C-reactive Protein Levels After Anterior Cruciate Ligament Reconstruction.

Introduction Understanding standard changes in C-reactive protein (CRP) after Anterior cruciate ligament reconstruction (ACLR) is important for early detection of septic arthritis. Methods We conducted a prospective two-center comparative study to clarify changes in postoperative CRP levels after ACLR, as well as factors that influence the changes, in a large sample of Asian patients. A total of 439 ACLR cases were included in this study.

Significantly smaller lateral extrusion was observed within 24 weeks after all-inside suture repairs of radial tear in the middle segment of lateral meniscus compared to inside-out repairs.

Purpose: To evaluate the postoperative meniscal extrusion between all-inside suture (AIS) and trans-capsular suture (TCS) repair techniques.

Methods: Thirteen patients (mean age, 19.4 years) underwent AIS repairs using only sutures (AIS group) for radial tears in the middle segment of the lateral meniscus (RTMLM), and seven patients (mean age, 20.

All-inside suture meniscal repair using suture passer.

In recent years, to save the meniscus and prevent the progression of knee osteoarthritis, the indications for meniscus repair have been expanding instead of partial menisectomy. Accordingly, various repair techniques for meniscus tears have been developed. The conventional inside-out and outside-in meniscus repair techniques and all-inside repair technique with an implant/anchor can be classified as trans-capsular (TC) repair from the perspective of suture with penetrating capsule.

Association of Stability and Size of Unhealed Area With Failure After Internal Fixation for Osteochondritis Dissecans Lesions of the Knee: Radiological Evaluation Using Computed Tomography.

Background: Open reduction and internal fixation (ORIF) has been widely performed because the osteochondral component of the osteochondritis dissecans (OCD) lesion is the most suitable for reconstructing the joint structure.

Purpose: To evaluate radiological healing in terms of reconstructed bony structure after ORIF with bone graft by computed tomography (CT), to identify preoperative prognostic factors for failure, and to determine the cutoff value of radiological healing for risk of failure.

Study Design: Case-control study; Level of evidence, 3.

Single-Leg Loading Test to Predict Time to Jog and Return to Sports after Acute Lateral Ankle Sprain in Competitive Athletes.

In a previous study, the utility of a single-leg loading (SLL) test after acute lateral ankle sprain (LAS) was reported. However, whether the severity level assessed by the SLL test is associated with the time to jog and return to sports (RTS) remains unclear. Therefore, this study aimed to examine whether the time to jog and RTS differ depending on the severity level.

Clinical outcomes after repair of an isolated radial tear in the middle segment of the lateral meniscus - All-inside suture repair vs trans-capsular suture repair.

Background/objective: For radial tears, all-inside suture (AIS) repair was clearly biomechanically superior, compared to conventional trans-capsular suture (TCS) repairs. However, clinical comparative studies of these two repairs techniques have not to be performed. Therefore, the aim of this study was to compare the clinical outcomes after AIS repair and TCS repairs for isolated radial tear at middle segment of lateral meniscus (RTMLM) in stable knees of young athletes.

The Wound Dressing Influenced Effectiveness of Cryotherapy After Anterior Cruciate Ligament Reconstruction: Case-Control Study Comparing Gauze Versus Film Dressing.

Purpose: To compare the clinical effectiveness of cryotherapy after anterior cruciate ligament reconstruction using 2 different wound dressings, conventional postoperative gauze dressings and polyurethane semipermeable transparent film dressings.

Methods: In total, 60 patients who had undergone arthroscopic anterior cruciate ligament reconstruction with an autogenous patellar tendon were assigned to 2 groups. The surgical wound was covered with 5 sheets of gauze with an elastic bandage (control group) in 30 patients and film dressing was used (film group) in the remaining 30 patients.

Rectangular bone-patellar tendon bone grafts reduce early graft failure in chronic ACL-Deficient knees.

Background: The aim of this study was to assess early graft failure after anterior cruciate ligament (ACL) reconstruction according to chronicity of ACL deficiency (ACLD) and clarify predisposing factors.

Methods: A total of 731 patients who underwent anatomic ACL reconstruction were divided into 3 groups based on chronicity of ACLD: <6 months (Group 1), 6 months to 2 years (Group 2), and >2 years (Group 3). Types of ACL grafts used included single-bundle hamstring tendon (HT), multiple-bundle HT, and rectangular bone-patellar tendon-bone (BTB) grafts.

Changes in patellar height after anatomical ACL reconstruction with BTB autograft with a focus on patellar tendon removal volume.

Background: Although anatomical anterior cruciate ligament reconstruction (ACLR) can provide satisfactory outcomes, little is known about how this procedure impacts patellar height. Since harvesting bone-patellar tendon-bone (BTB) autografts is a potential risk factor for decreased patellar height, we examined changes in patellar height after anatomical ACLR with BTB autograft with a focus on the size of the harvested graft.

Methods: Subjects were 84 patients (49 males, 35 females; mean age, 23 years) who underwent primary anatomical ACLR with central third BTB autograft.

Isolated peripheral longitudinal tears in the anterior-middle segment of medial meniscus among young soccer players: A case series.

Introduction: There was little information about the isolated medial meniscal tears in the anterior-middle segment. This study aimed to report the infrequent cases of the isolated medial meniscal tears in the anterior-middle segment related to kicking motion among young soccer players with a short-term postoperative outcome.

Presentation Of Case: In the retrospective review of the surgical records from 2000 to 2018, there were 15 cases with the corresponding tear.

Posterior Ankle Impingement Caused by Hyaline-Like Cartilage Generation in Ballet Dancers-A Report of 2 Cases.

Posterior ankle impingement syndrome is mainly seen in ballet dancers and frequently associated with specific movements in ballet such as pointe and demi pointe in which the whole-body weight is applied to the maximally plantar flexed ankle. We performed arthroscopic debridement for 2 dedicated ballet dancers on the intervening soft tissue causing posterior ankle impingement syndrome (PAIS). In both cases, T2-weighted magnetic resonance imaging (MRI) revealed low-signal intensity of meniscus-like soft tissue without abnormal osseous findings, connecting from the posterior side of the talus to Kager's fat pad.

Second-look arthroscopy after double-bundle posterior cruciate ligament reconstruction: Effect of patient age.

Purpose: Second-look arthroscopy is invasive but still one of the most useful postoperative evaluation methods since graft morphology including graft tension, graft tear, and synovial coverage can be directly evaluated. However, only a few studies have evaluated transplanted posterior cruciate ligament (PCL) grafts. This study aimed to clarify the PCL graft morphology and chondral damages at second-look arthroscopy after double-bundle PCL reconstruction (PCLR) and to investigate the effects of patient age on these arthroscopic findings.

Sequential Changes in Posterior Tibial Translation After Posterior Cruciate Ligament Reconstruction: Risk Factors for Residual Posterior Sagging.

Background: Residual posterior sagging may occur after posterior cruciate ligament (PCL) reconstruction (PCLR), yet when it mainly occurs is not fully understood.

Purpose: To elucidate sequential changes in radiographic posterior tibial translation (PTT) after PCLR.

Study Design: Case-control study; Level of evidence, 3.

Quick and simple test to evaluate severity of acute lateral ankle sprain.

Background/objective: For early return to sports after a lateral ankle sprain (LAS) and recurrence prevention, effective rehabilitation and gradual return to sports should be initiated while predicting the return time based on the appropriate severity evaluation immediately after injury. However, since severity evaluations performed in previous studies required large space and stairs and involved high-revel activity, their use as a test and index to evaluate severity after LAS was not appropriate considering convenience and risk of re-injury. Therefore, a quick and simple test was developed to evaluate the severity of acute LAS.

Tunnel Enlargement Correlates With Postoperative Posterior Laxity After Double-Bundle Posterior Cruciate Ligament Reconstruction.

Background: There exists little information in the relevant literature regarding tunnel enlargement after posterior cruciate ligament (PCL) reconstruction (PCLR).

Purpose: To sequentially evaluate tunnel enlargement and radiographic posterior laxity through double-bundle PCLR using autologous hamstring tendon grafts.

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

Preoperative quadriceps strength as a predictor of return to sports after anterior cruciate ligament reconstruction in competitive athletes.

Objectives: To determine whether preoperative quadriceps strength predicts the likelihood of return to sports (RTS) following anterior cruciate ligament reconstruction (ACLR) in competitive athletes.

Design: Case-control study.

Setting: Single-center.

Biological Augmentation of ACL Repair and Reconstruction: Current Status and Future Perspective.

Historically, anterior cruciate ligament (ACL) suture repair mostly resulted in failure because of intra-articular hypovascularity and poor intrinsic healing capacity of ACL. ACL reconstruction was therefore deemed the gold standard with a high success rate because of more evolved surgical technique. There are, however, clinical and subclinical disadvantages of reconstruction; low rate in full recovery to sports, donor harvest morbidity, tunnel enlargement, and incomplete microscopic healing of the graft.

All-Inside Suture Repair for Isolated Radial Tears at the Midbody of the Lateral Meniscus.

In young athletes, radial tear of the midbody on the semilunar lateral meniscus in stable knees is most common. Conventionally, for this type of tear, meniscectomy has been considered as a first-line treatment. However, meniscectomy does not prevent degenerative change.

Importance of functional performance and psychological readiness for return to preinjury level of sports 1 year after ACL reconstruction in competitive athletes.

Purpose: This study aimed to identify independent predictive factors for return to sports (RTS) after anterior cruciate ligament (ACL) reconstruction in competitive-level athletes and to determine optimal cut-off values for these factors at 6 months after surgery.

Methods: A total of 124 competitive athletes (50 males and 74 females; mean age, 17.0 years; preinjury Tegner activity scale > 7) who underwent primary ACL reconstruction were enrolled.

Autologous Osteochondral Transplantation in Full-thickness Patella Chondral Lesion: A Case Series.

Purpose: Autologous osteochondral transplantation (AOT) in the focal cartilage lesion of the patella has been reported with less successful results compared with other sites. The purposes were to investigate the clinical outcomes of AOT for focal patellar chondral lesion without patellofemoral instability.

Methods: Between 2001 and 2007, six patients (five males and one female) with a focal patellar cartilage lesion without patellofemoral malalignment and instability were treated with AOT.

Discoid lateral meniscal repair without saucerization for adolescents with peripheral longitudinal tear.

Recently, successful clinical outcomes for symptomatic discoid lateral meniscus (DLM) have been reported following partial meniscectomy (saucerization) with repair. In contrast, some studies using radiography and magnetic resonance imaging (MRI) have suggested that function of load transmission might not be appropriately maintained after saucerization with repair. Therefore, in pursuit to uphold load transmission after surgery for DLM, this study tried to preserve the DLM shape to keep the original DLM function.

Positive Effects of Yoga on Physical and Respiratory Functions in Healthy Inactive Middle-Aged People.

Context: Yoga improves physical and respiratory functions in healthy inactive middle-aged people.

Aim: This study aimed to assess the effects of 8 weeks of and with lessons in order to clarify the influence of two different combinations of yoga practice on physical and respiratory functions in healthy inactive middle-aged people.

Subjects And Methods: A total of 28 participants (mean age: 52.

Relationship between bone plug position and morphological changes of tunnel aperture in anatomic rectangular tunnel ACL reconstruction.

Purpose: In animal studies after ACL reconstruction (ACL-R) using the bone-patellar tendon-bone (BTB), the graft-healing pattern was found to depend on the relationship between bone plug and the tunnel wall. This difference of graft-healing pattern could influence the postoperative morphological changes of the tunnel. However, no study has assessed the relationship between bone plug position and the change of tunnel morphology.

Osteochondritis Dissecans of the Knee: Short-Term Outcomes of a Hybrid Technique to Restore a Partially Salvageable Progeny Fragment.

Objective: This retrospective case series describes a hybrid fixation technique and determines the clinical outcomes, knee function, and activity level of patients at short-term follow-up.

Design: Seventeen patients (18 knees) with unstable osteochondritis dissecans (OCD) lesions involving the knee were treated with a hybrid fixation technique in which the salvageable fragment was fixed and osteochondral autograft transplantation system (OATS) was used for the unsalvageable fragment. Thirteen lesions involved the medial femoral condyle, 4 involved the lateral femoral condyle, and 1 involved the patella.
