Introduction And Importance: Hoffa's fat pad (HFP), also known as infrapatellar fat pad, is one of the three fat pads in the knee. Ganglion cyst (GC) rarely arises from HFP which presents knee pain and swelling.
Case Presentation: A 43-year-old female presented with left knee pain for 1 year and swelling in her left knee for 6 months.

Popliteal cysts, also termed Baker's cysts, are clinically common cystic lesions in the popliteal fossa. Typically, the contents of a ruptured cyst tend to spread into the myofascial interfaces in any direction, most commonly inferomedially or into a palpable superficial position. However, to our knowledge, reports of Baker's cysts dissecting into the deep intermuscular septum of the lower calf are extremely rare.

Microfracture can induce a less favorable biologic response that includes formation of type I fibrocartilage and development of subchondral cystic changes or sclerosis. Thus, chondral graft options that restore native type II hyaline cartilage are favored.

Objective: Bone Marrow Lesions (BMLs) are areas in bone with high fluid signal on MRI associated with painful and progressive OA. While cartilage near BMLs in the knee has been shown to be degenerated, this relationship has not been investigated in the hip.
Research Question: is T1Gd lower in areas of cartilage overlying BMLs in the hip?
Design: 128 participants were recruited from a population-based study of hip pain in 20-49-year-olds.

Unlabelled: Certain types of popliteal cysts do not possess the common pathophysiology of Baker's cysts, such as location or the presence of a one-way valve lesion. The traditional arthroscopic approach and excision of such atypical popliteal cysts are difficult because they do not communicate with the knee joint, especially when located behind the popliteal neurovascular structure. In this case report, we introduce a direct posterior endoscopic technique for the excision of atypical popliteal cysts when accessing them through the traditional arthroscopic approach is unfeasible.

Brown tumor of the knee is a focal benign cystic lesion of bone. The etiopathogenesis of brown tumor is believed to be abnormal bone metabolism in patients with hyperparathyroidism. We present a case of a 32-year-old male with recurrent knee pain, weakness of the lower limb and a nodular mass on left inferior lobe of thyroid.

Frequently, parameniscal cysts are so small that patients do not notice them, being asymptomatic. However, they can grow and exceed 2 centimeters in diameter, causing pain and alarm due to the slow growing mass.

The cause of knee osteoarthritis (OA) and knee pain associated with OA is not well understood. Periarticular cystic lesions and bursae around the knee are among the most common morphologic features identified on MRI in the setting of OA. Despite widespread association of these lesions with knee OA and their inclusion in semiquantitative MRI scoring assessment systems for knee OA, the role that these lesions play in the development of knee pain and OA remains uncertain.

Background: One of the causes of foot drop is compression of the common peroneal nerve caused by space-occupying lesions such as a synovial cyst or a ganglion cyst. Most previous reports have involved compressive common peroneal neuropathy by intraneural ganglion cysts and synovial cysts. Compression of the peroneal nerve by extraneural ganglion cysts is rare.

A mucoid degeneration of the anterior cruciate ligament (ACL) is regarded as a degenerative change in the ligament, which is clinically presented with pain on full extension or flexion. Regarding morphological factors, it has been reported that an increased posterior tibial slope can be a cause of ACL degeneration secondary to the repetitive overload. The increase in the tibial slope is among the potential problems after medial opening wedge high tibial osteotomy (OWHTO).

Background: Angiofibroma of soft tissue (AFST) is a rare mesenchymal neoplasm of fibroblastic differentiation. Due to its diverse morphology and the lack of specific immunohistochemistry (IHC) markers, AFST could elicit a broad range of differential diagnosis. Several studies have disclosed in AFST recurrent gene fusions involving , mainly fusion, providing a useful approach to diagnosing this lesion.

Introduction: Chronic osteomyelitis is difficult to cure definitively, because local areas are often covered with sequestrum and scar tissues with a poor blood flow; these may render systemic antibiotic administration ineffective. We present a case of chronic osteomyelitis that was successfully treated with continuous local antibiotic perfusion (CLAP) through an intramedullary antibiotic perfusion (iMAP) pin.
Case Presentation: A 65-year-old man who suffered an episode of the right femoral osteomyelitis at the age of 15 years experienced a relapse at the age of 63 years.

Chondral injuries of the femoral head and their possible progression to osteoarthritis is well known. Regarding focal lesions in young patients, microfracturing or autologous chondrocyte implantation (ACI) are the most frequent used techniques to address them. Although ACI provides the better tissue quality, it is a two-step procedure and needs a lot of resources.

Background: Studies have reported favorable clinical outcomes after osteochondral allograft (OCA) transplantation to treat osteochondral defects and have demonstrated that healing of the osseous component may be critical to outcomes. However, there is currently no consensus on the optimal modality to evaluate osseous healing.
Purpose: To define parameters for OCA healing using computed tomography (CT) and to investigate whether osseous healing identified using CT is correlated with improved pain and function on patient-reported outcomes (PROs) collected closest in time to the postoperative CT scan and at final follow-up.
Osteochondral lesions of the talus occur with relatively frequency, often as the sequelae of benign ankle sprains, and are only surpassed by the knee and elbow as more common locations. While microfracture of the talus is the most common first-line surgical treatment performed at the time of ankle arthroscopy, marrow stimulation alone results in fibrocartilaginous repair tissue rather than true hyaline-like articular cartilage. In addition, the benefits of bone marrow stimulation for the treatment of large (>150 mm), deep (>7 mm), or cystic lesions is limited.

Bone lesion of the proximal tibia are common findings; depending on the site, age of the patient and symptoms a carefull differential diagnosis must be carried out. We present the case of a 60 years old active patient presenting at our clinic with atraumatic knee pain. X-Rays performed revealed an osteolitic lesion of the medial tibial condyle; MRI highlighted a lobulated cystic lesion of the medial tibial condyle without evidence of interruption of the suchondral bone.

Introduction: The ganglion cysts are benign fluid-filled sacs, which often arise from a tendon sheath or a joint capsule. Their origin from the fat pad of the knee is rare. Several studies have described intra-articular ganglion cysts in detail; however, extra-articular soft-tissue ganglion cysts have been reported sparingly.

Parameniscal cysts are usually small cystic lesions, less than 2 cm in size, found along the meniscal periphery. They are rarely associated with extra-articular palpable mass. Magnetic resonance imaging is the diagnostic method of choice; giant meniscal cysts (>5 cm at its greatest diameter) are very rare, with few cases described in the literature.
