Background: This study aimed to assess the arthroscopic treatment, one of the surgical treatment options, for early grade focal osteochondral lesions of the first MTP joint, and to determine the impact of the arthroscopic microdrill hole surgery on foot function and daily life in a patient group with failed conservative treatment. Materials-Methods: This prospective study reviewed 27 patients having hallux rigidus with osteochondral injury of the first MTP joint who were operated with first MTP joint arthroscopy. Six patients had Coughlin-Shurnas grade 4 hallux rigidus and were excluded from the study; 5 patients were excluded due to having an arthroscopic kissing lesion, and 3 patients were excluded for not having attended regular follow-up after third month. After excluding the above patients, the study was completed with 14 patients Results: The mean hallux vagus angle was 13.29⁰ (±1.93 SD) and the mean intermetatarsal angle was 9.14⁰ (±0.86 SD). Apart from joint arthroscopy, no soft tissue procedure and/or any procedure requiring osteotomy was intended in any patient. The median operative duration was 27.8 (19-56) minutes.The patients had mean preoperative VPS and AOFAS-Hallux scores of 8.14±0.86 SD and 48.64±4.27, respectively; the corresponding postoperative values of both scores were 1.86±0.66 SD and 87.00±3.70. Both VPS and AOFAS-Hallux scores changed significantly (p<0.01) Discussion: In this prospective study we explored the impact of arthroscopic microdrill hole surgery on foot functions and daily life activities in patients with focal osteochondral lesions of the first MTP joint. Our results indicated significant improvements in VAS and AOFAS scores with this treatment. The micro drill technique we applied in this study is based on the principle of opening 4-6-mm long tunnels to enable stem cells to migrate to the defected area and achieve cure by differentiation in full-thickness chondral injuries with exposed subchondral bone.In conclusion, arthroscopic microhole drill technique can be applied with impressive functional scores and without any complication in persons who failed conservative therapy for hallux rigidus with focal chordal injury, a common foot problem. There is a need for comparative studies with long follow-up period in this field.

Aim: The purpose of this study is to determine the relationship between isokinetic wrist muscle strenght and grip strength in tennis players aged between 12-14. Methods: This study was carried out with the participation of 9 (3 female and 6 male) tennis players aged between 12-14 (means 13,22±0,83). Weight, height, body mass index and dominant extremity of the players were recorded. İsokinetic measurement was performed with Isomed 2000® device. İsokinetic testing protocol; before the test all players performed the wrist flexion and extension isokinetic test with the 5 repeating at 90 º/sec as a warm-up and for comprehenting the test. Then, wrist flexion and extension concentric-concentric strength measurements were performed with the 5 repeating at 60 º/sec and with the 15 repeating at 240 º/sec with the angle between 50 degrees of wrist flexion and 60 degrees of wrist extension and peak torque values were recorded. Standard Jamar® Dynamometer was used for grip strength measurements. Grip strenght was performed firstly in sitting position, which is the position of standard measurement. Secondly, in standing position, the elbow was in full ekstansion and the forearm was in neutral position. Thirdly, in standing position the wrist was positioned approximately 30° extension and 10° ulnar deviation. This test was repeated 3 times in all test position and the mean of three scores were recorded. Firstly, the dominant hand, then the non-dominant hand was evoluated. They were allowed to rest for 30 seconds between each grip measurement. Correlation between peak tork of isokinetic muscle strenght and grip strength was done having been used Spearman correlation test. Findings: It was determined that there was a significant positive relation between wrist flexion-extension isokinetic muscle strength and grip strenght in tennis players aged between 12-14. Clinically, grip strength measured in the standard sitting position was found more as compared to the other positions but these values were not statistically significant (p>0,05). Accordingly, grip strength measured in the standard sitting position correlated with much more of the parameters which we evaluated for isokinetic muscle strength comparing to grip strenght measured in the other two positions (p<0,05). Results: It was concluded that isokinetic muscle strength of wrist can be affected by grip strength, therefore measurement needs to be done in the sitting position which maximum grip strength may reveal.

Objective: The aim of the study was to investigate the effects of shoulder and scapular region rigid taping and kinesio taping on scapular dyskinesis and pectoralis minor shortness in overhead athletes. Method: This study included 72 overhead athletes. The athletes were randomly divided into four groups: kinesio taping (shoulder and scapular region) was applied to Kinesio Taping Group (KB), rigid taping (shoulder and scapular region) was applied to Rigid Taping Group (RB), placebo kinesio taping was applied to Placebo Taping Group (PB). Control group received no tape. Demographic data of overhead athletes, anthropometric characteristics, pain severity and injury background were evaluated before taping. Pectoralis minor shortness (Pectoralis Minor Index) and scapular dyskinesis (Scapular Dyskinesis Test) were evaluated before taping, immediately after (30-minutes) taping and after 48 hours of use within 12-24 hours. Control group was evaluated at the same periods. Results: Before taping; demographic, anthropometric and sports-related characteristics were similar in groups and there was no statistically difference (p>0.05). It was determined that Pectoralis Minor Index (PMI) and scapular dyskinesis improved immediately after taping and after 48 hours of use in KB and RB (p<0.05). There were no significant differences after taping for PMI among groups (p>0.05). Conclusion: Kinesio taping and rigid taping seems to have positive effects on scapular dyskinesis and pectoralis minor shortness in overhead athletes. Future studies on larger sample size are needed to verify the differences of the effects of these taping techniques between placebo or controls.

Aim: In addition to exercise, physical and electrotherapy modalities such as hotpack, ultrasound and TENS is often applied on frozen shoulder rehabilitation in clinics. The aim of this study was to compare the effectiveness of electrotherapy modalities versus home exercises program in addition to standard physical therapy in both groups on frozen shoulder rehabilitation. Methods: 24 patients diagnosed with frozen shoulder were included in this study. Patients were randomly assigned to Group I (Standard program + electrotherapy, n = 12) and Group II (standard program + home exercise program, n = 12). Standard program consisted of shoulder joint mobilization and shoulder muscles.stretching and strengthening exercises (30 minutes). In addition to this program, Group 1 received Hotpack, ultrasound and TENS for 30 minutes. Group II was given a 30-minute home program including Wand exercises, isometric strengthening and self stretching exercises in addition to standart program. Treatment was applied five day a week for 3 weeks. Patients level of pain, functional state, level of depression and sleep quality evaluated before and after treatment by the Visual Analogue Scale (VAS), the Disabilities of the Arm, Shoulder and Hand (DASH), the Beck Depression Inventory (BDI) and the Pittsburgh Sleep Quality Index (PSQI) respectively. The data were analyzed using the SPSS 20.0 software. The intra-group variations were analyzed using Wilcoxon’s signed-rank test, while inter-group comparisons were drawn using the Mann-Whitney U-test. Result: Study was completed total 22 patients (mean age: 55.2 ± 10.4 years; BMI = 27.7 ± 3.9 kg / m2, 15 women) Group I (n = 12) and Group II (n = 10). VAS-resting (p = 0.011; p = 0.015), VAS-activity (p = 0.005; p = 0.002), BDI (p = 0.012; p = 0.004) and the DASH (p = 0.005 and p = 0004) found a statistically significant improvement in both intra-group change. VAS-night (p = 0.039) and sleep quality (p = 0.047) was found a significant improvement only in Group I. But there was no statistically significant difference between the groups in any parameter (p> 0.05). Conclusion: However VAS-night and sleep quality improved in electrotherapy in terms of intra group change, there was no significant difference between the groups in any parameter. Therefore, we believe that the choice of home exercise program applied in addition to the exercise programwould be more advantageous in terms of cost-effectiveness and time instead of electrotherapy modalities.

Objective: The purpose of this study was to identify relationships between endurance of periscapular muscle, anaerobic performance and agility in professional athletes. Methods: 70 professional basketball, volleyball, and handball players (male: 25 female: 45 age 20.41±5.72, BMI: 21.70±2.51) were included to this study. Anaerobic performance was assessed with vertical jump test. Periscapular muscles endurance was evaluated using scapular muscle endurance test and agility was measured hexagonal obstacle test. Statistical analysis was performed using the statistical software SPSS 22. Results: Spearman correlation analysis results showed that there was positive significant correlation between anaerobic performance and endurance of periscapular muscles (p<0.05 r=0.341). A negative significant relationship was demonstrated between anaerobic performance and agility (p<0.05 r=-0.332), and between agility and endurance of periscapular muscles (p<0.05 r=-0.334). Discussion: The scapula acts as an axis, transmitting the power and high energy of the lower extremities and trunk to the upper extremities. The muscles surrounding the scapula provide proximal stability for the upper extremity and act as a fix while the distal part is moving. When weakness of scapular musculature has occurred, normal scapular positioning and mechanics may be altered. Therefore, scapular stabilization failure may lead to poor anaerobic performance. These results indicate that periscapular muscle endurance affects anaerobic and agility performance in sports.

Published: March 2017

Purpose: After reconstruction of Anterior Cruciate Ligament (ACL), enlargement of bone tunnel is affected in different rates depending on graft fixation techniques. In this work, we searched the difference of tunnel enlargement between tibial fixation using autologous tibia bone block and tibial fixation using bioscrew. Method: In this prospective work, 48 patients are taken assessment, who were operated because of ACL rupture, from January 2012 to October 2013. The patients are operated by one surgeon and Hamstring tendon is used as graft (semitendinosus folded twice and gracilic tendons). Tibial fixation of 22 patients is ensured by autologous bone block and spiked washers. Tibial fixation of 26 patients is ensured by absorbable bioscrew and “U” nail. In both patient groups, femoral determination is made using sling implant. Between 2 and 2,5 postoperative years, the patients, visualized using computarized tomography, are assessed in enlargement of tibial tunnel diameter. Under clinical circumstances, patients are assessed using Lachman Test and Tegner Activity Score. Results: Sagittal and coronal Computarized Tomography vision of 48 patients, tunnel diameters are measured from 2 cm distal of articular surface, then the percentage of bone enlargement is counted. The tunnel diameter enlargement of 22 patients, to whom autologous bone block is used is %-0,18 in average, but the enlargement of 26 patients, to whom bioabsorbable screw is used, is 9,98 in average. When we compare the two group of tests, it is found that this test is statistically senseful in enlargement of tunnel diameter(p<0,001). When we compare the patients, the enlargement of tunnel gets lesser when we use bone block. According to Lachman test and Tegner Activity Score, it is not found any meaningful difference between two groups. Conclusions: After two years, in comparison with the patients used bioabsorbable screw, the patients, used autologous bone block, encountered lesser bone loss. This method gives a couple of benefits; lesser bone loss lesser enlargement of tunnel diameter, easier surgery revision(although there is no difference clinically), furthermore, it makes the surgery easier because it eliminates one stage of the operation. Besides, the usage of autologous bone block provides meaningful decrease in costs and this is an important advantage.

Published: March 2017

Purpose: The purpose of this study was to evaluate the prevalence and risk factor of cartilage degeneration of patellofemoral joint (PFJ) that was diagnosed by second look arthroscopy in the short term follow-up period. Methods: One hundred seven patients who underwent ACL reconstruction were evaluated by preoperative MRI, postoperative MRI and second-look arthroscopy. Severity of infrapatellar fat pad (IPFP) fibrosis was evaluated by MRI at average of 26 months after ACL reconstruction. Cartilage degeneration was assessed by second look arthroscopy at 29 months. Results: Twenty-five patients (24.0%) showed cartilage degeneration of PFJ in second look arthroscopy. Patients were divided into 3 groups according to severity of IPFP fibrosis tissue i.e. Group A: focal and incomplete band fibrosis, n=69, Group B: complete band fibrosis, n=31, and Group C: diffuse and infiltrated fibrosis, n=7. Cartilage degeneration of PFJ was significantly worsened with more fibrosis formation of IPFP (p<0.001). Other factors for instabilities, BMI, age, concomitant meniscal procedure, time from injury to reconstruction, severity of IPFP fibrosis of preoperative MRI and clinical scores were not correlated with cartilage degeneration of PFJ. The multivariate logistic regression analysis of degeneration of PFJ after ACL reconstruction identified more severe fibrosis tissue formation of IPFP and initial cartilage defect as significant predictors. Conclusions: More extensive fibrosis tissue of IPFP and initial cartilage defect related to further degenerative change of PFJ. Age, BMI, concomitant meniscal procedure, time from injury to reconstruction, clinical scores and instability did not affect cartilage degeneration of PFJ in the short term follow-up period.

Published: March 2017

Robotic surgery studies have been increasing considering operative advantages on reducing error and improving functional success in partial knee arthroplasty. We have been curious whether planning and application of knee implants assisted robotically correspond to their radiological outcomes. Moreover, we were also curious about functional outcomes. Methods: Data were prospectively collected in 42 patients (62 knees) who underwent MAKOplasty, robotic assisted unicondylar medial knee arthroplasty, between June 2013 – December 2015 For evaluation of components’ accuracy, intra-operative robotic analyses were compared with post-operative radiographic alignment. Statistical analysis was done on these values using paired T-Test. Additionally in our clinic with an average follow-up time of 22 months. Clinical outcomes were evaluated with American Knee Society Scoring (AKSS) System. Results: Difference between intra-operative robotic plans and post-operative radiographs was evaluated for the flexion angle of the femoral component, posterior slope of the tibial component and the varus angle of the tibial component. A novel method is used to evaluate the varus angle of the tibial component. All of the errors are <=0.5°, approximately 86% of the errors are <=0.3° while 18% of errors are zero. No significant difference was observed statistically (paired t-test, p<0.05). Post-operatively all 42 patients had excellent knee scores (mean, 99.67) and functional scores (mean, 99.04) on AKSS while pre-operatively 2 were scored fair, 40 were score poor, and functionally 14 were scored fair and 28 were scored poor. Conclusion: The difference between robotic plans and radiographic outcomes was statistically not significant where metal-backed onlay tibial components were used.

Purpose: To evaluate the radiological, clinical results and determine the factors affect implant survival of Oxford phase 3 unicompartmental knee arthroplasty(UKA) which were performed for unicompartmental osteoartrithis between 2011-2016. Materials Methods: In this retrospective study; Oxford phase 3 UKA applied 52 knees of 49 patients with minimum 6 months follow-up were included. Lateral UKA, hemiCAP applied patients not inclueded. Knee Society Score(KSS), functional knee society score(fKSS), Oxford Knee Score(OKS), visual analog scale(VAS) score were pre and postoperatively used. Range of motion(ROM), body mass index(BMI), patello-femoral arthrosis presence were recorded. In radiological evaluation we used posterior tibial slope(PTS), tibial plato angle(TPA), femorotibial angle(FTA) in addition to Oxford radiological criteria. We grouped patients according to their ages, follow-up time, body mass index, radiological criteria, patellofemoral arthrosis presence, complication and revision existence. Clinical, functional results of these groups compared statistically. The factors which affect upcoming of revision by regression analysis and four years survivorship without infirmity by Kaplan-Meier survival analysis were determined. Results: 40 female, 9 male patients inclueded with avarage age, BMI, follow-up time is 60, 34.6, 30 months. OKS, KSS, fKSS, ROM improved significantly from 12.7, 43.3, 34.8,111º preoperatively to 37.8, 85.7, 82, 123º postoperatively. VAS decreased from 9 to 2.6. Not significant differences was found between the age and patellofemaral arthrosis groups. Postop VAS scores were high, knee scores were significantly low at morbid obeses while other BMI groups got perfect knee scores. Knee scores are significantly low, VAS scores are high at patients with femoral component varus is 10º, greater than 10 º, postop TPA is smaller than 85º, higher than 90º. Most frequent mistake was sagittal plane positioning of femoral component. Lateral positioning and more than 10º varus-valgus of tibial component, abnormal PTS, more than 10º varus-valgus of femoral component are the most frequent mistakes of revised knees. All revised cases were in the group that operated at first two years of surgical experience. Postop PTS, TPA, morbid obesity are the most significant factors which affect upcoming revision. Revision ratio is 11.5%. Acccording to Kaplan-Meier survival analysis; 1, 2, 3, 4 years survivorship without any infirmity are 93.7%, 91.5%, 91.5%, 85.7% respectivly. Conclusion: Independent from age, patellofemoral arthrosis; it is possible to achieve perfect results at anteromedial arthrosis with UKA by convenient patient selection, correct surgical technique and improved surgical experience. Postop TPA, PTS and patient based factor morbid obesity are the most important factors for success. [Figure: see text][Figure: see text]

Published: March 2017

Background: There are no clear data whether the season of arthroplasty has any demonstrable effect on the emergence of PJI. In the present study we aimed to explore the effect of the season of arthroplasty surgery on the PJI incidence, and to test if season of arthroplasty is a risk factor for PJI. Material & Method: Our study involved 174 (2.5%) patients with superficial and/or deep infection among 6902 patients who underwent arthroplasty procedure at Taksim First Aid Training and Research Hospital, Baltalimanı Bone Hospital and Medipol University Hospital during an approximately 10-year period between January 2006 and June 2015. Results: An analysis of the timing of the surgeries revealed that the first operations were most commonly performed in February (14.4%) and March (13.8%). The season in which most operations were performed was Spring (n=60; 34.5%) whereas Fall had the least number of operations (n=31; 17.8%) There were also no significant monthly or seasonal differences between the number of infections when separate analyses were done for hip joint (n=88) and knee joint replacements (n=86) (p>0.05) Discussion: Despite the lack of a definitive information about the seasonal predilection of prosthetic joint infections, Kane et al showed a significantly increased incidence of infection in summer months among 750 patients operated with arthroplasty, of whom 17 suffered such infection (15). In contrast, among 174 prosthetic joint infections, we found no significant monthly and/or seasonal difference in the incidence of prosthetic joint infections.Increased moisture and temperature increase bacterial colonization both in the outer environment and on the host’s skin, increasing the sensitivity to infections. Perspiration of the host, closed environmental conditions, and increased moisture are other important factors promoting bacterial colonization (16,17). However, appropriate care of the surgical field following surgery is the most important factor reducing bacterial colonization of skin. Another significant problem with arthroplasty surgery is patient satisfaction, which is promoted by as short as possible waiting times from the time of decision to operate to the time of procedure.In conclusion, the incidence of prosthetic joint infections is not increased after arthroplasty operation in summer when bacterial colonization is promoted by increased temperature and moisture. Therefore, season does not appear as a risk factor.
