Item The 360 degrees Performance System in Team Sports: Is It Time to Design a ``Personalized Jacket'' for Team Sports Players?(MDPI, 2021-01-01) Jukic, Igor; Calleja-Gonzalez, Julio; Cuzzolin, Francesco; Sampaio, Jaime; Cos, Francesc; Milanovic, Luka; Krakan, Ivan; Ostojic, Sergej; Olmo, Jesus; Requena, Bernardo; Njaradi, Nenad; Sassi, Roberto; Rovira, Mar; Kocaoglu, BarisElite performance in team sports attracts the attention of the general public. In particular, the best players became incredibly skilled and physically powerful, which is a fact that potentiates the delivery of a product that is considered attractive, exciting, and competitive. Not surprisingly, this is a very valuable product from an economic and social standpointItem Femoral and Tibial Bony Risk Factors for Anterior Cruciate Ligament Injuries Are Present in More Than 50\% of Healthy Individuals(SAGE PUBLICATIONS INC, 2021-01-01) Micicoi, Gregoire; Jacquet, Chistophe; Khakha, Raghbir; LiArno, Sally; Faizan, Ahmad; Seil, Romain; Kocaoglu, Baris; Cerciello, Simone; Martz, Pierre; Ollivier, MatthieuBackground: Anterior cruciate ligament (ACL) injuries are multifactorial events that may be influenced by morphometric parameters. Associations between primary ACL injuries or graft ruptures and both femoral and tibial bony risk factors have been well described in the literature. Purpose: To determine values of femoral and tibial bony morphology that have been associated with ACL injuries in a reference population. Further, to define interindividual variations according to participant demographics and to identify the proportion of participants presenting at least 1 morphological ACL injury risk factor. Study Design: Cross-sectional studyItem Arthroscopic Repair of the Hip Abductor Musculotendinous Unit: The Effect of Microfracture on Clinical Outcomes(SAGE PUBLICATIONS INC, 2021-01-01) Kocaoglu, Baris; Paksoy, Ahmet Emre; Cerciello, Simone; Ollivier, Matthieu; Seil, Romain; Safran, MarcBackground: Endoscopic surgical repair has become a common procedure for treating patients with hip abductor tendon tears. Considering that retear rates are high after the repair of gluteus medius and minimus tendons, exploring alternative strategies to enhance structural healing is important. Purpose/Hypothesis: The purpose of this study was to evaluate the effect of adding microfracture to single-row repair (SR) on outcomes after the surgical repair of gluteus medius and minimus tendons and compare with SR and double-row repair (DR) without microfracture. We hypothesized that microfracture of the trochanteric footprint with SR would lead to superior clinical outcomes and lower clinically evident retear rates compared with SR and DR without the addition of microfracture. Study Design: Cohort studyItem The effect of platelet-rich plasma in bone-tendon integration(WROCLAW MEDICAL UNIV, 2017-01-01) Agir, Ismail; Aytekin, Mahmut Nedim; Kucukdurmaz, Fatih; Kocaoglu, Baris; Cetinel, Sule; Karahan, MustafaBackground. The operative reconstruction of a torn or insufficient anterior cruciate ligament has become a routine surgical procedure in orthopedics. The long-term success of an anterior cruciate ligament reconstruction depends on the ability of the graft to heal adequately in a bone tunnel. Investigators studying reconstructions described healing within a tunnel as osseous ingrowth and incorporation. In particular, helping the healing using autologous material for the best integration process was a new idea that helped us to set up this study. Objectives. The purpose of this study is to show the effect of platelet-rich plasma on bone-tendon healing. Material and methods. Ten New Zealand rabbits were used. The study had 2 groups: (1) a study group including the right extremities of rabbits in which tendon-bone integration was strengthened by platelet-rich plasma and (2) a control group including the left extremities of rabbits in which tendon-bone integration was without platelet-rich plasma. On the 56th day postoperatively, the portion of the distal femur containing the tunnel was amputated following the euthanization process for histological evaluation. Results. In the histological evaluation of the tendon-integrated bone segments with platelet-rich plasma, the integration of tendon in the bone was successful without any necrosis formation in most of the tissues. However, in the control group without platelet-rich plasma, the integration was distorted in many zones and some cystic morphologies were present. Conclusions. The findings of this study showed that using platelet-rich plasma during tendon-to-bone implantation has positive effects histologically. In the literature, many studies are available that have investigated the effect of platelet-rich plasma on anterior cruciate surgery radiologically. However, the histological findings are more reliable than radiological findings because bone-tendon integration is a biological process.Item Perpendicular drill bit alignment provides a practical guidance to determine the appropriate suture anchor insertion angle during acetabular labral repair(OXFORD UNIV PRESS, 2022-01-01) Ismailoglu, Abdul Veli; Ozdogmus, Omer; Karaman, Muhammed Ilkay; Kayaalp, Asim; Kocaoglu, BarisThe safe acetabular rim angle is an anatomical measurement used to determine the safety margin when inserting suture anchors. The purpose of the present study was to find out whether aligning the drill bit perpendicularly during arthroscopic surgery can provide a reference point for determining an appropriate angle to facilitate the suture anchor insertion and to prevent extra- and intra-articular perforations. One hundred computed tomographic hips were used to reconstruct three-dimensional acetabular hip models. Each model was radially sectioned at the 4 o'clock, 3 o'clock and anterior inferior iliac spine (AIIS) positions (that corresponded mainly to the 2:20 clock position). A perpendicular reference line, representing a perpendicular drill bit alignment, was drawn for each position within the acetabular model, and its relation to the safe acetabular rim angle was measured. The length of the perpendicular reference line and the effect of gender on measurements were also evaluated. The mean safe acetabular rim angle at the 3 o'clock position was significantly smaller compared to other clock positions (P < 0.001). The perpendicular reference line was located out of the safe acetabular rim angle in 28 cases (\%28), mostly in female acetabula at the 3 o'clock position, and relative to the perpendicular reference line the required minimal angle was 4 degrees +/- 2.3 degrees to place the anchor in the safe acetabular rim angle to avoid extra-articular perforation. The perpendicular reference line was shortest at the 3 o'clock position, and its mean length was shorter in female acetabula at all clock positions (P < 0.001). Aligning the drill bit perpendicular to the acetabular opening plane during an arthroscopic anchor placement is a practical way to estimate and target the position of the safe acetabular rim angle to avoid anchor perforations. Based on measurements from a perpendicularly aligned drill bit, the drill bit should be directed towards the joint minimally by 4 degrees to avoid extra-articular perforations and maximally by 30 degrees to avoid intra-articular perforations.Item Warm irrigation fluid does not raise the subacromial temperature to harmful levels while using radiofrequency device(MEDKNOW PUBLICATIONS \& MEDIA PVT LTD, 2015-01-01) Gereli, Arel; Kocaoglu, Baris; Guven, Osman; Turkmen, MetinItem Comparison of headless screws used in the treatment of proximal nonunion of scaphoid bone(SPRINGER, 2011-01-01) Gereli, Arel; Nalbantoglu, Ufuk; Sener, Ismail Ugur; Kocaoglu, Baris; Turkmen, MetinScrews with different levels of compression force are available for scaphoid fixation and it is known that the Acutrak screw generates greater compression than the Herbert screw. We retrospectively compared two types of headless compression screw for their effectiveness in the repair of scaphoid nonunion. Twenty-nine cases of proximal scaphoid nonunion were surgically treated with non-vascularised bone graft: the Acutrak screw was used in 17 patients and the cannulated Herbert screw in 12 patients. Wrist range of motion, Mayo wrist score, grip strength and QuickDASH scores were indicators used for the functional evaluation. Radiographic findings were assessed for consolidation of nonunion and signs of arthrosis. The mean follow-up time was 49.2 months (range 12-96). Statistically, there was no significant difference between the Acutrak and Herbert screw types in terms of functional evaluation and time required for consolidation. Greater compression did not influence the functional outcome, consolidation rate or time to consolidation. The need for greater compression in the treatment of proximal scaphoid nonunions is thus questionable because it may increase the risk of proximal fragment communition.Item Partial Rotator Cuff Repair With Superior Capsular Reconstruction Using the Biceps Tendon Is as Effective as Superior Capsular Reconstruction Using a Tensor Fasciae Latae Autograft in the Treatment of Irreparable Massive Rotator Cuff Tears(SAGE PUBLICATIONS INC, 2020-01-01) Kocaoglu, Baris; Firatli, Goktug; Ulku, Tekin KeremBackground: Several treatment options are available for stable massive rotator cuff tears, including partial repair with or without tissue augmentation, tendon transfer, superior capsular reconstruction (SCR), and reverse shoulder arthroplasty. Purpose/Hypothesis: The purpose of this study was to compare the outcomes and effectiveness of partial rotator cuff repair with SCR using the long head of the biceps tendon (PRCR-SCRB) and SCR with a tensor fasciae latae autograft (SCRTF) for the treatment of rotator cuff tears with severe fatty degeneration. The hypothesis of this study was that SCRTF would be superior to PRCR-SCRB in functional and anatomic outcomes.
