Combined chronic posterior cruciate and posterolateral corner ligamentous injuries: a comparison of posterior cruciate ligament reconstruction with and without reconstruction of the posterolateral corner.

Many have advocated the importance of correcting posterolateral rotatory instability (PLRI) in injuries causing rupture of the posterior cruciate ligament (PCL) and posterolateral corner. However, there have been few studies directly comparing the results of reconstructing the PCL in isolation with PCL reconstruction combined with stabilisation of the posterolateral corner. We report on a retrospective study into 17 consecutive patients with chronic combined posterior cruciate and posterolateral corner ligamentous injuries. The mean follow-up was 35 months (range 14-74 months). All patients had unstable knees, with significant PLRI. In 12 cases the PCL alone was reconstructed, in 5 cases a combined PCL and posterolateral corner reconstruction was performed. At a mean follow-up of 35 months, both groups had significantly improved compared to their pre-operative status, as measured by Lysholm and Tegner scores and clinical examination (P<0.01). The group in which only the PCL was reconstructed had significantly lower scores compared to those who had the additional posterolateral corner reconstruction (Tegner P<0.04, Lysholm P<0.02).

An arthroscopic technique for treating patients with frozen shoulder.

Forty-three patients with a diagnosis of primary or secondary frozen shoulder who had symptoms for an average of 12 months and failed conservative treatment of at least 12 weeks of physical therapy, were treated with an arthrosopic capsular release. On completion of standard shoulder arthroscopy, intra-articular cautery was used to completely divide the anterior-inferior capsule, the intra-articular portion of the subscapularis tendon, and the middle glenohumeral, the superior glenohumeral, and the coracohumeral ligaments. The subacromial space was inspected in all patients. Eighteen patients had extensive subacromial fibrosis that required debridement. Subacromial decompression was reserved for patients with evidence of an acromial spur seen at the time of arthroscopy. Postoperatively, all patients showed substantial gains in shoulder range of motion, as well as diminished shoulder pain. Thirty-five patients completed a telephone survey at an average of 22 months after surgery. The average modified shoulder score was 19 (scale, 13 to 65), with 83% of patients indicating that their shoulder was normal or caused only mild symptoms. In conclusion, the authors believe that arthroscopic capsular release is an effective and safe alternative to manipulation in patients with a recalcitrant frozen shoulder.

Congophilic substance with green dichroism in hip joints in autopsy material.

Cartilage and fibrous capsular tissue from the hip joints of 30 unselected autopsies have been examined for the presence of congophilic substance with green dichroism (CS-GD). Ninety-three per cent of the cases had CS-GD in the joint cartilage and 43 per cent contained amyloid deposits in the capsule. The relation of these substances to age and the relation of CS-GD to the upper and lower parts of the femoral head cartilage have been studied, as well as the inter-relationship between the presence of CS-GD in the cartilage and amyloid deposits in the capsule within each joint.

Lateral stabilizing structures of the knee: functional anatomy and injuries assessed with MR imaging.

The lateral aspect of the knee is stabilized by a complex arrangement of ligaments, tendons, and muscles. These structures can be demonstrated with routine spin-echo magnetic resonance (MR) imaging sequences performed in the sagittal, coronal, and axial planes. Anterolateral stabilization is provided by the capsule and iliotibial tract. Posterolateral stabilization is provided by the arcuate ligament complex, which comprises the lateral collateral ligament; biceps femoris tendon; popliteus muscle and tendon; popliteal meniscal and popliteal fibular ligaments; oblique popliteal, arcuate, and fabellofibular ligaments; and lateral gastrocnemius muscle. Injuries to lateral knee structures are less common than injuries to medial knee structures but may be more disabling. Most lateral compartment injuries are associated with damage to the cruciate ligaments and medial knee structures. Moreover, such injuries are frequently overlooked at clinical examination. Structures of the anterolateral quadrant are the most frequently injured; posterolateral instability is considerably less common. Practically all tears of the lateral collateral ligament are associated with damage to posterolateral knee structures. Most injuries of the popliteus muscle and tendon are associated with damage to other knee structures. MR imaging can demonstrate these injuries. Familiarity with the musculotendinous anatomy of the knee will facilitate accurate diagnosis with MR imaging.

[Value of computerized tomography and nuclear magnetic resonance tomography in preoperative diagnosis of meniscus lesions and ligamentous lesions of the knee joint].

In a prospective study, 53 patients with chronic complaints and acute injuries of the knee joint, were evaluated by clinical examination, CT-scanning and magnetic resonance imaging (MRI). Subsequently, arthroscopy or an open surgical procedure was performed. A total of 21 patients suffered from meniscal lesions. There were 17 ruptures of the medial and 4 ruptures of the lateral meniscus. In patients with meniscus ruptures, the sensitivity of both MRI and CT-scan was 86%, whereas the specificity of MRI was slightly lower than that of CT-scan. The accuracy and the predictive value were also slightly lower, although the difference was not significant. Fifteen patients suffered from acute or chronic ligament ruptures. In patients with anterior cruciate ligament (ACL) ruptures, all complete ACL ruptures had correctly been diagnosed by CT and MRI. Two out of four partial ACL ruptures were missed by MRI; only one was missed by CT-scan. Three medial collateral ligament ruptures were documented by MRI and two by CT-scanning. The high negative predictive value of CT and MRI can realize a reduction of the amount of diagnostic arthroscopies.

Contemporary magnetic resonance imaging of the knee. The orthopedic surgeon's perspective.

This article discusses the current applications of MR imaging in the practice of orthopedic surgery and sports medicine. When is MR imaging helpful to the treating surgeon, and when is it not? In what specific areas will future improvements in technical acquisition and interpretation be helpful in determining appropriate treatment? This article explores these questions.
