Background

High tibial osteotomy is a common procedure to treat symptomatic osteoarthritis of the medial compartment of the knee with varus alignment. This is achieved by overcorrecting the varus alignment to 2–6° of valgus. Various high tibial osteotomy techniques are currently used to this end. Common procedures are medial opening wedge and lateral closing wedge tibial osteotomies. The lateral closing wedge technique is a primary stable correction with a high rate of consolidation, but has the disadvantage of bone loss and change in tibial condylar offset. The medial opening wedge technique does not result in any bone loss but needs to be fixated with a plate and may cause tibial slope and medial collateral ligament tightening.

Purpose

The purpose of this article is to examine correlation between femoral rotational angle and subjective satisfaction of high tibial osteotomy outcome of the range of motion of knee joint.

The acetabular labrum serves many integral functions within the hip joint. As a result, novel surgical techniques that aim to preserve or reconstruct the labrum have entered the spotlight. We have successfully performed a labral reconstruction using the quadriceps tendon as an autograft for a patient with a moderate labral defect. The purpose of this report is to propose this novel donor site as a viable alternative for labral reconstruction using an autograft; the potential benefits over currently popular methods will be discussed.

Background

Recent studies reported that the kinematic alignment of an implant is more physiological than the traditional methods, and therefore results in better clinical outcomes. They found that for kinematic alignment of the implant, the femoral component should be positioned valgus 2 degrees and tibial component in varus 2 degrees without femoral rotation. Other study also claimed that kinematically aligned TKA does not cause any significant failure; rather, it restores the function of the knee. Therefore kinematic alignment was raised for further patient's functional satisfaction.

Purpose

The purpose of our study is to certify correlation between parameters of implant position and postoperative clinical outcomes after kinematic alignment of TKA.

Background

It is still controversial whether “labral tear” in the pelvis or “pincer type's femoroacetabular impingement syndrome” should be considered a pathologic lesion, and whether they cause the early onset of osteoarthritis in the pelvis.

Hypothesis

The disruption of chondrolabral junction causes degenerative change on hip joint, and the disruption of the vessel tissue to the labrum induces the rapidly progressive degeneration of outside in osteoarthritis changes.

The first case was that of an 89-year-old woman with advanced dementia. After falling onto the left hip, she was admitted to the emergency room. Standard x-rays revealed an unstable intertrochanteric fracture. Closed reduction and internal fixation was performed using the long PFNA with a 105-mm helical blade, the second patient treated with this implant in our series. The operation was performed by an attending surgeon who was experienced with treatment of trochanteric fractures with intramedullary devices. Six weeks later the patient presented again with severe pain after she had fallen onto her left hip for a second time. Follow-up x-rays showed a perforation of the helical blade through the cortex of the femoral head after a shortening of the femoral neck by 2 cm. CCD angle was still 129 degrees, and there were no radiological signs of rotational displacement. The acetabular cartilage appeared intact. At her second operation, a replacement of the blade was performed using a shorter 95-mm implant. Postoperatively the patient was again mobilized under full weight bearing, and at 12 weeks follow-up, we found cut through again, we replaced hip with biopolar hemiarthroplasty.

Introduction

Patient demand for a less invasive surgical approach reducing the trauma induced to the joint has resulted in the development of Minimally Invasive Surgery (MIS). Although the length of the surgical incision is appealing to patients, the changes are not purely cosmetic. The surgery should not violate the extensor mechanism in any way. Incisions into the quadriceps tendon or into the vastus medialis muscle make the approach less difficult but this violation will slow the recovery and affect the ROM of the knee. In Asian knees, authors found the variation of VMO, which is essential in early functional recovery in TKA patient, is so much, so new clinical test for MIS QS should be needed to show location relationship between the upper pole of the patella and the insertion of VMO itself to avoid unnecessary injury of VMO during TKA.

Purpose

The purpose of this comparison study was to verify whether MIS QS TKA can be a more functional and better method in treatment of advanced degenerative arthritis comparing with mini MIS TKA.

Introduction

Recently robotic-assisted total knee replacement has become a new emerging method of artificial joint implantation, especially in Europe and Asia. We have belived that robotic cutting would result in an improved clinical outcome due to the better fit and alignment of the prosthesis but that has never been proven to our knowledge. The purpose of this study was to compare robotic-assisted implantation of a total knee replacement with conventional manual implantation.

Methods

We reviewed 72 patients who were scheduled for total knee arthroplasty, divided to have either conventional manual implantation of a Zimmer LPS prosthesis (30 patients: Group I) or robotic-assisted implantation of such a prosthesis (32 patients: Group II). The five-axis ROBODOC was used for the robotic-assisted procedures. Radiographs were made at this interval and analyzed for evidence of loosening, prosthetic alignment, and other complications. Independent T-test or Mann-Whitney test was used for statistical analysis at probability level of 95%. SPSS for Windows was used.
