Introduction: Preoperative estimation of graft parameters can be useful while using hamstring grafts in knee ligament surgeries. Anthropometric parameters may be an easy way to predict the length and diameter of hamstring tendons. A prospective study was conducted to find the correlation between different anthropometric parameters and activity level of the patient on the length and diameter of the graft. Separate regression equations for males and females were also derived for easy prediction. Methods: Data were obtained from 95 patients who underwent arthroscopic anterior cruciate ligament reconstruction with autologous hamstring tendon graft. Variables studied were age, sex, height, weight, body mass index (BMI), thigh circumference, thigh length, Tegner activity level, diameter (double and quadruple) and length of semitendinosus tendon graft. Results: Height of the patient had strong correlation with graft length (r = 0.41, p < 0.001), double diameter (r = 0.29, p = 0.008) and quadruple diameter (r = 0.3, p = 0.006). Weight of the patients had strong positive correlation with graft length (r = 0.34, p = 0.002) and quadruple diameter (r = 0.34, p = 0.002). Thigh length was found to be positively correlating with graft length (r = 0.43, p < 0.001), double diameter (r = 0.29, p = 0.007) and quadruple diameter of graft (r = 0.34, p = 0.002). BMI and thigh circumference of the patients were not found to correlate with graft size. Male patients were found to have longer semitendinosus graft and larger double and quadruple diameter of the graft. There was no association between the Tegner activity scale and graft size. Regression equations between graft length and quadruple diameter and the anthropometric parameters are also derived. Conclusion: Height, weight and thigh length are useful anthropometric parameters in the prediction of hamstring tendon size. However, the patient’s Tegner activity level was not found to be associated with size of the hamstring tendon.

Introduction Autologous platelet rich plasma (PRP) local injection has been recently proposed as a treatment of plantar fasciitis. The autologous PRP does not have much side effects compared to steroid injections. So far PRP injections have shown promising results in various studies. This study assessed the efficacy of a single local injection of PRP in chronic unilateral plantar fasciitis through a prospective case series. Methodology A hospital-based prospective case series of 30 unilateral plantar fasciitis patients with symptom duration of 6 months or more were included in the study. All patients included in the study were assessed clinically and by visual analogue score for heel pain, AHS component of AOFAS and FADI scores before injection and at 6 and 12 week followup. USG measurement of plantar fascia thickness was done at pre-injection and at 12 weeks follow-up. All patients were observed for 12 weeks. ResultsThe mean age was 39 years (range 20-55 years). The pre-injection VAS score for heel pain was 6.5 ± 1.1 which improved to 2.7 ± 0.5 and 1.8 ± 0.8 at 6 and 12 week respectively and difference was significant (p < 0.001). The baseline FADI and AHS component of AOFAS scores were 53.1 ± 9.0 and 72.2 ± 5.7 which improved to 65.5 ± 5.3 and 76.1 ± 4.5 at 6 weeks and, 77.9 ± 4.4 and 85.7 ± 4.6 at 12 weeks respectively which was significant (p < 0.001). The baseline mean plantar fascia thickness was 4.9 ± 0.3 mm which was significantly (p < 0.001) reduced to 3.9 ± 0.3 mm at 12 weeks post PRP injection. All pairwise comparisons by the post-hoc Wilcoxon signed rank test with p-value adjustment were also significant. ConclusionThe short-term results of single dose PRP injections shows clinical and statistically significant improvements in VAS for heel pain, functional outcome scores and plantar fascia thickness measured by USG. This study concludes that local PRP injection is a viable management option for chronic plantar fasciitis.

Purpose This article aims to evaluate patterns of chronic multiligament injuries and outcomes of treatment with single-stage reconstruction using autografts. Methods All patients with clinicoradiologically diagnosed multiligament knee injury (MKI) were included in this prospective observational study. As the time since injury was more than 6 weeks in all of the patients, they were categorized as having chronic MKI. Patients were assessed clinically for laxity, and the diagnosis was confirmed radiologically. Ipsilateral hamstring tendons were used for medial collateral ligament (MCL) or posterolateral corner reconstruction in a patient with Schenck knee dislocation (KD) type III. In these cases, the posterior cruciate ligament (PCL) and anterior cruciate ligament (ACL) were reconstructed by using the peroneus longus and contralateral hamstring tendons respectively. Ipsilateral hamstring tendons were used for ACL reconstruction and an ipsilateral peroneus longus tendon graft was used for reconstruction of the PCL in a KD type II injury. In two cases of KD type IV injury, the lateral laxity was only grade II and was managed conservatively; the rest of the ligaments were addressed like a KD type III injury. Outcome evaluation was done using a visual analogue scale (VAS) for pain, International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner activity level, preoperatively and postoperatively at 2 years’ follow-up. Results A total of 27 patients of mean age 33.48 ± 9.9 years with MKI were included in the study. The patients were classified as eight KD type II, 17 KD type III, and two KD type IV. The majority of the patients had associated meniscal (59.2%) or chondral (40.7%) injuries. At the 2 years’ follow-up visit, there were significant improvements in VAS score (p = 0.0001) IKDC score (p = 0.0001), Lysholm score (p = 0.0001), and range of motion (p = 0.001). None of the patients had residual laxity on clinical examination of the knee joint at the 2 years’ follow-up. All but two of the patients went back to their previous activity level. These two patients had progressive knee arthritis and needed knee arthroplasty. Conclusion Single-stage surgical reconstruction for chronic MKI has favourable functional outcomes. Level of evidence Level IV, case series.
