Chronic arthritis with persistent effusion and thickening of the capsule, whether due to infection or injury, or both, often defies the ordinary methods of treatment and proves disabling. Frequently, patients come with the story of painful swelling of the knee which has been constant for months, perhaps starting with an attack of rheumatism, a fall, or a sprain. The joint has become progressively larger, stiffer, and more disabling.
Certain of these conditions which are due to mechanical derangement of the knee cartilage, ligaments, etc., must be treated surgically for the correction of the derangement; even these cases often present a convalescence associated with chronic swelling of the joint. A small group of chronic infectious arthritis patients are benefited by synovectomy. It is difficult, however, to determine what cases are suitable for this treatment; but, if it could be accurately determined at what stage in the progress of an infectious arthritis the operation is indicated, the results would be gratifying. The operation has a definite field of usefulness, but, as Swett and others have indicated, it is not a panacea.
The results of injections have been uncertain. Occasionally there has been a decided shrinking in the size of the swelling and diminution of the secretion within the knee with relief of these symptoms, particularly when accompanied by accurate treatment of the arthritic process.
Subsequent observations seem to justify the opinion that there is a mechanical or chemical reaction caused by the pathological phenomena of increased synovial secretion that has a retarding effect on the healing process of the arthritic joint. Furthermore, if some substance could be brought in contact with the synovia that would tend to diminish its secretion and shrink the tissue substance within the joint, there would be relief of the symptoms of distention, and of the mechanical irritation of the pathological synovial formations; and, by producing a more normal joint relationship of tissues, a better opportunity would be afforded by immunization, medication, physiotherapy, etc., to render an effective result.
My attention has been directed to Pregl’s solution with which, in the clinics of Vienna, rather striking results have been obtained in the treatment of empyema, meningitis, and gonorrhoeal arthritis. This solution appeared first as a secret preparation, described by Pregl in 1919 as a non-irritating, non-staining, watery solution of free and combined iodin with certain iodides. He advocated its use in infections of all kinds, and it has been used by a large number of observers.
A résumé of the recent observations in regard to the therapeutic value of Pregl’s solution convinced me that its introduction into the joints would at least do no harm; furthermore, that the antiseptic properties and the astringent qualities exhibited by this iodin solution might prove valuable in treating chronic synovial effusions associated with chronic arthritis.
I had as a patient a doctor who, following an injury on the golf course, sustained a disabling swelling of an old arthritic knee joint. This condition had persisted for several weeks. He was willing to try anything; so with great temerity I drew out some clear, straw-colored fluid from the knee and injected five cubic centimeters of Pregl’s solution. The result was indeed commendable. Within twenty-four hours he was better and the effusion remained markedly diminished. After three injections, five to seven days apart, the effusion had entirely disappeared and he started east on a trip. To date he has had no return of his former condition.
With this initial experience, a second case was tried with an equally gratifying result. The effusion seemed to melt away; or, at least, with each injection less effusion resulted, until finally practically normal contour was established in the joint. Unfortunately, no photographs have as yet been taken of any of our patients before or after treatment. Case histories themselves must tell the story. The formula used in the method of preparation of the solution which I use is as follows:1
To a solution of crystallized sodium carbonate sixteen grams to thirty grams of water, add three grams of finely powdered iodin and allow it to stand for twenty-four hours, rotating frequently, or warm to forty degrees, centigrade, on a water bath. When all the iodin is in solution, add four grams of sodium chlorid and water to make one liter.
Bring this to .035–.04 per cent. iodin by gently warming the solution, or part of it, until twenty cubic centimeters is decolorized by .55–.65 cubic centimeters of tenth normal sodium thiosulphate; or until the tint is the same, in equal liquid depth, as that obtained by a mixture of ten drops of tenth normal iodin and fifteen cubic centimeters of water.

No reaction has been noted either of a general or local type. Sometimes a patient will complain of pain and discomfort for the first few hours; after that considerable relief is expressed uniformly. In five to seven days this procedure is repeated, and usually two to five injections are sufficient to stop the effusion and relieve the symptoms.
Thirteen cases are summarized in the table. The synovial fluid withdrawn in each instance was cultured, and no growth occurred in a single instance. The following brief survey of two cases is illustrative of the uniform results obtained in the series summarized. The first case is one in which arthritis is complicated by injury; the second is of undetermined etiology.
Case 2. Dorothy E. (City Clinic), female, aged fourteen. For six months she had had persistent swelling in both knees, the right more severe than the left. She was left with some stiffness and swelling together with pain. All tests for tuberculosis, syphilis, and gonococcus were negative. Cultures from the effusion were negative. She was under observation for three or four months. About six weeks ago twenty-four cubic centimeters of clear, straw-colored fluid were drawn from the right knee and seven cubic centimeters of Pregl’s solution were injected. After five injections the right knee had assumed nearly normal appearance and the swelling of the left knee had remained constant. Crowe’s stock vaccine was given during this period, rather empirically. Two weeks ago the left knee was aspirated and injected with Pregl’s solution, and improvement was evident at the time of the second injection. Although one of our more recent cases, she has proved most interesting in that a similar condition existed in both knees with a chronic effusion that had lasted over six months. An accurate diagnosis has not been made; but, until this treatment was instituted, the condition had become progressively worse. The right knee, which was the more severely affected, was treated for five weeks with the result that it had assumed almost normal appearance, while the left knee remained constant. Now the Pregl’s solution has been injected into the left knee, with the result that the effusion has disappeared. Both knees have assumed normal contour and appearance, and the patient now has no discomfort or disability.
Arthritis was produced by two methods, first, by introducing infection into the joint directly; second, by introduction of one-half of a cubic centimeter of one per cent. carbolic solution and one-half strength tincture of iodin. In most instances a period of two to four weeks elapsed between the operative intervention and the beginning of treatment. All operations were carried out under strictly aseptic conditions. On account of the fact that we wanted exactly similar conditions in both knee joints of the same rabbit, an exploratory arthrotomy was performed before treatment was instituted, in order to determine whether the condition of both joints was similar. Then one joint was treated with Pregl’s solution and the other allowed to heal without treatment. So far only gross specimens have been studied.
In adult rabbit No. L., streptococcus was introduced into both knee joints. Two weeks later the arthrotomy was performed and there was found a profound pannus and increase in synovia with changes about the joint surfaces of the condyles. Both knees appeared relatively the same. The rear extremities of the rabbit were numbered 21 and 29. The knee joint of No. 21 was injected with one and one-half cubic centimeters of Pregl’s solution three days following the arthrotomy. Every three or four days thereafter a similar amount of Pregl’s solution was introduced. At the end of four weeks the rabbit developed a respiratory infection and was sacrificed. There was marked synovial change and the knee joint cartilages of both looked slightly eroded. However, knee joint No. 21 (treated with Pregl’s) showed much less hypertrophy and pannus of the synovia; the joint had margins which looked almost normal, but there was some cartilage erosion of the condyles similar to No. 29.
Rabbit No. P. was a young rabbit fourteen weeks old. Both knee joints were injected with a culture of staphylococcus albus. Two weeks after injection was administered, both joints were extremely swollen and fluctuating. Effort was made to remove the effusion by needle, but the material could not be withdrawn. Exploratory arthrotomy was performed in this instance and the thick seropurulent fluid withdrawn. Knee joint of No. 42 was treated with Pregl’s solution every three to five days, while the knee joint of No. 48 was untreated. Thereafter the rabbit developed a generalized infection, and died three weeks after treatment was started. Although the cartilage of the femoral articulation of both joints was largely destroyed, there was considerable pannus thickening of the synovia about the margins of the knee joint of No. 48. The synovia of the knee joint of No. 42 was in no wise thickened, although it did give evidence of an extensive diseased process.
Rabbit No. K. had an arthrotomy of both knees with injury to the external condyle. The knees were washed with ten per cent. carbolic acid and iodin. However, the knee of extremity No. 60 was washed and filled with Pregl’s solution prior to closing the wound. No. 62 was simply closed after the carbolic and iodin had been applied in the joint. Immediate treatment was started on extremity No. 60 and was continued at intervals of from three to five days for six weeks. The result was quite striking. The knee into which the Pregl’s solution was injected after the injury and chemical trauma was practically normal, but the knee which was not treated showed extensive loss of cartilage.
Admittedly there are several sources of error in such experimental work. Microscopic sections have not been run in any of these joints. Nevertheless, there seems to be something in the use of Pregl’s solution that quite definitely affects the synovia, even in the presence of severe infection, to the extent that it apparently produces an inactivity or diminution of synovial secretion with an atrophy or shrinking of the synovia, very definitely inhibiting an infectious process and perhaps promoting cartilage regeneration. Of course this experimental data is in no wise conclusive, and the clinical material represents but a small group of cases; nevertheless, the similarity in results between the clinical cases and the experimental animals seems to warrant further investigation and a more general use of Pregl’s solution in treating chronic effusion of arthritic and traumatized joints.
