A comparison of clinical efficacy between different surgical approaches for popliteal cyst

Background A popliteal cyst is a benign swelling with synovial fluid located behind the knee joint. Popliteal cysts are often asymptomatic; however, symptomatic cysts may cause pain and may need surgery interventions. Here, we performed a perspective study to compare the clinical efficacy of different surgical approaches, including traditional open excision and advanced arthroscopic treatment.
