BACKGROUND: To determine effects of allogeneic human chondrocytes expressing TGF-β1 (TG-C) on structural progression of MRI features of knee osteoarthritis over a 1 year period. METHODS: This phase II randomized controlled trial of TG-C included patients with moderate to advanced osteoarthritis. Patients were randomized to receive an intraarticular 3:1 mixture of non-transduced allogeneic human chondrocytes and TG-C or placebo. 3 T MRI was acquired for all patients at baseline and follow-up (3, 6 and 12 months)...

Arborescent lipoma is an unusual intra-articular lesion that typically develops in the knee and has to be evoked before chronic effusion. It corresponds to hyperplasia of mature fatty tissue and hypertrophy of synovial villi, developing within a joint. The reference treatment is synovectomy by arthrotomy. The rare forms localized to the anterior compartment of the knee can benefit from an arthroscopic synovectomy. The authors report a case of arborescent knee lipoma in a 47-year-old patient who received arthroscopic synoviectomy...

Extensor mechanism complications involving the patella frequently result in total knee arthroplasty (TKA) failure. Postoperative patellar dislocation may be caused by soft tissue imbalance, improper sizing, and position of the prosthesis. This report describes a case of revision TKA requiring several rounds of soft tissue releases in an effort to treat the patient's chronic patellar dislocation. In the process, a novel surgical approach was developed for the surgical management of refractory chronic patellar dislocations...

BACKGROUND: Preoperative progressive resistance training (PRT) is controversial in patients scheduled for total knee arthroplasty (TKA), because of the concern that it may exacerbate knee joint pain and effusion. OBJECTIVE: To examine if preoperative PRT initiated 5 weeks prior to TKA would 1) exacerbate pain and knee effusion, 2) allow a progressively increased training load throughout the training period that would subsequently increase muscle strength. DESIGN: Secondary analyses from a randomized controlled trial...

Purpose  After total knee arthroplasty (TKA), pain and swelling, especially in older and less cooperative patients, can limit the retrieval of a good range of motion and muscle tone and consequently the achievement of an optimal function outcome. A high-tech knee pad made of metal fibers emitting infrared energy was used in a group of patients undergoing TKA to assess its efficacy in the postoperative period with respect to a group with a placebo. Methods  Twelve patients used knee pads after surgery for 3 weeks and were evaluated using visual analog scale (VAS), Knee Society Rating Score, Cincinnati Knee Rating Score, and painkillers at specific timings...

Song Yang, Tang Qi-Heng, Zhou Yi-Xin
BACKGROUND: This study aimed to compare the biomechanical strength and permeability of barbed vs traditional suture for closure of the porcine knee joint. METHODS: This study used Duroc pig knee joints. For each specimen, a 5-cm medial parapatellar arthrotomy was performed with the knee at 30° of flexion. We closed the arthrotomy wound using barbed suture (size 1/0 V-Loc 180) or traditional suture (size 1/0 PDS II). Specimens were divided into a PDS II (n = 9) and a V-Loc group (n = 9) for biomechanical testing, and a PDS II (n = 9) and a V-Loc group (n = 9) for permeability testing...

AIMS: Patients with flexion instability after total knee arthroplasty (TKA) often present with a recurrent effusion, which may be a haemarthrosis. While the radiographic factors contributing to flexion instability have been elucidated, the clinical diagnosis remains challenging. Our aim, in this study, was to determine the mean white cell count and differential profile in pre-operative aspirations of synovial fluid in a consecutive series of patients undergoing revision TKA for flexion instability...

INTRODUCTION: We conducted a retrospective study in patients with minimal or no radiographically evident knee osteoarthritis to determine whether presenting signs and symptoms were predictive of knee pathology that was evident on MRI and could be treated with nonarthroplasty knee surgery or could alter nonsurgical treatment. METHODS: We reviewed records of patients for whom sports medicine orthopaedic surgeons had ordered an MRI of the knee. Univariate analysis identified factors that were associated with positive MRI findings (eg, surgically treatable lesion, meniscal tear) or a finding that could alter treatment...

BACKGROUND: Spontaneous osteonecrosis of the knee (SONK) is a clinical entity identified by acute knee pain usually associated with joint effusion, with radiographic findings of a radiolucent defect on the weightbearing area of the femoral condyle. Conservative treatment is initially undertaken; however, surgical procedures are often necessary. Historically, surgical options have included core decompression, cartilage repair, high tibial osteotomy, or joint arthroplasty. Few studies in the literature have reported the use of fresh osteochondral allograft (OCA) for the treatment of SONK lesions...

INTRODUCTION: Synovial hemangioma is a rare condition with <200 published case reports in world literature and is frequently misdiagnosed, leading to diagnostic delay of many years. This delay is even more significant if the patient comes from a rural background with a dearth of medical facilities in the area. This case had a lag of nearly 20 years from the time of onset of symptoms and the required management which is the maximum reported for any synovial hemangioma since most of them have been found and treated in adolescents...

OBJECTIVE: The purpose of this study was to determine the validity of infrapatellar fat pad (IPFP) opacity grading based on lateral knee radiography for assessing knee synovitis using correlation with contrast-enhanced (CE) MRI. MATERIALS AND METHODS: Retrospective reviews of radiographs and CE knee MR images from 79 patients were independently performed by two radiologists. They evaluated IPFP opacity alteration (IPFPCR) and joint effusion grades on lateral knee conventional radiographs, IPFP signal intensity alteration (IPFPMR) and joint effusion grades on CE MR images, and synovitis (SYNMR) grade in nine divided regions, three compartments (parapatellar, periligamentous, perimeniscal), and the whole knee on CE MR images...

BACKGROUND: Diffusion-weighted MRI has been proposed as a new technique for imaging synovitis without intravenous contrast application. We investigated diagnostic utility of multi-shot readout-segmented diffusion-weighted MRI (multi-shot DWI) for synovial imaging of the knee joint in patients with juvenile idiopathic arthritis (JIA). METHODS: Thirty-two consecutive patients with confirmed or suspected JIA (21 girls, median age 13 years) underwent routine 1.5 T MRI with contrast-enhanced T1w imaging (contrast-enhanced MRI) and with multi-shot DWI (RESOLVE, b-values 0-50 and 800 s/mm(2))...

OBJECTIVES: To identify whether a physical examination for patello-femoral pain (PFP) is related to ultrasonography findings at the knee, and to identify possible factors related to PFP in young dancers. METHODS: Sixty-seven young female dancers (7th grade, aged 12.8±0.5) from three schools with identical special dance programs were included in the study. All the dancers were interviewed for demographic details, dance background, and training intensity; were evaluated for anthropometric measurements; underwent physical examination of both knees for PFP and for knee range of motion (ROM); and, had ultrasonography assessment for pathologies and of anatomical parts of their knees...

REVIEW
Tuhina Neogi
Osteoarthritis (OA) is the most common form of arthritis, with knee OA itself being among the most common conditions and a leading cause of disability among older adults worldwide. Pain is a key symptom in the decision to seek medical attention, yet available therapies for managing OA are limited with only minimal or moderate efficacy. Current approaches to pain management in OA have been rather non-specific, limited to acetaminophen or NSAIDs primarily, without targeting underlying structural lesions that may be contributing to pain in OA...

Injuries occurring in the remote environment present particular challenges to healthcare professionals, and decisions need to be carefully made on an individual basis. This report describes the successful management of a patella fracture sustained on the Subantarctic island of South Georgia. A 36-year-old boating officer presented to the island surgery after sustaining an isolated closed injury to his left knee. On physical examination there was a large effusion palpable within the joint, and on subsequent radiography an undisplaced transverse fracture of the patella was apparent...

Acute non-traumatic swelling of the knee is a common clinical challenge. The reason for the swelling has to be explored in order to give the correct treatment. This article gives an overview of possible diagnoses and suggests an algorithm for an approach to non-traumatic knee arthritis. Fundamental in the examination is a thorough patient anamnesis, which will help to differentiate between inflammatory and non-inflammatory arthritis. If there is not an obvious degenerative reason for the knee effusion, a joint aspiration followed by synovial fluid white cell count (WCC), microscopy and/or culture will add valuable information...
