AI Article Synopsis

  • The posterior oblique ligament (POL) is a key structure in the knee's posteromedial corner and helps stabilize against various forces.
  • Injuries to this area often occur with ACL injuries, leading to issues like anteromedial rotatory instability.
  • A surgical technique developed by Hughston in 1973 treats these injuries by reinforcing the POL and may involve adjusting the semimembranosus tendon to enhance knee stability without needing a tendon graft from other areas.

Article Abstract

The posterior oblique ligament (POL) is the main component of the posteromedial corner (PMC) of the knee and plays a crucial role in acting as a secondary restraint against translation, rotation, and valgus forces. Injuries to the PMC often occur in association with acute or chronic deficiency of the anterior cruciate ligament and may result in anteromedial rotatory instability. A surgical technique for treatment of acute and chronic injuries of the posteromedial structures was first established by Hughston in 1973. This procedure involves an advancement and reefing of the POL and adherent posterior capsule to the stout tissue of the intact medial collateral ligament, potentially using suture anchors if the POL tissue is detached from bone. Additionally, in cases of residual laxity, the semimembranosus tendon may be advanced anteriorly to improve dynamic stabilization. This procedure appears to be useful in cases of moderate posteromedial insufficiency and avoids retrieval of a medial tendon graft from the region of the medially stabilizing hamstrings or from the healthy contralateral side.

Varus posteromedial rotatory instability (VPMRI) of the elbow is one of the complex elbow instability. The primary sites of injury encompass fractures of the anteromedial coronoid process and injuries to the lateral collateral ligament of the elbow. Some patients may present with involvement of the medial collateral ligament of the elbow.

Purpose: Varus posteromedial rotatory instability (VPMRI) involves anteromedial coronoid fracture (AMCF), lateral ulnar collateral ligament (LUCL), and medial collateral ligament (MCL) injury. There is no general consensus regarding the surgical treatment, but most surgeons recommend internal fixation of the coronoid along with primary ligament repair. This methodology involves postoperative immobilization to allow ligament healing, occasionally associated with stiffness.

Anterolateral rotatory instability of the elbow: a possible etiology of primary osteoarthritis.

Clin Shoulder Elb

December 2024

Department of Orthopedic Surgery, Haeundae Paik Hospital, College of Medicine, Inje University, Busan, Korea.

Background: The purpose of this study is to describe anterolateral rotatory instability (ALRI) as a possible etiology of primary osteoarthritis (OA) of the elbow.

Methods: We examined 76 fresh frozen cadaveric elbows (male:female, 56:20; mean age, 81 years) for patterns of cartilage erosion that could be due to ALRI. These included erosions on the lateral trochlear ridge (LTR) lesion, crescent rim of the radial head (RC) lesion or the ventral capitellum (VC) lesion.

Article Synopsis
  • * The surgical technique involved single-bundle reconstruction of the posterior cruciate ligament with quadriceps tendon autograft and a modified method for reconstructing other ligaments based on the patient's condition.
  • * Early results from 10 patients showed promising functional scores and light pain levels, although there was a noted decrease in quality of life based on SF-12 scores.

Article Synopsis
  • Injuries to the knee's ligaments, especially the superficial medial collateral ligament (sMCL), can make the knee move too much in certain ways, which isn't good.
  • The study aimed to see if a special surgery could help fix these knee movement problems by reconstructing the injured ligaments.
  • After testing on knee samples, they found that the surgery successfully restored the knee’s movements to normal levels, just like a healthy knee.
