The morbidity associated with lost or irretrievable resected meniscal fragments.

Between January 1984 and April 1989 pieces of already-separated meniscus were lost in the knees of 23 patients as a complication of knee arthroscopy. These patients were asked to complete a questionnaire with regard to their postoperative problems. Despite the fact that some of these pieces were up to 4 cm in length, only 3 patients were dissatisfied with the results and had to undergo arthroscopy once again. When compared with the total number of arthroscopies (2,927) performed in the same period, we found no significant differences in patient ages, accompanying injury patterns, nor the time they were unable to work. These surprisingly excellent results demonstrate that a lost piece of meniscus in the knee space does not always indicate immediate repeat arthroscopy. In most cases, this loose piece probably will adhere to a place inside the knee where it will no longer be a mechanical hindrance.

[Arthroscopic meniscus resection].

The problem in surgery of the meniscus has been the inability of the surgeon to assess the situation regarding the rest of the meniscus. Because arthroscopy permits a good view of all parts of the meniscus, we can make a decision about the extent of the damage. The results of partial resection are better, and total meniscectomy is now the exception. The damage starts in the middle of the meniscus body. The meniscus tears if there is central damage on the outside (ganglion) or inside (meniscus tear). The well known operative techniques are described briefly and our own results after arthroscopic surgery an presented. Arthroscopic partial meniscectomy represents great progress compared to the conventional operation. The operation not only shows better results, but also fewer complications and reduces the time when patients are unable to work.

The areas of contact pressure in the patello-femoral joint.

The development of damage to the articular cartilage of the patello-femoral joint depends on many factors. Pathological distribution of pressure in the joint may be one such cause. Direct measurement is required to clarify the question of low and high pressure in this joint. A pressure measuring plate has been made in the form of an air cushion which enables the measurement both of pressure and contact area in the knee joint. Tests using three cadaver knee joints and the results are described.

[Arthroscopic evaluation of cartilage lesions in the knee joint].

Arthroscopy constitutes an important supplementary method for investigating and diagnosing affections of the knee joint. Despite the low risk and little trouble it causes to the patient it should only be used if radiological and repeated clinical examinations do not permit any evaluation of the disease. Arthroscopy is the method of choice in case of cartilage damage because from the appearance of the altered cartilage conclusions may be drawn about the occurrence and kind of the trauma. This examination method is valuable not only in diagnosis, it is also used to follow up the result of surgical interventions. Small pieces of cartilage that cannot be fixed may be removed by means of the arthroscope, so that examination and therapy can be done in one single operation. In most cases, cartilage damage is caused by laxity of ligaments.

[Complications of arthroscopy. A review of 3714 cases (author's transl)].

This review is drawn from a total of 3,714 knee arthroscopies carried out on patients from six clinics. The diagnostic value of arthroscopy at this site is established for it can improve prognostication, prevention and treatment of derangements of the knee. The complications of the procedure, both theoretical and in practice, have been considered by subdividing them into four groups. Firstly, the infection rate following arthroscopy alone was nil. Secondly, minor articular cartilage damage attributable to the instrument occurred in just over 2% of cases. This complication is more common when the technique is first being learned and is usually avoidable when experience has been gained. Thirdly, complications of a general nature included four cases of subcutaneous emphysema produced by the insufflation of gas, and 22 instances of an allergic skin reaction to the disinfectant preparation. Finally, failures in the technique itself resulted from the instrument bending or breaking when negotiating the condyles. This occurred on 26 occasions. In a further seven instances the fat pad was entered and distended in error, thus preventing examination of the joint. Overall, the complication rate was acceptable low and confirmed that arthroscopy can be safely applied clinically.

[The improvement of pulmonary function after scoliosis treatment via Harrington's method (author's transl)].

53 spine fusions using Harrington's method were performed in adolescents (average age 14 years) between 1966 and 1972. Follow-up examination at early intervals showed that the values for pulmonary function, particularly the vital capacity, are lower one year after operation but then definitely increase in the following years. The percentual increase is not statistically significant. The evaluation must take into account, however, that the normal values for pulmonary function in these patients increase markedly because they become 4--5 cm taller on operation. Spine fusions using Harrington's method not only prevent deterioration of pulmonary function but also lead to its improvement. Further evaluations should be carried out to discover to what degree scoliotic patients are trainable without increasing the danger of pulmonary vascular obstruction.

[The McBride operation of hallux valgus in adolescents (author's transl)].

Severe Hallux valgus deformity in adolescents and young adults has been treated by the McBride operation in 53 cases during the period from 1965 to 1974. With 85% good results in our material this type of operation is very satisfactory. Other authors have made the same experience. The principles and technique of this soft tissue correction are described and the results of reexamination presented.

[Treatment of pathologic fractures].

Eight pathologic fractures of benign and 52 of malignant origin are reported. Open reduction and rigid internal fixation should be performed to give the patient the use of his affected limb as soon as this can be accomplished. Treatment consists of internal fixation in lesions of the shaft and prosthetic replacement in the case of lesions near joints. Only very rarely a primary amputation must be performed. Malignant fractures are most frequently caused by metastases from breast cancers. The treatment will at least make nursing easier, and three-quarters of these patients can be mobilized. The combination of surgical treatment and radiotherapy is discussed. In spite of this approach the average time of survival of 14 months is short because a pathological fracture due to a malignant tumor is a late symptom of the disease.

[The cartilage-damage after fracture of the patella].

At least 16 cases of posttraumatic chondromalacia of the patella out of a total of 79 patients operated between 1968 and 1971 were diagnosed on the basis of a questionnaire and follow-up examination. The clinical findings and delineation of this complaint from femoro-patellar osteoarthritis are discussed. The diagnosis was confirmed by arthroscopy in 2 patients. The significance of cartilagenous damage due to direct contusion is pointed out. The mechanisms which result in a degradation of the cartilagenous layer in the weeks following the accident are mentioned. The therapeutic consequences for the treatment of fractures of the patella are as follows: One must aim at exact bony reduction. Macroscopically damaged parts of the cartilage should be removed. Indication to partial patellectomy should be on a broad basis. A long term treatment with salicylic acid or Chloroquin-both of which are said to prevent enzymatic degradation of cartilage-should be considered.
