Anterior Cruciate Ligament Reconstruction Using Bone-Patella Tendon-Bone Autograft With Press-Fit Femoral Fixation: The Original Chambat Technique.

Patellar tendon grafts have long been considered the gold standard for anterior cruciate ligament reconstruction (ACLR). This Technical Note describes ACLR using bone-patella tendon-bone (BPTB) autograft with press-fit femoral fixation using an outside-in drilling technique.

Implant survival of 3rd-condyle and post-cam posterior-stabilised total knee arthroplasty are comparable at follow-up > 10 years: a systematic review.

Purpose: To summarise the literature on 3rd-condyle total knee arthroplasty (TKA) designs and compare their survival rates to those of post-cam TKA designs. The null hypothesis was that 3rd-condyle TKAs would have equivalent survival rates compared to contemporary post-cam TKAs.

Methods: An electronic literature search for Level I-V studies was independently conducted by two researchers using Medline and Web of Science for studies published between January 1984 and October 2020 that specifically reported on rates of implant survival and complications, joint kinematics, clinical outcomes, and radiographic outcomes of 3rd-condyle TKA.

Validation of a Composite Test for Assessment of Readiness for Return to Sports After Anterior Cruciate Ligament Reconstruction: The K-STARTS Test.

Background:: There is limited information on the appropriate timing of return to sports after anterior cruciate ligament (ACL) reconstruction. A composite test was developed to assess the athlete's ability to return to sports after ACL reconstruction: the Knee Santy Athletic Return To Sport (K-STARTS) test.

Hypothesis:: The K-STARTS test meets validation criteria for an outcome score assessing readiness for return to sports after ACL reconstruction.

Extension deficit after ACL reconstruction: Is open posterior release a safe and efficient procedure?

Background: Extension loss is a potentially devastating consequence of anterior cruciate ligament reconstruction (ACLR). It can often be treated by anterior arthroscopic release. In rare cases, a chronic flexion contracture requires an additional posterior open release.

Return to Sport Among French Alpine Skiers After an Anterior Cruciate Ligament Rupture: Results From 1980 to 2013.

Background: There is little known about return to sport and performance after anterior cruciate ligament (ACL) tear in high-level alpine skiers.

Purpose: To analyze the parameters that influence the return to sport and performance after an ACL tear in French alpine skiers from 1980 to 2013.

Study Design: Descriptive epidemiology study.

Partial tearing of the anterior cruciate ligament: diagnosis and treatment.

Partial tears of the anterior cruciate ligament (ACL) are common and represent 10-27% of the total. The main reasons for attending to cases of non-torn bundles are biomechanical, vascular and proprioceptive. Continued presence of the bundle also serves as protection during the healing process.

Bilateral custom-fit total knee arthroplasty in a patient with poliomyelitis.

In limbs affected by poliomyelitis, total knee arthroplasty results in satisfactory pain relief. However, the risk of failure is high, especially if the preoperative quadriceps power is low. Therefore, treating osteoarthritis in the current patient represented a challenging procedure.

Clinical and radiographic results of arthroscopic partial lateral meniscectomies in stable knees with a minimum follow up of 20 years.

Purpose: The purpose of this retrospective multicentric study was to evaluate the long-term effects of lateral meniscectomy and to identify those patients who are at the most risk of developing osteoarthritis (OA).

Methods: Eighty-nine arthroscopic partial lateral meniscectomies in stable knees with a mean follow-up of 22 ± 3 years were included. The following influencing factors were analyzed: age, sex, body mass index (BMI), physical activity, alignment, the types of meniscal lesions, the extent of meniscal resections and the initially associated cartilage lesions.

Proximal Tibial Anterior Closing Wedge Osteotomy in Repeat Revision of Anterior Cruciate Ligament Reconstruction.

Background: Physicians should consider an increased posterior tibial slope (PTS) as a risk factor for graft failure when proposing anterior cruciate ligament (ACL) re-revision.

Purpose: To describe the surgical technique of combined ACL revision and proximal tibial anterior closing wedge osteotomy and to evaluate its clinical outcome in cases of recurrent graft failure with associated increased tibial slope.

Study Design: Case series; Level of evidence, 4.

Rapid chondrolysis of the knee after partial lateral meniscectomy in professional athletes.

Background: Postoperative knee joint chondrolysis is a rare but serious complication. The aim of our study is to report the clinical presentation, the early, mid and long-term outcomes of rapid chondrolysis after a partial lateral meniscectomy in elite athletes.

Methods: Clinical records of 10 consecutive cases of rapid chondrolysis after partial lateral meniscectomy in eight professional athletes were retrospectively reviewed.

Arthrosis of the knee in chronic anterior laxity.

Arthrosis following rupture of the anterior cruciate ligament has been analysed in two series. The first series was derived from a review of 150 cases of reconstruction of the anterior cruciate ligament with a follow-up of 3 years or more. Arthrosis was seen to have developed in 13.

ACL tear.

Anterior cruciate ligament (ACL) reconstruction has evolved considerably over the past 30 years. This has largely been due to a better understanding of ACL anatomy and in particular a precise description of the femoral and tibial insertions of its two bundles. In the 1980s, the gold standard was anteromedial bundle reconstruction using the middle third of the patellar ligament.

High lateral portal for sparing the infrapatellar fat-pad during ACL reconstruction.

During arthroscopic ACL reconstruction, intra-articular visualization can be compromised by the interposition of the infrapatellar fat pad (IPFP) between the scope and the notch. In this technical note, we describe our technique of using lateral higher arthroscopic portal, starting arthroscopy with the resection of the ligamentum mucosum and performing the tibial tunnel in 40° of knee flexion to optimise the intra-articular view without IPFP debridement. This technique was performed in 112 consecutive arthroscopic ACL reconstructions and compared to that in the previous 112 cases in which a conventional method was used.

The influence of the tibial slope and the size of the intercondylar notch on rupture of the anterior cruciate ligament.

It has been suggested that an increased posterior tibial slope (PTS) and a narrow notch width index (NWI) increase the risk of anterior cruciate ligament (ACL) injury. The aim of this study was to establish why there are conflicting reports on their significance. A total of fifty patients with a ruptured ACL and 50 patients with an intact ACL were included in the study.

Prevalence of septic arthritis after anterior cruciate ligament reconstruction among professional athletes.

Background: Septic arthritis of the knee after anterior cruciate ligament (ACL) reconstruction is a rare complication. Its prevalence and characteristics have never been reported among professional athletes.

Purpose: To report the prevalence and the characteristics of septic arthritis after ACL reconstruction in professional athletes and a general population of patients.

Meniscal ossicle in a professional soccer player.

Meniscal ossicles are an unusual finding and a rare cause for knee pain. They are often initially diagnosed as a loose body, chondrocalcinosis or meniscal calcification within the knee joint. Few cases have been reported in the literature.

Activity level recovery after arthroscopic PCL reconstruction: a series of 21 patients with a mean follow-up of 29 months.

Surgical treatment of PCL tears is often indicated after conservative management failure and it is known to be challenging with unpredictable outcomes. This study aims to describe and to evaluate the outcome of an arthroscopic PCL anterolateral bundle reconstruction using a quadriceps tendon autograft. Our hypothesis is that knee stability and function can be restored using this technique allowing patients to resume their pre-injury level of activity.

Biologically enhanced ACL reconstruction.

Biological integration of the tendon graft is a crucial prerequisite for successful ACL reconstruction. Histological studies showed that the human ACL remnants contain a cellular capacity for healing potential. The goal of this technical note is to describe an ACL reconstruction technique, using ACL remnants as a biological sleeve for the graft.

Clinical and operative characteristics of cyclops syndrome after double-bundle anterior cruciate ligament reconstruction.

Purpose: The purpose of this study was to investigate the clinical and operative characteristics of cyclops lesion in a consecutive series of patients with anterior cruciate ligament (ACL) double-bundle reconstruction.

Methods: Included were 387 patients who underwent an ACL double-bundle reconstruction with quadriceps or hamstring tendons and were followed up at 6 weeks and 3, 6, and 12 months for clinical examination. When a persistent extension deficit was observed 3 months postoperatively, magnetic resonance imaging was performed to eventually diagnose a cyclops syndrome, and arthroscopic removal of the nodule was performed in these cases.

Preoperative factors correlating with prolonged range of motion deficit after anterior cruciate ligament reconstruction.

Background: Impaired postoperative range of motion remains one of the most frequent complications after anterior cruciate ligament reconstruction.

Purpose: This study was undertaken to determine the preoperative factors associated with prolonged range of motion deficit after anterior cruciate ligament reconstruction.

Study Design: Cohort study; Level of evidence, 3.

Isolated posterior cruciate ligament reconstruction: is non-aggressive rehabilitation the right protocol?

Introduction: Reconstruction Surgery of the posterior cruciate ligament (PCL) has not yet been fully standardized, and associated rehabilitation protocols have not been clearly defined. The aim of this study is to report the results of a consecutive series of patients who underwent the same surgical technique for isolated PCL reconstruction and were submitted to the same specific rehabilitation protocol. A non-aggressive rehabilitation protocol which protects the graft from excess mechanical stress produces satisfying and reproducible clinical and laxity results in the knee.

Selective anteromedial bundle reconstruction in partial ACL tears: a series of 36 patients with mean 24 months follow-up.

The purpose of this study was to describe an original technique of reconstruction of the anteromedial bundle preserving the posterolateral bundle and to report the results of a consecutive 36 patients series with mean 24 months follow-up. Our hypothesis is that this selective reconstruction of ACL partial tears could restore knee stability and function. In a consecutive series of 256, ACL reconstructions, 36 patients in which intact ACL fibers remained in the location corresponding to the posterolateral bundle were perioperatively diagnosed.
