[Reinforcement of freshly glued or sutured rupture of the anterior cruciate ligament using the semitendinous tendon. Indications and early results].

Inopportune rupture forms deteriorate the prognosis after reconstructive operations on the anterior cruciate ligament. In order to improve the treatment results, we apply fibrin glue on intraligamentous ruptures and reinforce the reconstruction result with a distally fixed semitendinosus tendon graft. In old ruptures with beginning degenerative changes on the rupture stumps we refix the rest of the cruciate ligament as a posterolateral ligament part through transosseous sutures and also use the semitendinosus tendon as a reinforcement graft. 19 of the 26 cruciate ligaments treated in this way were stable at the reexamination which took place 9 months after the operation on a average. 7 remaining instabilities are due to degenerative changes of both the tendon graft and the reconstructed rests of the cruciate ligaments: this could be proved by CT-studies. Using a tendon graft in combination with alloplastic materials ought to improve the postoperative results in future.

[Cartilage adhesion on the knee joint. Clinical follow-up].

During the years 1979 to 1982, 34 cartilage adhesion with fibrin were performed in the knee joint. 29 patients could be re-examined. 21 patients additionally underwent a control arthroscopy. Analyzation of the results showed that the prognostical outlook after a replantation of old cartilage fragments into a degeneratively affected fracture bed must be considered as poor. Better results were achieved when the cartilage lesion could be treated in a fresh state.

[Experiences with Weber's subcapital rotation osteotomy in recurrent shoulder dislocation].

In 23 patients suffering from recurrent posttraumatic dislocation of the shoulder joint the derotation of the humeral head was performed as described by Weber. A description of the operative technique is given. As recommended by Weber an angled 1/2-tubular plate with 7 holes was used for stable osteosynthesis 17 times. After movement treatment removal of the osteo-synthesis-material was possible 6 to 8 months later. Because of high absence of recidivity with repair of full mobility and full strength the derotation of the humeral head is a treatment of choice in cases of recurrent posttraumatic dislocation of the shoulder joint.

[Injuries of the posterior end of the medial meniscus and the posterior oblique ligament. Classification and therapy].

Meniscectomy undoubtedly leads to arthrotic degeneration in the knee joint. This can be proven by X-ray technique. It is especially the resection of the medial meniscus which increases the anteromedial instability of the knee joint. It is important therefore to preserve a meniscus whenever this is possible. The resection or partial resection of a medial meniscus showing a lesion in loco classico is still indicated. If, however, a meniscus is only marginally detached from its fixation to the lig. collaterale mediale posterior a carefully carried out reinsertion of the medial meniscus has proven to be appropriate. It is on one hand the vascular supply of the base of the meniscus which indicates a reinsertion, on the other hand an anteromedial instability of the knee joint can be compensated by a reinsertion.

[Reconstruction of fresh and old ligament injuries of the proximal thumb joint].

In fresh ruptures of the collateral ligaments of the proximal thumb joint conservative therapy often fails; therefore these lesions ought to be operated. A reinsertion of the ligaments which at the most part are torn out at their distal end, using the suture described by Lengemann, proved successful in 16 cases. At old ligament lesions we used the palmaris longus tendon as a ligament-substitute. 6 patients operated according to this method were completely painless at the reexamination which took place on an average 8 months after the operation.

[Therapy for recent and old injuries of the fibular capsular ligament in the ankle joint].

Fresh injuries of the fibular capsule-ligament-complex in the age in which physical competition takes place must be treated surgically. To achieve optimal postoperative results, the different forms of ruptures of the fibular ligaments must be treated in a differentiated way. A reconstruction of the Lig. talofibulare anterius generally succeeds without trouble, whereas a reconstruction of the Lig. calcaneofibulare often requires a plastic replacement by a periostal flap. At old ruptures, however, the tendon plastic is the safest way of reconstructing the stability of the ankle. The distally stalked tendon graft has several advantages, especially when the graft is attached in accordance with the anatomy of the fibular ligaments.
