCLUSIONS The majority of delays are due to unavailability of operative capacities, after patient optimization. We see solution in dedicated operation rooms and teams for hip fracture treatment. Mortality is influenced by the patients' characteristics, but not by delay to surgery. A multidisciplinary approach and skilled surgical teams are, besides early operation, the most important assurance of a good outcome. Key words trochanteric fracture, femoral neck fracture, timing, mortality.PURPOSE OF THE STUDY Two-year clinical results of a multicenter prospective randomized study in patients with arthroscopically treated Femoro - acetabular Impingement syndrome and concurrently performed microfracture for grade IV chondral lesions of the acetabulum. MATERIAL AND METHODS The study evaluated a group of 55 patients of the originally enrolled 92 patients with the underlying diagnosis of FAI syndrome with intraoperatively confirmed grade IV acetabular chondropathy of up to 4 cm2 in size, who had undergone a comprehensive hip arthroscopy (correction of structural cam-type and/or pincer-type deformity, labral refixation or partial labral resection etc.) performed by two experienced surgeons. The patients were randomized intraoperatively using a closed envelope method into two groups. In Group 1 (31 patients), microfractures for chondral defects was performed, while in Group 2 the patients underwent a defect debridement procedure only. The studied group included a total of 7 professional and 48 recreational athletes (33 men and 22 women), with the mean age of 34.
