ABSTRACT
Introduction The literature is scarce regarding the management of combined tears of scapholunate (SL) and lunotriquetral (LT) ligaments. This study aimed to evaluate our preliminary results with the arthroscopic dorsal ligamentocapsulodesis in managing such cases. Materials and Methods Forty-two patients (13 females, 29 males; mean age = 31; age range = 18-51 years) who underwent arthroscopic dorsal ligamentocapsulodesis due to the combined tears of SL and LT ligaments were retrospectively reviewed. The mean follow-up was 38 (range = 24-55) months. The Modified Mayo Wrist Score, the visual analogue scale (VAS), and grip strength were assessed preoperatively and at the final follow-up examination. Results The mean Modified Mayo Wrist Score significantly improved from 49 (range = 25-70) preoperatively to 82 (range = 60-100) at the final follow-up ( p = 0.000). The mean VAS significantly decreased from 6.33 to 1.6 ( p = 0.000). The mean hand grip strength significantly improved from 31 (range = 19-41) kg to 44 (range = 25-60) kg at the final follow-up examination ( p < 0.001). No major complications were encountered. Conclusion Arthroscopic dorsal ligamentocapsulodesis seems to be a safe and effective surgical technique in the management of this rare combined injury pattern. Level of Evidence This is a Level IV, retrospective case series study.
ABSTRACT
This case report defines an infrequent complication of unicompartmental knee replacement. Periprosthetic supracondylar femoral fracture after total knee replacement is a challenging problem for orthopedic surgeon. To the best of our knowledge, this is the only case describing periprosthetic supracondylar femoral fracture after unicondylar knee replacement.

BACKGROUND: We created patient-based 3D finite-element (FE) models that simulate the congruent-arc Latarjet (CAL) and traditional Latarjet (TL) procedures and then compared their stress distribution patterns with different arm positions and glenoid defects. METHODS: The computed tomography data of 10 adult patients (9 men and 1 woman, ages: 18-50 years) were used to develop the 3D FE glenohumeral joint models. Twenty-five and 35% bony defects were created on the anterior glenoid rim, and the coracoid process was transferred flush with the glenoid by the traditional and congruent-arc techniques using two half-threaded screws. A load was applied to the greater tuberosity toward the center of the glenoid, and a tensile force (20 N) was applied to the coracoid tip along the direction of the conjoint tendon. The distribution patterns of the von Mises stress in the traditional and congruent-arc Latarjet techniques were compared. RESULTS: The mean von Mises on the graft was significantly greater for the TL technique than for the CAL. While the von Mises stress was greater in the distal medial part of the graft in the TL models, a higher stress concentration was observed in the distal lateral edge of the coracoid graft in the CAL models. The proximal medial part of the graft exhibited significantly lower von Mises stress than the distal medial part when compared according to technique, defect size, and arm position. Increasing the glenoid defect from 25 to 35% resulted in a significant increase in stress on the lateral side of the graft in both models. CONCLUSION: The stress distribution patterns and stress magnitude of the coracoid grafts differed according to the procedure. Due to placing less stress on the proximal-medial part of the graft, the CAL technique may lead to insufficient stimulation for bone formation at the graft-glenoid interface, resulting in a higher incidence of graft osteolysis. Clinical relevance The CAL technique may lead to a higher incidence of graft osteolysis. LEVEL OF EVIDENCE: Basic Science Study; Computer Modeling.

We evaluated the long-term functional and cosmetic results of homodigital neurovascular island flap (NIF) used to reconstruct extensive pulp defects with bone exposure in children. Twenty-three children (mean age 4.8 years, range 1-10 years) with fingertip injuries were reconstructed with a pedicled homodigital NIF and evaluated in terms of sensation quality, cold intolerance, scar formation, nail deformity, range of motion and overall finger length at a mean follow up of 7.8 years (range 2-13). Eleven patients reported cold sensitivity in the operated fingertip, and 15 presented with hook nail deformities at the final follow-up. The total active motion of the injured finger was significantly lower than that of the uninjured side (p < 0.001). NIFs is a safe, reliable reconstructive treatment for fingertip loss in children, but commonly encountered issues in the long term include an extension lag of the interphalangeal joints, hook nail deformities and cold intolerance. Level of evidence: IV.

Background: The literature is scarce regarding isolated tears of lunotriquetral interosseous ligament (LTIL). The purpose of this study was to present mid-term clinical and functional results of arthroscopic dorsal ligamentocapsulodesis in the treatment of isolated LTIL tears. Methods: Twenty-two patients (8 females, 14 males; mean age: 31 years; age range: 18-42) with isolated LTIL tears verified by wrist arthroscopy were retrospectively reviewed and included in the study. The mean follow-up was 55 months (range: 24-84). The modified Mayo wrist score, visual analog scale (VAS), flexion and extension deficits of passive wrist range of motion (ROM), pain-free ROM with forced wrist extension and grip strength were measured in all patients preoperatively and at final follow-up. Results: The mean modified Mayo wrist score significantly improved from 50 ± 10.29 preoperatively (range: 30-65) to 86 ± 11.61 (range: 60-100) at the final follow-up (p < 0.001). The mean VAS score significantly improved from 7.1 ± 0.83 (range: 6-8) preoperatively to 2.2 ± 1.35 (range: 0-6; p < 0.001) at the final follow-up. At the final follow-up examination, the forced wrist extension was painless in all but three patients who developed pain at 70º, 75º and 80º of extension, respectively. The mean strength of hand grip significantly increased from 38.6 ± 9.68 (range: 24-54) kg to 49.5 ± 12.36 (range: 33-66) kg at the final assessment (p < 0.001). No major complications were observed during or after the procedure. Conclusions: With the encouraging mid-term outcomes and a lower complication rate, arthroscopic LTIL dorsal ligamentocapsulodesis seems to be a safe and effective surgical technique in improving functional outcomes and reducing pain in patients with isolated LTIL tears. Level of Evidence: Level IV (Therapeutic).

PURPOSE: The etiology of Kienböck disease remains unclear, although mechanical, vascular, and metabolic risk factors have been suggested. We aimed to investigate the association of the angle between the curvatures of the distal radius and the development of Kienböck disease. METHODS: The lunate facet inclination (LFI), scaphoid facet inclination, and interfacet angle (IFA) values were measured using posteroanterior plain radiographs of 82 patients diagnosed with Kienböck disease. The results were compared with normative angular reference values published based on an analysis of 400 wrists of Caucasian patients aged between 20 and 45 years. The posteroanterior radiographs were divided into 3 categories: negative, neutral, and positive based on ulnar variance, and the relationship between ulnar variance and facet angles was evaluated. RESULTS: The IFA value was significantly higher than the normative angular reference value in the patients with Kienböck disease. Conversely, the LFI values were significantly lower in the Kienböck patient group. There were no statistically significant differences in the IFA and LFI values among the ulnar variance groups. CONCLUSIONS: Measuring IFA and LFI allows the evaluation of the bifacet curvature of the distal radius articular surface in the coronal plane. Steep IFA and shallow LFI are associated with Kienböck disease. Increased IFA may lead to abnormal load transmission to the intermediate column, which might eventually lead to increased stress on the lunate. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

OBJECTIVES: The aim of this study was to evaluate the functional results of delayed open reduction and Kirschner wire (K-wire) fixation procedures in patients with delayed presentation of bony mallet finger. PATIENTS AND METHODS: Between February 2009 and November 2019, a total of 19 patients (15 males, 4 females; median age: 24.8 years; range, 14 to 47 years) who were diagnosed with a delayed bony mallet finger and treated with dorsal block pin, direct pinning, or the umbrella handle technique were retrospectively analyzed. The Crawford criteria were used to evaluate the outcomes. The degrees of range of motion (ROM) were measured by a goniometer. RESULTS: The median time from injury to surgery was 41 (range, 28 to 90) days. The median DIP joint extension limitation was 7.63 (range, 0 to 40) degrees and the median ROM of the DIP joint was 66.3 (range, 20 to 90) degrees. There was no statistically significant difference in the postoperative ROM, compared to the uninjured side (p>0.05). The Crawford score was excellent in 11, good in four, fair in three, and poor in one patient. Bone union was achieved in all patients. CONCLUSION: Delayed open reduction and K-wire fixation of chronic bony mallet finger injuries yield successful functional outcomes with low complication rates. Extension lag can be eliminated in most patients by making the joint surface anatomical. The most optimal method should be selected depending on the size of the fracture fragment.

OBJECTIVES: The aim of this study was to evaluate the functional outcomes of patients with free gracilis muscle transfer (FGMT) for the restoration of elbow flexion. PATIENTS AND METHODS: Between January 2012 and January 2019, a total of 16 patients (13 males, 3 females; mean age: 27.3±11.7 years; range: 18 to 53 years) who underwent FGMF to achieve elbow flexion after traumatic brachial plexus palsy (TBPP) were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, etiology, affected side, injury level, accompanying injuries, time between injury and surgery, follow-up time, complications, whether nerve reconstruction and artery repair were performed previously, and details of the procedure were recorded. The outcome measures were elbow range of motion in degrees, muscle strength, and Disabilities of the Arm, Shoulder and Hand (DASH) and Short Form-36 (SF-36) scores. RESULTS: The mean follow-up was 30±11.5 (range, 24 to 42) months. Two patients had C5-C8 injuries, two patients had C6-T1 injuries, and all other patients had injuries to the C5-T1 roots. Muscle strength was M3/M4 in 11 (68.8%) patients, M2 in two (12.5%) patients, and M0 in one (6.2%) patient. The median active range of motion of the elbow joint in patients with successful results (M3 and above) was measured as 75 (range, 30 to 100) degrees. A statistically significant improvement was observed in the pre- and postoperative DASH scores and in some SF-36 subscale scores of patients with successful results. CONCLUSION: Free gracilis muscle flap is a reliable option in the restoration of elbow flexion in patients with TBPP. Although there is an improvement in functional results, disability, and quality of life, there may be no change in patients' mental status and pain.

Radioulnar synostosis is a rare disease which causes supination and pronation restriction as a result of osseous or fibrous connections between the radius and ulna. Radioulnar synostosis includes both congenital and post-traumatic types. Post-traumatic radioulnar synostosis can be seen in the proximal, middle, and distal part of the forearm, depending on the location of the trauma. Congenital proximal radioulnar synostosis occurs as a result of a separation defect between the radius and ulna in the embryonic period. In the presence of congenital proximal radioulnar synostosis, the patient should be evaluated for accompanying syndromes and possible developmental anomalies. In this report, we present a rare case of both proximal and distal radioulnar synostosis. Hypoplasia of the right pectoral muscle mass, hypoplastic appearance of the right nipple, presence of proximal and distal radioulnar synostosis in the right forearm, and accompanying symbrachydactyly suggested Poland syndrome. To the best of our knowledge this is the first case of congenital proximal and distal radioulnar synostosis with Poland syndrome.

INTRODUCTION: The aim of this study is to present various hand reconstruction methods and provide technical notes regarding the treatment of mutilating hand injuries using free-tissue transfers from the foot and to investigate whether these transfers provide patients with a usable hand or not. PATIENTS AND METHODS: Ninety patients with mutilating hand injuries were included in the study. A total of 101 procedures were performed. Patients were contacted by phone to evaluate their working status and to record any complaints regarding their donor sites. The Quickdash questionnaire was conducted for the 53 patients who could be reached. Operative techniques, secondary procedures, finger survival, and physiotherapy data were noted retrospectively. RESULTS: In 36 patients, a trimmed great toe was transferred to the thumb. Second toe-to-thumb transfers were performed in 8 patients, and second toe-to-finger transfers were performed in 10 patients. In 13 patients, 2 toes from one side were transferred, and in 6 patients, 3 toes were transferred to the hand. Bilateral toe transfers were performed in 9 patients. Eight patients underwent joint transfers, of which 2 involved joint transfers from both feet. The overall finger survival rate for the transfer procedures was 95.04%. The average Quickdash score of the patients who could be reached (n = 53) was 27.49, with 62.3% of the patients being able to use their hands in their previous jobs, and 26.4% needing to change their jobs because of their hand injuries. 41.5% of the patients had no donor site complaints. 47.2% had mild complaints, and 11.3% had major donor site complaints. CONCLUSION: Multiple-toe transfer techniques along with flap coverage options should be considered, and delicate planning is mandatory to achieve at least a basic or acceptable hand. Three toes, including the great toe, can be transferred in a single operation by dissecting both the dorsal and plantar arterial systems. Crush injuries of the dorsal side of the hand may be reconstructed using combined transfers of bones, joints, extensor tendons, and skin. In our series, 88.7% of patients with mutilating hand injuries were able to return to work after we performed tissue transfers from the foot.

BACKGROUND: Covering soft tissue defects of the distal one-third of the leg and the Achilles tendon region and is a challenging problem for an orthopedic surgeon. With recent advancements in the anatomical knowledge of perforating vessels, perforator-pedicled propeller flaps have become increasingly popular in recent decades. We aimed to evaluate the clinical outcomes of our patients whose soft tissue defects in the distal leg were reconstructed with propeller flaps and assessed association of complications with age, gender, flap size and arc of rotation. METHODS: Patients that had a reconstruction with a propeller flap at the ankle from 2013 to 2019 were retrospectively reviewed. The main indications for the propeller flap were small- and medium-sized soft tissue defects of the distal lower limb. 20 propeller flaps were applied to 19 patients (14 male, 5 female) for various lower extremity defects. RESULTS: The mean follow-up duration was 2 years (range, 6 months to 6 years). The average flap size was 82 cm2 (range, 48-125 cm2). The flap was rotated 180 degrees in nine patients The source of the perforator vessel was the tibialis posterior artery in 14 cases, the peroneal artery in 4 cases, both the tibialis posterior and peroneal arteries in 1 case. Four complications (20 %) occured postoperatively. Two patients developed partial necrosis at the tip of the flap, and two patients developed superficial epidermolysis. No correlations were found between complications and flap size and the arc of rotation. CONCLUSIONS: The propeller flap is a reliable option for reconstruction of small to moderate defects in the lower extremity with good clinical results and minimal donor-site morbidity. It is applicable for orthopedic surgeons who do not have microsurgical experience or an available microscope in the operating room.

OBJECTIVES: This study aims to analyze the nationwide trends in carpal tunnel surgery by surgeons practicing in Turkey according to experience in years, training received (plastic surgery or orthopedics), and working location (Turkey or abroad) by slightly modifying Munns' survey. MATERIALS AND METHODS: A printed and online survey consisting of 11 questions was sent to Turkish and international surgeons. The surgeon's province of practice, years in practice, type of education received as a resident, preferred operation room, preferred surgical approach, type of anesthesia used, use of postoperative orthosis and therapy were assessed in the survey. RESULTS: The survey was completed by 198 surgeons (a 25% response rate). The majority of surgeons practicing in Turkey (87%) and 67% of surgeons practicing abroad demanded electromyography (EMG) and nerve conduction studies. Sixty- one percent of respondents from Turkey and 76% of respondents practicing abroad did not administer antibiotics preoperatively. While the most common anesthetic technique used by international surgeons was subcutaneous local anesthesia (42%), Turkish surgeons preferred wrist block (18%). Surgeons practicing in Turkey with fewer than five years of experience were more likely to administer antibiotics preoperatively, use EMG/nerve conduction studies, utilize a mini-open approach and apply an orthosis postoperatively (p<0.05). CONCLUSION: There are comparable differences between Turkish and international surgeons regarding pre- and postoperative management of carpal tunnel surgery. Province of practice, years in practice, and type of education received as a resident have influence over the management of carpal tunnel syndrome.

OBJECTIVE: This study aimed to compare the perioperative clinical outcomes of trephine biopsy (TB) with the conventional open surgical method (COSM) in bone graft harvesting from the olecranon. METHODS: In this retrospective study, 130 patients who underwent bone graft harvesting from the olecranon using either TB or COSM were included. Patients were then divided into two groups: the COSM group (48 patients; 36 men and 12 women; mean age=32 years; age range=18-52) and the TB group (82 patients; 61 men and 21 women; mean age=34 years; age range=20-62). The mean follow-up was 30 months (range=17-57) in the COSM group and 26.8 months (range=6-48 months) in the TB groups. The two groups were compared in terms of pain intensity, operating time, complication rate, elbow range of motion, and the scar sensitivity of the graft donor site. Pain intensity was measured using the visual analogous scale (VAS) on postoperative days 1 and 15. Other outcome measures were evaluated at the final follow-up. RESULTS: In the TB group, the mean VAS score was 4±1.62 on postoperative day 1 and 1.6±0.76 on postoperative day 15. In the COSM group, the mean VAS score was 7.2±1.38 on postoperative day 1 and 3.1±1.34 on postoperative day 15. The early VAS scores were significantly higher in the COSM group than in the TB group (p<0.05). The mean operating time was 7±1.99 minutes in the TB group and 20±4.51 minutes in the COSM group. Hematoma occurred in one patient from each group, with an incidence of 2.1% in the COSM group and 1.2% in the TB group. There was no significant difference between the two groups regarding elbow range of motion at final follow-up p>0.05). No patient in the TB group showed sensitivity of the scar region, while scar sensitivity occurred in 3 of 48 patients (0.6%) in the COSM group. CONCLUSION: Compared with COSM, TB seems to be a safe technique with similar complication rates. TB can provide shorter operating time, less postoperative pain, and smaller and less sensitive scar compared with COSM. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

OBJECTIVES: The aim of this study was to evaluate Turkish trends in zone 2 flexor repair with regards to surgical technique, suture materials, anesthesia and post-operative rehabilitation and compare this with international surgeons by modifying Gibson's survey. METHODS: A printed and online survey consisting of 19 questions modified from Gibson's survey was sent to 590 Turkish and international surgeons. The surgeon's years in practice, province of practice, residency type, number of zone 2 flexor tendon repairs done in a year, preferred surgical technique, suture material, complications and postoperative protocols were asked to the respondents. RESULTS: A total of 194 surgeons completed the survey (a 25% response rate). Of those who completed the survey, 91 were international (mostly from far eastern countries) and 103 were Turkish surgeons. Years in practice and educational background had influence on the decision-making. There were differences between the Turkish and international surgeons in the core and epitendinous suture thickness preference and flexor tendon sheath repair. There was a statistically significant relationship between the province of practice and the use of WALANT (Wide awake local anesthesia no tourniquet) (p < 0.05). While the majority of respondents who preferred postoperative early passive motion protocol were from Turkey (61.5%), the majority of respondents who preferred early active motion protocol were practicing abroad (73.9%). CONCLUSION: Despite some variations the surgeons involved in this study follow to a large extent the current literature.

Mouse digit tip regeneration involves an intricate coordinated regrowth of the terminal phalanx, nail, dermis and epidermis. During this time, regenerating digits undergo wound healing, blastema formation, and differentiation. However, the regenerative response of the digit is dependent on the level of the amputation. Amputation of <30% of the distal phalanx (P3), with part of the base nail remaining, results in extensive digit regeneration. In contrast, >60% P3 removal results in no regeneration. This level-dependent regenerative ability of the mouse digit provides a comparative model between regeneration and non-regeneration that may enable identification of specific factors critical to regeneration. Although the ability to create regenerating and non-regenerating conditions has been well established, the regenerative response between these regions ("intermediate" zone) has received less scrutiny, and may add insight to the regenerative processes, including the degree of histolysis, and the level of blastema formation. The objective of this study is then to compare the regeneration capacity between amputation levels within the regenerating (<30%), intermediate (40-59%), and non-regenerating (>60%) regions. Results indicated that regenerative and intermediate amputations led to significant histolysis and blastema formation of the distal phalanx 14 days post-amputation. Unlike the regenerating digits, intermediate amputations led to incomplete regeneration whereby regrowth of the digits were not to the levels of the intact or regenerating digits. Non-regenerating amputations did not exhibit significant histolysis or blastema formation. Remarkably, the histolytic process resulted in day 14 P3 lengths that were similar regardless of the initial amputation over 19%. The differences in histolysis, blastema formation and injury outcomes were also marked by changes in the number of proliferating cells and osteoclasts. Altogether, these results indicate that although intermediate amputations result in histolysis and blastema formation similar to regenerating digits, the resulting cellular composition of the blastema differs, contributing to incomplete regeneration.

BACKGROUND: This study aimed to evaluate the long-term follow-up results of V-Y tendon plasty with fascia turndown, for repairing chronic Achilles tendon ruptures. METHODS: Seventeen patients (12 males, 5 females), who were diagnosed with chronic Achilles tendon rupture and met the inclusion criteria, were included in the study. These patients received treatment by means of V-Y tendon plasty with fascia turndown from January 1995 to December 2001. Clinical outcomes of the patients were assessed by using isokinetic strength testing, questioning the patient regarding residual discomfort, pain, or swelling and having the ability to perform heel rises and using American Orthopaedic Foot & Ankle Society's (AOFAS's) Ankle-Hind Foot Scale score. Mean follow-up duration was 16 years (13-18 years). RESULTS: Mean time from the injury to operative treatment was 7 months. Mean operative defect of Achilles tendon in neutral position after debridement was 6 cm. During the follow-up, the mean calf atrophy was 3.4 cm. The mean 30 degrees/s plantarflex and 120 degrees/s plantarflex peak torques were 89 and 45 Nm, respectively. The mean 30 degrees/s plantarflex peak torque deficiency was 16%. The mean 120 degrees/s plantarflex peak torque deficiency was 17%. The average peak torque deficiency was 17%. The pre- and postoperative mean AOFAS Ankle-Hindfoot Scale scores were 64 and 95, respectively. No patient had a rerupture. Superficial wound infection was treated with oral antibiotic therapy in 2 patients (11%). CONCLUSIONS: The V-Y tendon plasty with fascia turndown for repairing chronic Achilles tendon ruptures yielded results comparable with the literature regarding clinical outcomes. This method did not require synthetic materials for augmentation and was an economic alternative compared to other repair methods. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

BACKGROUND: Disruption of the periosteum has been used to explain overgrowth after long bone fractures. Clinically, various periosteal procedures have been reported to accelerate growth with varied results. Differences between procedures and study populations, in these prior studies, make drawing conclusions regarding their effectiveness difficult. QUESTIONS/PURPOSES: The purpose of this study was to (1) determine if all reported periosteal procedures accelerate growth and increase the length of bones; (2) study the relative duration of these growth-accelerating effects at two time points; and (3) identify the periosteal procedure that results in the most growth. METHODS: Periosteal stripping (N = 8), periosteal transection (N = 8), periosteal resection (N = 8), (and) full periosteal release (N = 8) were performed on the tibiae of skeletally immature rabbits. Tibiae were collected 2 weeks postoperatively. The tibiae of additional cohorts of periosteal transection (N = 8), periosteal resection (N = 8), full periosteal release (N = 8), and repetitive periosteal transection (N = 8) were collected 8 weeks postoperatively. The contralateral tibiae served as an operative sham control in all cohorts. Fluorochrome bone labeling was used to measure growth rates, whereas high-resolution Faxitron imaging was performed to measure tibial lengths. Comparisons were then made between (1) experimental and sham controls; and (2) different procedures. Eight additional nonsurgical animals were included as age-matched controls. RESULTS: Growth (in microns) was accelerated at the proximal tibial physis on the tibia undergoing the periosteal surgical procedures versus the contralateral control limb after the transection (411 ± 27 versus 347 ± 18, p < 0.001 [mean ± SD]), resection (401 ± 33 versus 337 ± 31, p < 0.001), and full periosteal release (362 ± 45 versus 307 ± 33, p < 0.001), 2 weeks after the index procedure. Conversely, the periosteal stripping cohort trended toward less growth (344 ± 35) than the controls (356 ± 25; p = 0.08). No differences were found between limbs in the nonoperative controls. Tibial lengths for the experimental tibiae were longer at 2 weeks in the transection (1.6 ± 0.4 mm, p < 0.001), resection (1.6 ± 0.9 mm, p = 0.03), and full periosteal release (1.7 ± 0.5 mm, p < 0.001), whereas negligible differences were found between the tibiae of the nonoperative controls (0.13 ± 0.7 mm, p = 0.8) and stripping cohorts (0.10 ± 0.6 mm, p = 0.7). At 8 weeks, growth acceleration ceased at the proximal tibial physes in the transection cohort (174 ± 11 versus 176 ± 21, p = 0.8), and the control limbs actually grew faster than the experimental limbs after resection (194 ± 24 versus 178 ± 23, p = 0.02) and full periosteal release (193 ± 16 versus 175 ± 19, p < 0.01) cohorts. Growth rates were increased over control limbs, only in the repetitive transection cohort (190 ± 30 versus 169 ± 19, p = 0.01) at 8 weeks. Tibial lengths for the experimental tibiae remained longer at 8 weeks in the transection (1.4 ± 0.70 mm, p < 0.001), resection (2.2 ± 0.82 mm, p < 0.001), full periosteal release (1.6 ± 0.42 mm, p < 0.001), and repetitive periosteal transection (3.3 ± 1.1 mm, p < 0.001), whereas negligible differences were found between the tibiae of the nonoperative controls (-0.08 ± 0.58 mm, p = 0.8). Comparing the procedures at 2 weeks postoperatively, no differences were found in tibial lengths among the transection (2.1% ± 0.5% increase), resection (2.1% ± 1.1% increase), and full periosteal release (2.1% ± 0.6 %); however, all three demonstrated greater increased growth when compared with the stripping cohort (-0.10% ± 0.7%; p < 0.05). At 8 weeks no differences could be found between increased tibial lengths among the transection (1.5% ± 0.7%), resection (2.3% ± 0.9%), and full periosteal release (1.7% ± 0.4%). The repetitive transection produced the greatest over length increase (3.5% ± 1%), and this was greater than the acceleration generated by the single resection (p < 0.001) or the full periosteal release (p = 0.001). All four demonstrated an increase greater than the nonoperative control (0.09% ± 0.6%; p < 0.05). CONCLUSIONS: Transection of the longitudinally oriented periosteal fibers appears critical to accelerate growth in a rabbit model. CLINICAL RELEVANCE: These findings in an animal model support previous claims that limb overgrowth occurs as the result of periosteal disruption. Based on these findings in rabbits, we believe that less invasive procedures like periosteal transection are a promising avenue to explore in humans; clinical studies should seek to determine whether it is equally effective as more invasive procedures and its role as an adjunct to guided growth or distraction osteogenesis.

Between 2006 and 2011, 102 hips of 78 patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip (DDH) underwent cementless total hip arthroplasty (THA). According to the Crowe's classification, 22 hips (21%) were type 1, 19 hips (18%) were type 2, 22 hips (21%) were type 3 and 39 hips (38%) were type 4 respectively. Functional and clinical analyses were performed by Harris Hip Scores (HHS). There were 73 (71%) excellent or good results according to HHS. The postoperative HHS was significantly lower in patients who underwent femoral shortening (p<0.01). We observed 25 (24.5%) complications in total, 15 (14.7%) of which required revision surgery. The authors concluded that THA for DDH is a safe and a reliable procedure with good clinical outcomes.

OBJECTIVE: The aim of this retrospective, observational study was to describe the outcomes of total knee replacement (TKR) after failed Oxford phase 3 medial unicompartmental knee replacement (UKR). METHODS: The study included 24 revision TKRs (20 females, 4 males; mean age: 61 years) performed following failed aseptic UKR. Outcomes were assessed using the Knee Society Score (KSS). RESULTS: The most common causes for revision were mobile bearing dislocation and unexplained pain. Mean preoperative KSS was 50.3 (range: 37 to 66) and 82.2 (range: 58 to 97) after TKR. There were 17 excellent, 4 good, 2 fair and 1 poor results. CONCLUSION: The type of UKR performed (cemented versus uncemented) had no effect on TKR success. Revision for failed UKR with TKR appears to be a technically straightforward procedure with satisfactory early clinical results.
