[Chronic anteromedial and anterolateral instability of the knee in athletes. Results of treatment with peripheral surgery].

The authors have treated 48 unstable knees by lateral and medial ligament plasties using the Hughston technique. 36 patients were athletes who had to cease their sport because of anteromedial or anterolateral instability. 8 had previously had a menisectomy. Forty-three patients were reviewed with a follow up of 15 to 60 months. 30 patients who had both an active and a passive ligament plasty were able to undertake sporting activities but only 12 at top level. There were 13 failures.

Jumper's knee.

The authors present a clinical study on twenty six cases of a painful syndrome affecting the distal quadriceps tendon complex, popularly known as "jumper's knee". They review the diagnostic aspects and discuss the treatment. In particular, they suggest a surgical approach that is not limited to the inflammatory or degenerative component of the syndrome, but also aims to correct imbalance of the extensor apparatus.

Detachment of the accessory fragment in "patella partita".

The authors report six cases of detachment of the accessory fragment in "patella partita". This lesion is often unrecognised, especially among athletes. It gives rise to painful symptoms that are at first severe and later less marked. These symptoms disappear completely in both acute and chronic cases with the removal of the detached accessory fragment.

Subcutaneous rupture of the Achilles tendon.

A series of 27 ruptures of the tendo Achillis are reported. Samples of tendon tissue, taken both at the site of rupture and at a distance from it, were histologically examined. Four different surgical procedures were performed. All patients showed marked degenerative changes of the tendon tissue. No definite relationship was found between the surgical procedure employed and functional results obtained. These were rated as excellent in 12 cases, good in 11 and fair in four. Only minor complications attending the operation occurred. We emphasize the superiority of open repair over conservative treatment.

Intracellular collagen fibres in regenerating tendon.

Intracytoplasmic collagen fibres contained in elongated membrane-bound structures were observed in fibroblasts of regenerating tendon in the later stages of the repair process. The observations appear to support the hypothesis that collagen fibres of the intercellular matrix may be phagocytosed by the cells and degraded in the intracellular environment. Phagocytosis of extracellular collagen fibres probably represents an additional mechanism of collagen resorption during the later stages of remodelling of the regenerating tendon.

Overuse tendon conditions: time to change a confusing terminology.

In overuse clinical conditions in and around tendons, frank inflammation is infrequent, and is associated mostly with tendon ruptures. Tendinosis implies tendon degeneration without clinical or histological signs of intratendinous inflammation, and is not necessarily symptomatic. Patients undergoing an operation for Achilles tendinopathy show similar areas of degeneration. When the term tendinitis is used in a clinical context, it does not refer to a specific histopathological entity. However, tendinitis is commonly used for conditions that are truly tendinoses, and this leads athletes and coaches to underestimate the proven chronicity of the condition. Paratenonitis is characterized by acute edema and hypermia of the paratenon, with infiltration of inflammatory cells, possibly with production of a fibrinous exudate that fills the tendon sheath, causing the typical crepitus that can be felt on clinical examination. The term partial tear of a tendon should describe a macroscopically evident subcutaneous partial tear of a tendon, an uncommon acute lesion. Most articles describing the surgical treatment of 'partial tears' of a given tendon in reality deal with degenerative tendinopathies. The combination of pain, swelling, and impaired performance should be labeled tendinopathy. According to the tissues affected, the terms tendinopathy, paratendinopathy, or pantendinopathy should be used.

Method for reconstruction of the anterior cruciate ligament using the semitendinosus tendon.

There is still considerable difference of opinion as to the advisability of reconstructing the anterior cruciate ligament in chronic rotatory instability. This paper presents a simple method of anterior cruciate reconstruction using the semitendinosus tendon in 12 cases of chronic combined anteromedial-anterolateral rotatory instability along with preliminary results. In all cases the reconstruction of the anterior cruciate was associated with extraarticular reconstruction. Posterior oblique ligament and semimembranosus advancement was used for the medial compartment and biceps advancement for the lateral compartment. The initial results, with an average followup of 8 months, showed an anterior drawer sign with the tibia in neutral rotation of less than 1+ in all cases compared to a previous series in which, at the same point in time, 36 of 42 patients had a 2+ drawer sign and 6 had a 3+. There has been inadequate time for evaluation of the long-term results. Further comparison with longer followups are needed to determine how well this type of anterior cruciate ligament reconstruction works for extraarticular reconstructions.

Hemathrosis treated by aspiration and casting. How to condemn the knee.

Eighty-eight athletes treated for an acute hemarthrosis of the knee without any demonstrable ligament tear were evaluated. Analysis of the clinical data from these cases, all treated between 1970 and 1975 with aspiration and casting, revealed that the injury was apparently worse than had been thought at the time of first treatment. Surgery was subsequently performed in 32 (37%) because of meniscus tear, and 28 demonstrated anterior cruciate ligament insufficiency. In the 56 who did not have surgical treatment, 38 (43% of the entire group) had significant symptoms and disability causing them to decrease sports participation, and only 18 (20% of the overall group) returned to sports without symptoms or disability. Objective findings at followup suggested that in 70% of the patients injury of the anterior cruciate ligament occurred during the original trauma. A precise diagnosis is needed in every knee ligament sprain with hemarthrosis before one decides upon conservative treatment such as aspiration and casting.

Jumper's knee.

Jumper's knee (patellar or quadriceps tendon tendonitis) is found in a high number of athletes, especially in volleyball and basketball players. Conservative treatment (rest, stretching, physical therapy and antiinflammatory drugs) is usually successful. The athletes often recover completely and resume their sports activity. The purpose of this study is to present the histologic findings and our surgical repair of 18 knees of patients who underwent surgery after failure of conservative treatment. Histologic findings confirm that the so-called "jumper's knee" is a pathology localized at the bone-tendon junction. In all cases the following abnormalities were found: pseudocystic cavities at the borderline between mineralized fibrocartilage and bone, disappearance of the "blue line," increased thickness of the insertional fibrocartilage with myxomatous and hyaline metaplasia, mineralization, and ossification of the fibrocartilage far from the "blue line." Abnormalities of the patellar tendon were observed only in one patient who received local injection of corticosteroids. Eleven of the 18 surgically treated knees obtained a satisfactory result with complete resumption of sports activity.
