X-ray film showed osteolytic destruction of the distal femur, with periosteum reaction and soft tissue mass. Physical examination on admission identified: claudication, distal left femur palpable, hard mass, local tenderness and limited (0° - 95°) left knee flexion. Patient 1 is a 66 years old female who has been complaining of swelling and pain in the left thigh for more than 2 years, which have been aggravating in the 2 months before hospital admission on June 16, 2016. We performed a retrospective analysis in order to explore the diagnostic features of the disease, total extra-articular knee joint resection technique and clinical effects of the excision. The present study presents data of 4 patients with malignant tumors invading the knee cavity admitted to the department of orthopedics. The evaluation of bone tumors requires a thorough history and physical examination in conjunction with proper utilization and diagnostic understanding of additional tests and procedures. This procedure is complicated and requires very good knowledge of anatomy around the knee joint structures. When a malignant tumor around the knee joint invades the knee cavity, block resection is required to treat the tumor outside the knee joint. Also, in some cases, tumors were found in the intercondylar notch invading the cruciate ligament. in 16% of cases, the cancerous mass directly penetrates the articular cartilage and invades the articular cavity, while in 9% of cases the tumor grows around the articular cartilage, connect with the joint capsule and enters the joint cavity. The most common procedure for tumor resection Involves opening the joint capsule and reconstructing the affected segment. In rare cases, the malignant mass invades the knee joint cavity as a consequence of biopsy or surgery leading to accidental tumor spread, pathological fractures, invasion of the joint ligament or direct invasion of the joint. The probability that the tumor will invade the joint cavity is usually low and so in most cases, the swelling around the knee joint is reduced.
The main treatment for this type of cancer is limb salvage surgery, which involves total resection of the tumor followed by reconstruction of the knee structure. The area around the knee joint is a common site of malignant bone tumors.

Malignant tumor Knee joint Extra-articular resection Prosthesis implantation Case series No tumor recurrence or metastasis was detected, and no death occurred.Ĭonclusion: We identified 4 cases of malignant tumor involving the knee in which total and partial excision and reconstruction were performed. Quadriceps muscle strength was grade 4 in two cases and grade 5 in the other two cases. At the last follow-up, the knee flexion angle range for the 4 patients was 95°, 100°, 100°, and 110°, respectively, and the delay of knee extension was 5°, 10°, 10° and 5°, respectively tissue tumor association scores were 53%, 77%, 80%, and 83%. Knee function was recovered satisfactorily after 24-37 months of follow-up. Results: The interventions were successfully completed without vascular and nerve injury, but in 1 case, the wound healing was delayed. All 4 patients underwent total knee joint tumor resection with prosthesis replacement. The diagnosis was confirmed by histopathology. We identified 2 males and 2 females with knee joint malignancy, aged 38 ~76 years. Patients admitted to the hospital between June 2016 to March 2019. Methods: A retrospective analysis was conducted on 4 cases of knee joint problems. Malignant bone tumors are rare conditions that may be encountered by non-oncologic surgeons only a few times in their careers, but a delay in diagnosis or a misinterpretation of data can have limb and life-threatening consequences.
