Background The aim of the present study was to assess the efficacy of kinesiotherapy used for treating various disorders in athletes on pain and pedal functions in patients with calcaneal apophysitis. Methods This prospective randomized controlled study included 22 patients with calcaneal apophysitis aged 8 to 16 years presenting with heel pain among junior athletes of a professional football club. The patients were randomly grouped into two groups, with one group receiving sham tape only and the other kinesio tape. American Orthopedic Foot & Ankle Society (AOFAS) and visual analog scale (VAS) scores were recorded before and after the treatment. Results The preoperative VAS score of the kinesio tape was 7, and AOFAS score was 62.4; the corresponding figures of the sham group were 6.81 and 70.5, respectively. The kinesio-tape group had a better AOFAS scores at 1st and 3rd month ( p  < 0.05). Posttreatment AOFAS score was 99.7 ± 0.9 for the kinesio-tape group and 97.4 ± 3.9 for the sham-tape group. Posttreatment VAS score was 0.1 ± 0.3 for the kinesio-tape group and 0.4 ± 0.5 for the sham-tape group ( p  > 0.05). Discussion Conservative treatment modalities are preferentially used for its treatment. Kinesiotherapy is one of the treatment methods for the apophysitis. In the literature, our study is the first prospective randomized trial on the efficacy of kinesio taping in calcaneal apophysitis. Conclusions Although kinesio taping can be effectively used for the restoration of ankle functions of athletes with calcaneal apophysitis, its role in pain is limited. Since it lacks serious side effects, it can be used in combination with or as an alternative to pharmacological treatment in this patient group.

Background Although arthroscopic surgical treatment of the first metatarsophalangeal (MTP) joint involves painful sesamoid excision, synovectomy, debridement, and partial cheilectomy, no gold standard treatment technique has been defined in the literature for hallux rigidus and focal osteochondral lesions. This study aimed to assess the arthroscopic treatment for early grade focal osteochondral lesions of the first MTP joint and to determine the impact of arthroscopic microhole drill surgery on foot function and activities of daily living in a group of patients who failed conservative treatment. Methods This prospective study included 14 patients with hallux rigidus and focal osteochondral lesions of the first MTP joint who underwent surgery in 2014 and were followed on a regular basis thereafter. Results The patients had mean preoperative VPS (visual pain score) and AOFAS (American Orthopedic Foot and ankle Society)-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. Discussion In this prospective study, we explored the impact of arthroscopic microhole drill surgery on foot function and activities of daily living in patients with focal osteochondral lesions of the first MTP joint. Our results showed significant improvements in VPS and AOFAS scores with this treatment. Conclusions An arthroscopic microhole drill technique can be used with impressive functional scores and without any complications in patients who failed conservative therapy for hallux rigidus with focal chondral injury.

In this study, mid to long‐term results of anterior cruciate ligament reconstruction with hamstring tendons and Transfix technique were evaluated. Anterior cruciate ligament (ACL) reconstruction with four‐strand hamstring tendon was performed with Transfix technique on 271 (198 males, 73 females; mean age 25.7; 17–52) patients with anterior cruciate ligament ruptures. The patients were followed up with clinical examination, Lysholm and Tegner activity scales, IKDC scoring system, KT‐1000 test and radiological examination. The mean follow‐up period was 82 (48–100) months; 204 (75%) patients had no subjective complaints. According to the KT‐1000 test, only 14 (5%) patients had more than 5 mm laxity postoperatively, whereas, 161 (59%) patients had more than 5 mm laxity preoperatively. In addition to this, only 19 (7%) patients had Lysholm scores less than 80 postoperatively, whereas 154 (57%) patients scored less than 80 preoperatively. When compared with Tegner activity scale, 189 (70%) patients scored <6 preoperatively and only 24 (8%) postoperatively; 78 (29%) patients scored D preoperatively and only 5 (2%) patients scored D postoperatively on the basis of the IKDC scoring system. Our functional results were found to be satisfactory in more than 90% of patients. Commonly seen problems in ACL reconstruction such as inaccurate graft placement and tunnel widening were found to be consistent with the values in relevant literature. However, we demonstrated that the functional results and the stability of the knee were not related with tunnel widening. This study concludes that the reconstruction of ACL with hamstring tendons and the Transfix technique is reasonably successful, safe and causes low morbidity. Furthermore, we believe that proper graft preparation, accurate tunnel placement, notch‐plasty, fixation and rehabilitation program are all as important as the choice of graft and fixation material.

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.

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.

We aimed to evaluate the effects of intertrochanteric femoral fractures on mortality, morbidity, and cost of zoledronate treatment in elderly patients treated by osteosynthesis. Based on Evans classification, 114 patients with unstable intertrochanteric femoral fractures were treated with osteosynthesis. After the surgical treatment of intertrochanteric fractures, the treatment group (M/F, 24/32; mean age, 76.7 ± SD years) received zoledronate infusion, and the control group (M/F, 20/38; mean age, 80.2 ± SD years) received placebo. Postoperative control visits were performed at 6-week, 3-month, 6-month, and 12-month time points. Functional level of patients was evaluated by the modified Harris hip score and Merle d’Aubigné hip score. By 12 months, the mean HHS in treatment and control groups was 81.93 and 72.9, respectively. For time of death of the patients, mortality was found to be 57.1% (16/28) on the first 3 months and 92.9% (26/28) on the first six months. The mortality rate in the treatment and control groups was 14.3% (8/56) and 34.5% (20/58), respectively. The use of zoledronic acid after surgical treatment of intertrochanteric femoral fractures in osteoporotic elderly patients is a safe treatment modality which helps to reduce mortality, improves functional outcomes, and has less side effects with single dose use per year.

Stem cells, with their regeneration capacity, long-term viability, and differentiation characteristics, have indispensable biological properties. As described by Hauner and Grigoradis et al., mesenchymal stem cell originating from adipose or bone marrow can be differentiated into many tissues such as adipocyte, chondrocyte, myeloblast, and osteoblast. The aim of our study is to compare the use of adipose and tibial bone marrow derived stem cells for therapeutic purposes in orthopedic surgery, which has not been clearly evaluated in the literature to our knowledge and to also evaluate their use. Our study was performed between May 2014 and December 2016 in our clinic (Istanbul Medipol University, Department of Orthopedics and Traumatology) in 40 patients. Twelve patients were excluded. The ages of the 28 included patients ranged from 19 to 61 years, with a mean of 41.18 ± 13.39 years. The stem cell samples of these patients were analyzed by flow cytometry. Tibial bone marrow stem cells were used in 15 cases and the mean age was 49.33 ± 9.15. Adipose-derived stem cells were used in 13 patients and the mean age was 31.77 ± 11.25. None of the patients had any minor/major complication in the areas where stem cells were collected. Tibial-derived bone marrow has better results with regard to the complications, economic burden, and surgery time. Tibial-derived bone marrow harvesting and stem cell preparation time are one-fourth of the stem cell treatment prepared from adipose tissue and the surgical duration is shortened by 45 min. If stem cell use is the preference of the surgeon, we have found that the tibial-derived stem cell system is more advantageous for ease of acquisition, cost analysis, and surgical time.

Purpose Osteochondral lesions of the talus are common injuries, and many clinicians consider arthroscopic debridement and microfracture as the first-stage treatment. This study assessed the long-term clinical and radiographic outcomes of arthroscopic debridement and microfracture for osteochondral lesions of the talus. Methods A total of 82 patients (48 males, 34 females) who were treated with arthroscopic debridement and microfracture for osteochondral lesions of the talus between 1996 and 2009 with a minimum 5-year follow-up were included in our study group. Functional scores (AOFAS, VAS) and ankle range of motion were determined, and an arthrosis evaluation was performed. Subgroup evaluations based on age, lesion localization, and defect size were performed using functional outcome correlations. Results The mean age of the patients was 35.9 ± 13.4 years (14–69 years), and the mean follow-up period was 121.3 months (61–217 months). The mean defect size was 1.7 ± 0.7 cm 2 (0.25–5). The mean pre-operative AOFAS score was 58.7 ± 5.2 (49–75), and the mean post-operative AOFAS score was 85.5 ± 9.9 (56–100). At the last follow-up, 35 patients (42.6 %) had no symptoms and 19 patients (23.1 %) had pain after walking more than 2 h or after competitive sports activities. Radiological assessments of arthrosis revealed that no patient had grade 4 arthritis but that 27 patients (32.9 %) had a one-stage increase in their arthrosis level. Subgroup analyses of the lesion location demonstrated that lateral lesions had significantly better functional results ( p  = 0.02). Conclusions Arthroscopic debridement and microfracture provide a good option for the treatment of osteochondral lesions of the talus over the long term in select patients. Functional outcomes do not correlate with defect size or patient age. Orthopaedic surgeons should adopt the microfracture technique, which is minimally invasive and effective for treating osteochondral lesions of the talus. Level of evidence IV.
