Review
Popliteal cysts presenting as thrombophlebitis are unusual diseases of the popliteal fossa and are commonly associated with rheumatoid arthritis or meniscal tears. The authors report the case of a 38-year-old man with Reiter's syndrome in which a synovial cyst of the popliteal space, mimicking symptoms suggestive of deep venous thrombosis, complicated the course of the arthritis. Clinical and diagnostic features of this rare popliteal pathology are discussed and the usefulness of noninvasive diagnostic methods for detecting this disease, in particular that of echotomography, is emphasized. The authors stress the importance of a correct diagnosis in order to avoid the risks of an erroneous anticoagulant treatment.

BACKGROUND
Popliteal (Baker's) Cysts are rare complications of knee arthroplasty. Enlargement, irritation, or rupture of the cyst can lead to significant pain, tightness, and tenderness. The literature regarding popliteal cysts occurring following knee arthroplasty is limited and does not report prevalence, natural history, and treatment of popliteal cyst in the setting of knee arthroplasty.
METHODS
Following Institutional Review Board approval, 2,025 primary total and partial knee arthroplasties by four surgeons at one institution from 2011-2016 were reviewed for occurrence of popliteal cysts. Twelve cases occurring after arthroplasty were identified, including four unicompartmental knee arthroplasties and eight total knee arthroplasties. Demographic data were evaluated and symptoms, time of onset following arthroplasty, attempted treatment strategies, and success or failure of attempted treatments or interventions were recorded.
RESULTS
The mean age of patients that presented with a popliteal cyst was 63.6 years old (range = 45 - 78 years). There were 5 males and 7 females. The mean BMI was 26.32 (range = 19.0 - 35.0). In 2,205 primary knee arthroplasties performed from 2011-2016 (including 175 partial and 1850 total), the prevalence of popliteal cysts following surgery was 0.6% (n=12). All popliteal cysts were discovered between six weeks and two years following surgery, with the majority occurring during the first year. Twenty-five percent (3/12) of patients presented with minimal symptoms. These were managed expectantly. Seventy-five percent (9/12) were symptomatic. One patient had only a diagnostic ultrasound, two patients underwent ultrasound-guided aspiration and steroid injection, three underwent simple aspiration. Two underwent surgical excision. One cyst ruptured. All cases went on to symptomatic resolution. There was no association with diabetes, smoking, or body mass index. A disproportionately high number (25% or 4/12) occurred in partial knee arthroplasty.
CONCLUSION
While popliteal cysts following primary total knee arthroplasty are rare, they can become a persistent and even disabling problem for arthroplasty patients. Given the lack of formalized recommendations in the existing literature, we propose a treatment algorithm that has been successful in our clinic, including observation initially, ultrasound-guided injection/aspiration if symptomatic, and surgical excision as a last resort.

BACKGROUND A popliteal cyst, often perceived as benign, poses potential harm and symptoms. This study focused on arthroscopic treatment through the posterior knee portal at our medical center, aiming to assess its efficacy, safety, and long-term outcomes compared to traditional methods. MATERIAL AND METHODS A retrospective analysis of 20 patients (9 males and 11 females) with symptomatic popliteal cysts (January 2020 to December 2022) undergoing arthroscopic treatment via the posterior knee portal was conducted. Data on demographics, clinical presentation, preoperative imaging, surgical techniques, intraoperative findings, and postoperative Rauschning and Lindgren scores were collected and analyzed. RESULTS With a mean follow-up of 13.6 months (range: 12 to 36 months), all patients had associated intra-articular lesions and were treated. Degenerative cartilage damage was most common (65.0% of cases). The Rauschning and Lindgren score significantly improved after surgery (P<0.05), with no recurrence evident on MRI in any patients. CONCLUSIONS Arthroscopic treatment through the posterior knee portal has good potential for popliteal cyst management. This minimally invasive approach offers benefits such as direct visualization, precise cyst excision, and concurrent treatment of intra-articular pathologies.

In regard to arthroscopic treatment of popliteal cysts, we explored the refuted pathology for popliteal cysts proposed by others. Here we introduce an arthroscopic technique using posterior portals to treat a popliteal cyst based on our observation that the opening of the cyst in the joint is a slit-like structure in the posterior wall of the capsule. By disrupting this slit-like structure with our procedure, the popliteal cyst ceased to be palpable and was no longer symptomatic. This technique also provides excellent arthroscopic visualization of the cavity of the popliteal cyst through the knee joint approach. After completion of the resection of the opening, we can easily insert an arthroscope into the cavity of the popliteal cyst from the posteromedial portal through the resected opening. Arthroscopic visualization of the cavity of the cyst showed that the inside wall of the cavity was smooth and had no synovitis. We believe that to disrupt this slit structure is the most pathologically reasonable procedure to treat popliteal cysts surgically.

OBJECTIVE
To review the results of arthroscopic treatment of popliteal cysts in our centre and analyse outcomes including complications.
DESIGN
Retrospective study.
SETTING
University teaching hospital, Hong Kong.
PATIENTS
From July 2007 to July 2009, 11 patients with symptomatic popliteal cysts were treated arthroscopically. All of them had preoperative magnetic resonance imaging to confirm the diagnosis, identify the valvular opening, and the associated intra-articular pathology. We used the Rauschning and Lindgren criteria for evaluation.
RESULTS
Intra-articular pathology like cartilage degeneration and meniscus tear were commonly associated with popliteal cysts. All patients achieved symptomatic improvement after treatment and the recurrence rate was low. No major complications were encountered. We failed to identify (and correct) any valvular opening in one patient.
CONCLUSION
From our experience, we conclude that arthroscopic treatment of popliteal cyst with correction of the valvular opening and treatment of associated intra-articular pathology is effective and safe.

A 50-year old female patient with unilateral knee pain demonstrated a recurrent ultrasound-proven popliteal cyst (Baker's cyst). Even though a proper differential diagnosis was done, the MRT of the knee showed in a secondary step a tibial fissure as the cause of the treatment-refractory knee pain and Baker's cyst. A fracture of the tibia is a rare cause for a symptomatic Baker's cysts. Mechanical, degenerative or inflamed diseases of the joint are more frequent associated with a Baker's cyst.

To reduce the damage to posteromedial knee capsule, we developed a direct extra-articular arthroscopic approach for excision of symptomatic popliteal cysts. This study aimed to demonstrate the surgical technique and present the 2-year follow-up results. Cystectomy is performed by extra-articular surgical approach through a high posteromedial portal. Twenty-one consecutive patients diagnosed of symptomatic popliteal cysts with failed initial conservative treatments were included. At a median follow-up of 29.4 months, all knees had improved clinical function assessed by Rauschning and Lindgren knee classification (p<0.001). The cysts were either disappeared (95.2%) or reduced in size (4.8%). Only one (4.8%) patient had recurrent cyst, which was solved after ultrasound-guided aspiration. This direct extra-articular arthroscopic technique could be a feasible alternative for treatment of symptomatic popliteal cysts.

Review
Fungal infections have only rarely been reported to occur in patients having undergone total knee arthroplasty. This case report documents the first known case of Aspergillus fumigatus as the offending organism. Its initial presentation as a popliteal cyst further reinforces the known association of popliteal cysts and intra-articular knee pathology.
