We present a case of a 19-year-old woman with a forced hyperextension trauma of the knee causing a posteromedial fracture, a medial meniscus root tear and rupture of the posterior cruciate ligament. The posteromedial fracture of the tibial plateau was treated operatively with open reduction and internal fixation. Anatomical reconstruction was achieved. Postoperative treatment included unlimited flexion and minimal weight bearing. After 3 months, the patient had minimal pain after weight bearing and returned to preoperative range of motion...

Lumbar disk herniation is common. Because of the posterior longitudinal ligament, migration usually occurs into the ventral epidural space. Rarely, fragments migrate into the dorsal epidural space. A 57-year-old man presented with lower back pain and weakness on right hip flexion and right knee flexion. He had lower back pain 1 day previously and received a transforaminal epidural block at a local hospital. The next day, he reported weakness of the right lower extremity. Lumbar spine magnetic resonance imaging revealed a dorsal epidural lesion with compression of the thecal sac at L2-3...

INTRODUCTION: Medial meniscus posterior root tear (MMPRT) leads to abnormal biomechanics of the knee by inducing the medial meniscus extrusion (MME). However, a time-dependent increase of the MME isnot fully elucidated in patients suffering from the acute MMPRT. The aim of this study was to investigate the relationships among disease duration of the MMPRT andseverity of the MME. We hypothesized that MME measurement correlates with disease duration after a sudden onset ofthe minor traumaticMMPRT during the short-term follow-up period...

BACKGROUND AND OBJECTIVES: The popliteal nerve plexus contributes to afferent knee-pain conduction. It is mainly formed by genicular branches from the posterior obturator and the tibial nerves, innervating the intra-articular and posterior knee region. A subinguinal obturator nerve block alleviates pain after total knee arthroplasty. Reduced hip adductor motor function could be avoided by a posterior obturator nerve block inside the popliteal fossa. The aim of this study was to evaluate the spread of dye after a distal adductor canal (AC) injection to the popliteal fossa and coloring of the popliteal plexus and the genicular branch of the posterior obturator nerve by dissection...

INTRODUCTION: Painful patellar clunk and crepitance (PCC) is a known complication of total knee arthroplasty (TKA) with posterior-stabilized designs. Arthroscopic management of PCC has been proposed as a treatment option for PCC. METHODS: We reviewed all cases of PCC from a consecutive single-surgeon series using a specific posterior stabilized (PS) design treated with arthroscopy for PCC. In a series of 1,488 TKA cases, forty-six patients (3.1%) were identified to have clinical signs and symptoms of PCC during post-operative clinic follow-up...

OBJECTIVES: Morphological features of the distal femur and proximal tibia associated with cartilage degeneration are unknown. This study aimed to elucidate local anatomical parameters of the knee which correlate with articular cartilage degeneration using MRI T1ρ mapping. METHODS: This study involved 200 subjects with knee pain (mean age, 48.7 years; range, 14-80 years) with no severe osteoarthritic changes on plain X-ray. T1ρ values were measured in the regions of interest on the surface layer of the cartilage on mid-coronal images of the femorotibial joint...

INTRODUCTION: The posterior portion of the knee joint, which includes the tibial attachment of the posterior cruciate ligament and the posterior horn of the menisci, has been called a "blind spot" because it is difficult to observe this area under arthroscopy through standard anterior portals. Posteromedial, posterolateral, and posterior transseptal portals have been developed for visualization and instrumentation of the posteromedial and posterolateral compartments of the knee joint...

Therapeutic exercises in osteoarthritis (OA) are therapeutic approach with proven efficacy. On the other hand, the different disease form, the lack of established consensus and system for patient education limit the widespread use of therapeutic exercises in clinical practice. The mechanisms of action of therapeutic exercise in OA include the following components e. g., neuromuscular (improvement of proprioception, muscle strength and joint stability), intra-articular (prevention of cartilage degeneration, antiinflammatory effect, improvement of the quality of the joint fluid), periarticular, general health with reduction of cardiovascular risk and psychological components...

BACKGROUND: Pain following total knee arthroplasty (TKA) is often severe and can inhibit rehabilitation. Motor-sparing analgesic techniques such as periarticular infiltrations and adductor canal blocks have been popularized for knee analgesia since they preserve motor strength and permit early mobilization. Our primary objective was to compare the duration of analgesia from motor-sparing blocks with that of a standard periarticular infiltration. We used the time to first rescue analgesia as the end point...

BACKGROUND: Osteochondral lesions of the tibial plafond (OLTPs) can lead to chronic ankle pain and disability. It is not known how limited ankle motion or joint distraction affects arthroscopic accessibility of these lesions. The purpose of this study was to determine the effects of different fixed flexion angles and distraction on accessibility of the distal tibial articular surface during anterior and posterior arthroscopy. METHODS: Fourteen below-knee cadaver specimens underwent anterior and posterior ankle arthroscopy using a 30-degree 2...

RATIONALE: High tibial osteotomy (HTO) has been used widely for medial compartment knee osteoarthritis to correct the deformity and relieve symptoms, especially in young patients who are willing to maintain the high activity level. However, the change of bone morphology, ligament imbalance, limb malalignment, and other complications may influence the short-term outcomes of HTO. Some cases may even require conversion to TKA shortly after HTO because of the loss of correction or pain due to accelerated osteoarthritis...

BACKGROUND: Although femoral nerve block provides satisfactory analgesia after total knee arthroplasty (TKA), residual posterior knee pain may decrease patient satisfaction. We conducted a randomized controlled trial to clarify the efficacy of the sciatic nerve block (SNB) and local infiltration of analgesia with steroid (LIA) regarding postoperative analgesia after TKA, when administrated in addition to femoral nerve block (FNB). METHODS: Seventy-eight patients were randomly allocated to the two groups: concomitant administration of FNB and SNB or FNB and LIA...
