Some aspects of “Baker’s Cyst” with homoepathic mode of treatment

Also known as a ‘Popliteal Cyst’, Baker cyst is a distended bursa caused by knee joint fluid protruding to the back of the knee. It is thus a benign swelling & is named after Dr William Morrant Baker who first described this health condition. The term is a misnomer as it is not a true cyst but is due to synovial fluid distending the bursa.
Aetiology-
(1) Idiopathic- Baker cysts may sometimes develop without any apparent cause particularly in children.
(2) Infection- Local infection may cause a retention of fluid with the subsequent formation of a Baker cyst.
(3) Trauma or injury to the knee- It may cause an effusion, thus triggering the formation of a Baker cyst.
(4) Arthritis-Arthritis is the most common & osteoarthritis probably the most frequent among arthritides.
(5) Internal derangement of knee- Internal derangement of knee like meniscal tears etc. may cause an effusion resulting in the formation of a Baker cyst.

Location- It is located posterior to the medial femoral condyle, between the tendons of the medial head of the gastrocnemius & the semimembranosus muscles.

Age- Baker cysts appear much less frequently in children than in adults.

Pathology- Being an extension of the knee joint, a Baker cyst is a synovial cyst lined with a true synovium. In most cases herniation of synovial membrane through posterior part of capsule takes place. . Escape of fluid through the normal communication of bursa with knee is the other mode. The knee joint effusion caused by intrinsic intra-articular disorders or any other cause is displaced into the popliteal bursa, thus reducing potentially destructive pressure in the joint space. So a Baker cyst may have a protective role to play for the knee. In such cases, the popliteal bursa becomes filled up with fluid & consequently expands resulting in the formation of a swelling. The cyst usually communicates with the joint by way of a slit-like opening or may pinch off.

Associated health conditions-Medical conditions associated with Baker cysts are as follows-
(1) Arthritis is the most common among which osteoarthritis is the most important. Rheumatoid arthritis, Juvenile rheumatoid arthritis etc are also common.
(2) Internal derangement of knee like meniscal tears etc.
(3) Infection like septic arthritis.
(4) Miscellaneous- Hypothyroidism, Gout, Psoriasis, Systemic lupus erythematosus, Sarcoidosis, Haemophilia, etc.

Clinical features- May be asymptomatic or may have the following features in addition to the features of the underlying primary cause-
(1) A slight swelling behind the knee which is particularly noticeable on standing & when compared to the opposite uninvolved knee.
(2) The swelling is usually soft & fluctuant & is with or without pain. Typically these cysts are not painful unless swelling is extensive.
(3) A sensation of tightness behind the knee, especially when the knee is extended or fully flexed.
(4) Restricted mobility of the knee joint.
(5) Transillumination- Transillumination by a shining light through the cyst may show a mass filled with fluid.
(6) In case there is rupture of the cyst, calf tenderness & bruising at the ankle may be present.

Investigations-
(1) X-ray- An X-ray of the knee joint will not show any cyst, but it may show the presence of other abnormalities which may cause development of a Baker cyst.
(2) MRI- An MRI helps to show a cyst with its size & location.
(3) Ultrasound- An ultrasound can also determine the location & contents of a cyst.
(4) Arthrogram- Arthrograpgy may also be utilized for its detection & it is more sensitive than ultrasonography in its detection.

Complications- A Baker cyst may sometimes compress vascular structures & may cause a deep vein thrombosis. It may also rupture & cause extravasation of fluid in the calf. There may also be haemorrhage into the cyst in some cases, particularly if there is any associated bleeding disorder. Infection in case of a Baker cyst is very rare.

Differential Diagnosis- A Baker cyst may sometimes be confused with thrombophlebitis or deep vein thrombosis from which it is to be differentiated by urgent blood tests & other investigations. It may also sometimes be confused with septic arthritis or a ganglion cyst.

Treatment-
[A] General measures to be taken are-
(1) Treatment of underlying cause like arthritis or torn knee cartilage.
(2) Temporarily avoiding activities that may increase the load on the knee joint. (3) Physiotherapy.
(4) Exercises to maintain mobility & strength of the knee joint.
[B] Homeopathic medicines to be used – Homeopathy can be very effective if properly used. Homeopathic medicines to be used depend on the size of the cyst along with its cause & the symptoms produced. Ruta Graveolens (Ruta), Rhus toxicodendron (Rhus tox), Bryonia etc. may be used. The potency & frequency of dosage as well as duration of treatment varies with the severity of the condition & the individual

Prevention- Prevention of knee injury is essential for reducing the risk of development of a Baker cyst for the first time or its recurrence after treatment. Hence supportive footwear appropriate to the activity of an individual is to be worn as well as stoppage of the activity & seeking of medical advice after an injury is needed.
Prognosis- Prognosis of Baker cysts depends on the presence of any underlying knee pathology & the degree of its response to treatment। Most Baker cysts without any underlying knee pathology disappear spontaneously after several years, particularly in children & young adults in whom usually there is no underlying knee pathology। But in some cases a Baker cyst continues to grow with worsening of the symptom & ultimately may rupture & produce acute pain behind the knee & in the calf & swelling of the calf muscles।

In short, a Baker cyst manifests itself as a soft swelling behind the knee with or without pain & can be treated by Ruta, Rhus tox or Bryonia.

But in every case, a doctor should be consulted.

Some aspects of “Bursitis” with homoepathic mode of treatment

Bursitis is inflammation of a bursa. A bursae is a cushion like sac lined with membrane similar to synovium which is located between a tendon & a bone thus reducing friction between them & allowing the tendon to glide easily over the bone. When subjected to repeated pressure due to over & abnormal use it gives rise to bursitis.

Site of lesion-
Bursitis most often occurs in –
(1) Shoulder .
(2) Elbow.
(3) Knee.
(4) Hip.

Causative factors-
(1) Overexertion of a joint. The repeated motion of a joint causes friction in the bursa. Subsequently, with continuation of activity, the bursa becomes inflammed & filled with fluid. The bursa thickens & does not function well. Both the bursa & the tendon become irritated.
(2) Occasionally a bursa will become infected by haematogenous spread or due to open trauma to the overlying skin or blow to an area containing a bursa.

Clinical features-
Presentation -The patient presents with complain of pain, stiffness of a joint along with malaise & possibly fever.
Signs-
(1)Pain, tenderness & redness of the area of the affected bursa .
(2) Swelling & warmth around the area of the bursa.
(3)Restricted movement of the nearby joint with the subsequent result of restricted function of the affected limb.

Differential Diagnosis- Bursitis has to be differentiated from acute exacerbations of rheumatism & flare-ups of gout both of which clinically manifest with significant erythema & swelling.

Treatment-
[A] General measures to be taken are-
(1)Rest to the affected area & protecting the area from any kind of trauma.
(2)Exercise & application of heat.
(3) Stopping of the activity causing pain if the bursitis is a chronic one.
[B] Homeopathic medicines to be used are-
Benzoicum acidum (Benz.ac)- It acts well when the pain is tearing with stitches & the adjacent joint cracks on movement.
Bryonia- It may be used when the adjacent joint is stiff & painful & the pain is of stitching or tearing type & becomes worse from even the slightest motion.
Belladonna (Bell)-It acts well when there is shooting pain along limbs.
Rhus tox -This remedy is particularly helpful where there is pain on initial movement which gradually improves with movement. The pain may also be worse during sleep & in the morning on waking.
Silicea (Sil)- It acts well when the pain seems to be tightly bound & the sensation seems to be suppurating. Ruta graveolens(Ruta) – This remedy is particularly useful for bursitis after any injury. It is also helpful in acute bursitis with great stiffness & aching pain.

Some points to be kept in mind-
(1) The potency & frequency of dosage varies with the severity of the condition & the individual. Usually a lower potency like 30C is to be used first for thrice daily & to be continued till the persistence of the symptoms. If improvement is seen, the same medicine is to be continued. But if there is no significant improvement or improvement has come to a standstill, the frequency of dosage should be increased. And in cases where there is no response within a reasonable amount of time, the medicine should be stopped & a different medicine is to be started.
(2) If bursitis is caused by an infection, the infection should be combated first in addition to treatment of bursitis.
(3) If bursitis is related to any inflammatory condition such as arthritis, or gout, the disease is to be treated also for control bursitis.

Prevention-
(1)Wearing of protective pads if participating in contact sports.
(2)No overdoing of any kind of sports & activities & that too to be done correctly.

Prognosis- In general, bursitis has a favourable result if treated early but if the underlying cause is not removed properly it may develop into a chronic condition.

In short, bursitis manifests itself as a tender, warm, swelling adjacent to a joint & can be treated by Benz।ac, Bryonia, Rhus tox, Ruta or Silicea.

But in every case, a doctor should be consulted.
