Background The main purposes of the present study were to evaluate the functional improvement, to identify the predictors of the clinical outcome after open surgical management of femoroacetabular impingement (FAI) in mid-term, and to determine 5-year survival rate. Methods In this retrospective study, the clinical data of 33 patients (34 hips) were evaluated. Sex, age, body mass index (BMI), type of FAI, duration of symptoms up to surgical treatment, internal rotation of the affected hip, improvement of the Harris hip score (HHS) in the first 2 years, joint space narrowing evaluated radiographically and classified according to Kellgren–Lawrence classification, and any labral tear were the independent variables. Harris hip score and degenerative arthritic changes at the latest follow-up were identified as outcome measures. Univariate and multivariate analyses were performed. The mean post-operative follow-up was 6 years. Results Harris hip scores at the latest follow-up were significantly worse in patients with a pre-operative age >35 years, BMI ≥25 kg/m2, internal rotation of the hip ≤10° grade 1 or 2 joint space narrowing, labral tear, and <15 points improvement of the HHS at the first 2 years follow-up. According to multivariate analysis; major predictors of the outcome were BMI, labral tear, and improvement of the HHS at the first 2 years. Conclusions A pre-operative BMI ≥25 kg/m2, labral tear, and <20 points improvement of the HHS in the first 2 years of surgery should be considered as the major predictors of the clinical outcome after open surgical management of idiopathic FAI.

Background: The purpose of this study was to assess the frequency of superior labrum anterior posterior (SLAP) lesions, long head of biceps tendon (LHBT) pathologies, and superior rotator cuff tears accompanying subscapularis tears. We hypothesised that LHBT lesions, superior rotator cuff tears, and especially SLAP lesions were very frequent with subscapularis tears. Methods: The digital files of patients who underwent shoulder arthroscopy were reviewed retrospectively. One hundred and eleven patients with subscapularis tears evident on surgery videos were examined. Superior labrum, LHBT, and superior rotator cuff lesions were investigated by the authors of this study. The statistical analyses were made with SPSS statistics software, and significance was set at P < 0.05 value. Results: There were 111 patients with both subscapularis tears and surgery videos. The mean age was 58.09 ± 10.21, and 63.1% of the patients were female. 98.2% of the 111 patients had a SLAP lesion. 7.2% of those were SLAP I and 91% were SLAP II lesions while 1.8% were healthy. The 75.7% of the patients had a LHBT pathology, and 83.8% had superior cuff tear. Conclusions: Subscapularis tears were almost always accompanied by SLAP lesions. On the other hand, biceps tendon pathologies and superior rotator cuff tears were also very frequent with subscapularis tears. Level of evidence: Prognostic study, Level IV (retrospective cohort study).

Background We aimed to evaluate cysts in the lesser tuberosity of humeral head seen on magnetic resonance imaging (MRI) and their relationship with subcoracoid impingement and subscapularis tears evident on arthroscopic surgery videos. Our hypothesis was that the cysts would be more frequent with subscapularis tears and in the case of subcoracoid impingement. Methods Patients who underwent shoulder arthroscopy between January 2010 and January 2016 were retrieved to evaluate subscapularis tears on surgery videos and lesser tuberosity cysts (LTC), coracohumeral distances (CHD) on both sagittal oblique and transverse sections of MRI retrospectively. There were 137 patients meeting the study criteria with subscapularis tear evident on surgery video and having preoperatively studied magnetic resonance images. All the tears were classified according to the Lafosse's system. The control group was constituted with 121 patients who underwent shoulder arthroscopy and were diagnosed with no subscapularis tear. Then, any statistically significant relationship between these parameters was investigated by the use of statistics software. Results The mean age (57), gender distribution (female for 67.1%), and involved shoulder (right for 62.8%) rate of the groups were statistically similar. The existence rate of LTC was 55.5% and 19% for the study and control groups, respectively (P = .000). The study group was then evaluated in two groups regarding the existence of a cyst in the lesser tuberosity. There was no statistical difference between these two groups in terms of coracohumeral distances and tear type (P > .05). The study group was also divided into two depending on the transverse section CHD whether it was under 7 mm or not. There was still no statistical difference between these subgroups in terms of a cyst existence (P > .05). The supraspinatus tear rate and age distribution was also not differing in patients with and without LTC. Conclusions The LTCs were significantly associated with subscapularis tears, and could be used as an indicator in the interpretation of MRI scans. However, there was no relationship between the subcoracoid impingement and LTCs.
