Association of Technology Usage and Decreased Revision TKA Rates for Low-Volume Surgeons Using an Optimal Prosthesis Combination: An Analysis of 53,264 Primary TKAs.

Background: Technology (navigation and robotics) usage during total knee arthroplasty (TKA) is often supported by literature involving high-volume surgeons and hospitals, but the value of technology for lower-volume surgeons is uncertain. This study aimed to determine if there was a relationship among surgeon volume, technology usage, and revision rate when using an optimal prosthesis combination (OPC).

Methods: Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) data were obtained from January 1, 2008, to December 31, 2022, for all primary TKA procedures performed for osteoarthritis using an OPC by a known surgeon ≥5 years after their first recorded procedure.

Fibrin clot augmentation of high-risk meniscal repairs may result in clinical healing in up to 90% of cases.

Objective: While meniscal repair is preferable to meniscectomy, some cases may be at higher risk of failure if repaired. Incorporating fibrin clot (FC) into the repair has been proposed to improve healing rates. The purpose of this study was to determine the failure rates, patient reported outcome measures (PROMs) and complications of FC augmented meniscal repair for cases considered to be at higher risk of failure.

Severe mucoid degeneration of the anterior cruciate ligament (ACL) treated with conservative arthroscopic debridement and platelet-rich plasma (PRP) injection.

Mucoid degeneration of the anterior cruciate ligament (ACL) can be treated with arthroscopic debridement, however, instability can ensue. Here, we present a fit and active woman in her 60s with severe mucoid degeneration of the ACL who underwent conservative arthroscopic debridement and treatment with intraligamentous administration of platelet-rich plasma (PRP). After 1 month, the patient demonstrated significant improvements in range of motion and pain symptoms, with nil resultant laxity.

Meniscal allograft transplantation: undersizing grafts can lead to increased rates of clinical and mechanical failure.

Purpose: To assess mid-term survivorship of meniscal allograft transplantation (MAT) and determine the effect that pre-operative meniscal sizing has upon functional outcome and mechanical survivorship.

Methods: A prospectively collected database of patients receiving MAT from 2001 to 2017 was analysed. Data include demographics; sizing measurements, complications, further surgery, and patient-reported outcome measures (PROMs).

Correction to: A case series of lateral opening wedge high tibial osteotomy for valgus malalignment.

Unfortunately, one of the co-author affiliation was incorrect in the original publication of this article. The correct affiliation is given below: Abdulaziz Z. Alomar, King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Saudi Arabia.

A case series of lateral opening wedge high tibial osteotomy for valgus malalignment.

Introduction: Lateral opening wedge high tibial osteotomy is a rarely employed surgical technique used for the treatment of lateral knee pain and degeneration in the setting of genu valgum. There exists little evidence of the suitability of this procedure for patients requiring osteotomies with a small correction.

Materials And Methods: A case series of 23 patients (24 knees) undergoing lateral opening wedge high tibial osteotomy with a minimum follow-up of 2 years was performed between 2002 and 2008.

Meniscal repair in the elite athlete: results of 45 repairs with a minimum 5-year follow-up.

Background: The preservation of meniscal tissue is important to protect joint surfaces.

Purpose: We have an aggressive approach to meniscal repair, including repairing tears other than those classically suited to repair. Here we present the medium- to long-term outcome of meniscal repair (inside-out) in elite athletes.

Bioabsorbable versus titanium interference screws with hamstring autograft in anterior cruciate ligament reconstruction: a prospective randomized trial with 2-year follow-up.

Purpose: The purpose of this study was to prospectively assess the outcome of hamstring autograft anterior cruciate ligament (ACL) reconstruction by use of identically shaped bioabsorbable and titanium interference screws in a randomized trial.

Methods: One hundred patients were randomized to have either bioabsorbable or titanium interference screws used for graft tunnel fixation in hamstring autograft ACL reconstruction. Patients were objectively and subjectively assessed preoperatively and 3, 6, 12, and 24 months postoperatively.

Central versus peripheral tibial screw placement in hamstring anterior cruciate ligament reconstruction: in vitro biomechanics.

Purpose: To determine whether a cone-shaped interference screw positioned centrally during tibial fixation in hamstring anterior cruciate ligament (ACL) reconstruction was equal to or better than a peripheral position in terms of stiffness, yield load, ultimate load, and mode of failure.

Type Of Study: Randomized matched-pair biomechanical pullout study.

Methods: One of each of 7 matched pairs of human cadaveric tendon in porcine tibia with titanium cone-shaped screws were randomly allocated to either the peripheral or central group.

Meniscus preservation; rationale, repair techniques and results.

It is inescapable that loss of part or all of the structure of the meniscus of the knee alters the biomechanics of knee function leading to a gradual deterioration of the chondral surface, which ultimately will result in osteoarthritis. The goal of the knee surgeon should therefore be to preserve as much as possible the function of the meniscus. Classic teaching is that many meniscal tears, which are peripheral and longtitudinal, will heal if sutured and protected during a slow healing process.

The three-in-one proximal and distal soft tissue patellar realignment procedure. Results, and its place in the management of patellofemoral instability.

The three-in-one procedure for extensor mechanism realignment of the knee combines lateral release, vastus medialis obliquus muscle advancement, and transfer of the medial one-third of the patellar tendon to the tibial collateral ligament. We observed 37 patients (42 knees) receiving this treatment at a minimum 25-month follow-up (range, 25 to 85 months; mean, 44). Thirty-two of 42 knees (76%) with recurrent patellar dislocation had good or excellent results after surgery.

Broken arrow: a complication of meniscal repair.

A case is reported in which a biodegradable arrow, used for arthroscopic meniscal repair, broke and migrated from the back to the front of the knee. Further surgery was necessary to remove the broken fragment. The concept of this sort of repair device is appealing as it may overcome some of the difficulties of suture repair techniques for posterior meniscal tears.

Localized pigmented villonodular synovitis: a rare cause of locking of the knee.

A 34-year-old woman presented with a history of recurrent episodes of knee locking and swelling. Arthroscopy revealed characteristic brown colored pedunculated lesions in the intercondylar notch region. These were clearly causing interference to joint motion.
