The clinical diagnosis and results of conservative treatment of knee distortion injury.

Distortion of the knee joint is a considerable trauma even when the knee is primarily stable. Of 50 patients, 30% displayed symptoms or signs 2 months after the injury and 36% on subsequent examination an average of 5.6 years later. In a repeat clinical examination one anterior cruciate ligament rupture was not confirmed at the primary stage (2%). For assessment of stability and extent of injury, the repeat clinical examination proved reliable. Ruptures of the meniscus were noted in 18% of the patients in connection with the primary injury. Of those who underwent a meniscus operation, 27% had further operations and, four patients of 50 had another operation as a result of a new trauma. Thus, a total of 25% of the patients required surgery. The material is biased as I sought to exclude ligament ruptures in the first instance. No patient was permanently incapacitated from work. A large portion of the later symptoms were connected with the patellofemoral joint or with the postoperative condition. Bandaging did not affect the resulting recovery rate. Regular exercise of the thigh muscles prevented the onset of quadriceps atrophy, but there was a clear deterioration in the condition of the muscles in the early stages.

Silicone implant arthroplasty in Kienböck's disease.

Fifty-five patients with malacia of the carpal lunate treated by Swanson's silicone implant arthroplasty were reexamined. The follow-up period averaged 3 years. The operation had a favorable effect on pain, but the range of motion and the grip strength remained impaired. Arthrosis progressed in half the cases, and there were five dislocations of the implant and 11 cases of cystic changes of carpal bone.

Development of heterotopic ossification around the hip. A long-term follow-up of patients who underwent surgery with two different types of endoprostheses.

Heterotopic ossification has been reported in many pathological situations, most important clinically as a sequel to hip arthroplasty and spinal trauma. The etiology of heterotopic ossification is yet not clear, but the disease is supposed to be connected with trauma. Heterotopic bone was found in 53% (1.2% with the severe form) of 623 patients operated on at the Orthopaedic Hospital of the Invalid Foundation, Helsinki, Finland; the operations included 849 arthroplasties. The rate of heterotopic ossification was higher after revision arthroplasty, following operation of the contralateral side, in men, and in primary coxarthrosis, and the incidence was higher with the Brunswik (metal-on-plastic) endoprosthesis than in the McKee-Farrar type (metal-on-metal). Heterotopic bone formation generally seemed to increase and to be more manifest during long-term observation.

Silicone rubber implant arthroplasty of the metacarpophalangeal joint in rheumatoid arthritis: a follow-up study of 32 patients.

A retrospective analysis of silicone rubber implant arthroplasty of the metacarpophalangeal joint in 32 patients with rheumatoid arthritis is reported. One hundred seven implants were followed in 37 hands for an average of 44 1/2 (12 to 120) months. Active motion of the metacarpophalangeal joint averaged 34 degrees, with a mean extension deficit of 7 degrees and a mean flexion 41 degrees. Ulnar deviation recurred to more than 10 degrees in 33 of 107 fingers (31%). Fracture of the spacer was confirmed in four joints (4%). One fracture of the proximal phalanx and one of the metacarpal head had occurred. Bone resorption around the stem or a hinge and migration of the implant were found in 26 (24%) fingers. Patient satisfaction was high; 27 patients experienced significant pain relief, the functioning of 31 hands (84%) was improved, and 28 patients (32 hands) thought that the cosmetic appearance of the hand was improved.

Mechanics of knee and ankle bandages.

Different types of bandages were tested mechanically and clinically. Four elastic and three elastic adhesive bandages were mechanically tested. The former proved better. Seven different ankle bandages and three knee bandages were tested in a simulated clinical situation, measuring the pressure which developed while walking for 15, 50 and 100 min, and immediately after application of the bandage. The bandages slackened most markedly during the first period of walking. The compression pressure of the padded adhesive ankle bandage was lower than that produced by most other bandages. The padded adhesive and elastic bandages proved to be most suitable for clinical use. The padded knee bandage produced a lower compression load than the elastic bandage tested. On the basis of this trial we recommend the use of a padded knee bandage.

Value of bandaging after excision of a meniscus of the knee joint.

Thirty patients with meniscus tears, not complicated by any other disease of the knee joint, were divided into two groups, the purpose being to find out whether postoperative bandaging had any effect on postoperative recovery. One group was not bandaged, while in the other group a padded layer bandage was applied. This was removed one day after the operation. The operative technique and the postoperative treatment were the same in both groups. The clinical state was assessed preoperatively, three days, seven days and five weeks postoperatively. There were no significant differences between the groups in the range of knee movements, ability to elevate the straight leg, circumference of the knee, the thigh or the ankle, or in the duration of sick-leaves. Bandaging did not promote recovery after excision of a meniscus of the knee in this regime of treatment.

The treatment of ankle sprain by bandaging and antiphlogistic drugs.

A prospective randomized investigation comprised 119 patients with ankle sprains, treated by the application of a layer bandage or elastic adhesive tape bandage. In addition, the patients received drug treatment as a double blind test: placebo, or oxyphenbutazone 100 mg or clonixin 300 mg three times daily. The drug study comprised 106 patients. Clinical examination and measurements of foot volume were carried out initially and 5-7 days after injury. The patients were asked to complete a follow-up questionnaire describing their symptoms and walking ability. No statistically significant difference was observed between the differently bandaged groups with regard to clinical findings and foot volume. Elastic adhesive tape bandage caused more complications, mainly compression, irritation of the skin or rash, compared with the layer bandage (p less than 0.05). Clonixin proved useful in controlling swelling and in the authors opinion gave the best clinical result. The bandages used in the study were tested in 20 patients by mechanically rotating the bandaged ankle under general or spinal anaesthesia. The layer bandage proved more stable in the lateral direction than the elastic adhesive tape bandage (p less than 0.001).
