Results of arthroscopic treatment of degenerative meniscal tears (meniscosis).

The aim of this paper is to propose a new classification of degenerative meniscal tears and assess the validity of arthroscopic treatment. The study is based on 37 of the 47 patients treated, and the average follow-up was 2 years and 2 months. The cases were evaluated using previously adopted systems (HSS, Tapper and Hoover) as well as a new method proposed by the authors. The results were satisfactory (excellent and good) in 68% of the patients who did not have moderate to severe osteoarthritic changes, while patients with these changes had a 66% rate of unsatisfactory (fair or poor) results.

[Changes in plasma myoglobin levels in ischemic heart disease].

The aim of the present study is to evaluate the real need and the sensitivity of serum myoglobin levels as an early index for the diagnosis of acute myocardial infarction. A total of 62 patients (38 suffering from acute myocardial infarction, 16 from "angina pectoris", 8 from heart failure) and 20 healthy volunteers were included in the study. The patients with acute myocardial infarction were divided in 3 subgroups according to the time passed between the beginning of the pain and their admittance to our Department (Coronary Care Unit), that was, less than 6 hours, between 6 and 12 hours, between 12 and 24 hours. Among the patients with "angina", 8 presented spontaneous crisis whereas 4 had crisis only during treadmill test. 8 of the healthy volunteers received intramuscular injections of physiological solution every 12 hours during the 3 days preceding the study. In all subjects serum myoglobin level were measured by radioimmunoassay; in patients with acute myocardial infarction serum CK and MBCK levels with enzymatic method were measured too. No variation of plasma myoglobin levels was seen in patients with angina, neither in healthy volunteers had they received or not intramuscular injections. The low increase in plasma myoglobin levels observed in patients with heart failure might be due to a deficit of renal function. Serum myoglobin levels were significantly elevated in all the patients with acute myocardial infarction, whereas plasma CK and MBCK levels were significantly high only 6 hours after the necrosis. In myocardial infarction the levels of myoglobin rise during the first hours, peak at 10 hours and return to normal in 20 hours.(ABSTRACT TRUNCATED AT 250 WORDS)

Reconstruction of the anterior cruciate ligament by semitendinosus transfer in chronic anterior instability of the knee.

Between 1979 and 1983, 127 chronic anteromedial or anterolateral instabilities of the knee were submitted to surgical treatment (Hughston et al., 1976; Imbert, 1984). The central pivot was reconstructed by the semitendinosus tendon, using our own modification of the original Hughston technique (Puddu et al., 1986). On the medial side we advanced the posterior oblique ligament and reflex tendon of semimembranosus in cases submitted to medial meniscectomy at the same time. Laterally, we always advanced the biceps. As this method produced excellent results very quickly, it was later improved by associating the gracilis tendon with the semitendinosus. Assessment of the results was based on an average follow-up of 5 years (minimum 4, maximum 7). Of the 127 patients we personally interviewed 108 and clinically evaluated 88 professional sportsmen. The results in the latter group were excellent or good in 76.

Long-term assessment of negative arthroscopies.

A study of 75 patients was performed to assess the accuracy of arthroscopy carried out for clinical diagnosis of meniscal tear. In these patients, arthroscopy did not detect any intraarticular pathology that could explain the preoperative symptoms. Of the 75 patients, seven were subsequently reoperated on, but in 68 the typical symptoms of meniscal tear improved after the diagnostic arthroscopy.

Isokinetic evaluation of the knee after arthroscopic meniscectomy: comparison between anterolateral and central approaches.

Twenty patients had undergone arthroscopic meniscectomy for medial bucket-handle meniscal tears. Half had undergone meniscectomy with central approach, and half had been treated by anterolateral technique. Isokinetic evaluation, with a Cybex II isokinetic dynamometer, was done preoperatively and at 14 and 28 days postoperatively. Two weeks after operation, there was only a slight and insignificant decrease of quadriceps function with the central approach as compared with the anterolateral. However, at 4 weeks, no differences were shown between the two portals. The flexor muscles generally recovered more rapidly with the central technique.

Chronic anterior laxity of the knee: classification and coding of the results of surgical treatment.

Between April 1976 and December 1983 we treated 578 cases of anterior capsuloligamentous laxity of the knee surgically (148 acute and 430 chronic). The chronic cases were treated by a variety of techniques; peripheral plastic repair (191 cases), reconstruction of the anterior cruciate ligament with semitendinosus (127 cases), and with semintendinosus and gracilis (112 cases). To achieve uniformity of classification in such a large number of cases it was necessary to simplify and consolidate the data relative to history, objective examination, operative findings and criteria of evaluation of the results. A personal computer was used to provide rapid processing.

The natural history of jumper's knee. Patellar or quadriceps tendonitis.

We have reviewed the clinical records and the results of conservative and surgical treatment of 125 out of 172 cases of Jumper's Knee followed for at least 2 years since the onset of symptoms. All were athletes involved in various sporting activities. At follow up 15 patients had given up sport and the lesion had healed spontaneously. We used the classification of Blazina et al as modified by Roels et al. Twenty-four patients were in stage 1, 42 in stage 2, 43 in stage 3 and one in stage 4. Conservative treatment was used primarily on all patients with one exception where the tendon had ruptured. The results were very good in 42, good in 32, and poor in 43, but in 36 patients a long period of rest and reduction in sporting activity was necessary before a significant improvement was obtained. Operation was carried out on 16 patients (19 knees), 18 were in stage 3 and one in stage 4. Various surgical techniques were used. The results were very good in 7 knees, good in 5 and poor in 7. Operation is indicated after the failure of conservative measures and in patients who do not want to reduce their sporting level. The aim should be to induce healing at the bone tendon junction. We emphasize the importance of the prevention of jumper's knee in athletes.

Arthroscopy in the diagnosis and treatment of meniscal lesions of the knee associated with chronic ligamentous instability.

The role of arthroscopy in the diagnosis and treatment of meniscal lesions of the knee associated with chronic ligamentous instability is discussed and illustrated. Clinical examination and meticulous objective tests are usually sufficient to enable the surgeon to arrive at a correct assessment of the ligamentous instability, but in the associated meniscal lesion arthroscopy plays an important role in disclosing the site, extent and type of the lesion. This may be such that it is amenable to repair by subsequent open operation. However, if this is not the case, arthroscopic removal of such parts of the damaged meniscus as may be necessary to relieve symptoms can be carried out without risk of aggravating the instability by interfering with the healthy peripheral parts of the meniscus. The ideal treatment of selected cases is illustrated in an analysis of 35 such patients selected from a total case material of 456 patients including 116 arthroscopies during the same period. They have been classified into two clinical groups in which the treatment is discussed and the results reported.
