Finally, 42 of 60 patients (70%) had an anterior cruciate ligament tear and 28 (45%) had a medial meniscus tear. In conclusion, MRI appears a very useful tool in the detection and characterization of the different types of occult bone and/or cartilage injuries of the knee in the patients with previous acute trauma. Moreover, the correct and early diagnos …

The prevalence of knee injuries ipsilateral to tibial shaft fractures and their impact on clinical outcome.

OBJECTIVE: The purpose of this prospective study was to examine the prevalence of occult knee injuries in patients with ipsilateral tibial shaft fractures and determine their impact on clinical outcome. MATERIALS AND METHODS: Preoperative knee MRI examination was performed in 41 patients (42 knees) with isolated tibial shaft fractures. Menisci, cruciate ligaments, collateral ligaments, extensor mechanism, osteochondral lesions, bone contusions and knee effusion were evaluated. All patients were treated with reamed and locked intra-medullary tibial nailing without an additional surgical proced

[Value of imaging in posterolateral corner injuries of the knee].

Lesions of the posterolateral corner are usually post-traumatic in etiology. They are most frequently associated with tear of the ACL and/or PCL. When unrecognized, they may lead to short-term failure of cruciate ligament reconstruction or long-term knee joint degeneration. Early detection of such lesions, especially in the preoperative period, is important since more severe injuries usually require dedicated early surgical management. The anatomy of the posterolateral corner will be reviewed and the normal and abnormal imaging features on MRI and US will be illustrated. The main clinical and

Older age, higher BMI, female sex and meniscal repair are predictors of inferior patient-reported outcomes 1 year after ACL reconstruction.

PURPOSE: To identify predictors of inferior patient-reported outcomes (PROs) 1 year after anterior cruciate ligament reconstruction (ACLR) and to examine whether these predictors differ by sex. We hypothesised that older age, female sex, and meniscectomy are associated with inferior PROs. METHODS: We conducted a prospective cohort study involving 733 patients (396 males and 337 females) who underwent ACLR using autologous hamstring tendons. Participants were enroled in the Hiroshima Clinical ACL Research Project. Pre-operative assessments included demographic data, injury history, and scores

The results of meniscal allograft transplantation surgery: what is success?

BACKGROUND: Meniscal allograft transplantation (MAT) may improve symptoms and function, and may limit premature knee degeneration in patients with symptomatic meniscal loss. The aim of this retrospective study was to examine patient outcomes after MAT and to explore the different potential definitions of 'success' and 'failure'. METHODS: Sixty patients who underwent MAT between 2008 and 2014, aged 18-50 were identified. Six validated outcome measures for knee pathologies, patient satisfaction and return to sport were incorporated into a questionnaire. Surgical failure (removal of most/all the

Nerve growth factor inhibition with tanezumab influences weight-bearing and subsequent cartilage damage in the rat medial meniscal tear model.

OBJECTIVE: To investigate whether the effects of nerve growth factor (NGF) inhibition with tanezumab on rats with medial meniscal tear (MMT) effectively model rapidly progressive osteoarthritis (RPOA) observed in clinical trials. METHODS: Male Lewis rats underwent MMT surgery and were treated weekly with tanezumab (0.1, 1 or 10 mg/kg), isotype control or vehicle for 7, 14 or 28 days. Gait deficiency was measured to assess weight-bearing on the operated limb. Joint damage was assessed via histopathology. A second arm, delayed onset of treatment (starting 3-8 weeks after MMT surgery) was used t

The pediatric knee: current concepts in sports medicine.

As the popularity and intensity of children's athletics have increased, so has the risk for knee injuries. Fractures of the tibial eminence may be treated operatively or nonoperatively depending on fracture classification, but arthrofibrosis is a potentially significant complication. Anterior cruciate ligament rupture presents treatment challenges as regards the optimal timing and method of reconstruction. A number of novel reconstructive techniques have been developed to minimize risks to the physes in this population. Recent studies have focused on the prognosis, surgical indications, and op

Knee injuries related to sports in young adult males during military service - incidence and risk factors.

The population-based incidence and risk factors for knee injuries in young adults were assessed in Finnish male conscripts performing their compulsory military service (n = 128,584). The main outcome variables were (1) hospitalization due to knee injuries overall and (2) hospitalization due to knee disorders as categorized into specific International Classification of Diseases, tenth revision diagnoses (cruciate and collateral ligament tears, meniscal tears, traumatic chondral lesions, and patellar dislocations). Person-time injury-incidence rates were calculated by dividing the number of pers

Osteonecrosis of the tibial plateau: magnetic resonance imaging appearances with quantitation of lesion size and evidence of a pathogenesis of meniscal injury.

PURPOSE: To determine the magnetic resonance (MR) imaging appearances of osteonecrosis of the tibial plateau and perform quantitative analysis of the extent of the necrotic area. MATERIALS AND METHODS: Twenty-eight patients (34 knees) with osteonecrosis were retrospectively evaluated using MR imaging and other modalities where available. A computerized image analysis program that allowed quantification of the lesion size was used to obtain measurements of the extent of involvement, which were then incorporated into each stage of the disease. RESULTS: The MR imaging findings of osteonecrosis

[MR imaging of the knee].

Since its introduction into clinical use, magnetic resonance imaging (MRI) has become well established in the diagnosis of injuries of the knee joint and has replaced diagnostic arthroscopy as the primary evaluation method. Traumatic lesions of the ligaments, menisci, and articular surfaces are common injuries that can be confidently detected using MRI. This article reviews the basic principles of the examination technique of the knee, the normal MRI anatomy of the internal joint structures, and the typical findings in injuries of the cruciate ligaments, collateral ligaments, and mensci, in tr

Anterior cruciate ligament allograft reconstruction in the skeletally immature athlete.

The purpose of this study was to evaluate anterior cruciate ligament allograft reconstruction in skeletally immature athletes. Eight patients (mean age, 13 years, 6 months; range, 10 to 15 years) with radiographic documentation of open growth plates had anterior cruciate ligament repair and reconstruction with fascia lata or Achilles tendon allograft tissue. A 7-mm graft was centrally placed across the tibial physes and in an over-the-top position on the femur. All patients returned for followup a mean of 58 months (range, 22 to 94) postoperatively. All had an immediate knee motion and rehabil

Outcomes and Complications of Tibial Tubercle Fractures in Pediatric Patients: A Systematic Review of the Literature.

BACKGROUND: Systematic review of the literature was done to determine (1) the frequency and type of associated injuries, (2) frequency of concomitant Osgood-Schlatter disease, (3) methods of treatment, (4) functional and radiologic outcomes according to fracture type, and (5) complications of tibial tubercle fractures in pediatric patients. METHODS: A systematic review of the English literature from 1970 to 2013 included 23 eligible articles reporting 336 fractures with a mean follow-up of 33.56 months (range, 5.7 to 115 mo). Fractures were classified by a comprehensive system that included c

Outcomes After Anterior Cruciate Ligament Reconstruction Using the Norwegian Knee Ligament Registry of 4691 Patients: How Does Meniscal Repair or Resection Affect Short-term Outcomes?

BACKGROUND: While the effects of concurrent meniscal resection and anterior cruciate ligament reconstruction (ACLR) are known to decrease patient outcomes and increase the rate of osteoarthritis over the long term, overall short-term patient functional outcomes in a large cohort of patients are not well known. PURPOSE/HYPOTHESIS: The purpose of this study was to compare the preoperative and 2-year postoperative Knee Injury and Osteoarthritis Outcome Score (KOOS) subscale scores after ACLR with and without meniscal injury. The hypothesis was that, in comparison with an isolated ACLR, patients

Diagnostic efficacy in knee MRI comparing conventional technique and multiplanar reconstruction with one-millimeter FSE PDW images.

BACKGROUND: Magnetic resonance (MR) imaging has proved to be an excellent tool in diagnosing injuries of the cruciate ligaments and menisci. However, multiple planes and sometimes optimal oblique or double-oblique scan planes are needed due to the variability in the positioning of important structures, which means there is a lower throughput and longer scanning time. PURPOSE: To compare the performance of a 1-mm-thickness fast spin-echo (FSE) proton-density-weighted (PDW) MR imaging technique with multiplanar reconstruction (MPR) in diagnosing tears of the menisci and cruciate ligaments with

Extensor mechanism disruption after contralateral middle third patellar tendon harvest for anterior cruciate ligament revision reconstruction.

The contralateral central third patellar tendon autograft is a reliable graft choice for revision, and recently, for primary reconstruction of the anterior cruciate ligament (ACL). We report 2 complications including a lateral third tibial tuberosity fracture and a distal patellar tendon avulsion with contralateral patellar tendon autograft with disruption of the extensor mechanism of the donor knee. A patient sustained a lateral tibial tuberosity fracture of the donor knee and underwent open reduction and internal fixation. At 1-year follow-up, she had no extensor lag and full range of motion
