This study was conducted to assess ultrasound (US) and clinical changes of Baker's cyst (BC) of patients with knee osteoarthritis (OA) after steroid injection. Patients with knee OA complicated with symptomatic BC (40) were treated with US-guided direct (posterior) aspiration. The injection of 40 mg triamcynolone acetonide was in 20 patients direct into the BC and in other 20 subjects intra-articular (anterior). BC diameters (longitudinal, transverse, and thickness) were measured and followed up with US at baseline, 2, 4, and 8 weeks after injection. Swelling, pain, and range motion were scored at clinical examination with Rauschning and Lindgren classification (RLC, since 0 normal to 3 maximal signs). All US measures of BC and RLC significantly decreased after treatment, in comparison to baseline (p < 0.001) and during the follow-up, did not change through the time (no significant difference between 2, 4, and 8 weeks). At 4 and 8 weeks, diameters measured at US are lower when BC is directly infiltrated in comparison to intra-articular injection (p < 0.01). US steroid direct injection reduces US measures and clinics of BC in knee OA, in particular, when steroid is directly infiltrated into BC.

PurposeTo evaluate the efficacy of the direct arthroscopic excision of a popliteal cyst without additional skin incision using a posteromedial portal based on minimum 2 year follow-up clinical results.Materials and MethodsFrom January 2003 to January 2010, 105 patients (111 cases) with popliteal cyst have been treated by a direct arthroscopic excision. Direct arthroscopic excision using a 70 degree arthroscopy and posteromedial portal can correct the valvular mechanism of capsular fold and reduce the complications with no additional skin incision at the popliteal area. In all cases, preoperative magnetic resonance imaging (MRI) was performed to detect combined intraarticular pathology. At 2 years postoperatively, a follow-up ultrasonography or MRI was performed to detect the recurrence of cysts. We used Rauschning and Lindgren criteria for clinical evaluation.ResultsAll cases had neither recurrence nor complaints of pain, swelling, or functional impairment more than 2 years after the surgery. At ultrasonography or MRI, no recurrence was found, and 5 complications were 1 skin lesion and 4 hematoma. Postoperatively, Rauschning and Lindgren criteria were more than grade 1.ConclusionsDirect arthroscopic excision using 70 degree arthroscope and posteromedial portal is an effective method for the treatment of popliteal cyst.

“…T he prevalence of popliteal cysts in the general population is unknown; however, the incidence of popliteal cysts in patients seeking treatment for knee pain has been reported to be 5%-58% (Moore, Sarti, & Louie, 1975;Sansone, DePonti, Paluello, & Del Maschio, 1995). The popliteal cyst, also known as a Baker's cyst, is caused by distention of one of the bursae in or around the popliteal fossa.…”

Recurrent Popliteal Cyst in an Adult

Popliteal cysts are typically secondary to an intra-articular pathology in adults but may occur as primary lesions unrelated to knee injury. Careful examination of any mass forming on the posterior aspect of the knee is needed to differentiate benign from malignant conditions. Asymptomatic cysts are often treated conservatively, whereas surgical intervention is recommended for troublesome cysts and for those related to intra-articular derangements. Surgical intervention focused on amelioration of intra-articular derangements and the communication between the knee and the popliteal cyst results in cyst recurrence of less than 5%. A report of a recurrent popliteal cyst, in spite of aggressive surgical intervention, is presented.
