PURPOSE: It was hypothesized in this in-vitro study that positioning a K-wire intersecting the cutting plane at the theoretical lateral hinge location would limit the cut depth and help preserve the lateral hinge during the opening of the osteotomy. Objectives were (1) to compare the mechanical resistance of the hinge and the protective effect of leaving the K-wire during the opening procedure (2) to check if the K-wire would limit the depth of the osteotomy. METHODS: An ex-vivo mechanical study, testing 5 pairs of fresh-frozen tibias, was designed...

PURPOSE: Rupture of the contralateral Achilles tendon following Achilles tendon rupture can lead to devastating outcomes. However, despite the clinical importance, the risk factors and incidence of contralateral Achilles tendon rupture have not been well studied. This study aimed to determine the incidence of contralateral tendon rupture after Achilles tendon rupture and to identify associated patient characteristics. METHODS: Medical records for 226 consecutive patients with Achilles tendon rupture were retrospectively reviewed...

PURPOSE: To assess the percentage of patients achieving symmetrical knee function 6 months after primary anterior cruciate ligament (ACL) reconstruction (ACLR) and to identify factors affecting its achievement, in a large cohort. METHODS: Data were extracted from our clinic database. Patients who underwent primary ACLR from 2000 to 2015 and were assessed with the isokinetic quadriceps and hamstring muscles strength tests and single-leg-hop test at the 6-month follow-up were included in the study...

Tae-Hwan Yoon, Sung-Jae Kim, Chong-Hyuk Choi, Soon-Phil Yoon, Yong-Min Chun
PURPOSE: To investigate whether subscapularis integrity and compensatory teres, minor hypertrophy is associated with maintaining relatively good function and tolerable pain levels during non-operative treatment. METHODS: This study included 108 patients with irreparable, massive rotator cuff tears involving at least two tendons and stage III or IV muscle hypotrophy and fatty infiltration on oblique sagittal magnetic resonance imaging, in which even a partial repair does not seem feasible...

PURPOSE: Unexplained pain and stiffness after total knee arthroplasty (TKA) often result from mismatch between implant geometry and knee morphology, which depends on patient size, sex, and ethnicity. This study aimed to determine whether size, sex, or ethnicity are independently associated with distal femoral morphology in healthy Caucasian and Asian knees, and to compare anatomic ratios to those of commercially available TKA implants. METHODS: Two series of computed tomography (CT) angiograms from France (264 knees) and China (259 knees) were used to digitize osteometric landmarks at the level of the femoral epicondyles, to measure anteroposterior (AP) and mediolateral (ML) dimensions at the anterior, posterior, medial, and lateral zones...

PURPOSE: Total knee arthroplasty (TKA) designs continuously evolve with the aim of improving patient outcomes. The purpose of the current study was to compare clinical and patient-reported outcome (PRO) results of a new TKA implant to its predecessor. The hypothesis of this study was that joint awareness and range of motion (ROM) of the newer design would be better than the classic design. METHODS: One hundred patients undergoing TKA using the newer design (Attune® ) were matched by age and gender to 200 patients with the classic design (LCS® )...

PURPOSE: To assess mid-term survivorship of meniscal allograft transplantation (MAT) and determine the effect that pre-operative meniscal sizing has upon functional outcome and mechanical survivorship. METHODS: A prospectively collected database of patients receiving MAT from 2001 to 2017 was analysed. Data include demographics; sizing measurements, complications, further surgery, and patient-reported outcome measures (PROMs). Allografts were fresh frozen, non-irradiated, and sized using the Pollard technique...

PURPOSE: Posterior capsular contracture is a potential consequence of osteoarthritis, post-traumatic arthritis, and surgical procedures of the knee. Many patients who undergo TKA will be found to have some degree of flexion contracture intraoperatively, which necessitates posterior capsular release. There is no information in the literature about the safety of posterior capsular release done during TKA. The present cadaveric study investigates the safety of posterior capsular release during TKA...

PURPOSE: Most elbow dislocations can be treated conservatively, with surgery indicated in special circumstances. Surgical options, apart from fracture fixation, range from repair or reconstruction of the damaged ligaments to static external fixation, usually entailing either a long period of immobilization followed by carefully monitored initiation of movement or dynamic external fixation. In general, no consensus regarding surgical treatment has been reached. A new method of open ligament repair and augmentation of the lateral ulnar collateral ligament using a non-absorbable suture tape in cases of acute and subacute elbow instability following dislocations has been described here, which allows an early, brace-free initiation of the full range of motion...

PURPOSE: To compare the total number of sick-leave days caused by the knee injury from the day of injury and over the first year between acute (within 8 days) and delayed (6-10 weeks) anterior cruciate ligament reconstruction (ACLR) and also assess other clinical outcomes during this period. METHODS: Seventy patients with an acute ACL injury and Tegner level of 6 or more were randomized to acute (within 8 days) or delayed (after 6-10 weeks) ACLR. Patient-reported outcomes; objective IKDC and manual stability measurements were assessed at 6 and 12 months...

PURPOSE: Unicompartmental knee arthroplasty (UKA) is effective for treating degenerative joint disease in a single compartment. Robotic-arm-assisted arthroplasty (RAA) has gained popularity and has theoretical benefits of improved outcomes over conventional (CONV) UKA due to the technical precision of bone preparation. This study compares the short-term clinical outcomes, including survivorship and patient-reported functional outcomes, for a series of medial UKAs performed with RAA and CONV...

PURPOSE: With the introduction of the Attune Knee System (DePuy) in March 2013, a new polyethylene formulation incorporating anti-oxidants was used. Although several in vitro studies have demonstrated the positive effects of antioxidants on UHMWPE, no retrieval study has looked at polyethylene damage of this system yet. It was the aim of this study to investigate the in vivo performance of this new design, by comparing it with its predecessors in retrieval analysis. METHODS: 24 PFC (18 fixed bearing and 6 rotating platform designs) and 17 Attune (8 fixed bearing and 9 rotating platform designs) implants were retrieved...

PURPOSE: The purpose of this prospective, randomized, double-blinded, placebo-controlled study was to determine if pregabalin, when given perioperatively in addition to patient-controlled analgesia morphine, paracetamol and etoricoxib, is effective in reducing morphine requirements and moderating pain scores after primary total knee arthroplasty. We hypothesize that there would be no difference in postoperative opioid requirements, postoperative pain scores, and functional scores with the use of perioperative pregabalin...

PURPOSE: Traditionally, MRI has not been used to predict meniscus tear reparability. An attempt has been made in this study to predict meniscal reparability using MRI, and a new scoring system to help with the same has been developed and tested. METHODS: Thirty repaired menisci were compared with equal number of meniscectomy cases retrospectively. Various clinical and radiological (radiographs and MRI) characteristics like chronicity of tear, pattern of tear, etc, were tabulated...

PURPOSE: Rates for arthroscopic surgery for femoroacetabular impingement (FAI) are rising and there is growing concern related to the effectiveness and costs associated with this treatment. There is a general lack of consensus as to the criteria for surgical selection of patients. The purpose of this study was to determine whether patient outcome following arthroscopic surgery for FAI could be predicted based on the size and location of deformity. The specific questions were: (1) what is the morphology of FAI in terms of size and location of deformity in a cohort of patients selected for surgery? (2) Do morphological factors predict postoperative improvement in hip scores? (3) Do morphological factors predict preoperative hip scores? (4) Are there clusters of morphological factors which explain postsurgical improvement in hip scores? MATERIALS AND METHODS: Computer tomography (CT) surgical plans of 90 hips in 79 patients who had undergone primary hip arthroscopy for FAI were retrospectively reviewed...
