ABSTRACT

This technical note aimed to present a straigthforward method for harvesting quadriceps tendon autografts with the use of a simple vaginal speculum and direct visualisation of a scope. Anterior cruciate ligament reconstruction with quadriceps tendon autografts has gained popularity in recent years, with many harvesting techniques that use different harvesting systems available on the market. These techniques vary from transverse to longitudinal skin incisions and from open to minimally invasive approaches and have a learning curve, as with the majority of surgical procedures. The technique proposed in this technical note is minimally invasive, can be easily reproduced by any surgeon irrespective of their experience, has a short learning curve, requires no additional cost or technical support during the procedure and creates a stable working space that allows for freedom of manipulation of surgical instruments and the arthroscope.

ABSTRACT

PURPOSE: The present study aims to report the arthroscopic, radiological and clinical appearance of a rare anatomical variation of a hypertrophied medial parapatellar plica with its response to arthroscopic treatment. CASE PRESENTATION: A 14-year-old female handball athlete presented with a history of left knee injury during her participation in a handball training session and subsequent locked knee at 20º flexion. Tenderness was located at the medial joint line. Plain radiographs of the injured knee were normal. The magnetic resonance imaging revealed a hypertrophic medial parapatellar plica and a horizontal tear of the medial meniscus. A standard knee arthroscopy was performed. An extremely hypertrophied medial plica was identified, covering a great part of the medial femoral condyle extending up to the femoral trochlea. Distally, it was attached into the inter-meniscal ligament. The plica was excised and the medial meniscus tear was repaired. At 1-month post-operatively, the patient was completely asymptomatic and at 3-months she returned to her weekly training routine. CONCLUSIONS: This study presented a rare anatomical variation of a hypertrophied medial parapatellar plica with atypical course in the medial patellofemoral compartment and insertion into the inter-meniscal ligament. In combination with a medial meniscus tear led to a locked knee. Arthroscopic medial meniscus repair and plica excision resulted in complete resolution of symptoms.

ABSTRACT

This technical note describes a simple arthroscopic technique that was introduced without the need for further staff during an operation to address osteonecrosis of the medial femoral condyle. A 2.4 mm pin was positioned through the sleeve of an anterior cruciate ligament (ACL) tibial guide and marked with a steri-strip at its body, aiming at 5-10 mm distance between the tips of guide and the pin. The steri-strip serves as a marker and as a stop for inadvertent violation of the cartilage. The tip of the ACL was positioned just over the bone lesion, while the marked 2.4 mm pin was inserted through the ACL tibial guide from anterior surface of the femur. A stab incision was made and without advancing the sleeve to the bone, the pin was drilled to the marked position while cartilage integrity was confirmed arthroscopically. This arthroscopic technique is simple, fast and effective and is performed without the need for special equipment.

ABSTRACT

Persistent rotatory instability after anterior cruciate ligament (ACL) reconstruction has been well studied and recognized as the cause of unsatisfactory clinical results. Various anterolateral techniques have been described as an adjunct to the ACL reconstruction to improve clinical outcomes. Modified deep Lemaire lateral extra-articular tenodesis has been tested both biomechanically and clinically and proved an efficient solution in controlling tibia internal rotation, when performed in conjunction with ACL reconstruction. We describe a simple, versatile, effective, and reproducible technique of lateral extra-articular tenodesis, using common suspensory femoral fixation, with no additional cost and surgical risk.

ABSTRACT

We present a case of a chondral lesion after anterior cruciate ligament (ACL) reconstruction caused by femoral cross-pin breakage and intra-articular migration of the fragment. A 20-year-old man initially underwent ACL reconstruction using a hamstring autograft. The RigidFix bioabsorbable cross-pin (DePuy Mitek) was used for the femoral fixation. The patient returned to a pre-injury level of activity (professional soccer player) 6 months postoperatively. However, 20 months postoperatively, the patient presented with effusion and lateral joint-line pain after practice, without signs of instability in clinical examination. Conservative treatment failed and at re-arthroscopy a chondral lesion of the lateral femoral and tibial condyle was found, which had been caused by the broken femoral cross-pin. The fragment was removed and the symptoms resolved. Orthopaedic surgeons should be aware of this complication when using a bioabsorbable cross-pin for femoral fixation in ACL reconstruction.

ABSTRACT

Spontaneous, bilateral, quadriceps tendon rupture is a rare injury. Many predisposing conditions have been reported that contribute to quadriceps tendon degeneration. We report a case of a 42-year-old farmer with spontaneous, bilateral, quadriceps tendon rupture and clear medical history. Clinical and laboratory investigations revealed no risk factors for tendon degeneration but the patient reported that he was exposed locally to methidathion 1 week before the rupture. Methidathion is an organophosphate insecticide commonly used in agriculture that is highly toxic via the dermal route. Methidathion induces lipid pre-oxidation and consequently alters quadriceps tendon blood supply and ultrastructure. The injury was treated with early surgical repair and final outcome was excellent 44 months postoperatively.

ABSTRACT

The RigidFix Cross Pin System (DePuy Mitek, Raynham, MA) is a popular technique for femoral fixation of graft in ACL reconstruction. In some cases, though, cross pins miss the femoral tunnel resulting in inadequate proximal graft fixation. We present a simple test to detect the incorrect placement of cross pins. The pinholes are drilled through the guide frame, leaving 2 sleeves for cross pins insertion. The manufacturer's recommendations, at this stage, are to reinsert the femoral tunnel guidewire, remove the guide frame, and insert the graft without verifying accurate pinhole positioning. We reinsert the femoral tunnel guidewire without removing the guide frame, and a second guidewire is introduced through each of the sleeves in turn. In case of appropriate pinhole placement, the 2 guidewires will meet in the cannulated rod of the guide frame and the surgeon will have the metal-to-metal feeling. If the pinhole misses the femoral tunnel, the 2 guidewires will not meet and the surgeon will not have the metal-to-metal feeling. In our practice, 9 cases of inaccurate pinhole placement were detected with this test and verified by direct vision of the femoral tunnel with the arthroscope. We find this test simple, reliable, and not time consuming.
