The stage of the gonorrhoea at which the articular affection may appear varies very much. It frequently sets in from the sixth to the sixteenth day of the discharge; it is common enough between the third and sixth or twelfth weeks, and may be delayed as late as the twelfth month. There is no constant relation between the severity of the urethral inflammation and the frequency with which, or the time at which, the articular symptoms arise; and these, once established, appear to be largely independent of the state of the urethra. On the advent of the joint affection the discharge usually continues as it was, although it often abates somewhat. Fresh attacks of gonorrhoea, even when very mild, often develop new invasions of the articular affection, as though an idiosyncrasy existed.
While the ordinary exciting causes of simple acute articular rheumatism are not necessary to the production of gonorrhoeal rheumatism, they do now and then act as adjuvants. Such are cold, fatigue, and injuries of the joints, and a severe acute arthritis is not infrequently developed during gonorrhoea under such circumstances. Other predisposing influences probably exist, the absence of which in some measure explains the infrequency of gonorrhoeal rheumatism as compared with the prevalence of gonorrhoea. Besnier holds that constitutional rheumatism, the arthritic habit, or l'héredité arthritique, is not infrequently present in the victims of gonorrhoeal rheumatism as a predisposition; Nolen269 found an inherited rheumatic predisposition in 6 out of 88 cases, and that 4 others had had rheumatism before contracting gonorrhoea; and Hutchinson maintains that it is the existence of the arthritic diathesis which enables urethral inflammation to produce gonorrhoeal rheumatism. He says: "From statistics that I have carefully collected I have no hesitation in believing that the predisposing cause of it usually is the inheritance of arthritic tendencies;" and adds, "Very often the subject of gonorrhoeal rheumatism will give a family history of gout." However, the disease often occurs in the absence of any discoverable tendency, hereditary or acquired, to simple articular rheumatism. On the other hand, persons have had one or several attacks of gonorrhoea previously that did not give rise to rheumatism. Nolen's table of 88 cases contains 12 instances of this kind. It is probable that by reducing the resisting force of the organism, scrofula, the so-called lymphatic diathesis, anæmia, and debility favor the development of the disease.

Gonorrhoeal rheumatism, like gonorrhoea, is proportionally as well as actually much more frequent in men than in women (111 men, 7 women, Nolen); and the greater proclivity of the former has been attributed to the greater delicacy, sensibility, and complexity of the structures involved in them than in women by gonorrhoea.
MORBID ANATOMY.—The lesions of gonorrhoeal rheumatism in the early stage resemble closely those of acute articular rheumatism; and it is probable, for opportunities of ascertaining by actual dissection are very rare, that the synovial membrane chiefly suffers. In more advanced stages the joints contain serous fluid in which fibrinous flakes and numerous leucocytes are found; the cartilages may be eroded and softened; and in some protracted cases even the bones may participate in the inflammation, and the changes found in polyarticular rheumatoid arthritis may be developed. Ultimately fibrous adhesions, resulting in ankylosis, may occur. Suppuration very rarely takes place, and it is probable that in such cases pyæmia is added to gonorrhoeal arthritis.
SYMPTOMS.—Gonorrhoeal rheumatism may attack any of the joints; it most commonly invades the larger at first, more especially the knee; the ankle is next in order of frequency, and then succeeds the shoulder, closely followed by the smaller joints of the hands and feet, which are very seldom affected primarily and antecedently to the larger joints. The temporo-maxillary, the sacro-iliac, the sterno-clavicular, the intervertebral, do not escape gonorrhoeal rheumatism more than they do rheumatoid or pyæmic arthritis.270 The disease most frequently invades several joints simultaneously or successively, but, soon declining in many of them, it finally becomes localized in a few or rarely in a single articulation. It is monoarticular from the first in about 20 per cent. of cases, especially in the knees.
270 Vide Fournier, Nouv. Dict. de Méd. et de Chir. Prat., t. v. p. 230: in 119 cases, knee, 83; ankle, 32; fingers and toes, 23; hip, 16; wrist, 14; shoulder, 12; elbow, 11; temp.-maxillary, 6; etc.
Gonorrhoeal rheumatism presents several clinical forms: First, Arthralgic: pains of greater or less severity, sometimes increased by movement, but unaccompanied by redness or swelling, affect one or frequently several joints; they wander from joint to joint, are liable to exacerbations, and sometimes resist treatment. This form occurs either in a chronic state in the course of an old gonorrhoea, and without other rheumatic symptoms, or as an acute affection along with other rheumatic symptoms, as in the second form. Second: Rheumatic: in this the symptoms are almost identical with those of subacute articular rheumatism or the more active forms of polyarticular rheumatoid arthritis. Several joints are usually implicated, perhaps suddenly, either quite spontaneously or after chill, exertion, or strain, or rheumatic-like pains having been felt for two or three days in the soles, ankles, or loins, the painful joints become moderately swollen, tender, and hot; pyrexia supervenes with its early chilliness, malaise, and anorexia; the temperature is not high; the profuse acid sweating and the very acid, high-colored urine of acute articular rheumatism are not observed or but transiently and to a very slight degree. In a few days the moderate febrile disturbance subsides, but the local inflammation persists, and extends to other joints, without promptly leaving those first invaded; while lingering in all it often fixes itself in one or more joints, and is apt to produce a copious and rebellious intra-articular effusion. Still, it very rarely involves as many articulations as primary acute rheumatism. The periarticular tissues usually are more involved than in subacute or even chronic primary articular rheumatism. Hence the considerable swelling from oedema on the back of the hand or foot, around the knee, behind the elbow, and the copious effusion into the adjoining bursæ and tendinous sheaths, and in the case more especially of the small joints of the fingers and toes the fusiform enlargement and deformities resulting from periostitis of the articular extremities. The pain, deformity, pseudo-ankylosis, etc. produced by these periarticular processes are very persistent and rebellious, and, although they do usually disappear at last, occasionally the inflammatory irritation extends to the cartilaginous and osseous structures, and rheumatoid arthritis with its permanent deformities results. It is perhaps chiefly in this polyarticular form of gonorrhoeal rheumatism that cerebral, spinal, cardiac, pleural, and ocular complications most frequently occur. In the Third form, or Acute Gonorrhoeal Arthritis, after two or three days of pain wandering from joint to joint, a single articulation suddenly, and frequently about the middle of the night, becomes the seat of atrocious and abiding pain, followed in a few hours by very considerable swelling of the articulation, not due chiefly to articular effusion, but to periarticular oedema and enlargement of the bones. The pain and tenderness are most severe at the line of junction of the articular surface; the swelling begins at that point, and extends widely, especially over the dorsal aspects of the wrists and elbows, the joints most liable to this form, although any articulation may suffer. The joint is also hot, it may be pale, but is usually more or less red, and occasionally presents the appearances of severe phlegmonous inflammation, and excites a sensation of pseudo-fluctuation.271 The affection may resolve, or fibrous ankylosis may ensue, or very rarely suppurative destruction of the articulation may occur, although such issue has been denied (by Fournier, Rollet, Voelker). It is remarkable that, like the other forms of gonorrhoeal rheumatism, the acute inflammatory form is not accompanied by a general febrile disturbance at all proportionate to the severity of the local disease. A Fourth form occurs as a Chronic Hydrarthrosis. Although occasionally accompanying the polyarticular variety, it is frequently observed independently, and is then often monoarticular, and affects especially the knee; however, both knees sometimes are involved. The ankle- and elbow-joints suffer much less commonly than the knee. The effusion into the articulation takes place insidiously, although rapidly producing considerable enlargement of and fluctuation in the joint, without local heat, redness, or tenderness, and often with but little or no pain or pyrexia. It is not as often associated with inflammation of the tendinous sheaths and bursæ or of the eye as the polyarticular form, but it is apt to be very slow in resolving, and may last for two or three months, a year, or several years, and in scrofulous patients may degenerate into white swelling. The formation of pus in the joint is very rare. It occurred twice in 96 cases tabulated by Nolen; hydrarthrosis obtained 12 times; and serous synovitis 64 times; chronic rheumatism or arthritis deformans 5 times; tumor albus once.272 A Fifth form of gonorrhoeal rheumatism, like other varieties of so-called secondary rheumatism, involves predominantly the tendons and tendinous sheaths, the bursæ and periosteum, sometimes without, but far more frequently in association with, affection of the joints. Pain, sometimes severe and increased by movement and pressure and aggravated at night, with local swelling and tenderness, are the symptoms. In their fixity and persistence, their tendency to relapse, and their chronic course these periarticular affections resemble gonorrhoeal inflammation of the joints. Gonorrhoeal bursitis is often severe enough to resemble phlegmon, but it does not end in suppuration; it is most common in the bursæ covering the patella, the olecranon, and especially in that under the tendo Achillis and the deep one covering the inferior tuberosity of the os calcis; but any of the bursæ may suffer from gonorrhoeal rheumatism. The periosteum in the vicinity of the affected articulation and over the most prominent parts of the bones is sometimes the seat of small circumscribed firm nodes which are painful and tender, and may either resolve rapidly or very slowly (Fournier).
