Long-term Outcomes of Tibial Spine Avulsion Fractures After Open Reduction With Osteosuturing Versus Arthroscopic Screw Fixation: A Multicenter Comparative Study.

Background: More information is needed regarding return to preinjury sport levels and patient-reported outcomes after tibial spine avulsion (TSA) fracture, which is most common in children aged 8 to 12 years. Purpose: To analyze return to play/sport (RTP), subjective knee-specific recovery, and quality of life in patients after TSA fracture treated with open reduction with osteosuturing versus arthroscopic reduction with internal screw fixation. Study Design: Cohort study; Level of evidence, 3. Methods: This study included 61 patients <16 years old with TSA fracture treated via open reduction with osteosuturing (n = 32) or arthroscopic reduction with screw fixation (n = 29) at 4 institutions between 2000 and 2018; all patients had at least 24 months of follow-up (mean ± SD, 87.0 ± 47.1 months; range, 24-189 months). The patients completed questionnaires regarding ability to return to preinjury-level sports, subjective knee-specific recovery, and health-related quality of life, and results were compared between treatment groups. Univariate and multivariate logistic regression analyses were conducted to determine variables associated with failure to return to preinjury level of sport. Results: The mean patient age was 11 years, with a slight male predominance (57%). Open reduction with osteosuturing was associated with a quicker RTP time than arthroscopy with screw implantation (median, 8.0 vs 21.0 weeks; P < .001). Open reduction with osteosuturing was also associated with a lower risk of failure to RTP at preinjury level (adjusted odds ratio, 6.4; 95% CI, 1.1-36.0; P = .035). Postoperative displacement >3 mm increased the risk of failure to RTP at preinjury level regardless of treatment group (adjusted odds ratio, 15.2; 95% CI, 1.2-194.9; P = .037). There was no difference in knee-specific recovery or quality of life between the treatment groups. Conclusion: Open surgery with osteosuturing was a more viable option for treating TSA fractures because it resulted in a quicker RTP time and a lower rate of failure to RTP as compared with arthroscopic screw fixation. Precise reduction contributed to improved RTP.

Management of anterior thigh injuries in soccer players: practical guide.

Most of the anterior thigh injuries are contusions or strains, however, some of these injuries can be career ending. Early diagnosis and correct treatment are key to successful outcome. Analyzing injury mechanism and adding both clinical and imaging findings, clinicians can make the right treatment decisions already often in the acute phase of the injury. Low grade contusions and muscle strains are treated well with planned rehabilitation, but complete tendon injuries or avulsions can require operative treatment. Also, neglected minor injuries could lead to chronic disabilities and time lost from play. Typical clinical presentation of anterior thigh injury is swelling and pain during hip flexion or knee extension. In more severe cases a clear gap can be palpated. Imaging methods used are ultrasound and magnetic resonance imaging (MRI) which are helpful for clinicians to determine more exact the extent of injury. MRI can identify possible tendon retractions which may need surgery. Clinicians should also be aware of other traumatic lesions affecting anterior thigh area such as myositis ossificans formation. Optimal treatment should be coordinated including acute phase treatment with rest, ice, and compression together with designed return-to-play protocol. The anatomical structure involved lines the treatment pathway. This narrative review describes these more common reasons for outpatient clinical visits for anterior thigh pain and injuries among soccer players.

Calcaneal Bone Bruise After Surgery for Insertional Achilles Tendinopathy.

OBJECTIVE: Excision of the posterosuperior corner of the calcaneus (EPCC) is routinely undertaken in athletes after failure of conservative management of insertional Achilles tendinopathy. Some patients can experience sharp calcaneal pain during postoperative rehabilitation, a sign of a calcaneal bone bruise (CBB). DESIGN: Case series, level of evidence IV. SETTING: University teaching hospital. PATIENTS: This study reports 8 patients who developed postoperative CBB after having started impact training too early. INTERVENTION: Patients in whom a diagnosis of CBB had been formulated were followed to return-to-play and resolution of bone edema by MRI. MAIN OUTCOME MEASURES: Detection of CBB after EPCC. RESULTS: After routine EPCC for insertional Achilles tendinopathy, 8 patients presented with sharp pain for a mean 7.1 weeks (median 6 weeks, range 5-11 weeks) before clinical suspicion of CBB. At that stage, MRI showed clear evidence of a bone bruise, with a diagnosis of CBB formulated at an average of 10.8 postoperative weeks (range 6-16 weeks). Calcaneal bone bruise resolved with modified symptom-free loading. Patients returned to play at average on 5.6 months (range 2-9 months) after the diagnosis of postoperative CBB. CONCLUSIONS: We describe 8 athletes who developed painful CBB following routine EPCC for insertional Achilles tendinopathy after having increased their level of activities too soon after the index procedure. In these patients, the diagnosis of postoperative CBB can be formulated by MRI and more cautious rehabilitation implemented.

Proximal Adductor Longus Tendon Repair With a Concomitant Distal Fascial Release for Complete Hip Adductor Tendon Tears: Surgical Technique and Outcomes in 40 Male Athletes.

BACKGROUND: The optimal treatment for complete avulsions of the proximal adductor longus (AL) is still debatable, and different operative and nonoperative treatment options have been suggested. PURPOSE: To report surgical techniques and functional outcomes of a series of athletes who were treated operatively for proximal AL tears. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A retrospective evaluation of patients who underwent surgical repair of complete proximal AL tear with concomitant distal fascial release with or without lesions of the neighboring soft tissue structures was performed. This included preinjury Tegner score, age, number of tendons involved, time interval from injury to surgery, and postoperative complications. Self-reported outcomes were defined based on the ability to regain sports activities (excellent, good, moderate, fair, or poor). Between-group comparisons were performed to identify factors associated with improved outcomes. The Mann-Whitney nonparametric test was used for comparing continuous variables, and the Fisher exact test was used for comparing nominal variables. RESULTS: A total of 40 male athletes were included in the evaluation, with an average follow-up of 11 months (range, 6 months-8 years). Self-reported outcome was excellent in 23 (57.5%), good in 13 (32.5%), and moderate in 4 (10%) patients. Comparisons between patients with excellent versus good/moderate outcomes revealed nonsignificant differences regarding age at injury and preinjury Tegner score. Athletes with excellent outcomes received surgery sooner after the injury compared with athletes with good/moderate outcomes (2.4 ± 1.8 vs 11.4 ± 11.0 weeks, respectively; P < .01). CONCLUSION: Surgical repair for complete proximal AL tears with a concomitant distal fascial release resulted in outcomes rated as good or excellent in 90% of the cases. This treatment should be considered particularly in high-level athletes with a clear tendon retraction and within the first month after the injury. Further research is nevertheless needed to compare these outcomes with other treatment alternatives to better define criteria advocating surgery.

Chronic and Recurrent Rectus Femoris Central Tendon Ruptures in Athletes: Clinical Picture, MRI Findings, and Results of Surgical Treatment.

BACKGROUND: Severe rectus femoris central tendon rupture is an uncommon sports-related injury. Most rectus femoris central tendon injuries can be treated by nonoperative means, but some tend to reinjure, resulting in chronic symptoms. Physicians treating athletes with rectus femoris injuries should be aware of this clinical condition and know that surgical treatment could be beneficial to the athlete if the rectus femoris central tendon rupture becomes chronic. PURPOSE: To describe the clinical picture, magnetic resonance imaging (MRI) findings, and surgical treatment results of rectus femoris central tendon injuries. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: This study included 12 patients who underwent successful repair of recurrent rectus femoris central tendon rupture. Presurgical MRI scans were obtained and compared with the surgical findings. The time of return to play was recorded, and the outcome of surgical treatment was evaluated with validated Subjective Patient Outcome for Return to Sports (SPORTS) criteria: good = full return to preinjury level of sports without any symptoms; moderate = return to preinjury level of sports with some residual symptoms (mild discomfort during sports); and poor = did not return to preinjury level of sports. RESULTS: Overall, 10 patients had a good outcome (83%), and 2 had a moderate outcome (17%). All athletes included in the study were able to return to sport at their preinjury levels 2.5 to 4 months postoperatively. Presurgical MRI scans correlated well with the surgical findings. CONCLUSION: The surgical treatment of rectus femoris central tendon rupture seems to be a good option in chronic and recurrent cases. After surgery and successful rehabilitation, the athlete is expected to continue sports at the preinjury level.

Tears of biceps femoris, semimembranosus, and semitendinosus are not equal-a new individual muscle-tendon concept in athletes.

OBJECTIVES: Hamstring injuries are common and can now be accurately diagnosed. In addition, novel surgical indications have been introduced. However, evidence-based guidelines on the hamstring injuries in management of top-level athletes are missing. METHODS: The management methods and outcomes of treatment are classically based on relatively small case series. We discuss a novel concept based on the fact that each tendon of the hamstrings muscle should be managed in an individual fashion. Furthermore, suitable indications for hamstring surgery in athletes are introduced. RESULTS: The present study introduces modern treatment principles for hamstring injury management. Typical clinical and imagining findings as well as surgical treatment are presented based on a critical review of the available literature and personal experience. CONCLUSIONS: Hamstring injuries should not be considered to be all equal given the complexity of this anatomical region: The three separate tendons are different, and this impacts greatly on the decision-making process and outcomes in athletes.

Operative Treatment of Proximal Rectus Femoris Injuries in Professional Soccer Players: A Series of 19 Cases.

BACKGROUND: Proximal rectus femoris (PRF) tears are relatively rare injuries among top-level athletes. PRF injuries can be avulsions of both tendon heads (direct and reflected heads) or of a single head, and some have a tendency to progress to recurrent injuries. PURPOSE: To describe a series of operatively treated PRF ruptures in professional soccer players. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Nineteen cases of PRF injuries (18 patients, 1 bilateral) in professional soccer players who were treated surgically were retrospectively reviewed. Perioperative findings with return-to-play data were recorded. RESULTS: Of the PRF injuries, 10 total avulsions (both heads) and 9 single-head tears were seen on magnetic resonance imaging and were later confirmed during surgery. All 18 patients returned to their preinjury level of play (mean follow-up, 2.8 years [range, 1-11 years]). CONCLUSION: The repair of PRF tears in professional soccer players yielded good results and allowed all patients to return to their preinjury level of play.

Central Tendon Injuries of Hamstring Muscles: Case Series of Operative Treatment.

BACKGROUND: As compared with injuries involving muscle only, those involving the central hamstring tendon have a worse prognosis. Limited information is available regarding the surgical treatment of central tendon injuries of the hamstrings. PURPOSE: To describe the operative treatment and outcomes of central tendon injuries of the hamstrings among athletes. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Eight athletes (6 top level, 2 recreational) with central hamstring tendon injuries underwent magnetic resonance imaging and surgical treatment. The indication for surgery was recurrent (n = 6) or acute (n = 2) central hamstring tendon injury. All patients followed the same postoperative rehabilitation protocol, and return to play was monitored. RESULTS: Magnetic resonance imaging found a central tendon injury in all 3 hamstring muscles (long head of the biceps femoris, semimembranosus, and semitendinosus) with disrupted tendon ends. In acute and recurrent central tendon injuries, full return to play was achieved at 2.5 to 4 months. There were no adverse events during follow-up. CONCLUSION: Central tendon injuries of the hamstrings can be successfully repaired surgically after acute and recurrent ruptures.

Arthroscopic Coracoclavicular Ligament Reconstruction Using a Synthetic Polycaprolactone-Based Polyurethane Urea Tendon Graft: A Report of 5 Cases.

BACKGROUND: Several techniques have been introduced to treat acromioclavicular (AC) separation using the semitendinosus tendon as a graft for coracoclavicular (CC) ligament reconstruction. However, the tendon may have been used previously or the patient may not want it harvested. Hence, synthetic tendon transfers have become increasingly popular. METHODS: Five patients with chronic AC separations were treated. A synthetic polyurethane urea tendon graft (Artelon Tissue Reinforcement [ATR]) was chosen for its ability to partially transform into connective tissue. The patient follow-up period lasted 45 to 60 months. RESULTS: The mean preoperative Constant Score increased from 64.8 to 100 postoperatively. The mean preoperative Simple Shoulder Test increased from 7.2 to 12 postoperatively. The mean postoperative increase of the CC distance was 1.5 mm. The mean expansion of the clavicular drill hole from the original was 2.1 mm. According to the postoperative magnetic resonance imaging, the grafts had healed well and the cross-sections of the grafts were up to 10.5 mm between the coracoid and the clavicle. DISCUSSION: The synthetic ATR tendon strip was a practical method for reconstructing a torn CC ligament complex. The ATR graft appears promising for future CC ligament reconstructions.

Operative treatment of pelvic apophyseal avulsions in adolescent and young adult athletes: a follow-up study.

INTRODUCTION: Pelvic apophyseal avulsion can limit young athletes' performance for months and may result in permanent disability. Nonoperative treatment is most commonly preferred, while surgical management with reduction and fixation is reserved for selected cases. Our aim was to evaluate outcomes of operative management of pelvic apophyseal avulsions in a series of adolescents and young adult athletes. MATERIALS AND METHODS: Operative room registries and medical records were reviewed to identify patients who received surgical treatment for pelvic apophyseal avulsions who were younger than 24 years and with a minimum of 12 month follow-up. RESULTS: Thirty-two patients (16.8 years ± 2.6) were identified. The most common avulsion sites were anterior inferior iliac spine (34.4%, N = 11) and ischial tuberosity (34.4%, N = 11). Other avulsions were five cases (15.6%) of the pubic apophysis, four cases (12.5%) of the anterior superior iliac spine apophysis and one case of the iliac crest apophysis. Seventeen cases (53.1%) underwent surgery early, i.e., during the first 3 months after the acute injury. Twenty-two cases (68.8%) involved reduction with internal fixation, and six cases (18.8%) involved resection of the fragment. Twenty-six athletes (81.3%, N = 26) reported good outcomes and were able to return to preinjury sports level. Six patients (18.8%) had moderate outcome and reported activity limitations during high-level sports. Large displacement (> 20 mm) or delayed (> 3 months) surgery was not associated with inferior outcomes (P = 0.690 and P = 0.392, respectively). Injury side (P = 0.61) or gender (P = 0.345) did not affect outcomes. CONCLUSIONS: Operative management of pelvic apophyseal avulsion results in return to the preinjury sports level in more than 80% of the cases. However, while both acute surgery for large displacement and delayed intervention for failed nonoperative treatment are generally successful in improving sports function in these cases, comparative studies are required to refine criteria for surgery. LEVEL OF EVIDENCE: Case series, IV.

Surgical excision of symptomatic mature posttraumatic myositis ossificans: characteristics and outcomes in 32 athletes.

PURPOSE: The purpose of this study was to report characteristics and outcomes of surgical excision of symptomatic mature posttraumatic myositis ossificans in adult athletes. The hypothesis was that surgical excision of the ossified mass in these circumstances can effectively relief symptoms and result in return to high-level sports with minimal postoperative complications. METHODS: All operations involving excision of posttraumatic heterotopic ossifications performed between 1987 and 2015 were reviewed. Included cases had isolated excision of posttraumatic myositis ossificans, whereas excluded cases had: (1) concomitant reattachment of tendon to bone; (2) chronic overuse injuries which preceded the development of the heterotopic mass or large calcifications which were excised from tendon-to-bone insertions; and (3) excision of heterotopic ossification from a ligament, capsule, or tendon insertion following avulsion injury without tendon-to-bone repair. After surgery, return to sports was allowed at 4-6 weeks. RESULTS: Of 57 athletes undergoing excision of heterotopic ossifications, 32 were eligible as isolated excision of posttraumatic myositis ossificans. Twenty-four (75%) were ice hockey or soccer players. Median age was 23 years. Prior to surgery, patients were unable to continue their sports. At surgery, the ossification was excised from a thigh muscle in 27 (84%) cases. Median follow-up was 2 years (range 1-20 years). Outcome was Good/Excellent in 26 (81%) patients, corresponding to return to preinjury sports with minimal symptoms at sports activities. Preinjury Tegner activity level was resumed after surgery in 30 of 32 (94%) athletes, of whom 28 (94%) were involved in high-level sports corresponding to Tegner levels 8-10. No postoperative complications were recorded other than minimal insensitive areas at the periphery of skin incisions. CONCLUSION: In high-level athletes who present chronic disabling mature posttraumatic myositis ossificans that interferes with their sports career, surgical excision of the heterotopic mass results in effective clinical improvement with return to sports and minimal postoperative risks. LEVEL OF EVIDENCE: Case series, Level IV.

Survival of uncemented cups from a single manufacturer implanted from 1985 to 2013: Finnish Arthroplasty Register data.

INTRODUCTION: Total hip arthroplasty (THA) with uncemented implants has been a relatively common procedure in Finland during the recent decades. The most common brand of uncemented implants was chosen for further analysis to study the survivorship of this uncemented cup design in comparison to cemented references. PATIENTS, MATERIALS AND METHODS: Since 1980, The Finnish Arthroplasty Register has collected information on THAs on a national level. This study was based on information of THAs recorded in the Finnish Arthroplasty Register from 1985 to 2013. If patient had undergone bilateral THA, only the first one was included. Altogether, 49,289 THAs were included. RESULTS: The overall 10-year implant survivorship of uncemented implants was 84.3% (95% CI 83.5-85.0%) and of cemented implants 90.6% (90.2-90.0%). The 10-year survival of the contemporary uncemented implants was 90.8% (94.0-95.5%) and 88.5% (84.2-91.7%). The most recently introduced uncemented cup designs had good survivorship rates at 5 years; 10-year survival data are not yet available. CONCLUSIONS: We found that modern uncemented cup designs may provide good long-term survivorship rates comparable with the gold standard of cemented cups. However, polyethylene wear, liner problems and periosthetic osteolysis may still occur, also with modern uncemented acetabular components.

Different distributions of operative diagnoses for Achilles tendon overuse injuries in Italian and Finnish athletes.

BACKGROUND: the origin of chronic Achilles tendinopathy (AT) is currently unclear and epidemiological factors, such as ethnicity, may be associated. METHODS: intraoperative findings from the treatment of 865 Finnish and 156 Italian athletic patients with chronic Achilles tendon related pain were evaluated, retrospectively. The mean age was 34 years (range, 18 to 65 years) in the Finnish and 29 years (range, 17-63 years) in the Italian patients. In total, 786 patients were males and 226 females of which 84 and 87% Finnish, respectively. Data were collected, retrospectively from patient records. The differences in the frequencies of operative findings were assessed for statistical significance. RESULTS: retrocalcaneal bursitis, partial tear and chronic paratenonitis were the most prevalent findings in patients with chronic AT undergoing surgery. Tendinosis and chronic paratenonitis were significantly (p=0.011) more common in Finnish athletes. Italian patients exhibited significantly (p<0.001) more insertional calcific tendinopathy (heel spurs) and prominent posterosuperior calcaneal corners (Haglund's heel). CONCLUSION: ethnicity appears to be associated with specific characteristics of overuse-related Achilles tendon pathology. This is an issue that should be considered in the planning of genetic research on AT.

Surgical excision of posttraumatic ossifications at the proximal hamstrings in young athletes: technique and outcomes.

BACKGROUND: Proximal hamstring tears can be associated with chronic disability related to the unusual formation of heterotopic ossifications. The role for operative intervention in these circumstances has not been clearly defined. PURPOSE/HYPOTHESIS: The purpose of this study was to describe the surgical management of young athletes who had chronic disability related to proximal hamstring ossifications after eccentric load injuries. The hypothesis was that after surgical excision of posttraumatic heterotopic ossifications at the proximal hamstrings with concomitant repair of the tendons to the ischium, significant functional improvement with low risk of postoperative complications can be expected at minimum 2-year follow-up. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The cases of 11 consecutive male athletes who developed chronic disability associated with heterotopic ossifications at the proximal hamstring muscles after sports-related tears were reviewed. During surgery, the ossified mass was meticulously excised, and the tendons were debrided and fixed to the ischium. At minimum 2-year follow-up, self-reported outcome was rated as excellent, good, moderate, or poor. Operative reports and office visits were reviewed. Activity level before the injury and at latest follow-up was graded with the Tegner scale. RESULTS: The median age at injury was 17 years (range, 13-25 years). Sports activities included ice hockey, soccer, track and field athletics, and judo. Mean interval from injury to surgery was 45 months. The smallest ossified mass was 2 × 2 × 4 cm and the largest, 3 × 4 × 9 cm. Median follow-up was 4 years (range, 2-10 years). Six patients had excellent, 1 patient had good, and 4 patients had moderate outcomes; 7 of them were able to return to preinjury activities (Tegner score, 7-10). There were 2 cases of loss of skin sensation at the posterior femoral cutaneous nerve distribution, but neither patient described this as significantly interfering with any activity. All patients had symmetric side-to-side single-legged hop test and a 5 out of 5 on hamstring muscle strength at latest follow-up. CONCLUSION: Heterotopic ossifications that develop at the proximal hamstrings after eccentric load injuries can be associated with significant chronic disability. These cases can be effectively treated by surgical excision of the ossified masses and concomitant debridement with suture fixation of the proximal hamstring tendons to the ischium. Return to preinjury activities is expected in the majority of these cases, with low postoperative risks.

Clinical principles in the management of hamstring injuries.

PURPOSE: Hamstring injuries are among the most common muscle injuries seen in sports clinical practice. This narrative review covers essential knowledge of hamstring injuries, ranging from strains to total proximal three-tendon ruptures. The primary aim is to provide basic information for clinicians and sports medicine therapists dealing with hamstring problems. METHODS: In this review, existing literature of hamstring injuries was taken together. Emphasis was given to subjects less well covered in previous reviews, such as preventive measures, as well as the most relevant information needed in the treatment of these injuries. RESULTS: Occasionally, symptoms remain after hamstring injuries which can be successfully treated with surgery. Knowledge of the effectiveness of preventive measures and nonsurgical and surgical treatment is limited by small studies of low evidence level. CONCLUSIONS: Evidence-based treatment algorithms are not available. Larger studies of better quality with more concrete grading of hamstring tears are needed to improve knowledge in prevention and treatment of hamstring injuries. LEVEL OF EVIDENCE: IV.

Macroscopic Anomalies and Pathological Findings in and Around the Achilles Tendon: Observations From 1661 Operations During a 40-Year Period.

BACKGROUND: Nonsurgical treatments for chronic Achilles tendinopathy (AT) results in unpredictable success rates. Surgical treatment may be chosen as reports show mostly encouraging but variable success rates depending on the pathology. The distribution of surgically confirmed pathologies in AT is largely unknown. PURPOSE: To ascertain the distributions of macroscopically observed anomalies in participants undergoing surgical treatment for chronic AT. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The main macroscopic pathologies of 1661 chronic Achilles tendon overuse injuries, which were diagnosed and surgically treated by a single surgeon, were reviewed. The surgeries were performed on professional and recreational athletes during the years 1976-1980, 1986-1990, 1996-2000, and 2006-2010. Surgical diagnoses, along with age- and sport-specific characteristics, were collected retrospectively from patient records. RESULTS: The relative proportion of tendinosis increased during the study period from 4.2% to 21%, and paratenonitis decreased from 50% to 26%. Retrocalcaneal pathologies were the most common surgically confirmed lesions at 30%, while the mean age at surgery increased by 11 years over the entire study period. CONCLUSION: Surgically confirmed pathologies in and around the Achilles tendon showed coherent changes, chronic paratenonitis, and retrocalcaneal problems as the most prevalent findings. The classification of midportion and insertional tendinopathy and retrocalcaneal bursitis in AT should strictly be used as a clinical diagnosis. During surgical evaluations, the diagnosis is further clarified as more specific pathologies may be identified.

Calcific spurs at the insertion of the Achilles tendon: a clinical and histological study.

In active people, insertional calcific tendinopathy (CT) of the Achilles tendon is rare. We evaluated the results of surgical treatment for Achilles tendon CT and analyzed post-surgery Achilles tendon histological features. The study included 36 operations in 34 patients. Twenty-eight (78%) cases had a resection of a Haglund's deformity performed. The mean age of the patients was 42 years (range=23 to 68). Thirteen of the patients were professional athletes and 20 recreational athletes. In twenty-five (69%) cases, the result of surgery was rated good, in nine cases (25%) moderate and in two (6%) cases poor. The mean age of those with a good result was 10 years lower (40 versus 50 years) than those with a moderate result (p=0.0239). Higher athletic activity was also related to a better outcome (p=0.0205). Histology samples showed fast remodellation and stem-cell activation. Surgery seemed to result in a good outcome in patients with or without a Haglund's deformity which failed conservative treatment.

Triceps tears in athletes: different injury patterns and surgical treatment.

INTRODUCTION: Triceps muscle tears requiring surgical treatment are uncommon injuries. METHOD: We present 10 cases, all of them were athletes. All these patients were treated surgically between 1993 and 2009. Three operations were performed in the acute phase and the rest seven cases an average of 6 months (range 3-12 months) after the primary injury. The mean follow-up period after surgery was 6 years (range 2-9 years). RESULTS: The result was evaluated to be excellent in five cases, good in four, and fair in one patient. All except one patient were able to resume full training. CONCLUSION: Our results show that surgical treatment seems to be beneficial in severe triceps tears even after failed conservative treatment.

Proximal hamstring tendinopathy: results of surgical management and histopathologic findings.

BACKGROUND: Tendon disorders are common problems in sports and are known to be difficult to treat. Only limited information is available concerning treatment of proximal hamstring tendinopathy. To the authors' knowledge, no histopathologic findings of proximal hamstring tendinosis have been published. HYPOTHESIS: Surgery (semimembranosus tenotomy and exploration of the sciatic nerve) is an effective treatment for proximal hamstring tendinopathy. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 103 cases of proximal hamstring tendinopathy in athletes (58 men, 32 women; 13 bilateral operations) with surgical treatment were included. The cases were retrospectively analyzed, and a 4-category rating system was used to evaluate the overall result. At the follow-up, the patients were asked about possible symptoms and their return to sports. Biopsy samples from 15 of the operated tendons were taken and analyzed by a pathologist. RESULTS: The average follow-up was 49 months (range, 12-156 months). The result was evaluated to be excellent in 62 cases, good in 30, fair in 5, and poor in 6. After surgery, 80 of the 90 patients were able to return to the same level of sporting activity as before the onset of the symptoms. This took a mean of 5 months (range, 2-12 months). Typical morphologic findings of tendinosis were found in all biopsy specimens. CONCLUSION: Given the good functional outcome and low complication rate, the authors present surgical treatment as a valuable option in proximal hamstring tendinopathy if conservative treatment fails.

Complete proximal hamstring avulsions: a series of 41 patients with operative treatment.

BACKGROUND: Complete proximal hamstring avulsions can cause considerable morbidity and are often associated with significant functional loss. HYPOTHESIS: Early surgical treatment leads to better results than does surgery in the chronic phase. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Forty-one patients (21 men and 20 women) with a complete proximal hamstring avulsion were included. The cases were retrospectively analyzed, and a 4-category rating system was used to evaluate the overall result of the surgical treatment. RESULTS: The mean follow-up was 37 months (range, 12-72 months). Nineteen patients were rated as having an excellent result and 10 patients a good result. In 5 patients, the result was classified as moderate and in 7 patients poor. In the patients with an excellent or good result, the delay from the injury to surgery averaged 2.4 months, whereas in patients with a moderate or poor result, the delay averaged 11.7 months. The difference was statistically significant (P < .001). CONCLUSION: Excellent or good results can often be expected with surgery, and considerable improvement of symptoms may be achieved even in chronic cases. According to the results, early operative treatment in complete proximal avulsions of the hamstring muscles gives better results than does late surgery and is therefore recommended.
