Effect of Hirudotherapy in Bakers Cyst
Bakers cyst is also known as popliteal cyst. There is collection of fluid behind the knee joint & is due to swelling of popliteal bursa. This type of the abnormality usually does not show any symptoms. However in chronic cases with secondary trauma or wear & tear, there may be swelling, pain, tenderness & the affected knee may get stiff. In allopathic medicine the treatment given is purely supportive care and if it does not suffice then aspiration is done. In some cases steroid injection or sclerotherapy is given & if it fails or show recurrence, then surgical removal is the treatment of choice. Keeping the side effects, short falls, recurrence & cost effect in view Hirudotherapy has been used for the treatment of bakers cyst. Here 5 leeches were applied locally at the popliteal fossa preferably on the swelling. The procedure was done every after 10 days & total number of therapies given were five. It was observed that the cysts was completely resolved in all of the patients and did not show any recurrence even after follow up for 2 year.
Introduction
Baker’s cyst was first described by William Morrant Baker [1] & was first described in 1840 by Adams as popliteal cyst [2]. It represents fluid collection & destruction of the gastroenemius-semimembranous bursa which usually communicates with the knee joints in adults and the cyst most often contains upto 40ml of fluid [3].This cyst is clinical found in the chronic osteoarthritis patients and in patients with degenerative joint diseases. The risk factor can be osteoarthritis, meniscal tear; Rhematoid artheritis [4, 5, 6]. The Baker’s cyst is diagnosed clinically & can be confirmed radiologically by ultrasound or MRI (Magnetic resonance imaging). The differential diagnoses of acute calf pain include DVT, Baker’s cyst, muscular injury, tumour, infection, arterial aneurysm, and Achilles tendon pathology [7]. Emphasis is often placed on DVT owing to the risk of pulmonary embolism. Ultrasonography has largely replaced arthrography for the initial assessment of Baker’s cyst [8]. In ultrasonography, Baker’s cysts are demonstrated as consisting of three parts: the base, the superficial part, and the neck in between. The neck lies between the medial head of gastrocnemius and the semimembranosus tendon. Baker’s cysts can be complicated by dissection, which usually occurs in a distal direction [9]. Cysts can rupture and their fluid content can track into the fascial planes between the soleus and gastrocnemius muscles.
This can cause inflammatory changes within the subcutaneous fat and muscles. The clinical appearance of the leg can be very similar to those with acute thrombophlebitis. Therefore, ruptured Baker’s cyst is also referred to as 'pseudo thrombophlebitis'.
Materials and Methods
Around 20% of people have Baker’s cyst [5, 10]. Baker’s cyst occurs most commonly between 35 to 70 year of age [6]. 4.5%Incidence is found in patients undergoing radiological investigation like MRI for some other problem [11].It has been reported that in 94% of patients baker’s cyst has been associated with one or more disorders related to knee joint and the local compression of sciatic nerve due to proximal dissection of cyst [12, 13]. A study reveals that 40% of patients with osteoarthritis had baker’s cyst detected by ultrasonography. In rheumatoid arthritis, up to 48% of patents have been shown to have baker’s cyst [14]. Bilateral cyst where seen in 16% of the patients. Distribution of Patients According To Mizaj (Temperament) The present study is single group open clinical study. Seven patients were selected from general OPD of Regional Research Institute of Unani Medicine, University of Kashmir, Srinagar & screened before undergoing the scientific study. The local part (Popliteal fossa) was prepared by initially washing with plain water & then full antiseptic measures were taken to avoid any sort of infection. The patients were given Hirudotherapy every after ten days for a period of fifty days. The leeches were put locally on the swelling (Baker’s Cyst) & allowed to suck till they fill up their belly & fall down of their own.
Five leech were applied on day one & at every follow up. The part were allowed to bleed for about 1 to 2 hours & then antiseptic bandaging were done.

Discussion
Baker’s cyst usually arise due to chronic osteoarthritis, Rheumatoid atheritis or due to menescial taer. Baker’s cyst is now a days the commonest menifertation and mostly become symptomatic when associated with some associated ailments like deep venous thrombosis, chronic OA with osteophyte formation, thrombophlebitis, local trauma. In case there is increased accumulation of fluid in the cyst, there may be local pain with swelling and if the cyst ruptures it causes bruising below the Medial malleolus of the ankle known as crescent sign.
In children the Baker’s cyst may not be due to any underlying joint disease. The baker’s cyst arise between the medial head of the gastrocnemius and the semimembranosus muscles. They are posterior to the

Conclusion
Baker’s cyst is common clinical entity which is easily diagnosed clinically and can be well confirmed radiologically by ultrasonography and MRI. The cystic leasion exteds between the tendons of semimembranosus and the medical head of gastrocnemius remain the key to the diagnosis. From this entirely new study it has been observed that Hirudotherapy played and significant role in the treatment of baker’s cyst by way of draining the local joint inflammation due to natural anti-inflammatory and natural steroids present in the leech saliva. It is also presumed that the bioactive substances present in the leech saliva regulate the vascular blood flow smoothly without any occlusion due to Hirudin, Calin, Hirustasin, & Bdellins like substances present in leech saliva. The bioactive substances like Hyaluronidas in presumed to be responsible for resolution of the morbid material (Galeez Aklat) at the joint space and hereby Hirudotherapy plays a paramount role in the treatment of baker’s cyst.
