PURPOSE AND HYPOTHESIS: The principal purpose of this paper was to identify whether femoral notch morphology was different in females without anterior cruciate ligament (ACL) injury from those with ACL injury. Magnetic resonance imaging (MRI) was used to assess the femoral notch type, notch width index and 'α angle' in female patients and measure these differences. METHODS: This is a retrospective case control study of 119 female patients, 58 with ACL injury and 61 patients without ACL injury who underwent knee MRI between March 2014 and April 2016...

PURPOSE: A few studies have detected associations of post-operative tunnel enlargement with sex, age, and the timing of anterior cruciate ligament reconstruction (ACLR). The aim of the present study was to investigate the correlation between post-operative tunnel enlargement following ACLR using hamstring tendon autografts and preoperative factors. The authors hypothesized that tunnel enlargement is associated with age in patients undergoing ACLR. METHODS: One hundred and six patients (male, n = 57; female, n = 49; mean age, 26...

PURPOSE: Magnetic resonance (MR) imaging is common in structural and qualitative assessment of the rotator cuff post-operatively. Rotator cuff integrity has been thought to be associated with clinical outcome. The purpose of this study was to evaluate the inter-observer reliability of cuff integrity (Sugaya's classification) and assess the correlation between Sugaya's classification and the clinical outcome. It was hypothesized that Sugaya's classification would show good reliability and good correlation with the clinical outcome...

PURPOSE: The relationship between the duration of operative time (DOT), healing response and patient outcome has not been previously investigated. An enhanced healing response related to DOT may potentiate repair processes, especially in hypovascular and sparsely metabolized musculoskeletal tissues such as tendons. This study aimed to investigate the association between DOT and the metabolic healing response, patient-reported outcome and the rate of post-operative complications after acute Achilles tendon injury...

PURPOSE: The purpose of this study was to analyse patient and injury characteristics as well as arthroscopic findings in a prospective cohort of ACL-injured patients with or without an associated ramp lesion. METHODS: Two hundred and twenty-four patients undergoing a primary (n = 196) or revision (n = 28) ACL reconstruction were included. The presence of a ramp lesion was determined by a systematic arthroscopic inspection of the posteromedial compartment. Chi-square tests were used to compare the population of ACL-injured patients with and without a ramp lesion regarding sex, age, body mass index, previous ACL injuries, sport before injury, and injury characteristics...

PURPOSE: A detailed structural anatomy of the posterosuperior shoulder capsule and "glenocapsular ligament" is still rather unknown. The purpose of this study was meticulously to investigate and describe the structure and blood supply of the glenocapsular ligament on the posterosuperior shoulder joint capsule. METHOD: Sixteen fixed and twelve fresh cadaveric shoulder specimens with a mean age of 73.4 (±6.4) years were analysed. Dissection without arterial injection was performed on the 16 fixed specimens-using an alcohol-formalin-glycerol solution...

PURPOSE: Little is known about the arthroscopic or radiographic outcomes after arthroscopic microfracture of osteochondral lesions of the talus (OLTs). The purpose of this study was to investigate tissue growth after arthroscopic microfracture of OLTs using computed tomography arthrography (CTA) and to identify the relationship between CTA findings and clinical outcomes. We hypothesized that the morphology of the repaired tissue would be similar to that of normal anatomy and correlate with the clinical outcomes...

PURPOSE: After revision anterior cruciate ligament reconstruction (ACLR), the rate of return to the pre-injury type of sport (RTS type) is low and graft choice might be an important factor. The aim of this study was to determine whether there is a difference in outcome after revision ACLR using a patellar tendon allograft compared to an ipsilateral patellar tendon autograft. It was hypothesized that the rate of RTS type using an ipsilateral patellar tendon autograft will be superior to using patellar tendon allograft...

PURPOSE AND HYPOTHESIS: Trochlear osteotomy is a rarely performed procedure, only indicated in selected cases. Due to its nature, it can potentially lead to cartilage damage and subsequent early osteoarthritis. Satisfactory short-term results from lateral condyle-elevating osteotomy have previously been reported. The long-term effects of this procedure on clinical outcomes, patellar stability and radiological osteoarthritis are reported here. METHODS: Sixteen patients (19 knees) with patellar instability due to trochlear dysplasia were included...

PURPOSE: To compare the effectiveness of tenodesis and tenotomy in the treatment of long head of the biceps tendon (LHBT) lesions. The null hypothesis was that there is no difference in functional scores between the tenotomy and tenodesis groups. METHODS: A total of 69 patients with a combined supraspinatus tear and LHBT lesion aged over 40 years entered this prospective comparative study and were randomly assigned to the arthroscopic LHB tenotomy or tenodesis group...

PURPOSE: Fatty infiltration (FI) is known to be an irreversible change which continues degeneration after rotator cuff repair. Previous studies evaluated postoperative changes in FI using a preoperative baseline. This study aimed to investigate the changes in FI using an immediate postoperative baseline. We hypothesized that FI was progressed more when measured relative to an immediate postoperative baseline than to a preoperative baseline. METHODS: From 2008 to 2010, 77 patients who met the following criteria were included in this study: arthroscopic rotator cuff repair of a full-thickness rotator cuff tear and presence of preoperative (approximately 1 month before surgery), immediate postoperative (approximately 3 days after surgery), and 1-year postoperative (at least 9 months to 1 year after surgery) magnetic resonance imaging (MRI) undertaken...

PURPOSE: In adults, reconstruction of the medial patellofemoral ligament (MPFL) has shown good results. Treatment for recurrent patellar instability in children and adolescents with open growth plates, however, requires alternative MPFL reconstruction techniques. This study presents the outcomes of a minimally invasive technique for anatomic reconstruction of the MPFL in children using a pedicled superficial quadriceps tendon graft, hardware-free patellar graft attachment, and anatomic femoral fixation that spares the distal femoral physis...
