Arthroscopic resection of an osteochondroma of the knee (original) (raw)

Arthroscopic Marginal Excision of Osteochondroma around the Knee: A Case Series

https://www.ijhsr.org/IJHSR\_Vol.12\_Issue.5\_May2022/IJHSR-Abstract.018.html, 2022

Osteosarcoma is the most common bone tumor. These tumors are usually asymptomatic and show clinical symptoms as a result of trauma and pressure from the surrounding muscles, joints, nerves, and blood vessels. Treatment from this tumor varies from patient to patient. In this case report, we describe 3 cases of osteochondroma around knee. The cases were boys 17 years old, 15 years old, and 38 years old patient. The diagnose was confirmed by imaging such as plain radiography and histology. All three patients were treated with arthroscopic marginal excision of knee.

Para-articular/extra-osseous osteochondroma of the knee

The Knee, 1999

An unusual case of osteochondroma arising in the soft tissues adjacent to the knee is presented. The controversy arises from the confusion of this mass with giant synovial chondromatosis or the more dangerous chondrosarcomas. Preoperatively, CT scans can demonstrate that these lesions are isolated to the soft tissues, and there is no connection to bone; this can be confirmed at surgery. Detailed histological analysis is important to rule out malignant changes. The distinction is important to avoid unnecessary aggression in surgery, as these are benign lesions with a good prognosis after local excision.

Endoscopic Resection of Symptomatic Osteochondroma of the Distal Femur

Clinical Orthopaedics and Related Research, 2007

The surgical risk and complication rates for an open excision of a benign osteochondroma have been reported as high as 13%. The advent of minimally invasive techniques allows a surgical resection with a smaller incision and a potential for less postoperative morbidity. We presumed endoscopic resection of symptomatic osteochondroma of the distal femur would decrease postoperative morbidity of open surgery and improve functional outcome. We performed endoscopic resection of a symptomatic osteochondroma in seven patients among 24 who had surgical excision. Preoperative studies include radiographs and computed tomography scans. At a mean followup of 33 months, patients were functionally evaluated according to the Lysholm score and the International Knee Documentation Committee scale. Four exostoses were located at the anterolateral femoral cortex, one at the trochlea, and two at the anteromedial cortex. Histologic diagnosis of an osteochondroma was confirmed in all cases. The average Lysholm score improved 22 points from a mean of 74 preoperatively to 96 postoperatively, and according to the International Knee Documentation Committee scale, all patients showed a normal knee. In 7 of 24 patients with a symptomatic osteochondroma of the distal femur close to the knee, we performed endoscopic resection with low morbidity and prompt functional recovery.

Treatment Strategy of Fractured Osteochondroma in the Young Athlete’s Knee

Journal of Clinical Medicine

Purpose: The main purpose of this study was to compare the clinical outcome of surgery versus observation in young athletes with fractured osteochondromas in the knee. The secondary aim was to evaluate displacement versus non-displacement fractures with regards to functional recovery. Methods: A retrospective analysis was performed in young athletes with fractures of osteochondromas in the knee. In the surgery group, resection of the osteochondromas was performed due to pain persisting at 4 weeks after injury. In contrast, patients with pain diminishing within 4 weeks after injury were observed without surgery. Displacement was defined as a gap widening of ≥1 mm between fragments, or translation of >50% of the distal fragment in relation to the proximal fragment. The time to return to the original sport was compared between groups. Results: The study sample was composed of 21 patients with a mean age of 12 years (range 9–16 years). There were 14 patients in the surgery group and ...

Para-articular Osteochondroma of the Knee

Arthroscopy: The Journal of Arthroscopic & Related Surgery, 2007

We report a case of para-articular chondroma located in the infrapatellar fat pad of the knee of a 42-year-old woman with a history of anterior knee pain and restricted range of motion. On clinical examination, a solid palpable mass in the infrapatellar region was detected. Radiography and computed tomography of the knee revealed the presence of 3 different "popcorn"-like gross calcifications within Hoffa's fat pad. Magnetic resonance imaging showed areas of signal intensity in Hoffa's fat pad that were consistent with calcific nodules surrounded by chondral tissue. During arthroscopy, a dense extrasynovial mass was discerned within Hoffa's fat pad. The mass was entirely removed through an open approach medial to the patellar tendon. Resection specimens consisted of 3 well-circumscribed nodules of 5 ϫ 2.5 ϫ 1.5, 2 ϫ 2 ϫ 1, and 1.5 ϫ 2 ϫ 1 cm, respectively. Grossly, these nodules were surrounded by adipose tissue and presented a thin fibrous membrane. Histologic examination showed that the nodules were composed of cartilaginous tissue surrounded by fibrous connective and adipose tissue with multifocal endochondral ossification. The precise pathogenetic mechanism of these tumors remains unknown, but cartilaginous metaplasia of articular and para-articular connective tissue seems to be the primary cause. Patients with these lesions are currently treated with the use of marginal resection or excision.

Management of Osteochondroma: A Case Series

Acta Scientific Clinical case Reports, 2023

Osteochondroma is a benign tumor of the bone that occurs during childhood or adolescence. It forms on the surface of bones near the growth plate and compose of bony portion with a cartilaginous cap. Asymptomatic growths are managed conservatively. Excision is done in cases of pain, discomfort or for cosmetic reasons. The aim was to conduct a review of cases of Osteochondroma managed at our institution. Between November 2015 and April 2016, 3 cases were managed in our facility, 2 of the patients were females (ages 9 and 10) while the third patient is a male, 30years. Duration of symptoms prior to presentation ranges from 2-9years. There was a case of multiple exostoses (both shoulders, ribs, and the distal tibia) while the remaining two have solitary exostosis (pelvis and distal radius). All patients were evaluated using plain radiographs and computed tomographic scan was done for the case located within the pelvis. The indication for excision ranges froma pain and discomfort to difficulty in ambulation. All patients had excision based on the indication at evaluation. Follow up period was 24 months. There were significant improvements in the symptoms after excision and there was no case of recurrence after excision. All patients were satisfied with the procedure. Excision of symptomatic cases of solitary or multiple exostoses is the mainstay of management of this benign bone tumour.

Patellar Osteochondroma: A Unique Presentation

The Israel Medical Association journal : IMAJ, 2018

B interruptions inside the cartilaginous component of the osteochondroma. A computerized tomography (CT) scan can depict the bony lesion in detail, the pathognomonic cortical and marrow continuity of the lesion and parent bone, as well as showing the presence of calcifications [4] [Figure 2A, 2B, 2C]. A review of the existing literature revealed three cases of patellar osteochondroma described in the last 5 decades. All were reported as benign lesions [5]. We describe a 47 year old healthy woman who presented with mild pain T he patella is an infrequent location for the onset of benign or malignant bone tumors [1]. Although the tumors are usually benign, they require special attention because the patella plays an irreplaceable biomechanical function in knee extension. Osteochondroma is the most common benign bone tumor. It occurs in 3% of the general population [2]. Osteochondroma appears in the physeal plate of long bones during childhood through endochondral ossification. It is th...

Accelerated para-articular osteochondroma formation within the knee: a case report

Cases Journal, 2008

Introduction: Intra-articular osteochondroma and acoustic neuroma are rare entities. Case presentation: We report the rare occurrence of a para-articular osteochondroma of the knee developing over short duration, 5 months, following minor injury. Conclusion: Predisposition to heterotrophic ossification after previous neurosurgery and a second acoustic neuroma may have accelerated the growth of this benign tumour. The development of these two rare entities suggests they may be associated.
