PURPOSE: This study provides an insight on the extent of muscular variability at the suprascapular notch and elaborates on its anatomical interference in suprascapular nerve arthroscopic decompression procedures. METHODS: The suprascapular notch was dissected and its muscular topography was observed in 115 cadaveric specimens. High resolution imaging of the suprascapular notch was captured by a handheld digital microscope (Q-scope). The supraspinatus and subscapularis muscles were traced as they course at the suprascapular notch vicinity. The omohyoid muscle attachment onto the suprascapular ligament was measured. A scoping review and meta-analysis were done to investigate the observed rare muscular variants. RESULTS: In 3.48%, the suprascapular notch anterior surface was fully covered by the subscapularis muscle. The omohyoid muscle inserted onto the suprascapular ligament in 31.25% and extended up to 3/4th of the suprascapular ligament length in 2.61%. Two rare variant muscles were encountered: subclavius posticus muscle and a newly reported "coracoscapularis muscle". CONCLUSIONS: Four categories of muscles with topographical relationship to the suprascapular notch and its arthroscopic feasibility have been classified: (1) constant muscles not intervening with the suprascapular notch space - supraspinatus muscle; (2) constant muscles with variable positions that can intervene with the suprascapular notch space - subscapularis muscle; (3) constant muscles with variable positions that can intervene with the surgical approach - omohyoid muscle; (4) variable muscles intervening with the suprascapular notch space and surgical approach - subclavius posticus and coracoscapularis muscles. This study elucidates the necessity to assess/secure the omohyoid muscle attachment onto the suprascapular ligament in suprascapular nerve decompression ligamentectomy.

PURPOSE OF THE STUDY: In our study, it was aimed to evaluate the efficacy of microfracture and retrograde subchondral drilling on clinical outcomes in patients who underwent ankle arthroscopy due to osteochondral lesion of medial talus. MATERIAL AND METHODS: Twenty eight patients with osteochondral lesion of talus less than 1.5 cm2 treated with ankle arthroscopy were evaluated retrospectively. Microfracture was performed in 16 patients and retrograde subchondral drilling was performed in 12 patients that there was no loss of integrity in the cartilage layer or cartilage layer is partially preserved during ankle arthroscopy. Postoperative evaluations of the patients were done with Foot and Ankle Ability Measure (FAAM) and results of both group were compared statistically. RESULTS: The mean activities of daily living scale was 93.4±3.2 and sportive activity scale was 90.1±5.7 in the retrograde drilling group. In the micro-fracture group, mean activities of daily living scale was 93.8±4.1 and mean sportive activity scale was 88.9±9.5. No significant difference was found as a result of statistical comparisons of both groups results. DISCUSSION: It has been determined that the size and preservation of the integrity of talar osteochondral lesions are important factors on clinical results. Results of arthroscopic debridement, microfracture and drilization are not good in lesions larger than 1.5 cm2 and lesions with impaired integrity. In our study, depending on the general literature, osteochondral lesions in talus were less than 1.5 cm2 in patients who underwent arthroscopic micro fracture and retrograde drilling. CONCLUSIONS: Both microfracture and retrograde subchondral drilling are effective treatment methods with good clinical results for talar osteochondral lesions less than 1,5cm2 . Retrograde subchondral drilling can be an alternative treatment method with the reliability of clinical results in patients with no loss of the integrity of the cartilage layer or cartilage layer is partially preserved. KEY WORDS: talus, osteochondral lesion, microfracture, subchondral drilling.

PURPOSE: The authors evaluated a cohort of 37 patients with histologically verified synovial chondromatosis (SC) between 2013 and 2022. METHODS: The cohort consisted of 37 patients (26 women, 11 men). 36 patients had unilateral involvement, while one patient had bilateral involvement. The average age of the patients was 54.77 years. The authors used the Milgram histopathological classification. They evaluated SC localisation, clinical symptoms, diagnostics and treatment (including recurrence incidence) in this cohort. RESULTS: In 31 patients (83.7%) SC affected only the upper joint space in one patient (2.7%) the lower space, and in five patients (13.6%) both spaces. 12 patients (32%) were Milgram Stage 1 (presence of synovial metaplasia without loose bodies), eight patients (22%) were Stage 2 (presence of synovial changes, loose bodies), and 17 patients (46%) were Stage 3 (presence of loose bodies, no synovial changes). Pain was the dominant clinical symptom (32 patients, 86.4%). Treatment consisted of arthroscopy and open surgery. Two patients underwent primary reconstruction and total TMJ replacement. Treatment was successful in 89.2% of cases (33 patients), with four (10.8%) patients suffering recurrence. CONCLUSION: As this patient cohort shows, pain was the dominant symptom in patients with SC. Magnetic resonance imaging is fundamental in the diagnosis of SC, demonstrating pathological findings even in patients for whom an initial X-ray was negative. These were mainly patients with Milgram Stages 1 and 2 without calcification, loose bodies or pathological changes of the bone structures. This is why the authors recommend MRI for any patient experiencing pain for more than three months, and if this reveals an effusion, joint distension or intraarticular soft tissue mass, they will always indicate arthroscopy. Thorough follow-up of patients is recommended, although SC recurrence is not very frequent. The authors recommend follow-up one, three and six months after surgery, and then annually for the first five years after surgery. They recommend follow-up MRI one, two and five years after surgery.

PURPOSE OF THE STUDY A global bibliometric comparison of the level of scientific interest and output in the two research areas hip and knee arthroscopy (H-ASC and K-ASC) was carried out. In addition, the different degrees of publication activity in the countries and institutes performing this research were investigated. MATERIAL AND METHODS Publications from 1945-2020 listed in the Web of Science Core Collection were included in the study. Using the web application Science Performance Evaluation (SciPE), quantitative and qualitative aspects were evaluated. Subsequently, the date of publication, author information, and other metadata were analysed. RESULTS Since 1945, 3,924 studies have been published on K-ASC and 2,163 on H-ASC. The majority of the publications which have appeared since 2016 dealt with the topic of H-ASC (H-ASC: 241.2 publications/year; K-ASC: 217.4 publications/year). The USA published the most on both topics (H-ASC: 1,123 publications; K-ASC: 1,078 publications). More countries and institutes participated in K-ASC (3,008 institutes, 82 countries) than in H-ASC (103 institutes, 57 countries). The ten institutes with the most publications accounted for 36.71% and 12.34% of all publications on H-ASC and K-ASC, respectively. H-ASC received 78.12% of its funding from private sponsors while K-ASC was supported mainly by governmental/nonprofit sponsors (70.92%). CONCLUSIONS This study provides the first scientific comparison between H-ASC and K-ASC. Measured by qualitative and quantitative aspects, K-ASC was the most flourishing research area overall. In the last ten to five years, interest has shifted towards HASC with an increasing number of publications and a higher rate of citations. Key words: knee arthroscopy, hip arthroscopy, bibliometric comparison.

PURPOSE: Differentiating the anatomical variations of the anterosuperior portion of the glenoid labrum from pathologies is important to avoid unnecessary iatrogenic complications resulting from inaccurate diagnosis. Additionally, the presence of several variations was reported to be conductive to lesions involving the glenoid labrum. Thus, the aim of this study was to state the prevalence rates of the sublabral recess, sublabral foramen, and the Buford complex, and to verify their association with labral lesions. METHODS: Systematic search of electronic databases was conducted to gain potentially eligible literature. Suitable studies were selected in a two-round screening, and relevant data were subsequently extracted. Calculation of the pooled prevalence estimates, including sub-analyses on cohort size, study type, and geographical variance, was conducted. Pooled analysis of risk ratios (RR) was used to assess the conductive nature of the discussed variants to superior labrum anterior to posterior (SLAP) lesions. RESULTS: The screening resulted in selection of 20 studies investigating the morphological features of the glenoid labrum, consisting of 7601 upper limbs. On the bases of random-effects meta-analysis the sublabral recess, sublabral foramen and Buford complex occur with a pooled prevalence of 57.2% (95% CI 30.0-84.4%), 13.5% (95% CI 8.2-18.9%), and 3.0% (95% CI 1.5-4.5), respectively. Moreover, individuals with Buford complex have RR 2.4 (95% CI 1.3-4.7) of developing SLAP lesions, especially type II (95.5%; 95% CI 86.1-100%), whereas such risk for sublabral recess and sublabral foramen was not statistically significant. CONCLUSION: Morphological variants of the glenoid labrum posing diagnostic confusion are frequently observed. Gradually, the Buford complex may be a predisposing factor for sustaining a SLAP lesion.

PURPOSE OF THE STUDY The aim of this study is to confirm that the involvement of arthroscopy in the surgical treatment of painful elbow syndrome, when proper and long enough conservative treatment failed, has better results than open radial epicondylitis surgery alone. MATERIAL AND METHODS A total of 144 patients included 65 men and 79 women, with the mean age of 45.3 years, namely 44.4 years (range 18-61 years) in men and 45.8 years (range 18-60 years) in women. Each patient was clinically examined, an anteroposterior and lateral X-ray of the elbow were performed, and proper therapy was chosen - either primary diagnostic and therapeutic arthroscopy followed by open epicondylitis surgery or primary open epicondylitis surgery alone. The treatment effect was evaluated by using the QuickDASH (Disabilities of the Arm, Shoulder and Hand) scoring system at 6 months after surgery. RESULTS Out of the total group of 144 patients, 114 (79%) patients completed the questionnaire. All the results of the QuickDASH score in our group of patients are in the better half (0-5 very good, 6-15 good, 16-35 satisfactory, over 35 poor), with the mean value 5.63 (in men the mean value was 2.95-2.27 for the combination of arthroscopic and open procedure of LE, 4.55 for open procedure of LE, while in women the mean value was 7.50-6.82 for the combination of arthroscopic and open procedure of LE, 9.09 for open procedure of LE only). Altogether 96 patients (72%) experienced full pain relief. In patients treated with a combination of arthroscopic and open surgery, a higher percentage of patients reported full relief (53 patients, 85%) compared to the patients treated with the open method alone (21 patients, 62%). DISCUSSION By involving arthroscopy in the surgical treatment of patients with lateral elbow pain syndrome after unsuccessful conservative treatment, a successful and early solution to the problem was achieved in 72% of patients. The advantage of elbow arthroscopy over the conventional approach to the treatment of lateral epicondylitis consists mainly in the opportunity to observe intraarticular structures, thus provide a detailed view of the entire joint without the need for direct extensive joint opening, which makes it possible to exclude other causes of problems (e. g. chondromalacia of the radial head, loose body and other intraarticular abnormalities). At the same time, we can treat this source of problems with minimum burden placed on the patient. CONCLUSIONS Arthroscopic examination of the elbow joint makes it possible to diagnose all potential intraarticular sources of difficulties. Simultaneous elbow arthroscopy and open treatment of radial epicondylitis (release of ECRB or EDC, ECU, necrotic tissue excision, deperiostation and radial epicondyle microfractures) is a safe method with low morbidity, faster rehabilitation and return to the original activities based on subjective evaluation of patients and objective scoring. Key words: lateral epicondylitis, radiohumeral plica, elbow arthroscopy.
