PURPOSE: While tendon degeneration has been known to be an important cause of rotator cuff disease, few studies have objectively proven the association of tendon degeneration and rotator cuff disease. The purpose of this study was to investigate changes of tendon degeneration with respect to the stage of rotator cuff disease. METHODS: A total of 48 patients were included in the study: 12 with tendinopathy, 12 with a partial-thickness tear (pRCT), 12 with a full-thickness tear (fRCT), and 12 as the control...

PURPOSE: Atraumatic microinstability of the hip is felt to be a cause of intra-articular pathology, particularly tears of the anterior labrum. The purpose of this study is to evaluate a consecutive series of patients with atraumatic hip microinstability that resulted in anterior labral and cartilage pathology, treated with hip arthroscopy and capsular plication without any associated bony procedures. METHODS: Thirty-two patients underwent hip arthroscopy and suture capsular plication for the treatment of hip instability without concomitant bony resections of the acetabulum or proximal femur between November 2009 and November 2012 and were followed for a minimum of 12 months...

PURPOSE: Post-operative infection after arthroscopically assisted anterior cruciate ligament (ACL) reconstruction is a rare but severe complication, particularly for young and active patients. It is unclear whether the prevalence of knee infection is correlated with the type of sports or the level of performance. METHODS: From 2008 to 2012, the internal single-centre ACL registry of the FIFA Medical Centre of Excellence Regensburg was retrospectively screened for sex, age, time between isolated primary ACL rupture and surgery, surgical technique, rate of infection after ACL reconstruction and the type of sports practised...

PURPOSE: Studies comparing single- and double-bundle anterior cruciate ligament (ACL) reconstructions often include a combined analysis of anatomic and non-anatomic techniques. The purpose of this study was to compare the revision rates between single- and double-bundle ACL reconstructions in the Swedish National Knee Ligament Register with regard to surgical variables as determined by the anatomic ACL reconstruction scoring checklist (AARSC). METHODS: Patients from the Swedish National Knee Ligament Register who underwent either single- or double-bundle ACL reconstruction with hamstring tendon autograft during the period 2007-2014 were included...

PURPOSE: The shoulder manual resistance test is one of the common clinical assessments for patients with muscle weakness. However, there have been no studies investigating the threshold for muscle weakness. The purpose of this study was to clarify the threshold for muscle weakness in the shoulder manual muscle resistance test. METHODS: Fifty-three patients (37.9 ± 20.6 years old) with either rotator cuff tear (21 patients), superior labrum anterior-to-posterior (SLAP) lesion (7 patients), or Bankart lesion (25 patients) of one shoulder were administered three manual muscle resistance tests (abduction strength, external rotation, and belly press tests)...

PURPOSE: Vascularity of the subacromial bursa and rotator cuff tendons is key factors in the pathogenesis of subacromial bursitis and impingement syndrome, rotator cuff tendinitis, and rotator cuff tears. The purpose of this study was to investigate and describe blood supply to the cranial and caudal parts of the subacromial bursa and the vascularity of the rotator cuff tendons on the bursal side. METHODS: Fourteen fresh cadaveric shoulders from six females and eight males with a mean age of 71...

PURPOSE: The contralateral anatomy is regularly used as a reconstruction template for corrective osteotomies of several deformities and pathological conditions. However, there is lack of evidence that the intra-individual differences between both tibiae are sufficiently small to use the contralateral tibia as a 3D reconstruction template for complex osteotomies. The aim of this study was to evaluate the intra-individual side differences of the tibia in length, torsion, angulation, and translation using 3D measurement techniques...

PURPOSE: The purpose of this study was to evaluate the effects on knee biomechanics of rotating the distal end of the bone-patellar tendon graft 90° in anatomic single-bundle (SB) anterior cruciate ligament (ACL) reconstruction with a porcine model. METHODS: Twenty (n = 20) porcine knees were evaluated using a robotic testing system. Two groups and three knee states were compared: (1) intact ACL, (2) deficient ACL and (3) anatomic SB ACL reconstruction with (a) non-rotated graft or (b) rotated graft (anatomic external fibre rotation)...

PURPOSE: The purpose of this study was to analyse the relationship between long head of the biceps brachii (LHBT) lesions and subscapularis tears. The hypothesis was that a bicipital pulley might remain intact, even in the case of a subscapularis tear. METHODS: Between 2010 and 2011, all patients who had a primary arthroscopic repair of a subscapularis tear were potentially included in this prospective study. The outcome of interest was the prevalence and type of arthroscopic lesions of the LHBT and bicipital pulley...

Femoral ACL avulsion fractures were not well described in the literature, and there were only several reports describing mostly immature patients. A case of 50-year-old man with ACL femoral attachment avulsion fracture after pivoting knee injury during skiing was presented. The bony attachment was reduced and fixed arthroscopically with screws. Four months after surgery, patient was allowed to return to full sport activity with full range of motion. He was able to perform a one-leg-hop test without limitation, and the strength of quadriceps muscle was comparable to contralateral side...

PURPOSE: A number of validated scores are available to monitor clinical outcome after knee arthroplasty. The current study examines whether WOMAC, KOOS, or SF-12 scores have a predictive value to identify patients that require total knee arthroplasty within 1 year. METHODS: The Osteoarthritis Initiative includes 4684 patients in two groups: incidence subcohort (Group A, n = 3284) and progression subcohort (Group B, n = 1400). A total of 278 patients reached the endpoint "unilateral knee replacement" (Group A = 96; Group B = 182)...

PURPOSE: One of the key factors responsible for altered kinematics and joint stability following contemporary total knee arthroplasty (TKA) is resection of the anterior cruciate ligament (ACL). However, ACL retention can present several technical challenges, and in some cases may not be viable due to an absent or nonfunctional ACL. Therefore, the goal of this research was to investigate whether substitution of the ACL through an anterior post mechanism could improve kinematic deficits of contemporary posterior cruciate ligament (PCL) retaining implants...

PURPOSE: Flexion instability following total knee arthroplasty (TKA) is a common indication of early revision. The association between the objective anteroposterior (AP) laxity direction in mid-range flexion and the subjective healing of instability remains unclear; thus, this study aimed to clarify this association. METHODS: In this study, 110 knees (74 females, 92 knees; 16 males, 18 knees) with medial pivot implants were examined with a median age of 79 (range 60-92) years for a median follow-up duration of 22 (range 6-125) months...

PURPOSE: To examine, with a navigation, whether the final component alignments correlate with alignment of the bone resection surfaces in cemented total knee arthroplasty (TKA), and to evaluate the factors affecting alignment deviation. METHODS: A total of 222 patients (276 knees) who underwent navigation-assisted TKA between September 2012 and January 2014 due to osteoarthritis were retrospectively reviewed. The deviation between the alignment of bone resection surfaces and the final alignment of femoral and tibial components was measured...
