Meniscal Repair for Radial Tears of the Midbody of the Lateral Meniscus
The American journal of sports medicine, 2010Co-Authors: Nam-hong Choi, Tae-hyung Kim, Kyung-mo Son, Brian N. VictoroffAbstract:BackgroundRadial meniscal tears historically have been treated by partial meniscectomy, although they are more biomechanically detrimental than longitudinal tears. Clinical results after meniscal repair for radial tears of the midbody of the lateral meniscus have been reported rarely.Study DesignCase series: Level of evidence, 4.MethodsFourteen consecutive patients who had radial tears of the midbody of the lateral meniscus underwent arthroscopic repair. Inclusion criteria were radial tears involving the red-red or red-white zone. All patients underwent all-inside meniscal repair using absorbable sutures. Postoperative evaluation was performed using joint-line tenderness, McMurray Test, range of motion, and follow-up magnetic resonance imaging (MRI) scan at 6 months postoperatively. Lysholm knee score and Tegner activity level were evaluated at last follow-up. In 4 patients, second-look arthroscopies were performed.ResultsThe average follow-up was 36.3 months. No patient had joint-line tenderness. Three p...

Anterior horn tears of the lateral meniscus in soccer players.
Arthroscopy: The Journal of Arthroscopic & Related Surgery, 2006Co-Authors: Nam-hong Choi, Brian N. VictoroffAbstract:Purpose: The purpose of this retrospective study was to define the clinical and arthroscopic characteristics of anterior horn tears of the lateral meniscus. Type of Study: Case series. Methods: Fourteen patients with mean age of 20.2 years were enrolled in this institutional review board–approved study. All patients were soccer players with tears of the anterior horn of the lateral meniscus. All patients underwent physical examinations, magnetic resonance imaging (MRI), and arthroscopic treatment. Results: Common symptoms were a catching sensation in 10 patients (71.4%), pain at squatting in 9 patients (64.3%), and sense of giving way and effusion, each in 7 patients (50%). Five patients (35.7%) had lateral joint-line tenderness. McMurray's Test was positive in 6 (42.9%) and tears were diagnosed by MRI in 13 (92.8%) patients. Arthroscopic examination showed multiple longitudinal tears in the avascular white zone of the meniscus in 7 patients (50%). Conclusions: These data show that the McMurray Test and joint-line tenderness had a low diagnostic value in diagnosing anterior horn tears of the lateral meniscus. MRI, however, had a high diagnostic value. Common arthroscopic findings included multiple longitudinal tears within the white zone of the anterior horn. Level of Evidence: Level IV.

A ganglion of the anterior cruciate ligament causing erosion of the lateral femoral condyle: a case report.
The Journal of bone and joint surgery. American volume, 2002Co-Authors: Nam-hong Choi, Sung-jae KimAbstract:Cystic lesions around the knee are usually either meniscal cysts or popliteal cysts. Intra-articular ganglia of the knee are uncommon 1. Ganglia arising from cruciate ligaments have rarely been reported 2. In the cases that have been reported, ganglion cysts produced vague knee discomfort but sometimes they also produced mechanical symptoms suggestive of a meniscal tear or a positive finding with the McMurray Test 3,4. The present report describes a patient who had a large ganglion cyst that was adjacent to the anterior cruciate ligament and enclosed in a common sheath and that had eroded the medial aspect of the lateral femoral condyle. An eighteen-year-old girl presented with a three-year history of progressively increasing pain in the right knee. She stated that there had been no prior trauma to the knee. She reported a deep ache in the knee that was aggravated by activity, especially squatting. There was no catching, swelling, or sense of giving-way. Physical examination revealed a full range of motion and negative findings on the Lachman and pivot-shift Tests. There was no swelling or tenderness along the joint line. The findings on radiographs of …

Arthroscopic meniscal repair: a comparative study between three different surgical techniques
Knee Surgery Sports Traumatology Arthroscopy, 2006Co-Authors: Michael E. Hantes, Vasilios C. Zachos, Sokratis E. Varitimidis, Zoe H. Dailiana, Theophilos Karachalios, Konstantinos N. MalizosAbstract:The purpose of this prospective study was to evaluate and compare the results of arthroscopic meniscal repair using three different techniques. Between January 2002 and March 2004, 57 patients who met the inclusion criteria underwent an arthroscopic meniscal repair. The outside-in technique was used in 17 patients (group A), the inside-out in 20 patients (group B), while the rest of the 20 patients (group C) were managed by the all-inside technique using the Mitek RapidLoc soft tissue anchor (Mitek Surgical Products, Westwood, MA, USA). Anterior cruciate ligament (ACL) reconstruction was performed in 29 patients (51%). The criteria for clinical success included absence of joint line tenderness, locking, swelling, and a negative McMurray Test. The minimum follow-up was one year for all groups. The mean follow-up was 23 months for group A, 22 months for group B, and 22 months for group C. All meniscal repairs were considered healed according to our criteria in group A, while 19 out of 20 repairs (95%) healed in group B. Finally 7 of 20 repairs (35%) were considered failures in group C and this difference was statistically significant in comparison with other groups. The time required for meniscal repair averaged 38.5 min for group A, 18.1 min for group B, and 13.6 min for group C. Operation time for meniscal repair in group A was statistically longer in comparison with other groups. There were no significant differences among the three groups concerning complications. According to our results, arhtroscopic meniscal repair with the inside-out technique seems to be superior in comparison with the other methods because it offers a high rate of meniscus healing without prolonged operation time.

THESSALY Test: DIAGNOSTIC ACCURACY OF A NEW CLINICAL Test FOR EARLY DETECTION OF MENISCAL TEARS
2006Co-Authors: T.h. Karachalios, M. Hantes, A.h. Zibis, V. Zachos, A.h. Karantanas, Konstantinos N. MalizosAbstract:Background: Clinical Tests used for the detection of knee meniscal tears do not present acceptable diagnostic sensitivity and specificity values. Diagnostic accuracy is improved by arthroscopic evaluation or performing magnetic resonance imaging (MRI) Tests. The objective of this study was to evaluate the diagnostic accuracy of a new dynamic clinical examination Test for the detection of meniscal tears. Methods: Two hundred and thirteen symptomatic patients with recent knee injuries who all were clinically examined, had MRI Tests and underwent arthroscopic surgery and 197 asymptomatic volunteers who all were clinically examined and had MRI Tests of their normal knees were included in this study. For clinical examination the medial and lateral joint line tenderness Test, McMurray Test, Apley compression and distraction Test, Thessaly Test at 5° and Thessaly Test at 20° of flexion were used. For al clinical Tests sensitivity, specificity, negative predictive value and diagnostic accuracy rates were calculated against arthroscopic and magnetic resonance imaging data. Results: Thessaly Test at 20° of flexion showed a high diagnostic accuracy rate at the level of 94% and a low number of false negative recordings in detecting tears of both the medial and lateral meniscus. Other traditional clinical examination Tests, with the exception of joint line tenderness which presented a diagnostic accuracy rate of 88% in detecting lateral meniscal tears, showed inferior rates. Conclusions: Thessaly Test at 20° of flexion can be safely used as a first line screening clinical Test for the detection of meniscal tears reducing the need and the cost of modern magnetic resonance imaging methods.

Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the Internation, 2006Co-Authors: Elias S. Kotsovolos, Michael E. Hantes, Dimitrios S. Mastrokalos, Olaf Lorbach, Hans H. PaesslerAbstract:Purpose: The goal of this prospective study was to evaluate the results of arthroscopic meniscal repair using the FasT-Fix repair system. Type of Study: Prospective case series. Methods: Sixty-one meniscal repairs with the FasT-Fix meniscal repair system in 58 patients with a mean age of 32.6 years were performed between 2001 and 2002. Concurrent anterior cruciate ligament reconstruction was performed in 36 patients (62%). All tears were longitudinal and located in the red/red or red/white zone. Criteria for clinical success included absence of joint-line tenderness, locking, swelling, and a negative McMurray Test. Clinical evaluation also included the Tegner and Lysholm knee scores, and KT-1000 arthrometry. In addition, all patients were evaluated preoperatively with magnetic resonance imaging. Results: The average follow-up was 18 months (range, 14 to 28 months). Six of 61 repaired menisci (9.8%) were considered failures according to our criteria. Therefore, the success rate was 90.2%. Time required for meniscal repair averaged 11 minutes. Postoperatively, the majority of the patients had no restrictions in sports activities. The mean Lysholm significantly improved from 43.6 preoperatively to 87.5 postoperatively ( P Conclusions: Our results show that arthroscopic meniscal repair with the FasT-Fix repair system provided a high rate of meniscus healing and appeared to be safe and effective in this group of patients. Level of Evidence: Level IV, therapeutic study, case series (no control group).
