Background: The purpose of this study was to evaluate the efficacy of arthroscopic knee cavity internal drainage and cyst cavity debridement operation of popliteal cyst in knee osteoarthritis patients.
Methods: From August 2007 to March 2013, 58 knee osteoarthritis patients with popliteal cyst were treated with arthroscopic knee cavity internal drainage through posteromedial portal and popliteal cyst cavity debridement through superior posteromedial portal. In all patients, preoperative magnetic resonance imaging (MRI) was performed to detect combined intra-articular pathology and the communication between popliteal cyst and knee cavity. Clinical efficacy was evaluated through VAS score and Lysholm score.
Results: All patients had neither recurrence of popliteal cyst nor complaints of pain, swelling, or functional impairment at average 24 months follow-up after surgery. Postoperatively, VAS score was decreased significantly and Lysholm score was raised significantly comparing preoperatively.
Conclusion: Arthroscopic knee cavity internal drainage operation through posteromedial portal and popliteal cyst cavity debridement through superior posteromedial portal is an effective minimally invasive surgery method for the treatment of popliteal cyst without recurrence in knee osteoarthritis patients.

Popliteal cysts (PCs) are occasionally accompanied by knee osteoarthritis (OA) and varus malalignment. However, whether concomitant arthroscopic excision of PCs with medial open-wedge high tibial osteotomy (MOWHTO) improves the osteoarthritic environment remains unclear. Therefore, this study assessed serial changes in C-size, medial meniscus extrusion (MME), and cartilage status for up to 2 years following an MOWHTO.

The popliteal cyst is a common condition that causes disturbing symptoms. Several arthroscopic techniques are combined to treat the enlargement of communication and decompose the cyst wall, aiming to reduce recurrence. We propose a technique that involves resecting the posteromedial valve mechanism and excising the cyst wall through a 2-posteromedial portal approach.

Introduction: The posteromedial compartment of the knee houses several important anatomical structures, including the oblique popliteal ligament (OPL), an accessory insertion tendon of the semimembranosus muscle. Popliteal cysts develop from the synovial bursa located between the medial gastrocnemius and the semimembranosus, typically secondary to intra-articular pathologies causing effusion. This study aimed to describe the normal anatomy of the postero-medial capsule of the knee and its anatomical variations, particularly in the presence of popliteal cysts.

A 40-year-old female arrived with persistent posterior right knee pain, swelling in the popliteal, infrapatellar, anterior calf areas and difficulty walking due to joint stiffness. Multiple hypoechoic collections with internal echoes and debris were discovered in the anterior calf region using ultrasound imaging, which extended from a thick-walled infrapatellar hypoechoic collection with peripheral vascularity. A significant popliteal fossa cyst of comparable appearance was also observed.

Aims: We assessed diagnostic and arthroscopic surgery challenges the ruptured Baker's cysts (RBC) cases may present compared to intact Baker's cyst cases (IBC). The main question to explore was: Is RBC arthroscopic surgery more complex than IBS surgery? The null hypothesis was that RBC cases might present additional, and specific challenges for a surgeon and the arthroscopic procedure may be more complicated.
Methods: The prospective cohort study analyzed 100 operated patients (43 % female; mean age 61 ± 9.
