“…Noble and Erat reported that 20% of their 250 patients who were waiting for a meniscectomy did not need the operation, and of those that were operated on only 73% had significant meniscal abnormalities [20]. We do not advise arthroscopy in all acute injuries, unlike others [29].…”

Summary. The diagnostic accuracy of clinical examination for internal derangement of the knee were evaluated by arthroscopy in 195 patients (200 knees). Radiographs were available and 50 patients had magnetic resonance imaging. The clinical diagnosis was correct in 104 knees (52%), incomplete in 70 (35%) and incorrect in 26 (13%). When there was a single abnormality the diagnosis was correct in 70%, but when more than 3 lesions were discovered the figure was 28%. All individual lesions were diagnosed correctly in more than 90%. The lesions most difficult to diagnose were chondral fractures, partial tears of the anterior cruciate ligament and loose bodies. Knees with acute lesions and those with a single diagnosis were significantly easier to diagnose (p 50.01). Age, sex, MRI and the surgeon were not significant.

“…The posterior force recorded on the sheet was 137.9 N at 90°flexion and 134.9 N at 135°(average of three measurements). The posterior force applied to the knees was considered to be approximately 130 N at both flexion angles which was comparable to those of the methods using arthrometers or stress radiographs [5,13,23,26,27].…”

“…Much of what we know about posterior stability has been obtained using stress radiography and arthrometry for normal knees [5,11,13,23,26,27]. In the case of PCL reconstruction surgery, the tension of the graft is determined commonly by that of the contralateral side assessed by stress radiography or arthrometry.…”

Background Deep knee flexion is important to proper function for some activities and in some cultures, although there are large posterior forces during high knee flexion. Most of what we know about posterior restraint and stability, however, has not been determined from deep flexion and without distinguishing motion in the medial and lateral compartments. Questions/purposes We therefore evaluated (1) the difference in posterior displacement between the medial and lateral compartments at a commonly used flexion angle of 90°; (2) that of deeply flexed knees at 135°; and (3) the difference in kinematics in the medial and lateral compartments. We analyzed posterior stability in 21 normal knees using interventional open magnetic resonance imaging (MRI) system.

“…Secondly, we did not use any instrument to objectively evaluate the medial compartment opening and the external rotation. Literature is still controversial on the correlation between instrumental and manual clinical evaluations [1,23,29,32]. Third, while valgus stress X-rays can provide objective and reproducible measurements of medial compartment gaps [12], the external rotation test currently remains a manual and subjective evaluation.…”

Background Residual laxity remains after ACL reconstruction in patients with combined chronic ACL and medial instability. The question arises whether to correct medial capsular and ligament injuries when Grade II and III medial laxity is present. Description of Technique We developed a mini-invasive medial ligament plasty to repair the medial collateral ligament to correct residual medial valgus and rotatory laxity after ACL reconstruction. Patients and Methods We prospectively followed 36 patients with an ACL deficiency combined with chronic Grade II or III valgus and rotatory medial instability. The mean age was 37 years (range, 15-70 years).
