INTRODUCTION: Although intraarticular tranexamic acid (IA-TXA) administration or drainage clamping are popular methods used to reduce blood loss after total knee replacement (TKR), the protocol remains controversial. We aimed (1) to establish new protocols through investigating whether two methods, that is, low-dose (500 mg) IA-TXA plus 30-min drain clamping and drainage clamping for the first 3 h without IA-TXA, can reduce blood loss and blood transfusion after unilateral TKR and (2) to make recommendations related to clinical application...

BACKGROUND: Previous epidemiological surveys conducted in Japan highlighted problems with conventional approaches to treating chronic musculoskeletal pain. On the basis of prior studies, we initiated the "longitudinal investigation of chronic musculoskeletal pain" in 2010. In our first two reports, we revealed a high prevalence of chronic musculoskeletal pain, low satisfaction with treatment, and reduced quality of life. Those with severe and consistent low back pain had the highest risk of the persisting pain...

BACKGROUND: Where is over 100 reconstruction techniques described for acromioclavicular (AC) joint reconstruction. Although, it is not clear whether the presence of the sternoclavicular (SC) joint influences the biomechanical properties of native AC ligaments and reconstruction techniques. The purpose of the present study was to investigate the biomechanical properties of native AC joint ligaments and two reconstruction techniques in cadavers with the SC joint still present. MATERIALS AND METHODS: We tested eight fresh-frozen cadaver hemithoraces for superior translation (70 N load) and translation increment after 1000 cycles (loading from 20 to 70 N) in a controlled laboratory study...

PURPOSE: Arthroscopic treatment of shoulder instability has some advantages (including short surgical time, less morbidity, less postoperative pain, reduced hospitalization time, and decreased risk of complications) compared with open procedures. We performed a prospective study comparing open repair with arthroscopic repair for recurrent anterior shoulder instability. The aim was to clarify the relative effectiveness of open Bankart repair plus inferior capsular shift (OBRICS) and arthroscopic Bankart (AB) repair without augmentations with approximately 5 years of follow-up...

Mobile-bearing Oxford medial unicompartmental knee arthroplasty (UKA) has been widely used and has produced good results in the treatment of medial compartmental osteoarthritis. But it is associated with the potential risk of meniscal bearing dislocation. Symptoms caused by most meniscal bearing dislocations include acute pain, knee swelling, and locking. We report two unusual cases of meniscal bearing spinning of 180° without remarkable symptoms, which would have been easily missed if we had not watched carefully...

INTRODUCTION: Steroid and local anaesthetic injection to the acromioclavicular joint (ACJ) is a very common diagnostic and therapeutic procedure, which is often performed in the outpatient department. However, it can be difficult to localize this joint because of its small size, presence of osteophytes and variable morphology in the population. We performed a study to determine whether the use of an image intensifier (X-ray guidance), in theatre, improves the accuracy of this injection...

PURPOSE: The postoperative protocol after arthroscopic rotator cuff repair (ARCR) is still controversial. Some surgeons recommend slower rehabilitation in order to improve the integrity of the repair, while others prefer early range-of-motion (ROM) exercise to avoid postoperative stiffness. The purpose of this study was to determine target ROM (T-ROM) measurements at 3 months after ARCR that are predictive of eventual full recovery without structural failure. METHODS: The cases consisted of 374 shoulders in 360 patients who underwent primary ARCR and were followed up for at least 2 years...

BACKGROUND: Tears of the glenoid labrum are common after dislocation of the glenohumeral joint. The outcome for healing or surgical reconstruction of the glenoid labrum relies on the extent of its vascularization. This study aims to evaluate the glenoid labrum blood supply and to determine its regional vascularity. MATERIALS AND METHODS: A total of 140 shoulders (30 male and 40 female cadavers) were examined: mean age 81.5 years, range 53-101 years. All blood vessels around the glenohumeral joint were dissected and recorded...

OBJECTIVE: Tibiofemoral geometries in a total knee replacement (TKR) affect the performance of an implant during activities of daily living. The specially shaped components of a surface-guided TKR aim to control the tibiofemoral motion, such that a normal pattern of motion is achieved, even at high flexion angles. The purpose of this study was to assess the influence of the design parameters on the kinematic behavior of such an implant. A combination of design variables was determined that resulted in the least deviation from the design kinematic target...

BACKGROUND: Various radiographic measurements that describe humeral head coverage by the acromion and the effect on rotator cuff pathology have been reported. This study aimed to describe and validate a new radiographic measurement, the acromiohumeral centre edge angle (ACEA). METHODS: We compared the ACEA on computed tomography (CT) and plain X-ray to determine whether X-ray is accurate for measuring this angle. We then compared the results from this control population with 107 patients with acute rotator cuff tears...
