RESUMO
PURPOSE: To compare outcomes after anterior cruciate ligament reconstruction (ACLR) with bone marrow aspirate concentrate (BMAC), demineralized bone matrix (DBM), and suture tape augmentation (STA) vs. ACLR without biologic augmentation or STA. METHODS: A prospective randomized controlled trial at a single institution was performed to compare ACLR with BMAC, DBM, and STA (Group A) vs. ACLR without biologic or STA (Group NA). One hundred patients were required. Skeletally mature patients <25 years old received quadriceps tendon autografts, while patients ≥25 years old received allograft ACLR with an all-inside technique. Concomitant meniscal pathologies were included. Primary outcomes compared were range-of-motion (ROM), limb symmetry, and patient-reported outcomes (PROs). Secondary outcomes included radiographic outcomes and surgical complications. Univariate and mixed-model regression analysis were used to compare outcomes. RESULTS: Fifty-nine patients were included (Group A: 29 patients, 11 females, 38%; Group NA: 30 patients, 15 females, 50%). Early range-of-motion at 6 weeks (125° vs 109° flexion, p<0.0001) and limb symmetry testing at 12 weeks (80.6 % vs. 36.7% [Delta 43.9%], p<0.001) were significantly improved in Group A. At two years, International Knee Documentation (IKDC) scores were similar (91.1 ± 12.7 vs. 85.3 ± 10.8, p=0.109). Knee Injury and Osteoarthritis and Outcome Score (KOOS) Quality of Life (QOL) scores were significantly enhanced in Group A (85.2 ± 20.9 vs. 72.1 ± 20.4, p=0.042). Twenty-two patients (12 Group A, 10 Group NA) underwent CT scans at 6-months to compare bone tunnel healing. Overall, the mean increase in bone tunnel diameter was significantly smaller in Group A vs. NA. No difference in graft re-ruptures or re-operations was observed. Seven of 59 patients (11.9%) underwent re-operation for stiffness (A: 3 (10%) vs. NA: 4 (13%), p=1.0). CONCLUSION: There were no differences in IKDC scores between groups at 2-year follow-up. Functional outcomes including early range-of-motion and limb symmetry were significantly improved in patients who received ACLR with BMAC, DBM, and STA. ACLRACLR.ACLR.
RESUMO
PURPOSE: To compare postoperative pain and recovery after anterior cruciate ligament reconstruction (ACLR) in patients who received an adductor canal block (ACB) or periarticular local infiltrative anesthesia (LIA). METHODS: A retrospective review of a prospectively collected ACL registry was performed. Patients underwent ACLR at a single institution between January 2015 and September 2020 and received long-acting local anesthesia with a preoperative ultrasound-guided ACB or periarticular LIA after surgery. Visual analog scale (VAS) pain scores, milligram morphine equivalents (MME) consumed in the post-anesthesia care unit (PACU), and total hospital recovery time were compared. Univariate analysis was used to compare VAS pain and MME totals between overall groups and groups propensity score matched for age, sex, body mass index, graft type, and meniscal treatment. Results are presented as mean (95%CI) unless otherwise indicated. RESULTS: There were 265 knees (253 patients) included (LIA, 157 knees; ACB, 108 knees). Overall, VAS pain scores before hospital discharge (LIA: 2.6 [2.4-2.8] vs ACB: 2.4 [2.1-2.7]; P = .334) and total MMEs were similar (LIA: 17.6 [16.4-18.8] vs ACB: 18.5 [17.2-19.8] (MME); P =.134). Median time to discharge also did not significantly differ (LIA: 137.5 [IQR: 116-178] vs. ACB: 147 [IQR: 123-183] (min); P = .118). Matched subanalysis (LIA and ACB; n = 94) did not reveal significant differences in VAS pain before discharge (LIA: 2.4 [2.1-2.7] vs ACB: 2.7 [2.4-3.0]; P = .134) or total MMEs (LIA: 18.6 (17.2-20.0) vs ACB: 17.9 (16.4-19.4); P = .520). CONCLUSION: The use of ACB or LIA resulted in similar early pain levels, opioid consumption, and hospital recovery times after ACLR surgery. LEVEL OF EVIDENCE: III, retrospective comparison study.

BACKGROUND: To evaluate the relationship between femoral version (FV) and α angle (AA) in a large osteological collection of human femurs. METHODS: The University of Iowa-Stanford osteological collection was used to evaluate the research aims. To measure FV and AA, axial photographs of the proximal femurs were taken, referenced from the posterior condylar axis. FV and AA measurements were obtained using ImageJ software, and the relationship between FV and AA was assessed with repeated-measures analysis of variance and generalized linear models. A P value of <.05 was considered statistically significant. RESULTS: A total of 1321 cadaveric femurs (666 left and 655 right) in 721 cadavers were examined. The average AA for all femurs was 47.8° ± 10.9°, and the average FV for all femurs was 8.53° ± 8.09°. Overall, 191 femurs (14.5%) exhibited cam morphology (AA ≥ 60°). Of the 721 cadavers, 600 had both femurs available for side-to-side comparison. The average FV of femurs with cam morphology was significantly higher than that of femurs without cam morphology (11.70° ± 8.82° vs. 7.99° ± 8.82°, P < .001). Linear regression analysis demonstrated that increased AA was significantly correlated with increased FV (ß ± standard error of the mean = 0.21 ± 0.02, P < .0001). CONCLUSION: In a large osteological collection of human femurs, a significant positive relationship between AA and increasing FV was identified. CLINICAL RELEVANCE: FAI and hip impingement morphology are more complex than cam or pincer morphology. Cam morphology with high femoral anteversion may allow for normal or near-normal hip mechanics without impingement, and this may partially explain the high rates of asymptomatic cam-type femoroacetabular impingement (FAI) morphology in active and general populations. Given the multiple morphological factors implicated in the development of FAI syndrome, these findings warrant further investigation.

PURPOSE: To compare postoperative pain and early recovery after hip arthroscopy with and without a perineal post for joint distraction. METHODS: We retrospectively reviewed a consecutive series of patients who underwent hip arthroscopy before and after the adoption of a postless technique. Patients who underwent concurrent periacetabular or femoral osteotomy were excluded. Demographic information, procedure variables, and visual analog scale (VAS) pain scores were recorded. Analgesic medications given were converted to morphine milligram equivalents (MME) for comparison. Uni- and multivariate analyses were conducted to compare total MME, postoperative pain, and time to discharge between groups. RESULTS: One hundred patients were in each group. The overall age (mean ± standard deviation) was 26.5 ± 9.9 years (Post [P]: 57 females; No Post [NP]: 68 females). Total operative time (P 100.4 ± 17.9 minutes vs NP 89.1 ± 25.5 minutes, P = .0004), traction time (P 45.8 ± 10.3 minutes vs NP 40.9 ± 11.1 minutes, P = .0017), and operating room time (P 148.8 ± 19.3 minutes vs NP 137.3 ± 25.8 minutes, P = .0005) were found to be shorter in the NP group. Total MME, and final VAS pain scores in the PACU were similar between both groups (MME, P = .1620; VAS, P = .2139). Time to discharge was significantly shorter in the NP group (P 207.2 ± 58.8 vs NP 167.5 ± 47.9, P < .0001). Patient age (≥25 years) (65.2 ± 18.1 vs 59.8 ± 15.7 [MME], P = .0269) and elevated body mass index (≥25) (65.1 ± 17.1 vs 59.3 ± 16.4 [MME], P = .0164) were factors associated with greater total MME consumption. Female sex was associated with higher postoperative VAS pain scores (FM 4.1 ± 1.6 vs M 3.4 ± 1.8 P = .0027). CONCLUSIONS: Adoption of the postless technique did not result in prolonged operating room or operative time. Overall, both groups had similar postoperative pain, however, the time from surgery to hospital discharge was shorter in the postless group. LEVEL OF EVIDENCE: III, retrospective comparison study.

Many if not most of us watched in utter disbelief and horror last September 11th as Aaron Rogers, the newly acquired $75 million dollar quarterback with the New York Jets just 4 snaps into the new season, suffered an Achilles Tendon ruptures (ATR) in his inaugural game on nationally televised Monday Night Football with his new and excited team and demanding fanbase. With cell phones in hand, we watched as our X apps lit up with claims of an excess of ATRs in the NFL in recent years and much of the blame placed on the new rubberized turf surfaces in place in most of the NFL stadiums. That first week of the NFL season the NFL Players Association, the NFLPA, put out a statement to this effect that demanded removal of rubberized turf surfaces throughout the NFL! With Kirk Cousins devastating ATR a few weeks later, amongst 21 others this season, and Aaron Rogers return to practice after a mere seven to eight weeks post-injury, this conundrum remains foremost in our hyper-questioning minds!
RESUMO
It is unclear if bracing is necessary after isolated medial patellofemoral ligament reconstruction (MPFLr) for recurrent patellar instability. We hypothesize that patients who did not use a brace will have similar outcomes to those who were braced postoperatively. A retrospective review of patients who underwent isolated MPFLr from January 2015 to September 2020 at a single institution was performed. Those with less than 6 weeks of follow-up were excluded. The braced group was provided a hinged-knee brace postoperatively until the return of quadriceps function, which was determined by the treating physical therapist (brace, "B"; no brace, "NB"). Time to straight leg raise (SLR) without lag, recurrent instability, and total re-operations were determined. Univariate analysis and logistic regression were used to evaluate outcomes (statistical significance, p < 0.05). Overall, 229 isolated MPFLr were included (B: 165 knees, 146 patients; NB: 64 knees, 58 patients). Baseline demographics were similar (all p > 0.05). Median time to SLR without lag was shorter in the NB group (41 days [interquartile range [IQR]: 20-47] vs. 44 days [IQR: 35.5-88.3], p = 0.01), while return to sport times were equivalent (B: 155 days [IQR: 127.3-193.8] vs. NB: 145 days [IQR: 124-162], p = 0.31). Recurrent instability rates were not significantly different (B: 12 knees [7.27%] vs. NB: 1 knee [1.56%], p = 0.09), but the re-operation rate was higher in the brace group (20 knees [12.1%] vs. 0 [0%], p = 0.001). Regression analysis identified brace use (odds ratio [OR]: 19.63, 95% confidence interval [CI]: 1.43-269.40, p = 0.026) and female patients (OR: 2.79, 95% CI: 1.01-7.34, p = 0.049) to be associated with needing reoperation. Recurrent instability rates and return to sport times were similar between patients who did or did not use a hinged knee brace after isolated MPFLr. Re-operation rates were higher in the braced group. Retrospective Comparative Study, Level III.

Background: Wrestling is known to be a sport of relatively high injury incidence, and knee injuries account for a large percentage of those injuries. Treatment of these injuries varies considerably depending on injury and wrestler characteristics, leading to variability in complete recovery and return to sport (RTS). The purpose of this study was to evaluate injury trends, treatment strategies, and RTS characteristics after knee injuries in competitive collegiate wrestling. Methods: NCAA Division I collegiate wrestlers who sustained knee injuries between January 2010 and May 2020 were identified using an institutional Sports Injury Management System (SIMS). Wrestling-related knee, meniscus, and patella injuries were identified, and treatment strategies were documented to investigate potential recurrent injury trends. Descriptive statistics were used to quantify the number of days, practices, and competitions missed, return to sport times, and recurrent injuries among wrestlers. Results: Overall, 184 knee injuries were identified. After excluding non-wrestling injuries (n=11), 173 injuries remained (77 wrestlers). The mean age at time of injury was 20.8 ± 1.4 years, and the mean BMI was 25.9 ± 3.8 kg/m2. There were 135 primary injuries (74 wrestlers), which consisted of 72 (53%) ligamentous injuries, 30 (22%) meniscus injuries, 14 patellar injuries (10%), and 19 other injuries (14%). The majority of ligamentous injuries (93%) and patellar injuries (79%) were treated non-operatively, while the majority of meniscus tears (60%) underwent surgery. Twenty-three wrestlers (22%) sustained recurrent knee injuries, of which 76% were treated non-operatively after their initial injury. Recurrent injuries consisted of 12 (32%) ligamentous injuries, 14 (37%) meniscus injuries, eight (21%) patellar injuries, and four (11%) other injuries. Fifty percent of recurrent injuries were treated operatively. When comparing recurrent injuries to primary injuries, recurrent injuries had a significantly longer return to sport time (Recurrent 68.3 ± 96.0 days vs. Primary 26.0 ± 56.4 days, p=0.01). Conclusion: The majority of NCAA Division I collegiate wrestlers who sustained knee injuries were initially treated non-operatively, and approximately one in five wrestlers sustained recurrent injuries. Return to sport time was significantly increased after a recurrent injury. Level of Evidence: IV.

BACKGROUND: Anterior inferior iliac spine (AIIS) impingement has been increasingly recognized as a source of extra-articular impingement and hip pain. However, no aggregate data analysis of patient outcomes after AIIS decompression has been performed. PURPOSE: To evaluate outcomes after arthroscopic AIIS decompression. STUDY DESIGN: Meta-analysis; Level of evidence, 4. METHODS: A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed, EMBASE, and Cochrane Central Register of Controlled Trials were queried for all English-language studies reporting outcomes of arthroscopic AIIS decompression performed in isolation or in conjunction with hip impingement correction surgery. After screening, 10 articles were included. The indications for AIIS decompression were recorded, and weighted mean improvements in patient-reported outcome (PRO) scores, complication rates, and revision rates were calculated. RESULTS: A total of 547 patients (311 women; 57%) were identified, with a total of 620 operative hips. The mean age was 28.42 ± 5.6 years, and the mean follow-up was 25.22 ± 11.1 months. A total of 529 hips (85%) underwent AIIS decompression, 530 hips (85%) underwent femoral osteochondroplasty, and 458 hips (74%) underwent labral repair. Of the patients, 13% underwent bilateral AIIS decompression. The mean modified Harris Hip Score improved from 61.3 ± 6.9 to 88.7 ± 4.7 postoperatively (change, 27.4 ± 5.7 points; P < .001), the Hip Outcome Score-Activities of Daily Living improved from 67.2 ± 10.6 to 91.1 ± 3.2 postoperatively (change, 24.0 ± 8.0 points; P = .001), and the Hip Outcome Score-Sports Specific Subscale improved from 36.8 ± 19.2 to 82.8 ± 3.8 postoperatively (change, 46.0 ± 18.2 points; P = .002). The pooled risk of postoperative complications was 1.1% (95% CI, 0.1%-2.1%), and the pooled risk of needing revision surgery was 1.0% (95% CI, 0.1%-2.0%). No complication was directly attributed to the AIIS decompression portion of the procedure. CONCLUSION: PROs improved significantly after hip arthroscopy with AIIS decompression, with a low risk of postoperative complications and subsequent revision surgeries. Failure to identify extra-articular sources of hip pain in outcomes of femoroacetabular impingement syndrome, including from the AIIS, could lead to poorer outcomes and future revision surgery.

Background: To perform a systematic review to evaluate the incidence of capsulolabral adhesions following hip arthroscopy (HA) for femoroacetabular impingement (FAI); including risk factors and post-treatment outcomes. Methods: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we queried PubMed, EMBASE, and Cochrane Central Register of Controlled Trials for English-language studies with minimum 6-month follow-up after primary or revision HA for FAI, which reported the incidence of capsulolabral adhesions. Potential adhesion risk factors, such as anchor type used and protocol for capsule closure, were assessed. Pre-operative and post-operative modified Harris Hip Score (mHHS) values were compared in studies that reported them. Results: Thirty-seven articles were included (24 primary HA; 13 revision HA). There were 6747 patients who underwent primary HA (6874 hips; 3005 female, 44%). The incidence of capsulolabral adhesions, confirmed surgically during revision HA, was low. Patients undergoing surgical treatment reported postoperative improvement per modified Harris Hip Scores. Data for 746 patients undergoing second revision HA (761 hips; 449 female, 60%), showed an incidence of adhesions greater than that of primary HA patients. Conclusion: While the incidence of symptomatic capsulolabral adhesions after primary hip arthroscopy is low; revision hip arthroscopy is strongly associated with adhesion development. Lysis of adhesions in primary hip arthroscopy patients reliably improved patient-reported outcomes. Level of Evidence: IV.

Purpose: to compare immediate post-operative pain and patient-reported outcomes (PROs) after partial meniscectomy with needle (NA) vs. standard (SA) arthroscopy technique. Methods: A retrospective review of a consecutive series of patients who underwent partial meniscectomy before and after adoption of a needle arthroscopic technique was performed. Meniscus repairs, root repairs, and those with ligamentous injuries were excluded. Total milligram morphine equivalents (MMEs) consumed, Visual analog scale (VAS) pain, and Knee Injury and Osteoarthritis Outcome Scores (KOOS) were compared pre-operatively and at 2 and 6-weeks postoperatively. Univariate analysis was used to compare results. Results: Nineteen patients were in each group (NA: 10 females, SA: 11 females). Mean ± SD age (NA 42.8 ± 8.4 vs. SA 47.6 ± 10.4 years, p = 0.13) and body mass index (NA 31.4 ± 5.6 vs. SA 35.1 ± 5.4 m/kg2, p = 0.06) were not significantly different. Seventeen (89%) patients in both groups had medial meniscus tears of the posterior horn. Preoperative Outerbridge score was significantly greater in the SA group (3.4 vs. 1.8, p = 0.002); however, preoperative VAS pain (NA 6.1 ± 1.7 vs. SA 6.1 ± 1.8, p = 0.98) and KOOS pain (NA 44 ± 17% vs. SA 37 ± 12.5%, p = 0.20) were similar. Amount of arthroscopic fluid used was significantly greater in the SA vs. NA group (1.4 ± 0.7 vs. 0.5 ± 0.3 L, p < 0.0001), but tourniquet time was equivalent (NA 20 ± 6 vs.16 ± 6 min, p = 0.11). VAS pain scores (NA 1.0 ± 1.1 vs. SA 2.6 ± 1.5, p = 0.0014), KOOS pain (NA 79 ± 15% vs. 58 ± 19%, p = 0.0006), and Quality of Life (QOL) scores (NA 70 ± 22% vs. SA 43 ± 24%, p = 0.001) were significantly better at 2-weeks post-op in the N group. By 6 weeks post-op, all PROs including VAS pain and KOOS scores were similar between groups. Conclusions: Adoption of a needle arthroscopic technique for partial meniscectomy was associated with significantly improved VAS and KOOS pain scores two-weeks post-operatively. Differences were not sustained at 6 weeks after surgery. Level of evidence: III, Retrospective Comparison Study.
RESUMO
The Femoro-Epiphyseal Acetabular Roof (FEAR) index is a newer measurement to identify the hip instability with borderline acetabular dysplasia. The purpose of this study is to (i) validate the FEAR index in determining the stability of the hip in patients who have previously been treated surgically for femoroacetabular impingement (FAI) and/or developmental dysplasia of the hip (DDH) and (ii) to examine the relationship between the FEAR index and femoral version, lateral center edge angle, Tönnis angle and alpha angle (AA). Patient demographics and radiographic measurements of 215 hips (178 patients), 116 hips treated with hip arthroscopy for FAI and 99 hips treated with periacetabular osteotomy (PAO) for DDH were compared between groups. The sensitivity and specificity of the FEAR index to detect the surgical procedure performed (PAO or hip arthroscopy) was calculated, and a threshold value was proposed. Pearson's correlation coefficients were used to describe the relationships between the FEAR index, femoral version and other radiographic measurements. The FEAR index was higher in patients with DDH versus FAI (DDH: 2.81 ± 0.50° versus FAI: -1.00 ± 0.21°, P < 0.001). A FEAR index threshold value of 3° had a sensitivity and specificity of 80% and 81%, respectively, for correctly predicting the surgical procedure performed. Femoral version was positively associated with the FEAR index in the setting of DDH (r = 0.36, P = 0.001) but not FAI (r = 0.02, P = 0.807). A FEAR index of 3° predicted treatment with 80% sensitivity and 81% specificity. In addition, femoral version significantly correlates with the FEAR index in the setting of DDH but not FAI.
RESUMO
PURPOSE: To evaluate femoral and acetabular morphology in patients who underwent anterior cruciate ligament reconstruction (ACLR). METHODS: A retrospective review of a prospectively collected ACL registry was performed to identify patients with pelvis radiographs before undergoing either primary or revision ACLR between January 2010 and August 2020. Alpha angle (AA), head-neck offset ratio (HNOR), lateral center edge angle (LCEA), and crossover sign (COS) were measured on the operative side. Values were compared to a negative control group that did not significantly differ in age, sex, or body mass index. Univariate analysis and Pearson's correlation coefficient were used to compare groups with significance defined as P < .05. RESULTS: In total, 114 patients were included (ACL, n = 38; control, n = 76). Eleven primary and 27 revision ACL reconstructions were identified. The mean AA in patients undergoing primary ACL reconstruction was higher than control (67.45° ± 11.30° vs 51.5° ± 10.8°, P < .001). A significantly elevated AA was also found in those undergoing revision ACL surgery (61.8° ± 7.51° vs 51.5° ± 10.8°, P < .001). In addition, the HNOR was significantly lower in the ACL group (0.12 ± 0.03 vs 0.14 ± 0.04, P = .0304). Acetabular morphology was similar between groups (LCEA, ACL 31.97° ± 5.04° vs control 30.01° ± 5.17°, P = .0549; COS, ACL 9 of 38 (23.7%) vs control 18 of 76 (23.7%), P = 1.00). CONCLUSION: An association exists between radiographic cam morphology of the hip and patients who previously underwent ACLR. LEVEL OF EVIDENCE: III, retrospective comparison study.
RESUMO
PURPOSE: We evaluate the incidence of heterotopic ossification (HO) development with nonsteroidal anti-inflammatory drug (NSAID) prophylaxis in patients after open and arthroscopic hip preservation surgery. METHODS: A retrospective review identified patients who underwent hip preservation surgery at a single institution within the past 3 years. Patients who underwent hip arthroscopy with or without periacetabular osteotomy (PAO) or femoral osteotomy (FO) were included. Those who did not receive 3-month postoperative radiographs were excluded. The incidence and Brooker classification (BC) of HO in patients taking Naproxen or another NSAID (meloxicam, celecoxib, indomethacin, or aspirin alone) was assessed using AP radiographs available from 3-, 6-, and 12-month follow-up appointments. Univariate analysis was conducted to compare numerical means and categorical data (significance level P = .05). RESULTS: A total of 328 hips (284 patients) were included. All patients received hip arthroscopy, while 71 patients (21.6%) received concurrent periacetabular osteotomy (PAO; n = 65) or femoral osteotomy (FO; n = 6). Overall, 276 hips (84.4%) received Naproxen for HO prophylaxis. In total, 5 of 328 hips (1.5%) developed HO (4, BC I; 1, BC III). The rate of HO development was significantly higher in males versus females (4 of 121 (3.31%) vs 1 of 207 (.48%), P = .0441). All 5 patients received arthroscopic cam resection and labral repair, and 1 patient also received PAO. Three patients in the Naproxen group (.91%) developed HO, which was not statistically different from those taking a different NSAID (.61%, P = .1797). CONCLUSION: The incidence of HO development was low with NSAID prophylaxis after hip preservation surgery.
RESUMO
Hip arthroscopy techniques have evolved to treat a wide range of extra-articular pathologies. Subspine impingement commonly occurs in femoroacetabular impingement, particularly in athletes with a high range of motion, patients with low degrees of femoral version, and those with large subspine deformities. A reliable technique that preserves the hip capsule would be helpful for hip arthroscopy surgeons. This note details our technique using pericapsular windows proximal to the interportal capsulotomy to access and decompress a subspine deformity in the setting of hip femoroacetabular impingement.
RESUMO
Background: Comprehensive conservative care prior to arthroscopic hip surgery is recommended, but not all patients pursue a course of physical therapy (PT) prior to consulting a hip surgeon. The purpose of this study is to investigate the incidence and type of PT administered to patients with hip pain prior to consulting a hip surgeon. Methods: We conducted a single-center, questionnaire-driven study at a young adult hip preservation clinic that exclusively treats patients with hip pain. Thirty (88%) of thirty-four consecutive new patients answered the 15-item questionnaire. The questionnaire was designed to inquire about the reason for the visit, type of formal PT received (hip strengthening, leg strengthening etc.), and additional treatments received prior to the visit (electric stimulation, narcotics etc.). Descriptive statistics were utilized to quantify the reason for visit, PT prior to the visit, and type of exercises performed during physical therapy. Results: Overall, 21 (70%) patients received physical therapy prior to consulting with a hip surgeon. Of those who received PT, 91% (n=19) did hip strengthening exercises, 76% (n=16) did focused hip stretching exercises, 62% (n=13) did leg strengthening exercises, 57% (n=12) did joint mobilization exercises, and 52% (n=11) did focused core strengthening exercises. Only 48% (n=10) reported improvement in symptoms with PT. Of those who received additional treatments, 77% (n=20) took anti-inflammatory medications regularly, 50% (n=13) underwent electric stimulation, 31% (n=8) had chiropractic manipulation, 19% (n=5) underwent soft tissue mobilization, 15% (n=4) received steroid injections, and 12% (n=3) were prescribed narcotics for hip pain. Conclusion: The present study offers insight into the incidence and type of formal PT patients with hip pain receive before consulting a hip surgeon. Treatment methods during PT visits are variable, which makes determining outcomes of conservative care difficult to assess in this population.Level of Evidence: IV.

Background: The purpose of the present study is to determine the association between femoral version and traditional pathologic bony factors commonly used to measure and define patellofemoral alignment. Methods: We performed a retrospective review of patients treated for patellofemoral instability (PFI) at a single institution. Patients included underwent magnetic resonance imaging (MRI) of the lower extremity using a rotational protocol prior to medial patellofemoral ligament reconstruction with or without tibial tubercle osteotomy. Those with a history of ipsilateral lower extremity surgery were excluded. Two independent reviewers measured femoral version, tibial tubercle-trochlear groove (TT-TG) distance, tibial tubercle-posterior cruciate ligament (TT-PCL) distance, and tibial torsion (TT). Pearson correlation coefficients were used to describe the relationships between all radiographic measures. Results: A total of 51 knees (43 patients) were included. The average age and body mass index were 23.7 ± 9.33 years and 29.23 ± 8.04 kg/ m2, respectively. The mean femoral version was 15.61 ± 11.57°. The degree of femoral version did not significantly correlate with TT-TG (r=0.103, p=0.474), TT-PCL (-0.086, p=0.550), or TT (r=0.111, p=0.438). Increased TT-TG distance was strongly associated with increased TT-PCL (r=0.470, p=0.001). In females, increased femoral version significantly correlated with increased TT (r=0.381, p=0.029). Conclusion: Neither increased nor decreased amounts of femoral anteversion significantly correlated with TT-TG, TT-PCL, or TT. Therefore, assessment of femoral version should be measured independently of conventional measures when considering osteotomies to correct PFI.Level of Evidence: IV.

BACKGROUND: The purpose of this study was to evaluate the influence of the volume and type of sport on the development of cam-type femoroacetabular impingement and acetabular dysplasia. METHODS: The Physical Activity Questionnaire for Adolescents (PAQ-A) was administered to Iowa Bone Development Study participants at the age of 17 years to identify those who had participated in at least 2 seasons of high school interscholastic sports. Based on relative peak strain and ground reaction forces, subjects were grouped as power sport athletes (basketball, cheerleading, football, gymnastics, soccer, and volleyball), non-power sport athletes (wrestling, baseball, cross-country or track and field, softball, or tennis), or non-athletes. Using anteroposterior views of the left hip formatted from dual x-ray absorptiometry (DXA) scans, the alpha angle, head-neck offset ratio (HNOR), and lateral center-edge angle (LCEA) were evaluated longitudinally at the ages of 17, 19, and 23 years. Logistic regression was used to evaluate the odds of hip cam morphology (alpha angle >55° and/or HNOR <0.17) or acetabular dysplasia (LCEA <24°) at the age of 23 years in all athlete groups. The relationships between physical activity level and hip measures (alpha angle, HNOR, and LCEA) from the ages of 17 to 23 years were examined using linear mixed models adjusted for sex. RESULTS: Compared with non-athletes at the age of 23 years, power sport athletes had significantly greater odds of cam morphology according to the alpha angle (odds ratio [OR], 2.93 [95% confidence interval (CI), 1.02 to 8.41]; p = 0.046) and HNOR (OR, 1.91 [95% CI, 1.01 to 3.60]; p = 0.047), but not greater odds of acetabular dysplasia (p > 0.05). There were no significant differences in the odds of cam morphology or acetabular dysplasia in non-power sport athletes compared with non-athletes (all p > 0.05). Higher physical activity levels were significantly associated with an increase in the alpha angle (beta and standard error, 0.77° ± 0.30°; p = 0.011) and a decrease in the HNOR (-0.003 ± 0.001; p = 0.003), but not the LCEA (-0.05 ± 0.15; p = 0.744). CONCLUSIONS: A higher volume of physical activity and participation in sports with higher peak strain and ground reaction forces during the process of skeletal maturation may increase the risk of developing cam morphology during late adolescence.
