Anterior Closing Wedge Proximal Tibial Osteotomy for Slope Correction in Failed ACL Reconstructions

Abstract

Increased sagittal plane posterior tibial slope has been identified as a risk factor for primary anterior cruciate
ligament reconstruction (ACLR) failure. Although ACLR failure is multifactorial, correction of sagittal plane posterior tibial
slope should be evaluated in patients with an ACLR graft rupture. There are limited technical descriptions of proposed
decreasing tibial slope osteotomy procedures; therefore, the […]

Utilization of Transtibial Centralization Suture Best Minimizes Extrusion and Restores Tibiofemoral Contact Mechanics for Anatomic Medial Meniscal Root Repairs in A Cadaveric Model

Background:

Although posterior medial meniscal root (PMMR) repairs are often successful, postoperative meniscal extrusion after a root repair has been identified as a potential clinical problem.

Purpose/Hypothesis:

The purpose was to quantitatively evaluate the tibiofemoral contact mechanics and extent of meniscal extrusion after a PMMR repair. It was hypothesized that the addition of a centralization suture (into […]

Platelet-Rich Plasma for Patellar Tendinopathy: A Randomized Controlled Trial of Leukocyte-Rich PRP or Leukocyte-Poor PRP Versus Saline

Background:

A small number of randomized controlled trials have found ultrasound-guided injection of platelet-rich plasma (PRP) to be no more effective than saline for several tendinopathies; limited information exists for patellar tendinopathy. In addition, different PRP formulations that produce varying concentrations of leukocytes have not been directly compared for patellar tendinopathy.

Purpose/Hypothesis:

To determine if a single […]

Biomechanical Comparison of Vertical Mattress and Cross-stitch Suture Techniques and Single- and Double-Row Configurations for the Treatment of Bucket-Handle Medial Meniscal Tears

Background:

Given the variety of suturing techniques for bucket-handle meniscal repair, it is important to assess which suturing technique best restores native biomechanics.

Purpose/Hypothesis:

To biomechanically compare vertical mattress and cross-stitch suture techniques, in single- and double-row configurations, in their ability to restore native knee kinematics in a bucket-handle medial meniscal tear model. The hypothesis was that […]

Tibial Slope and Its Effect on Graft Force in Posterior Cruciate Ligament Reconstructions

Background:

A flattened posterior tibial slope may cause excessive unwanted stress on the posterior cruciate ligament (PCL) reconstruction graft and place patients at risk for PCL reconstruction graft failure. To date, there is a paucity of biomechanical studies evaluating the effect of posterior tibial slope on the loading properties of single-bundle (SB) and double-bundle (DB) […]

Fibular Collateral Ligament Reconstruction in Adolescent Patients

2019 Arthroscopy Journal

Fibular collateral ligament (FCL) injuries can present as lateral-sided knee pain with feelings of side-to-side instability during activity. Patients with FCL injuries can have accompanying symptoms related to irritation of the common peroneal nerve. Preoperative diagnosis is imperative and should include a thorough physical examination complemented with varus stress radiographs before surgical […]

Percutaneous Lengthening of a Regenerated Semitendinosus Tendon for Medial Hamstring Snapping

2019 Arthroscopy Journal

Snapping syndromes are caused by 2 adjacent anatomic structures having a frictional catching, which may be associated with an audible pop. At the knee, they may have an intra- or extra-articular origin. It is imperative to understand the etiology of the snapping to avoid unnecessary surgery.

Snapping symptoms affect the lateral aspect of […]

Current Trends Among US Surgeons in the Identification, Treatment, and Time of Repair for Medial Meniscal Ramp Lesions at the Time of ACL Surgery

2019 The Orthopaedic Journal of Sports Medicine

Meniscal ramp lesions are becoming increasingly recognized. Ramp lesions have been described as tears at the posterior meniscocapsular junction and/or tears of the posterior meniscotibial ligament, and they have a reported incidence of 16% to 40% of all anterior cruciate ligament (ACL) tears. Based on their location, these […]

Tibial Slope and Its Effect on Force in Anterior Cruciate Ligament Grafts

Background

Previous work has reported that increased tibial slope is directly correlated with increased anterior tibial translation, possibly predisposing patients to higher rates of anterior cruciate ligament (ACL) tears and causing higher rates of ACL graft fail- ures over the long term. However, the effect of changes in sagittal plane […]

Decreased Posterior Tibial Slope Does Not Affect Postoperative Posterior Knee Laxity After Double-Bundle Posterior Cruciate Ligament Reconstruction

Background

Recent clinical studies identified sagittal plane posterior tibial slope as a risk factor for increased postoperative lax- ity after single-bundle posterior cruciate ligament reconstruction (PCLR).

Purpose/Hypothesis

To retrospectively compare the degree of posterior tibial slope and its effect on posterior tibial translation (PTT) after double-bundle (DB) PCLR. Our null hypothesis was […]

So glad I waited for the best

I struggled with my knee for 18 months - having gone from 10,000 steps a day to only walking as needed. Previous attempts to make it better provided only temporary relief. (including injections and arthroscopic surgery), I heard Dr. La Prade was going to practice in the Twin Cities - where I live, & waited for him, based on his renown reputation. I am so glad I did! Dr LaPrade performed a deep root repair to my meniscus, which saved me from a knee replacement at this time. I am 5-months post surgery, and am doing great, stationary biking and exercising every day, no pain.
You know you are seeing the best when you find out he has written over 500 medical journal articles - among many other accomplishments. Hey - if he is good enough for Olympic and professional athletes…..he's good enough for me! Thank you, Dr. LaPrade, for treating me with the care, focus, and expertise as if I was an Olympic athlete!

Right Knee Surgery After Auto Bicycle Accident

Dr. Robert F. LaPrade operated on my right knee in May of 2010. I was hit by a car on my bicycle near Horsetooth Reservoir in CO. I was life flighted to MCR in Loveland, CO. My orthopedic injuries were severe, but totally missesd by the orthopedic team at Poudre. I could not bear weight on my right side though I tried repeatedly, but finally I went and got an MRI and one of the orthopedic surgeons that I worked with was shocked when he saw the MRI result. My right knee was totally destroyed; ACL, MCL, PCL all severely torn; the patella was the only thing intact in my right knee. Dr. La Prade had just moved to Vail and I was his 2nd patient @ The Steadman Clinic. I was told by one of the orthopedic surgeons that I worked with that I would never run again and would be lucky if I could ever hike again. This was devastating news after being a top triathlete (3rd in the world in my age group in 1989 & 1st nationally in my age group) and a big marathon runner. All I can say is Dr. La Prade did an amazing job and I am not limited in any of my activites. I can run, bike, & climb mountains. In fact 2 years ago I finished climbing the top 100 peaks in CO.

Very helpful

I have looked many times for answers on my tibial tubercle osteotomy and never found any as detailed as i needed. This answers all my questions!
