Sixty-one shoulders in 57 adolescents underwent primary arthroscopic shoulder stabilization for labral tears sustained during contact sports (all Stanmore type 1). Mean follow-up was 22 months, mean age 16.8 (13-18) years. Postoperatively, the median subjective improvement was 90%, median VAS pain was 0 and mean Oxford Instability Score was 26.8. Sixty-one per cent returned to preinjury sporting level. A higher than expected proportion reported recurrent dislocation, with 15% followed up for 1 year and 31% for 4 years. Of these 11 requiring further surgery, 90% of redislocations occurred while playing rugby. Sex, type of sport, hyperlaxity and tear morphology were not significantly related to recurrence. Adolescents are at high risk for recurrence following arthroscopic stabilization. Patients should be counselled for the higher recurrence rate and consideration should be made for other aetiological factors such as returning to contact sports and joint hyperlaxity.
Purpose This study aimed to determine whether unrestricted weight-bearing as tolerated (WBAT) following lateral locking plate (LLP) fixation of periprosthetic distal femoral fractures (PDFFs) is associated with increased failure and reoperation, compared with restricted weight-bearing (RWB). Materials and methods In a retrospective cohort study of consecutive patients with unilateral PDFFs undergoing LLP fixation, patients prescribed WBAT were compared with those prescribed 6 weeks of RWB. The primary outcome measure was reoperation. Kaplan–Meier and Cox multivariable analyses were performed. Results There were 43 patients (mean age 80.9 ± 11.7 years, body mass index 26.8 ± 5.7 kg/m2 and 86.0% female): 28 WBAT and 15 RWB. There were more interprosthetic fractures in the RWB group (p = 0.040). Mean follow-up was 3.8 years (range 1.0–10.4). Eight patients (18.6%) underwent reoperation. Kaplan–Meier analysis demonstrated no difference in 2-year survival between WBAT (80.6%, 95% CI 65.3–95.9) and RWB (83.3%, 95% CI 62.1–100.0; p = 0.54). Cox analysis showed increased reoperation risk with medial comminution (hazard ratio 10.7, 95% CI 1.5–80; p = 0.020) and decreased risk with anatomic reduction (hazard ratio 0.11, 95% CI 0.01–1.0; p = 0.046). Immediate weight-bearing did not significantly affect the risk of reoperation compared with RWB (relative risk 1.03, 95% CI 0.61–1.74; p = 0.91). Conclusions LLP fixation failure was associated with medial comminution and non-anatomic reductions, not with postoperative weight-bearing. Medial comminution should be managed with additional fixation. Weight-bearing restrictions additional to this appear unnecessary and should be avoided.
Aims Debate continues regarding the optimum management of periprosthetic distal femoral fractures (PDFFs). This study aims to determine which operative treatment is associated with the lowest perioperative morbidity and mortality when treating low (Su type II and III) PDFFs comparing lateral locking plate fixation (LLP-ORIF) or distal femoral arthroplasty (DFA). Methods This was a retrospective cohort study of 60 consecutive unilateral (PDFFs) of Su types II (40/60) and III (20/60) in patients aged ≥ 60 years: 33 underwent LLP-ORIF (mean age 81.3 years (SD 10.5), BMI 26.7 (SD 5.5); 29/33 female); and 27 underwent DFA (mean age 78.8 years (SD 8.3); BMI 26.7 (SD 6.6); 19/27 female). The primary outcome measure was reoperation. Secondary outcomes included perioperative complications, calculated blood loss, transfusion requirements, functional mobility status, length of acute hospital stay, discharge destination and mortality. Kaplan-Meier survival analysis was performed. Cox multivariate regression analysis was performed to identify risk factors for reoperation after LLP-ORIF. Results Follow-up was at mean 3.8 years (1.0 to 10.4). One-year mortality was 13% (8/60). Reoperation was more common following LLP-ORIF: 7/33 versus 0/27 (p = 0.008). Five-year survival for reoperation was significantly better following DFA; 100% compared to 70.8% (95% confidence interval (CI) 51.8% to 89.8%, p = 0.006). There was no difference for the endpoint mechanical failure (including radiological loosening); ORIF 74.5% (56.3 to 92.7), and DFA 78.2% (52.3 to 100, p = 0.182). Reoperation following LLP-ORIF was independently associated with medial comminution; hazard ratio (HR) 10.7 (1.45 to 79.5, p = 0.020). Anatomical reduction was protective against reoperation; HR 0.11 (0.013 to 0.96, p = 0.046). When inadequately fixed fractures were excluded, there was no difference in five-year survival for either reoperation (p = 0.156) or mechanical failure (p = 0.453). Conclusion Absolute reoperation rates are higher following LLP fixation of low PDFFs compared to DFA. Where LLP-ORIF was well performed with augmentation of medial comminution, there was no difference in survival compared to DFA. Though necessary in very low fractures, DFA should be used with caution in patients with greater life expectancies due to the risk of longer term aseptic loosening.

Background: There has been a shift toward functional nonoperative rehabilitation in the treatment of Achilles tendon rupture (ATR) despite a shortage of studies directly comparing nonoperative functional rehabilitation with traditional nonoperative immobilization. Purpose: To compare patient-reported outcome measures and functional outcomes for nonoperatively treated ATR with traditional cast immobilization or functional rehabilitation in a walking boot. Study Design: Randomized controlled clinical trial; Level of evidence, 2. Methods: In a single-center nonblinded study, 140 patients were randomized to compare treatment for acute ATR in (1) an immobilizing cast in reducing degrees of equinus over a 10-week period with 8 weeks of nonweightbearing mobilization or (2) a walking boot for 8 weeks with reducing equinus and immediate full weightbearing. Exclusion criteria were delayed presentation >2 weeks after injury, tendon reruptures, and latex allergy. Analysis was undertaken on an intention-to-treat basis. Results: A total of 69 patients (median age, 41 years [interquartile range, 33-50.5 years]) were randomized to walking boot treatment and 71 patients (41 [32-49]) to cast treatment. At 6 months, patients treated in a walking boot reported better Short Musculoskeletal Function Assessment (SMFA) dysfunction index (6.62 [2.21-12.50] vs 10.66 [4.96-13.42]; P = .050), SMFA bother index (7.29 [2.08-14.58] vs 10.42 [5.73-19.27]; P = .04), Achilles Tendon Total Rupture Score (71.5 [53.50-84.25] vs 54.0 [37-76]; P = .01), and Foot and Ankle Questionnaire core score (91 [81.89-97.55] vs 85 [78.25-92.09]; P = .04). At 1 year, there was no difference in SMFA dysfunction index (2.21 [0.74-5.88] vs 2.94 [1.47-6.62]; P = .25), SMFA bother index (2.08 [0-9.38] vs 5.21 [0.52-11.98]; P = .25), Achilles Tendon Total Rupture Score (92 [72.50-96] vs 87.5 [66.0-94.75]; P = .21), or Foot and Ankle Questionnaire core score (97.75 [89.46-99.00] vs 95.50 [90.88-97.50]; P = .18). Rerupture occurred in 5 and 11 patients ( P = .075) and venous thromboembolism in 2 and 3 patients ( P = .67) in the boot and cast groups, respectively. Fifteen patients in the boot group but none in the cast group had skin problems ( P < .001). Patients treated in a boot returned to driving at a median 12 weeks (vs 13 weeks for cast; P = .045), but there was no difference in time to return to work ( P = .48). Conclusion: Functional rehabilitation with early weightbearing is a safe alternative to traditional immobilizing treatment for ATR, giving better early functional outcomes, albeit with a higher incidence of transient minor skin complications.
