Lateral ligament injuries of the knee

Abstract

Between 1982 and 1994 28 patients were treated for acute lateral knee ligament injuries; 25 patients, with a median age of 25.5 (range 16-75) years at injury, appeared for follow-up. Seven patients had isolated injury of the lateral collateral ligament/capsular structures, the remaining 19 patients had concomitant ligament injuries in the knee. Eight patients were treated conservatively, 1 with plaster immobilization and 7 with early mobilization. Eighteen patients underwent surgery, 17 of these within 3 weeks of injury. Repair/reconstruction of the cruciate ligaments was done at the same time as the lateral collateral ligament repair in 10 patients. At follow-up after a median of 7.5 years (range 6 months to 13 years), 11 had no varus instability, 7 had 1+, 5 had 2+, and 2 patients had 3+ varus instability. All patients with a final result of 2+ or 3+ had combined ligament injuries. The surgically treated lateral collateral ligament injuries all had a primary instability of 2+ or more. These patients showed an improvement in varus instability from a mean of 2.83+ preoperatively to a mean of 1.17+ postoperatively. Two-thirds of the surgically treated patients were stable or had a 1+ instability at follow-up. One conservatively treated patient with a 2+ varus instability and 1 with 1+ showed no improvement. Five conservatively treated patients with initial varus instability of 1+ were stable at follow-up. One patient with a 1+ varus instability had anterior cruciate ligament (ACL) rupture. He had a primary ACL reconstruction without lateral repair. He had no varus instability at follow-up. Our study supports the notion that operation performed at an early stage in fresh injuries with a varus instability of 2+ or more gives improved stability as a final result. Conservative treatment may not be expected to give an improved stability, but is sufficient in mild varus instability (1+) without additional cruciate ligament injuries.

Is PLC repair of a peel-off femoral lesion an effective option in a multiligament setting?

“…The mean follow-up was 16 months (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24). Normal distribution of the data has been verified for all the evaluated data except for preoperative posterior displacement.…”

Injuries of the Knee

“…In grade 3 sprains, particularly when other structures such as the ACL or PCL are damaged, surgery may be needed to prevent future instability. This may involve suturing or stitching the torn ends of the LCL or reconstructing the ligament with a part of a tendon, e.g., hamstrings tendon (Krukhaug et al 1998 ).…”

Die isolierte Bizepssehnenruptur am Kniegelenk

“…Eine Zusatzverletzung der Bizepssehne in diesem Verletzungsmuster ist zudem die Ausnahme [11]. Dennoch gehen Verletzungen der Bizepssehne normalerweise mit akuten Verletzungen der lateralen Bänder des Kniegelenks einher.…”
